Emergency laparotomy for abdominal catastrophes secondary to lymphoma: A systematic review

Intestinal lymphomas can rarely present as abdominal catastrophes with perforation or small bowel obstruction. There is little data regarding their optimal surgical management and associated outcomes. We aimed to systematically review relevant published literature to assess the presentation, diagnosis, optimal surgical approach and associated post-operative outcomes. A systematic on-line literature search of Embase and Medline identified 1485 articles of which 34 relevant studies were selected, including 7 retrospective studies, 1 case series and 26 case reports. Selected articles were assessed by two reviewers to extract data. 95 patients with abdominal catastrophes secondary to lymphoma (predominately Burkitt (28 %) and Diffuse Large B-cell lymphoma (29 %)) were identified with a median age of 52 years, 40 % were female. Of the small bowel resections 25% (n = 18) suffered post-operative complications with a 13.8 % (n = 10) 30-day mortality. Ileocolonic resections had a 27 % complication rate with 18 % mortality and primary repair had a 25 % complications rate and 25 % mortality. Median follow-up was 8 days (range 1-96). Notable points of differences in the presentations between these different lymphomas included the majority of Burkitt's lymphoma were younger, had a known diagnosis, were on chemotherapy and presented with perforation in contrast to those with B cell lymphoma who were predominately older, had new diagnoses and presented with a balanced proportion of obstruction and perforation. Abdominal catastrophes secondary to intestinal lymphomas most commonly present with perforation. Aggressive surgical management, including small bowel resection, may offer similar remission rates for lymphoma patients presenting with abdominal catastrophes as those without such emergency complications.

Urgent Excision of Primary Intracardiac Burkitt Lymphoma in a Child

A 9-year-old girl presented with a recent history of shortness of breath, fatigue, visual disturbances, and gastrointestinal symptoms. Echocardiography demonstrated three large intracardiac masses in the right and left atria protruding into the mitral and tricuspid valve orifices causing bilateral inflow obstruction. She underwent urgent surgical excision of the masses. Histology revealed rare intracardiac Burkitt's Lymphoma.

Primary Burkitt lymphoma of the thyroid associated with Hashimoto's thyroiditis

Primary Burkitt lymphoma of the thyroid is an extremely rare entity with only a few reported cases. A female patient in her 70s with Hashimoto's thyroiditis presented with a 2-month history of progressive left-sided neck swelling. Ultrasound examination revealed a multinodular goitre and fine needle aspiration (FNA) showed no signs of malignancy. The rapid growth of the thyroid mass raised the concern of a lymphoproliferative process. After left thyroid lobectomy and histopathological examination, the diagnosis of Burkitt lymphoma was made and the patient was included in a randomised study providing chemotherapy following a dose adjusted EPOCH-R regimen. Clinical remission was reached after 6 cycles of chemotherapy. There were no signs of relapse on follow-up, 1.5 years after the end of the treatment. Fast growing thyroid nodules in HT warrant a high index of suspicion. Despite no signs of malignancy after FNA cytology, these nodules may need further investigations.

Gallbladder Burkitt’s lymphoma mimicking gallbladder cancer: A case report

BACKGROUND

Malignant lymphoma is a rare form of gallbladder malignancy. Most of these malignancies are diffuse large B-cell lymphomas or mucosa-associated lymphoid tissue-type lymphomas; however, Burkitt’s lymphoma of the gallbladder is extremely rare, and only two previous reports are available in the literature. Herein, we report a rare case of Burkitt’s lymphoma of the gallbladder mimicking gallbladder adenocarcinoma.

CASE SUMMARY

An 83-year-old man with no abdominal complaints was found to have a gallbladder tumor and periportal lymph node enlargement on computed tomography (CT) performed for hypertension screening. His laboratory data revealed slightly elevated serum levels of carcinoembryonic antigen and soluble interleukin 2 receptor. Imaging examinations revealed two irregular and contrast-enhanced masses extending into the gallbladder lumen, but these did not infiltrate the serosa. Moreover, a periportal lymph node had enlarged to 30 mm. Based on these findings, we diagnosed the patient as having gallbladder adenocarcinoma with lymph node metastasis, which was treated using bile duct resection with gallbladder bed resection and periportal lymph node dissection. However, the patient was finally diagnosed as having Burkitt’s lymphoma. Although the surgical margin was pathologically negative, recurrence was noted at the hepatic radical margin and superior pancreaticoduodenal lymph nodes on positron emission tomography/CT soon after discharge. Thus, he was referred to a hematologist and started receiving treatment with reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone.

CONCLUSION

Burkitt’s lymphoma can occur in the gallbladder. Biopsy can be useful in cases with findings suggestive of gallbladder malignant lymphoma.

[A Case of Cecal Burkitt's Lymphoma with Intussusception]

We report a case of ileocecal intussusception due to Burkitt's lymphoma(BL). A 14-year-old boy was admitted to our hospital for abdominal pain and diarrhea. He was diagnosed an intussusception by the ultrasonography and the CT scan. Laparoscopic ileocecal resection was performed. A diagnosis of BL was made on basis of pathological examination. He was transferred for the chemotherapy on postoperative day 8. We conclude that, if the intussusception associated with malignant lymphoma is assumed from the preoperative findings, we have to keep minimal surgical invasion and start postoperative chemotherapy immediately.

