Primary diffuse large B-cell lymphoma of the ascending colon

Comparison of clinical features of patients with or without severe gastrointestinal complications in aggressive gastrointestinal lymphomas

BACKGROUND

Aggressive primary gastrointestinal non-Hodgkin lymphoma (PGINHL) is an uncommon and heterogeneous group of lymphoid malignancies, that differs from indolent lymphoma and has a high incidence of severe gastrointestinal complications (GICs).

AIM

To investigate and compare the clinicopathological characteristics, treatments and outcomes in the GICs and No-GICs group with aggressive PGINHL.

METHODS

This retrospective analysis was performed on aggressive PGINHL patients between January 2013 and December 2021 at our hospital. The independent influence factors of GICs were obtained by univariate and multivariate Logistic regression analysis, the selected variables significantly related to GICs were selected as the final predictors to construct nomogram. Kaplan-Meier curves further analyzed the survival of patients in GICs and No-GICs groups. Survival analysis of GICs group was performed using Cox regression.

RESULTS

We focused on 124 aggressive PGINHL cases, which had a relatively high incidence 48.4% (60/124 cases) of GICs, the most common histological type in GICs group was diffuse large B-cell lymphoma (DLBCL) (n = 49, 81.7%). In the GICs group, small intestine was the most common anatomic site of lesion (43.3%), followed by large intestine (31.7%), and then stomach and esophagus (25.0%). Multivariate Logistic regression analysis showed that the independent risk factors for GICs were the small intestine [odd ratio (OR) = 3.33; 95% confidence interval (CI): 1.47-9.41; P = 0.009), aggressive B-cell (OR = 0.09; 95%CI: 0.01-0.83; P = 0.033), maximum tumor diameter (OR = 1.25; 95%CI: 1.07-1.47; P = 0.005), invaded deep serous layer (OR = 3.38; 95%CI: 1.24-9.19; P = 0.017). We developed a nomogram to predict risk of GICs in aggressive PGINHL patients based on independent risk factors. The value of area under curve calculated by receiver operating characteristic curve was 0.815, and calibration curve and decision curve analysis further indicated that the prediction effect was superior. The majority of patients with GICs were given combination therapy (chemotherapy combined with surgery or radiation). Event-free survival and overall survival in GICs group were no worse than those in the No-GICs group.

CONCLUSION

The complication rate of GICs in patients with aggressive PGINHL was relatively high, particularly in PGI-DLBCL. The independent risk factors for GICs were the small intestine, PGI-TNKL, bulky tumor, and depth of invasion. A combination treatment, involving surgery, improved survival in the GICs group.

Distal Ileitis Caused by Diffuse Large B-Cell Lymphoma in an Elderly Patient From Honduras

Primary gastrointestinal non-Hodgkin lymphoma, while rare, most often presents as diffuse large B-cell lymphoma located in the stomach or ileocecal region. Presenting symptoms include abdominal pain, gastrointestinal bleeding, weight loss, or obstructive symptoms. Imaging can reveal ileitis or obstruction. We report a case of a man from Honduras with latent tuberculosis and chronic hepatitis B who presented with features of Crohn's disease through clinical, radiologic, and endoscopic findings but was ultimately diagnosed with diffuse large B-cell lymphoma by histology. We emphasize the importance of maintaining a broad differential for ileitis and the importance of histologic sampling when evaluating ileitis.

