Abstract
ABSTRACT Inflammatory myofibroblastic tumours (IMTs) are rare soft tissue tumours. Reports of gastrointestinal tract, liver and pancreas tumours are limited. The objective of this study is to identify presenting features, contributing prognostic / etiological factors and any variability in outcomes in the context of different historical treatments. We retrospectively reviewed the records of seven children treated at our hospital between 2006 and 2019 and assessed the demographic, presentation, treatment, immunohistochemistry, and outcomes of their tumours. Age range at presentation was 4 months-15 years with a male predominance. Presentations were typically due to local mass effect or incidental discovery. Systemic symptoms were rare. Outcomes were good with six out of seven stable or in remission irrespective of treatment. Surgical resection where possible is the treatment of choice. Medical therapy had good outcomes with chemotherapy acting as first line treatment when required. The only negative prognostic factor identified was local spread at the time of presentation.

Abstract
OBJECTIVE The inflammatory myofibroblastic tumor (IMT) is a neoplasia with intermediate biological potential, infrequent, with an unpredictable clinical prognosis and a low recurrence rate after an effective treatment. We report two cases of IMT with genitourinary localization, being this entit's publications infrequent. Both presented with little symptomatology, leading to multiple differential diagnosis. The surgical treatment was chosen and pathologic result confirmed the diagnosis. CONCLUSION This entity must be considered as a true malignant neoplasm with aggressive local behavior. The gold standard management is complete surgical resection, with low recurrence rate after it. A new oncological monitoring scheme is proposed, upon the lack of an active surveillance algorithm after treatment.

Abstract
Pseudotumours are well recognised as a complication of metal-on-metal hip arthroplasties and are thought to develop on the basis of an innate and adaptive immune response to cobalt-chrome (Co-Cr) wear particles. We report a case of a large pseudotumour that developed following a knee endoprosthetic replacement (EPR) undertaken for Ewing sarcoma. The lesion contained necrotic and degenerate connective tissue in which there were numerous scattered metal wear-containing macrophages, eosinophil polymorphs, lymphocytes, plasma cells and aseptic lymphocyte-dominated vascular-associated lesion-like lymphoid aggregates. Metal ion levels were elevated. No evidence of infection or tumour was noted and it was concluded that the lesion was most likely an inflammatory pseudotumour developing on the basis of an innate and adaptive immune response to components of Co-Cr metal wear derived from the knee EPR.

Abstract
Inflammatory pseudotumour (IP), also known as inflammatory myofibroblastic tumour (IMT), is a rare lesion of the maxillofacial skeleton and a diagnosis by exclusion. We describe three cases which affected the maxilla, two women and one man of ages 67, 56 and 70 years at presentation. All showed the typical, rather non-specific histopathological features. IgG4-positive plasma cells varied greatly in prominence, and none of the three lesions expressed ALK-1. Both women responded to steroids and radiotherapy, though one also required azathioprine. Despite maxillectomy, radiotherapy, steroids and cyclophosphamide, the man suffered intracranial spread and succumbed to persistent disease. The cases described here demonstrate the clinicopathological difficulties presented by this entity and its aggressive, unpredictable behaviour.

Abstract
PURPOSE This study aims to provide an overview of the literature on mesenteric/omental inflammatory pseudotumors (IPTs). METHODOLOGY We present a new case of mesenteric IPT. We also conducted a systematic search of the English-language medical literature using PubMed, Medline, Google, and Google Scholar related to mesenteric or omental IPTs. The following search terms were used in various combinations: inflammatory myofibroblastic tumor, IPT, mesentery, and omentum. The search included articles published in the English language between January, 1978 and April, 2014. Studies were excluded if the full text was unavailable or missing information prohibited comparisons. RESULTS A total of 30 reports concerning 36 patients with inflammatory pseudotumors meeting the aforementioned criteria were included. The patients were aged from 10 months to 68 years (mean, 19.98 ± 20.5 years); 12 were female (16.75 ± 16.97 years; range, 10 months to 68 years) and 24 were male (21.6 ± 21.9 years; range, 18 months to 63 years). Detailed clinical and pathologic characteristics of 36 patients with IPTs are provided in Table 1. CONCLUSION IPTs may be definitively diagnosed only by histopathological examination and are most effectively treated by resection with negative surgical borders. No consensus has yet been reached regarding when nonsurgical treatment options are most appropriate in management of these lesions. IPTs often recur locally, while distant metastases are very rare. Postoperative close surveillance is essential to detect recurrences early.