Comparison between children and adults intussusception. Description of two cases and review of literature

INTRODUCTION

Intussusception is a common condition in children, it is rare in adults. Adult intussusception differs from pediatric intussusception in various respects, including etiology clinical characteristics and therapy.

METHODS

We present and discuss a new case of intussusception in children and adults.

RESULTS

In child the Barium Enema x-ray examination is identified an endoluminal filling defect to refer to the apex of the invaginated loop at the rectal level, with slow ascent during the progressive injection of the radiopaque contrast medium. At the end of the procedure, incomplete reduction of the picture is documented. The patient undergoes emergency surgery where the presence of an ileo-ceco-colic invagination is documented. Intussusception is reduced by taxis. In the adult laparoscopic right hemicolectomy was performed. High-grade B-cell Burkitt's lymphoma was confirmed by immunohistochemistry.

DISCUSSION

In contrast to intussusceptions in children, in the adult population, a demonstrable etiology is found in most of the cases. In adults surgery is always indicated. The non-invasive resolutive intervention most commonly used in the child and best known consists in the rectal introduction of a radiopaque contrast medium (air or barium) at controlled pressure until.

CONCLUSIONS

Although intussusceptions occur at all ages, there are major differences in the clinical presentation, diagnostic approach, and management between pediatric and adult populations. Intussusception is remarkably different in these two age groups and it must be approached from a different clinical perspective.

KEY WORDS

Intussusception in children, Intussusception in adults, Intussusception symptoms, Radiology and treatment.

Burkitt lymphoma associated with human immunodeficiency virus infection and pulmonary tuberculosis: A case report

INTRODUCTION

The association of human immunodeficiency virus (HIV) infection with Burkitt lymphoma is related to the presence of Epstein Barr virus infection and the impact of the HIV antigen on the expansion of B-polyclonal cells. In Southeast Europe, the association is rare, and recognizing this is important in the therapeutic decision to increase patient survival rate. The association of HIV with Burkitt lymphoma and tuberculosis is even more rarely described in the literature.

PATIENT CONCERNS

We present the case of a 40-year-old patient who presented with a 3-week history of fever (max. 38.7 °C), painful axillary swelling on the right side, lumbar pain, gait disorders, headache, and night sweats. Clinical manifestations included marked weight loss (about 30 kg in the last 2 months before his admission).

DIAGNOSIS

A LyCD4 count of 38/μL and a HIV1 viral load of 384,000/mm3, classified the patient into a C3 stage. A biopsy of the right axillary lymph node was performed for suspected ganglionic tuberculosis due to immunodeficiency. Histopathological examination confirmed the diagnosis of Burkitt lymphoma. Cultures on Löwenstein-Jensen medium from sputum harvested at first admission were positive for Mycobacterium tuberculosis.

INTERVENTIONS

Highly active antiretroviral therapy, chemotherapeutic agents for Burkitt lymphoma, anti-tuberculous drug therapy, neurosurgical intervention of spinal cord decompression, and antibiotic therapy of the associated bacterial infection.

OUTCOME

Burkitt lymphoma disseminated rapidly, with central nervous system, spinal cord, osteomuscular, adrenal, and spleen involvement. The evolution under treatment was unfavorable, with patient death occurring 6 months after diagnosis.

CONCLUSIONS

The association of HIV infection with Burkitt lymphoma and tuberculosis is rare in the highly active antiretroviral therapy (HAART) era, posing prompt and multidisciplinary therapeutic management issues. Similar cases of HIV-TB and Burkitt lymphoma association have been described, but none of the other cases showed the involvement of the central nervous system or of the bilateral adrenal glands.

Autologous hematopoietic stem cell transplantation for human immunodeficiency virus associated gastric Burkitt lymphoma: A case report

RATIONALE

HIV-related lymphoma, especially non-Hodgkin lymphoma, is one of the most common malignant tumors in HIV/acquired immune deficiency syndrome (AIDS) patients. Autologous hematopoietic stem cell transplantation (AHSCT) for the patients with Burkitt lymphoma (BL) is needed to be further explored.

PATIENT CONCERNS

A 57-year-old man was hospitalized with intermittent pain on upper abdomen and melena for >1 month.

DIAGNOSIS

HIV antibody testing was positive. The upper gastrointestinal endoscopy was performed and histopathology and immunohistochemistry revealed BL.

INTERVENTIONS

Highly effective antiretroviral therapy and sixth cycles of chemotherapy were administered, followed by autologous hematopoietic stem cell transplantation.

OUTCOMES

The patient has had tumor-free survival for >6 years with normal CD4+ T cell counts and HIV viral load below the lowest detection LESSONS:: The patient was treated with AHSCT followed complete remission after chemotherapy and achieved long-term disease-free survival. AHSCT may be a promising way for clinical cure of HIV-related BL.

Sporadic Burkitt's lymphoma masquerading as an intussuscepted Meckel's diverticulum in a 9-year-old child

We report the case of a 9-year-old boy who presented with abdominal pain and was found to have an intussusception with a sporadic Burkitt's lymphoma (BL) lead point. Our case was unusual in that the patient did not present with the typical clinical features of BL, nor was he in a high-risk demographic for this uncommon disease.

Gastric Burkitt lymphoma: A case report and literature review

RATIONALE

Burkitt lymphoma (BL) is an endemic tumor in Africa but rare sporadic cases are diagnosed in Europe.

PATIENT CONCERNS

A 60-year-old woman was hospitalized with fulminant hematemesis and a history of recurring melena.