Primary colon lymphomas: An analysis of our experience over the last 18 years

Colon lymphoma is a rare type of gastrointestinal lymphoma and represents 0.2% to -1.2% of all primary colon cancers. This study aimed to retrospectively examine the general characteristics, treatment methods, and survival characteristics of patients with colon lymphoma who were followed-up at our center. This retrospective study included patients diagnosed with colon lymphoma who were followed up at Ankara Numune Training and Research Hospital and Ankara Bilkent City Hospital between December 2005 and June 2023. Clinicopathological features, radiological findings, treatments, and modalities of patients were obtained from their medical records. Fourteen patients with primary colon lymphoma were included in the study. Thirteen patients (92.9%) were diagnosed with diffuse large B-cell lymphoma. The median age of the patients was 55 (28-84) years. The tumor location was the terminal ileum/cecum in 50% of the patients. At the time of diagnosis, 10 patients (7 with stage 1E-2E disease, 2 with stage 3E disease, and 1 with stage 4E disease due to tumor obstruction) underwent surgery. Twelve patients received chemotherapy (6 patients as adjuvant and 6 patients as first-line treatment). The median overall survival (OS) was 10 years (0.1-21.5) years, the 5-year median OS was 71%, and the 10-year median OS was 53%. Primary colon lymphoma is a rare disease and its optimal treatment is not clearly defined. The primary treatment for primary colon lymphoma is a combination of surgery and chemotherapy. A clear consensus on the treatment can be established through prospective studies.

Primary diffuse large B-cell lymphoma of the cecum

When found in the cecum or rectosigmoid junction, primary colorectal B-cell lymphoma is a rare malignant non-Hodgkin's lymphoma often associated with an unfavorable prognosis. Due to the nonspecific clinical symptoms, these uncommon tumors are often left undefined or misdiagnosed, resulting in delays in treatment and adverse patient outcomes. Contrast-enhanced computed tomography is the most commonly used medical imaging process for primary colorectal lymphoma, but due to the rarity of this disorder, accurate imaging diagnosis remains a clinical challenge. In this article, we report the case of a 70-year-old male who was diagnosed with primary B-cell lymphoma of the cecum. We focus on improving diagnosis through the utilization of radiological imaging modalities, particularly computed tomography (CT) and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18-F-FDG PET/CT). While imaging modalities are important in recognizing colonic lymphomas, there are no pathognomonic imaging features for lymphoma; therefore, biopsy remains necessary for diagnostic confirmation.

Unusual Instance of Primary Diffuse Large B-cell Lymphoma of the Colon

Diffuse large B-cell lymphoma (DLBCL) commonly affects the gastrointestinal (GI) tract, although primary DLBCL rarely occurs in the colon. Primary colorectal lymphoma is a surprisingly rare diagnosis, accounting for a minute percentage of GI lymphomas and colorectal malignancies. We present an interesting case of an immunocompromised young adult female who was diagnosed with DLBCL confined to a cecum polyp after she underwent a colonoscopy for a GI bleed. The lymphoma presented endoscopically as a semi-sessile polyp in the cecum that was successfully removed. The patient was treated with appropriate therapy of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).

Diffuse Large B-Cell Lymphoma of the Cecum

Lymphoma when arising from sites other than lymph nodes is termed extranodal lymphoma, commonly affecting the gastrointestinal tract. Primary colorectal lymphoma is a rare phenomenon among malignancies affecting the colon. We report a case of a patient with a history of Burkitt lymphoma in remission, presenting with a large cecal mass and a new diagnosis of diffuse large B-cell lymphoma treated with chemotherapy.

Endoscopic features of colorectal lymphoma according to histological type

Background and Aim

This study aimed to investigate the relationship between the histological type of colorectal lymphoma and its endoscopic features.

Methods

We retrospectively analyzed patients with primary colorectal lymphoma who were diagnosed using colonoscopy and biopsy specimens at the National Cancer Center Hospital, Tokyo, Japan. The lesions were macroscopically classified into the following types via colonoscopy: polypoid, ulcerative, multiple lymphomatous polyposis, diffuse, and mixed.