Abstract
AIM: To follow up patients with pseudotumoral chronic pancreatitis (PCP) to assess their outcome and identify an optimal surveillance interval.
METHODS: Data obtained prospectively were analyzed in a retrospective manner. Patients with clinical evidence of chronic pancreatitis (abdominal pain in the epigastrium, steatorrhea, and diabetes mellitus), endoscopic ultrasound (EUS) criteria > 4, and EUS-fine needle aspiration (FNA) were included. A pseudotumor was defined as a non-neoplastic space-occupying lesion, a cause of chronic pancreatitis that may mimic changes typical of pancreatic cancer on CT or endoscopic ultrasound but without histological evidence. A real tumor was defined as a neoplastic space-occupying lesion because of pancreatic cancer confirmed by histology.
RESULTS: Thirty-five patients with chronic pancreatitis were included, 26 (74.2%) of whom were men. Nine (25.7%) patients were diagnosed with pseudotumoral chronic pancreatitis and two (2/35; 5.7%) patients with pseudotumoral chronic pancreatitis were diagnosed with pancreatic cancer on follow-up. The time between the diagnosis of pseudotumoral chronic pancreatitis and pancreatic adenocarcinoma was 35 and 30 d in the two patients. Definitive diagnosis of pancreatic adenocarcinoma was made by surgery. In the remaining six patients with pseudotumoral chronic pancreatitis, the median of follow-up was 11 mo (range 1-22 mo) and they showed no evidence of malignancy on surveillance. In the follow-up of patients without pseudotumoral chronic pancreatitis but with chronic pancreatitis, none were diagnosed with pancreatic cancer. According to our data, older patients with chronic pancreatitis are at risk of pseudotumoral chronic pancreatitis.
CONCLUSION: According to characteristics of patient, detection of PCP should lead a surveillance program for pancreatic cancer with EUS-FNA in < 1 mo or directly to surgical resection.

Abstract
Inflammatory pseudotumor (IPT) is a rare, locally aggressive, benign neoplasm of unknown etiology. It is uncommon in the head and neck region, particularly in the paranasal sinuses. We present an unusual case of IPT of the maxillary sinus and orbit in a 27-year-old woman who presented with cheek swelling, right orbital swelling, double vision, and associated fever and trismus. Computed tomography identified a mass with radiologic features suggestive of a malignancy of the maxillary sinus and orbit; the mass extended into the infratemporal fossa, parapharyngeal space, anterior antral wall, and surrounding soft tissue. A diagnosis of IPT was established on the basis of histologic and immunohistochemical analysis, which identified a proliferation of bland spindle cells and a mixed inflammatory cell infiltrate. Despite its aggressive appearance, IPT is associated with a good prognosis. Our patient was treated successfully with a combination of surgery, steroid therapy, and methotrexate. Chemotherapeutic agents are generally reserved for recalcitrant cases.

Abstract
OBJECTIVE To summarize the clinical characteristics of inflammatory myofibroblastic tumor (IMT) in head and neck and to discuss its treatment. METHODS Twenty-seven cases of IMT in head and neck diagnosed at the Chinese PLA General Hospital from 2004 to 2012 were analyzed retrospectively. Among the 27 patients, 12 males and 15 females, age ranged from 8 to 77 years, with a median 43 years old. Treatment included: 1 with radiotherapy, 22 with surgery, 3 with surgery and postoperative radiotherapy, one with concurrent chemoradiotherapy followed by surgery. Of the 27 cases, 5 located in the neck, 6 in the nasal and paranasal sinus, 4 in the temporal bone, 3 in the throat, 2 in the parotid gland, 2 in the lower pharynx, 1 in the mandible, 1 in the maxilla, 1 in the masseter muscle, 1 in the amygdala and 1 in the pharynx nasalis. RESULTS Following-up time was 4-85 months, with a median of 26 months. Six cases lost follow-up, 1 case with malignant transformation and died, 16 cases survived with no recurrence, 4 cases relapsed, of whom 2 were alive with tumors and 2 died. CONCLUSIONS IMT in the head and neck has a tendency to be malignancy, with certain recurrence rate and mortality. Radical excision is still the first choice of treatment for IMT in head and neck.

Abstract
A 63-year-old man presented with an exceptionally rare case of intracranial inflammatory pseudotumor manifesting as speech and gait disturbance. Magnetic resonance imaging showed a left convexity mass with significant peritumoral edema. The mass was attached to the convexity dura and mimicked meningioma. Angiography showed tumor staining, so the tumor was embolized using a gelatin sponge by an intravascular technique. The elastic hard tumor was totally resected without much bleeding. Histological examination showed proliferation of spindle cells and capillaries with nonspecific infiltrate of inflammatory cells consisting of plasma cells, eosinophil granulocytes, lymphocytes, and macrophages. The spindle cells were immunopositive for vimentin. The plasma cells were immunopositive for CD138, epithelial membrane antigen, and IgG. Only a small number of IgG4-positive cells were observed. The diagnosis was consistent with inflammatory pseudotumor. This disease entity, the histological differential diagnosis, its subtypes, and preoperative embolization are discussed.