DIAGNOSES

The upper gastrointestinal endoscopy revealed a tumor of the antrum.

INTERVENTIONS

Emergency gastrectomy was performed.

OUTCOMES

Gross findings revealed an ulcerated tumor with elevated margins and several perigastric and extragastric lymph nodes. Histological examination showed proliferation of atypical lymphocytes with a Ki67 index of 100%; they were marked by CD20, CD79a, bcl-6, and CD10 and were negative for CD3, CD5, CD23, TdT, bcl-2, and Cyclin D1. The tumor cells crossed the serosa and presented invasion of the lymph nodes. The patient died 10 days after surgery due to bronchopneumonia and acute renal failure.

LESSONS

In our department, only one gastric BL was diagnosed in a 61 consecutive lymphomas of the gastrointestinal tract (1.64%). Less than 200 reports about gastric-BL have been published to date. This case highlights the difficulty of diagnosis of rare variants of aggressive gastric lymphomas in medium-income countries without screening programmes.

Adult ileocolic intussusception caused by Burkitt lymphoma

Ileocolic intussusception due to Burkitt lymphoma is extremely rare in adults. A man aged 17 years presented with a history of recurrent abdominal pain over the past 3 weeks. The abdomen was distended with diffuse tenderness, and bowel sounds were present. Abdominal ultrasound and CT scans showed evidence of small bowel obstruction with marked wall thickening in the ileocecal region and 'target' signs suggestive for intussusception. At laparoscopy, a mass involving the caecum and the terminal ileum was found, along with multiple locoregional nodes, which was highly suggestive of malignancy. A typical en bloc right colectomy with intracorporeal ileocolic anastomosis was performed. Histopathological examination showed a high-grade B-cell Burkitt lymphoma that was confirmed by immunohistochemistry. The patient was subsequently treated with adjuvant combination chemotherapy and is alive and disease-free at the 3-year follow-up.

HIV-related Burkitt lymphoma with florid granulomatous reaction: an unusual case with good outcome

Burkitt lymphoma (BL) is a highly aggressive subtype of non-Hodgkin lymphomas (NHL). Lymphoma related granulomatous reaction rarely occurs in sporadic BL. Herein, we describe the first case of HIV related Burkitt lymphoma with florid granulomatous reaction. A 41-year-old HIV-positive Chinese male presented lymphadenopathy in the right cervical region for 3 months. The enlarged lymph node biopsies revealed the presence of prominent granulomas of varying size with Langhans giant cells, leading to the misdiagnosis of tuberculous lymphadenitis in other hospital. Subsequently, the case was sent to us for consultation. The morphology, immunophenotype, special staining, interphase FISH analysis and blood tests confirmed a diagnosis of HIV related Burkitt lymphoma with granulomatous reaction. Without radiotherapy and chemotherapy, the patient was alive and well with no evidence of lymphoma during the observation period of 24 months. The case suggested that lymphoma with florid granulomatous reaction can easily be misdiagnosed as benign lesions since the large number of epithelioid granulomas could obscure the primary lesion. Moreover, the granulomatous reaction may be an indicator for favorable prognosis in HIV related Burkitt lymphoma.

[Burkitt's lymphoma presenting as ovarian tumor]

Burkitt's lymphoma is a rapidly progressing tumor, which could be cured in 60-80% of cases. Its infiltration of the ileo-cecal region often spreads to the ovaries, though primary ovarian manifestation is also common. By presenting our case of a 27-year-old nulliparous patient with primary ovarian Burkitt's lymphoma, we would like to draw attention to its diagnostic and therapeutic difficulties.

[Therapeutics of Burkitt lymphoma in adults - review]

Burkitt lymphoma is a highly aggressive non-Hodgkin's lymphoma. As Burkitt lymphoma cells are very sensitive to chemotherapy, chemotherapy is the major therapeutic schedule for this disease. Rituximab raised the overall survival rate markedly. Bone marrow transplant, surgery and radiotherapy also demonstrated to have a supporting role for patients with Burkitt lymphoma. This review focus on research progress of the therapeutics and major regimens for the disease.

Burkitt lymphoma in a child with atopic dermatitis and a 7-year history of regular topical tacrolimus use

We describe the case of a boy who presented with abdominal Burkitt lymphoma; he had been regularly using tacrolimus ointment 0.1% for severe recurrent atopic dermatitis for 7 years immediately prior to developing cancer. We present his medical history and review the current knowledge regarding a link between topical tacrolimus and malignancy risk.

Burkitt-like lymphoma infiltrating a hyperfunctioning thyroid adenoma and presenting as a hot nodule

BACKGROUND

Most solitary hyperfunctiong regions on thyroid scan consist of benign tissue. Here we report a patient with a Burkitt-like lymphoma that was infilterated into a region containing a hyperfunctioning nodule.