Results

A total of 117 lesions were identified in 90 patients enrolled in this study. Of these, 59 (50%) were located in the ileocecal region, 23 (20%) in the rectum, 9 (8%) in the transverse colon, 8 (7%) in the sigmoid colon, 7 (6%) in the descending colon, and 4 (3%) in the ascending colon. Moreover, the most common histological subtypes were diffuse large B‐cell lymphoma (DLBCL) in 39 patients (43%) and mantle cell lymphoma (MCL) in 23 patients (26%), followed by follicular lymphoma (FL; 17%), mucosa‐associated lymphoid tissue (MALT) lymphoma (9%), peripheral T‐cell lymphoma‐NOS (2%), monomorphic epitheliotropic intestinal T‐cell lymphoma (MEITL; 2%), and Burkitt lymphoma (1%). More than half of the DLBCL (52%), MCL (52%), and MALT (56%) lymphomas were macroscopically classified as polypoid types. In contrast, FL lesions showed various macroscopic types. The majority of DLBCL (62%) and FL (78%) lesions were distributed in the ileocecal region. MCL lesions tended to be widely spread in various sites of the large intestine.

Conclusions

Colorectal lymphomas showed macroscopically distinctive features depending on the histological type. Understanding the macroscopic classification of the lesions by colonoscopy and its distribution may be helpful in diagnosing the type of lymphoma and determining the malignant grade based on the histological types.

A rare case of primary non-metastatic Non-Hodgkin's diffuse large B-cell lymphoma in the ileum in a 19-year-old male manifested as intestinal obstruction- A case report

Introduction and importance

The gastrointestinal system is the most common site for extra-nodal NHL. Adolescent population are among the rarest of compromised groups, especially males. The gastrointestinal system is more involved by secondary metastasis rather than by primary lymphomas. Cardinal B-Symptoms and obstipation constituted the presentation of our patient who was diagnosed postoperatively as a case primary non-metastatic NHL. NHL can have misleading presentations which result in the implementation of different treatment modalities. We ought to have high clinical suspicion when presented with a patient suffering from B-Symptoms and obstipation to make timely judgements which help in performing effective therapeutic interventions to limit the morbidity and mortality which result from this pathology.

Case presentation

We present the case of a 19-year-old male, who presented with obstipation and B-Symptoms. CT scan indicated loop dilation, a lobulated mass, and what radiologically seemed to be intussusception. Surgery was done and the resected specimens were DLBCL.

Clinical discussion

We treated him by surgical excision of the affected ileal segments. Histopathology indicated a primary Non-Hodgkin's DLBCL of the ileum. Afterwards, we referred him for adjuvant chemotherapy. Treatment modalities for this malignancy are mainly surgical in addition to Chemotherapy.

Conclusion

Intestinal extranodal NHL presents with an array of vague symptoms. As a result, this type of tumors can be clinically indistinguishable from other gastrointestinal malignancies. It is vital to keep this type of malignancy in mind as a differential diagnosis when presented with a surgical abdomen in a patient with B-Symptoms.

•

The gastrointestinal system is the most common occurrence site for extra-nodal Non-Hodgkin's Lymphoma.

•

Cardinal B-Symptoms can mislead the diagnosis as the incidence rate in such a patient demographic is undocumented.

•

The most frequently compromised site in the small intestine is the ileum followed by the jejunum, and the duodenum.

•

Primary non-metastatic NH-DLBCL is so rare in adolescent males that it warrants documentation and follow-up.

•

It's vital to consider this pathology when presented with obstipation and B-Symptoms in an adolescent male.

Ileo-colonic lymphoma: presentation, diagnosis, and management

PURPOSE OF REVIEW

The gut-associated lymphoid tissue (GALT), the bulk of which is located in the ileo-colonic region comprises the lymphoid cells of the gastrointestinal tract and confers specific immunological responses. Repetitive antigenic stimulation of these cells predispose to a monoclonal proliferation of this tissue and the eventual development of lymphoma. The gastrointestinal tract is the most commonly involved site of extranodal lymphomas. This review will focus primarily on lymphomas of the ileo-colonic region (defined as the terminal ileum, the colon, and the rectum). We will discuss the epidemiology, pathogenesis, and presentation as well as current practices in diagnosis and management.

RECENT FINDINGS

Despite the majority of the GALT to be located in the ileo-colonic region of the gut, the lymphomas in this location are relatively rare. However, the overall annual incidence of ileo-colonic lymphomas is steadily increasing. This entity has a varied spectrum of clinical presentations. Ileo-colonoscopy with adequate targeted biopsies can serve as a gold standard for definitive diagnosis. Ileo-colonic lymphomas may be managed with chemotherapy alone while surgery is reserved for highly aggressive tumors or clinical emergencies. Radiation is not a preferred adjuvant treatment for lymphomas in this location of the gut. Adequate endoscopic surveillance measures and tools to potentially prevent recurrence and improve the overall prognosis of this disease are lacking.

SUMMARY

Ileo-colonic lymphomas are rare and can present with varied symptoms and signs. Endoscopy with adequate sampling can aid in making a definitive diagnosis. Chemotherapy can be highly effective in management while surgery is indicated for emergency presentations. Adequate endoscopic surveillance tools are lacking, yet imperative to prevent recurrence and improve prognosis.

Primary small cell type of non-Hodgkin lymphoma of the colon: a case report

Introduction

Primary lymphoma of the colon is exceedingly rare and comprises 0.2–1% of all colon tumors. The most common subtype of lymphoma in the colon is non-Hodgkin lymphoma. Symptoms are often nonspecific, and treatment varies between chemotherapy alone and a combination of surgery and chemotherapy.

Case presentation

We describe a case of a Ashkenazi Jew patient who presented in the typical way that carcinoma of the colon might present but turned out to have a very rare type of tumor in both its histology and its location.

Conclusion

There was apparent discordance between the relative bulkiness and gross appearance of the tumor with the unrevealing result of the biopsies, demanding a high level of suspicion as to the actual presence and possible type of such a tumor in the future.

Primary Colonic Lymphoma With Paraneoplastic Hypercalcemia

Primary colonic lymphoma is a rare tumor accounting for 0.1%–0.5% of all colorectal malignancies. We describe a 63-year-old man whose initial presentation was altered mental status due to hypercalcemia. Physical examination revealed a hard, right-sided abdominal mass. Abdominal computed tomography showed a mass in the ascending colon, which on further evaluation with colonoscopy and biopsy was diagnosed as diffuse large B-cell lymphoma. A diagnosis of primary colonic lymphoma was made based on the Dawson criteria, after ruling out any extracolonic involvement. Workup for hypercalcemia showed elevated calcitriol levels, which is a paraneoplastic manifestation of the lymphoma.

Primary colorectal diffuse large B-cell lymphoma initially presenting with pleural effusion: report of one case and review of literature

Gastrointestinal (GI) diffuse large B-cell lymphoma (DLBCL) is one of the frequently reported histologic subtypes of non-Hodgkin lymphoma (NHL) that occur in the GI tract. However, the presentation of quite different clinical manifestations, morphologic characteristics, immunophenotypes, and molecular biologic features is challenging for its diagnosis. Herein, we describe a rare case of primary colorectal DLBCL that occurred in a 59-year-old immunocompetent Chinese female who attended our respiratory clinic for the third time with an asymptomatic pleural effusion and pleural thickening. In her clinical setting, there was no history of trauma or travel, and no evidence of infections, connective tissue diseases, or malignancies such as pleural mesothelioma. Lymphoma was highly suspected for the enlargement of systemic lymph nodes and the multiple polypoid appearance in the rectum found by endoscopy examination. In a repeated colonoscopy, immunohistochemical and molecular features of the multiple "polyps" allowed diagnosis of colorectal diffuse large B-cell NHL. To our knowledge, this is the first case of a verified diagnosis of pleural effusion associated with a primary colorectal DLBCL. The purpose of this report is to alert clinicians that when we evaluate the causes of unexplained pleural effusion, lymphoma should be considered, particularly when the available examination data cannot be corroborated by clinical manifestations.