SUMMARY

A 56-year-old man was referred to our Endocrine Unit in May 2009 due to the incidental discovery of a large left thyroid lobe nodule by a computed tomography study. This had been performed to search for a primitive tumor in a patient with bone metastasis. He was clinically and biochemically thyrotoxic with no evidence of humoral thyroid autoimmunity. The nodule had a dyshomogenous appearance at neck ultrasonography, with multiple hypoechogenic areas and calcifications. (99m)-Technetium thyroid scintiscan revealed a hot nodule with suppression of the contralateral lobe. Fine-needle aspiration cytology indicated the presence of neoplastic cells not of thyroid origin. Remission of hyperthyroidism was obtained with methimazole, and the patient was submitted to left lobe thyroidectomy and istmectomy. Histological analysis of the surgical specimen led to a diagnosis of Burkitt-like large B-cell lymphoma harbored within a thyroid adenoma. After further staging, the final diagnosis was stage IV E Burkitt-like lymphoma with the involvement of the bone and the thyroid. This is the first description of an aggressive Burkitt-like lymphoma that infiltrated an hyperfunctioning thyroid adenoma, thus presenting as a hot nodule at thyroid scintiscan. In our patient there was no humoral or histological evidence of thyroid autoimmunity, thus suggesting a metastatic seeding of the lymphoma within the hyperfunctioning thyroid nodule.

CONCLUSIONS

Involvement of the thyroid gland by Burkitt-like lymphoma is extremely rare as is close localization of malignancy and a hyperfunctioning thyroid nodule. As highlighted by the present report, performing fine-needle aspiration cytology should be always considered in the clinical context of a metastatic disease of unknown origin or when there are ultrasonography signs suggesting malignancy, even when the nodule is hyperfunctioning.

[Malignant primary cardiac tumors in childhood and adolescence]

Primary heart tumors are uncommon in children. The majority of them are benign, with only 10% malignant. Among malignant cardiac tumors, sarcoma (rhabdomyosarcoma, angiosarcoma, synovial sarcoma) and lymphoma (Burkitt's lymphoma, large B-cell lymphoma, lymphoblastic lymphoma) predominate. There are few published pediatric series on malignant primary cardiac tumors. We report here 3 observations of primary malignant cardiac tumors, 2 cases of sarcoma (angiosarcoma and synovial sarcoma) and 1 case of Burkitt's lymphoma. A precise pathological diagnosis is necessary for the proper management of these patients. For sarcoma, treatment associates surgery and chemotherapy. Surgery should be as complete as possible because of the lack of chemotherapy sensitivity of some sarcomas, mainly angiosarcoma and synovial sarcoma. Therefore, the prognosis of cardiac sarcoma remains poor. For primary cardiac lymphoma, management should not be different from lymphoma in other locations. Chemotherapy is the main treatment, and surgery has to be used only when complications occur. Prognosis depends on histology and not lymphoma location, and so is better than the prognosis for sarcoma.

A rare case of ovarian Burkitt lymphoma associated tumor lysis syndrome

A 21-year-old woman who presented with pelvic mass, fever and cough was admitted. Ultrasonography revealed a large solid mass and serum CA125 was increased. A bilateral salpingo-oophorectomy was performed and pathological diagnosis showed Burkitt lymphoma of bilateral ovaries. Adjuvant chemotherapy was administrated after surgery. However, on the next day, the patient had an unexpectedly high fever, sigh-like breathing, dilated pupils, and died despite rescue. This is the first report on the post-treatment tumor lysis syndrome with ovarian Burkitt's lymphoma. Identifying patients at risk and initiating therapy early are essential to avoid serious complications associated with tumor lysis syndrome.

Primary cardiac Burkitt-like lymphoma of the right atrium

A 74-year-old man presented for shortness of breath. Echocardiography revealed the presence of a large pericardial effusion with signs of tamponade. A right atrial mass was suspected and later confirmed by transesophageal echocardiography. The mass was attached to the right side of the interatrial septum. Surgical resection was performed. Histology was compatible with a diagnosis of undifferentiated B-cell non-Hodgkin's (Burkittlike) primary cardiac lymphoma. The present report provides the first description of a Burkitt-like primary cardiac lymphoma. The presence of a mass in the right atria should raise the possibility of a malignant cardiac tumour. Transesophageal echocardiography should be considered as the initial diagnostic procedure to be performed. Rapid histological diagnosis is important because systemic therapy can influence prognosis in the presence of a primary cardiac lymphoma.

[Burkitt's lymphoma of the caecum in a patient with AIDS: clinical case and review of the literature]

Overall, lymphomas of the gastrointestinal tract are rare, although they are the most frequent extranodal location. The incidence of primary colic lymphoma, above all in the non-Hodgkin variant, is clearly higher in the HIV positive population, especially in subjects with AIDS. The authors present the case of a 51-year-old patient with AIDS undergoing antiviral therapy; he was suffering from abdominal pain and presented a palpable mass in the right iliac fossa; diagnosis was caecal non-Hodgkin lymphoma (NHL); radical right hemicolectomy was carried out with definitive histological diagnosis of Burkitt-type small cell NHL. The NHL of the colon represents no more than 1.2% of all malignant cancers of this part of the intestinal tract. Nevertheless such cases are comparatively frequent in patients with HIV virus, especially in the active phase and clinically proven to be due to immunodeficient syndrome. Of cardinal importance is the differential diagnosis between primary and secondary forms because of the different treatment and prognosis. Frequently such forms are observed in patients with AIDS, at advanced stages and with differentiated and hence more aggressive histotypes, also because they are present in organisms weakened by the underlying disease and by immunodeficiency. Primary NHLs of the colon are relatively frequent and aggressive in patients with AIDS; early diagnosis and treatment are therefore of fundamental importance to improve the oncological outcome for these patients.

Adult Burkitt lymphoma: advances in diagnosis and treatment

Burkitt lymphoma is a unique B-cell malignancy with a high proliferation rate and characteristic genetic changes involving the c-myc oncogene. Burkitt lymphoma is common in children but also occurs in adults, where distinction from diffuse large B-cell lymphoma may pose a problem. The development of brief, very intensive chemotherapy regimens has led to a very high cure rate in children with Burkitt lymphoma. The use of these regimens in adults, often in combination with the antibody rituximab (Rituxan), has also made the cure of a majority of adults possible. Burkitt lymphoma in adults cannot be treated effectively with the common regimens used for diffuse large B-cell lymphoma such as CHOP-R (cyclophosphamide, doxorubicin HCl, vincristine [Oncovin], prednisone, rituximab). Prompt diagnosis and initiation of appropriate therapy with attention to the possibility of tumor lysis syndrome are necessary for optimal results.

[Abdominal Burkitt lymphoma mimicking the ovarian cancer. Case report and review of the literature]

Primary Burkitt lymphoma is a lymphoblastic B-cell malignant tumor with very aggressive course. Its abdominal form involving internal genital organs is very rare.

CASE

We report the case of 27-year-old woman treated for abdominal Burkitt lymphoma. The patient presented bilateral ovarian tumors with ascites, pain and elevated CA 125 over 900 IU/ml. During laparotomy an advanced neoplasmatic disease involving internal genital organs has been diagnosed. Bilateral salphingo-oophorectomy and omentectomy have been performed. Additionally, the neoplasmatic tumor from ileo-coecal region has been ressected in order to prevent ileus. Pathologic examination has revealed an abdominal Burkitt lymphoma. After surgery, polychemotherapy has been administered (COP followed by CODOX-M+IVAC). The patient, 36 months after surgical treatment, remains under the control of our Department. No signs of recurrence have been detected so far.

CONCLUSIONS

The presence of primary abdominal Burkitt lymphoma may include clinical and laboratory findings suggesting the presence of ovarian cancer. Chemotherapy appears to be an essential therapeutic management for all forms of Burkitt lymphoma. Clinically advanced Burkitt lymphoma may be successfully managed with chemotherapy.

Clinical implications and surgical management of intussusception in pediatric patients with Burkitt lymphoma

BACKGROUND/PURPOSE

Intussusception as a presenting feature of Burkitt lymphoma may be associated with early stage disease, which is curable with less intensive therapy. We determined the incidence, presentation, stage, and outcome of children with Burkitt lymphoma presenting with intussusception.

METHODS

The medical records of patients with Burkitt lymphoma treated at our hospital from 1962 to 2005 were reviewed, and the patients presenting with intussusception were then further analyzed.

RESULTS

Of 189 patients with primary abdominal Burkitt lymphoma, 33 (17.5%) presented with intussusception. Their median age at diagnosis was 10 years (range, 3-19 years). Most patients presented with abdominal pain (88%) and/or nausea/vomiting (42%). Twenty-three (70%) of these 33 patients as compared with 10 of the other 156 patients with abdominal lymphoma could have complete resection of their tumor (P < .0001) and hence had low stage disease (stage II). Only 10 patients with intussusception had stage III (n = 7) or stage IV (n = 3) unresectable disease. Twenty-five of the patients remained alive in continuous complete remission for 3 months to 31 years (median, 14 years).

CONCLUSION

Pediatric patients with Burkitt lymphoma presenting with intussusception often have completely resectable disease and are older than general pediatric patients with intussusception.

Burkitt's lymphoma of the base of the tongue: a case report and review of the literature

Burkitt's lymphoma is a highly aggressive, mature B cell non-Hodgkin's lymphoma that is rare outside Africa. We report a case of Burkitt's lymphoma presenting as a rapidly expanding tongue-base mass that caused airway obstruction in an 80-year-old Palestinian man living in California. According to our review of the literature, this is only the third reported case of Burkitt's lymphoma arising in the base of the tongue. We also discuss the incidence, epidemiology, genetics, prognosis, and treatment of this malignancy. Because Burkitt's lymphoma is one of the fastest-growing tumors in humans, rapid diagnosis and treatment are important. Treatment involves brief-duration, high-intensity chemotherapy and central nervous system prophylaxis. It is important for the otolaryngologist to recognize this disease and to understand the steps necessary to treat this aggressive tumor.

A case of primary unilateral adrenal Burkitt-like large cell lymphoma presenting as adrenal insufficiency

Primary adrenal lymphoma is extraordinarily rare, in comparison with secondary adrenal involvement by non-Hodgkin lymphoma. Although higher-resolution imaging techniques have enhanced detection of adrenal masses, biopsy or excision is often needed for definitive diagnosis. Percutaneous computed tomography-guided fine needle aspiration has great diagnostic value in the workup of adrenal masses, but is limited by sampling error and artifacts. Primary adrenal lymphoma most commonly manifests with diffuse large B-cell morphology. Burkitt-like large cell lymphoma morphology has been previously reported only once, to our knowledge. We report an 80-year-old man presenting with unilateral primary adrenal lymphoma showing Burkitt-like morphology and adrenal insufficiency. Fine needle aspiration yielded a dispersed population of monomorphic, medium to large cells suggestive of lymphoma. Although dispersed cell populations cytologically favor lymphoma, metastatic poorly differentiated carcinoma and adrenal cortical carcinoma can manifest similarly. Integrated histological, immunohistochemical, and flow cytometric immunophenotyping would provide an accurate and definitive diagnosis. We review the literature and discuss important issues with regard to diagnosis.