Primary Diffuse Large B-cell Lymphoma of the Sigmoid Colon

Primary gastrointestinal lymphoma is the most common type of extra-nodal lymphoma, representing about 30%-50% of all extra-nodal involvement. The stomach is the most common site, with the colon and rectum accounting for a minority of occurrences. Primary colorectal lymphoma is uncommon, representing only 0.3% of all large intestinal malignancies and approximately 3% of gastrointestinal (GI) lymphomas, with the majority of these being B-cell non-Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL) being the most common subtype. We present a case of an 85-year-old male who presented with symptoms suggestive of bowel obstruction, who, after further evaluation, was diagnosed with primary non-Hodgkin lymphoma of the colon, DLBCL subtype.

Primary Diffuse Large B-Cell Lymphoma of the Descending Colon

Primary non-Hodgkin lymphoma of the gastrointestinal tract is rare with an incidence of 10-15% of all non-Hodgkin lymphoma cases and 1-4% of all gastrointestinal tumors. The most common sites of involvement include the stomach, small intestines, colon and rectum. Primary colorectal lymphoma is extremely rare representing only 0.2-0.6% of all colorectal malignancies. The presentation is usually non-specific leading to delay in diagnosis. Imaging is used to locate the tumor and its extension. Colonoscopy usually shows a fungating mass, infiltrative or ulcerative lesion. Diffuse large B-cell lymphoma is the most common histological subtype. Management of diffuse large B-cell lymphoma usually involves chemotherapy, radiation, surgery or a combination approach.

Concomitant non-Hodgkin's lymphoma in colon and liver: report of a rare case and review of literature

A 58-year-old male patient was admitted with right upper abdominal pain. Initial hematologic evaluation revealed mildly elevated serum carcinoembryonic antigen and carbohydrate antigen (CA) 19-9 tests, while an abdominal CT-scan showed a circumferential mass along the distal ascending colon and the right flexure of colon, simultaneously a liver lesion in segment 8 is considered metastases from colorectal. colonoscopic examination revealed a circumferential growth tumor in the right flexure of colon and the colonoscopy can not reach the proximal of the tumor. We performed a right hemihepatoectomy and a right hemicolectomy associated with loco-regional lymphadenectomy. Histological examination showed diffuse large B-cell lymphomas in resected right colon as well as liver tumors. The patient received six courses of chemotherapy with CHOP-based regimens. At 14-month follow-up before this report, the patient is still alive and free of disease.

Primary colonic lymphoma: An incidental finding in a patient with a gallstone attack

We report a case of primary colonic lymphoma incidentally diagnosed in a patient presenting a gallbladder attack making particular attention on the diagnostic findings at ultrasound (US) and total body computed tomography (CT) exams that allowed us to make the correct final diagnosis. A 85-year-old Caucasian male patient was referred to our department due to acute pain at the upper right quadrant, spreaded to the right shoulder blade. Patient had nausea and mild fever and Murphy’s maneuver was positive. At physical examination a large bulky mass was found in the right flank. Patient underwent to US exam that detected a big stone in the lumen of the gallbladder and in correspondence of the palpable mass, an extended concentric thickening of the colic wall. CT scan was performed and confirmed a widespread and concentric thickening of the wall of the ascending colon and cecum. In addition, revealed signs of microperforation of the colic wall. Numerous large lymphadenopathies were found in the abdominal, pelvic and thoracic cavity and there was a condition of splenomegaly, with some ischemic outcomes in the context of the spleen. No metastasis in the parenchimatous organs were found. These imaging findings suggest us the diagnosis of lymphoma. Patient underwent to surgery, and right hemicolectomy and cholecystectomy was performed. Histological examination confirmed our diagnosis, revealing a diffuse large B-cell lymphoma. The patient underwent to Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone chemotherapy showing only a partial regression of the lymphadenopathies, being in advanced stage at the time of diagnosis.