Burkitt'S lymphoma mimicking a primary gynecologic tumor

OBJECTIVE

Burkitt's lymphoma (BL) occurs mostly in children; bilateral ovarian involvement mimicking a gynecologic malignancy in adults is extremely rare. Here, we report a patient with BL mimicking a gynecologic tumor.

CASE REPORT

A 50-year-old Taiwanese woman presented with the complaint of persistent lower abdominal distension with dull pain, easy satiety, and progressively increasing abdominal girth for 2 weeks. Amenorrhea was also noted for about 2 months, and her review of systems was negative for the common "B" symptoms associated with lymphoma. At our hospital, imaging studies revealed a huge pelvic mass (10.8 x 8.7 cm), suggesting a large subserous myoma or an ovarian tumor. Under the impression of pelvic mass, she underwent exploratory laparotomy. Primary ovarian sex-cord malignancy with cecum involvement was impressed by the primitive intraoperative frozen section report. Subsequently, an optimal cytoreductive operation with right hemicolectomy was performed. However, final histopathologic report was an extranodal multifocal BL.

CONCLUSION

Although extranodal BL in ovaries is a rare condition, it should be noted in the differential diagnosis of pelvic gynecologic malignancies.

Intra-cardiac Burkitt's lymphoma mimicking acute pulmonary embolism

Primary cardiac lymphoma is a rare clinical entity with poor prognosis and delayed diagnosis is often due to variable and non-specific clinical presentation. The case of an elderly male is reported with multiple co-morbidities, who had undergone a spinal laminectomy two weeks prior to presentation, later presented to the emergency room (E.R.) with acute chest pain, dyspnea and hypoxemia. A diagnosis of intracardiac thrombus was made, based on the clinical picture and echocardiography findings but per-operatively, he was found to have an extensive, non-resectable cardiac tumor.

The evolving management of Burkitt's lymphoma at Red Cross Children's Hospital

BACKGROUND

Treatment for Burkitt's lymphoma at Red Cross Children's Hospital has evolved from the use of aggressive surgery and less intensive chemotherapy to a conservative surgical approach with more intensive chemotherapy.

METHODS

The study was a retrospective folder review of patients diagnosed with Burkitt's lymphoma at RCCH between 1984 and 2004.

RESULTS

Ninety-two children were treated for Burkitt's lymphoma at RCCH between 1984 and 2004. There were 10 patients with group A or fully resected disease, 52 with group B or extensive localised disease, and 30 with dissemination to the bone marrow and/or central nervous system or group C disease. Protocol 1 (less intensive chemotherapy based on the COMP regimen) was used from 1984, with protocol 2 (more intensive chemotherapy based on the LMB regimen) introduced in 1988 for group C disease, 1991 for group B disease and 1996 for group A disease. Overall 5-year survival increased from 20% with protocol 1 to 66% with protocol 2 for group C disease, and from 76.5% with protocol 1 to 88.2% with protocol 2 for group B disease. There were more admissions for neutropenic fever in patients on protocol 2 and more episodes of mucositis, and these patients required more red cell and platelet transfusions. With a more conservative surgical approach, biopsy largely replaced attempts to partially resect the tumour at primary surgery, and there was a consequent decline in surgical complications.

CONCLUSIONS

Intensive chemotherapy with protocol 2 has resulted in improved survival for group C and group B patients, but with more morbidity. Protocol 1, which is less intensive with less morbidity, remains a viable strategy for group A and group B disease in resource-poor settings.

Burkitt’s Lymphoma of the Ovary in Pregnancy

BACKGROUND

Burkitt's lymphoma is a rapidly growing and, if untreated, rapidly fatal tumor derived from B-lymphocytes. The occurrence of Burkitt's lymphoma during pregnancy is rare.

CASE

A patient with Burkitt's lymphoma presented at 12 weeks of gestation with abdominal and tooth pain. An 11 x 11 x 15 cm mass was seen on abdominal/pelvic ultrasonogram. She underwent a left salpingo-oophorectomy with removal of the mass, as well as a tooth extraction. The pathology examination confirmed lymphoma in the left ovary and in the tissue surrounding the extracted tooth. After surgical resection, she was treated with multiagent chemotherapy beginning at 13 4/7 weeks of gestation. At 39 weeks, she delivered a viable female infant weighing 2,270 g.

CONCLUSION

The finding of an adnexal mass in conjunction with head and neck symptoms led to consideration of Burkitt's lymphoma. Prompt treatment with multiagent chemotherapy should be considered for pregnant patients with Burkitt's lymphoma.

Primary meningeal Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome

The purpose of this study is to report a rare case of primary meningeal high grade Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome. A 38-year-old Caucasian man, with a negative past medical history, sought treatment after experiencing global headache for five days. CT-Scan revealed a right front-temporo-parietal hyperdense subdural expansive mass. A craniotomy was performed and a hard white subdural was microsurgically dissected. Some hours after the surgery, the patient developed hemispheric cerebral edema and intracranial hypertension syndrome. Decompressive craniotomy was performed and the patient had an excellent recovery. Screening blood tests diagnosed human immunodeficiency virus infection. Further investigation ruled out systemic diseases. Eleven days after the initial surgery, the patient developed an acute respiratory failure and sepsis, dying on that day. Pathological studies diagnosed Burkitt-type lymphoma.

Primary Burkitt lymphoma of the ovary

A 20 year-old woman presented with features of a twisted ovarian cyst and had an emergency laparotomy Intraoperative findings revealed bilateral, solid ovarian tumors and a left oophorectomy with biopsy of the contralateral ovary performed. Histopathology report confirmed Burkitt lymphoma of ovary. There was no other evidence of lymphoma elsewhere. The primary Burkitt lymphoma of the ovaries was successfully managed with six courses of highly toxic chemotherapy (Berlin-Frankfurt- Munster 1986 protocol). The patient has remained disease free for the last 36 months.

[An abdominal Burkitt's lymphoma in acute phase. Case report]

Burkitt's lymphoma is a highly malignant, aggressive and rapidly growing B-cell neoplasm, which has low long-term survival rates. Abdomen is the most frequent onset site of nonendemic Burkitt's lymphoma. The rapidity of volumetric doubling of this neoplasm frequently justifies an abdominal acute presentation, that may mime other less rare diseases. Symptoms are often misleading and make diagnosis difficult. The aim of this work is to report a case of a 13-year-old boy affected by terminal ileum Burkitt's lymphoma with hepatic metastasis, which initially was mistaken for acute appendicitis complicated by hepatic abscesses and, following a second surgical operation, for terminal-ileum inflammatory bowel disease. The rapidity of growth of this neoplasm justifies the finding, during the second surgical operation, of a mass that was not clinically manifested during first operation, carried out only a week ago. Clinical signs and instrumental investigations were not diagnostic, as well as the literature reports. The role of surgery remains controversial, and is usually limited to collection of specimens for histological diagnosis or to management of acute complications, as in our case report. Mostly treatment protocols are based on chemotherapy, because of the high sensibility of this neoplasm.

The impact of acute and chronic graft-versus-host disease on normal and malignant B-lymphoid precursors after allogeneic stem cell transplantation for B-lineage acute lymphoblastic leukemia

BACKGROUND AND OBJECTIVES

The development of graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT) for B-lineage acute lymphoblastic leukemia (B-ALL) is associated with a lower probability of leukemia relapse. However, mechanisms by which this GVHD-associated graft-versus-leukemia effect is exerted are poorly understood. In this study, we simultaneously traced the kinetics of normal donor-derived and leukemic recipient-derived B-lymphopoiesis comparing patients with or without GVHD.

DESIGN AND METHODS

We used multiparameter flow-cytometry to quantify pro-B (CD19+CD10+CD34+), pre-B (CD19+CD10+CD34-) precursors and malignant lymphoblasts identified by leukemia-associated markers in 161 prospective marrow samples from 39 consecutive B-ALL patients after allogeneic SCT. Chimerism analysis was performed by quantitative real-time polymerase chain reaction of null alleles and insertion/deletion (indel) polymorphisms.

RESULTS

Acute GVHD of grades II-IV is associated with a strong inhibition of normal donor-derived pro-B and pre-B precursors at days +30 and +60 post-SCT. Patients who develop chronic GVHD have lower percentages of marrow B-cell precursors during the first year after SCT. Likewise, recipient-derived leukemia B cells were absent at days +30 and +60 in patients with acute GVHD grades II-IV and were less likely to be detected in patients with chronic GVHD. Induction of GVHD as treatment of increasing amounts of leukemia cells causes inhibition of both normal and malignant B compartments even in the absence of steroid therapy.

INTERPRETATION AND CONCLUSIONS

We conclude that the development of GVHD after allogeneic SCT is associated with a non-specific inhibition of B-lymphopoiesis.

Life-threatening airway obstruction secondary to mass in children-a preventable event?

OBJECTIVES

To investigate the management of children with life-threatening airway obstruction from large mediastinal masses.

METHODS

Review of the medical records of children with mediastinal masses and severe airway obstruction who were admitted to a multidisciplinary pediatric intensive care unit.

RESULTS

Eight patients with 12 life-threatening events were identified. Five events (in 4 patients) occurred before hospital admission, and 3 patients had more than 1 choking episode. Five patients underwent cardiorespiratory resuscitation (2 before admission), and 2 underwent emergency endotracheal intubation because of severe airway obstruction; the eighth patient could not be weaned off the ventilator until the mediastinal mass was resected. Median time from appearance of the initial symptoms to diagnosis was 8.5 days, and median time from the onset of alarming signs to admission was 2 days.

CONCLUSIONS

Severe airway obstruction in children with an anterior mediastinal mass is not rare and can lead to complete obstruction, requiring cardiorespiratory resuscitation. Physician awareness and preparedness for respiratory complications are essential for proper management of children with mediastinal masses.

Total spinal anesthesia during combined general-epidural anesthesia in a 7-year-old child

Total spinal anesthesia (TSA) is a rare complication of lumbar epidural anesthesia through inadvertent spinal injection of local anesthetics following an undiagnosed dural breach or spinal placement of the catheter. TSA has rarely been reported in children. TSA occurred during epidural anesthesia in a 7-year-old child undergoing abdominal surgery. Recent previous lumbar punctures and intrathecal chemotherapy for Burkitt's lymphoma at the same level may have facilitated dural breach. Epidural anesthesia should not be attempted at the same intervertebral level as prior recent lumbar punctures.

Pediatric tumors of the parapharyngeal space. Three case reports and a literature review

Three cases of pediatric primary parapharyngeal space tumors, namely a Burkitt's lymphoma, lipoblastoma and a ganglioneuroma are described here, along with a literature review. These disorders are very rare, accounting for less than 20% of all parapharyngeal neoplasms. In comparison to adults, there are differences in pathomorphologic spectrum of pediatric parapharyngeal tumors. The authors describe the prevalence of malignant tumors, mainly soft tissues sarcomas. The salivary gland tumors and paragangliomas which dominate in adult populations, are extremely rare in pediatric populations where the most common benign tumor to be encountered is that of neurogenic origin. It follows that these features modify the diagnostic and therapeutic approach.

Extensive peritoneal and omental lymphomatosis with raised CA 125 mimicking carcinomatosis: CT and intraoperative findings

Diffuse peritoneal and omental seeding are well-known forms of dissemination of metastatic carcinoma. A wide variety of primary neoplasms may cause peritoneal and omental carcinomatosis, most commonly carcinomas of the ovary, gastrointestinal tract and breast. Extensive involvement of the peritoneal cavity with lymphoma is, however, rare. The association of peritoneal lymphoma with a raised CA 125, a tumour marker which is commonly raised in ovarian carcinoma, is a highly challenging clinical situation, which to our knowledge has not been published before in the medical literature. Not being aware of the possibility of this unusual combination of clinical, laboratory and imaging findings can lead to an erroneous diagnosis, as in our case.

Interdisciplinary approach to abdominal Burkitt's lymphoma

Burkitt's lymphoma is a high-grade, rapidly growing B-cell neoplasm. It is recognized by its aggressive course, brief median survival, and low rates of long-term survival. The authors discuss the case of a patient who acutely presented with intraabdominal complications from a new onset of Burkitt's lymphoma. The clinical and pathological features, staging, treatment options, and survival data are reviewed. In addition, the role of surgical intervention is carefully analyzed.

The role of surgery in intraabdominal Burkitt's lymphoma in children

The role of surgery in intraabdominal Burkitt's lymphoma remains controversial and different opinions are present in the literature. In our institution, forty patients (30 boys and 10 girls) with intraabdominal Burkitt's lymphoma with ages ranging from 3 to 12 years have been treated and followed from 1989 through 2000. In ten cases, the patients underwent surgery because of their acute abdominal diseases (intestinal obstruction in 5, intussusception in 3, intestinal perforation in one, and acute appendicitis in one). The remaining thirty patients were referred to our clinic because of their abdominal masses, pain, anorexia and fatigue. Twelve children had localized tumors and total resection could be performed. There was one death in this group due to central nervous system involvement during chemotherapy. In the remaining 28 children, extensive intraabdominal diseases were detected. In four of them, debulking procedures were performed, while in 24 children only biopsies could be made; 8 of them underwent a second-look operation. In the debulking procedures group, two children were lost (50 %) due to tumorlysis and acute renal failure. In the biopsy group, there were six deaths (25 %). All patients received chemotherapy after operative recovery. In conclusion, our results suggest that when the tumor is localized, total resection results in a good outcome. However, in the presence of extensive intraabdominal diseases instead of resection, the operation should be limited to biopsy only.

[Burkitt lymphoma involving the ovaries]

Burkitt lymphoma is a very rare type of lymphoma with a predilection for the ovary. We report a case of 18-years old woman with dramatic course of the Burkitt lymphoma involving ovaries. Immunohistochemistry techniques allowed for the diagnosis and the successful chemotherapy. The case demonstrates the importance of an appropriate pathology evaluation and interdisciplinary collaboration.

High survival rate in childhood non-Hodgkin lymphoma without CNS involvement: results of BFM 95 study in Kuwait

Non-Hodgkin lymphomas (NHL) in children are the second most common malignant tumors in Kuwait. Until 1995 the patients (pts) received institutional protocols. From October 1995 to September 2000 21 children with NHL were treated. Five children were treated by NHL BFM 90 protocol, 7 pts received NHL BFM 95 scheme, and 9 children underwent therapy abroad or according to different types of protocols. The results of a retrospective analysis of NHL BFM 95 protocol in Kuwait are reported. Seven patients diagnosed with NHL--group B: 3 children with Burkitt lymphoma (B-cell NHL) and group A: 4 children with lymphoblastic lymphoma (T-cell NHL)--were treated from October 1995 to September 2000 in the Kuwait Cancer Control Centre according to NHL BFM 95 protocol. Group B consisted of 2 girls and 1 boy; median age at diagnosis was 4 years 8 months, 2 pts classified as stage II and 1 pt as stage III. All patients were assigned to risk group R2. Median follow-up is 2 years 8 months. Group A included 1 girl and 3 boys; median age at diagnosis was 5 years 8 months, 1 pt classified as stage III and 3 pts as stage IV. All patients were assigned to IR group. Median follow-up is 3 years 6 months. In group B all 3 pts are in 1st CR; in group A 3 pts are in 1st CR and 1 pt having Li-Fraumani syndrome died after the 3rd relapse of disease during therapy. In both groups there was no toxic death, myelotoxicity WHO grade III-IV, hepatotoxicity WHO grade II-III. Treatment results of NHL BFM 95 study in our small group of patients are very optimistic. Six patients are in 1st CR and one died due to progression of disease. Despite the small group of patients, the results suggest that NHL BFM 95 protocol is highly effective and safe with regular supportive care.