Abstract
Inflammatory pseudotumor (IPT) of the liver is a rare benign lesion for which imaging diagnosis remains a challenge. We report the case of a 39-year-old Algerian woman, who presented epigastric pains combined with fever and jaundice. Ultrasound, CT scan and MRI showed the presence of a 10 cm-long multi-septated cystic mass of the left lobe, with peripheral enhancement. A left-hepatectomy was performed and histopathology revealed an IPT of the liver. During the 4 following years, the patient had three other recurrences of liver IPT at various locations distinct from the original, revealed by the same clinical symptoms. During these relapses, the lesions did regress thanks to a medical treatment. This observation underlines the difficulty of the diagnosis and treatment of liver IPT.

Abstract
We describe the main characteristics and treatment of urogenital manifestations in patients with Wegener granulomatosis (WG). We conducted a retrospective review of the charts of 11 patients with WG. All patients were men, and their median age at WG diagnosis was 53 years (range, 21-70 yr). Urogenital involvement was present at onset of WG in 9 cases (81%), it was the first clinical evidence of WG in 2 cases (18%), and was a symptom of WG relapse in 6 cases (54%). Symptomatic urogenital involvement included prostatitis (n = 4) (with suspicion of an abscess in 1 case), orchitis (n = 4), epididymitis (n = 1), a renal pseudotumor (n = 2), ureteral stenosis (n = 1), and penile ulceration (n = 1). Urogenital symptoms rapidly resolved after therapy with glucocorticoids and immunosuppressive agents. Several patients underwent a surgical procedure, either at the time of diagnosis (n = 3) (consisting of an open nephrectomy and radical prostatectomy for suspicion of carcinoma, suprapubic cystostomy for acute urinary retention), or during follow-up (n = 3) (consisting of ureteral double J stents for ureteral stenosis, and prostate transurethral resection because of dysuria). After a mean follow-up of 56 months, urogenital relapse occurred in 4 patients (36%). Urogenital involvement can be the first clinical evidence of WG. Some presentations, such as a renal or prostate mass that mimics cancer or an abscess, should be assessed to avoid unnecessary radical surgery. Urogenital symptoms can be promptly resolved with glucocorticoids and immunosuppressive agents. However, surgical procedures, such as prostatic transurethral resection, may be mandatory in patients with persistent symptoms.

Abstract
Haemophilia, a lifelong congenital bleeding disease, is a highly demanding disorder, due to the costs of its replacement therapy. In the absence of this pivotal treatment, life expectancy and quality of life are deleteriously affected. As illustration, we present a 14 years long follow-up of a patient with severe haemophilia A, treated sporadically with fresh plasma, cryoprecipitate and factor concentrates, who developed a giant iliopsoas pseudotumor. Since he was an infant, under on demand therapy with fresh frozen plasma, cryoprecipitate and low doses of factor concentrates he presented many spontaneous bleedings, developing multiple disabling arthropathies. At the age of 14 years, an iliopsoas hematoma occurred, which relapsed several times, developing an iliopsoas pseudotumour. After 5 years, sepsis with Klebsiella was diagnosed. A CT scan revealed fistula between the pseudotumor and the gut. Under antibiotics, the evolution of sepsis improved, but over a period of 10 months 5 episodes of haematemesis and melena, followed by one episode of macroscopic haematuria occurred; two months later he developed an inguino-crural mass, which fistulized through the abdominal wall. A mixt german-romanian team solved the clinical concern. After 108 hospitalization days and consumption of 104840 IU factor VIII he left the clinic in good condition. One year later, the temporary colostomy with anus praeter was closed. The follow-up reveals now, after almost 10 years with favourable outcome, that the patient is well, active within his family and profession.

Abstract
OBJECTIVE To discuss the diagnosis and treatment of plasma cell granuloma in the head and neck region. METHOD Retrospective analysis of 3 cases of plasma cell granuloma occurred in head and neck. One case treated with endoscopic surgery and nasal and oral steroids after operation. Two cases treated with Caldwell-Luc style resection, followed by oral steroids and radiotherapy, one of the two cases combined with chemotherapy simultaneously. RESULT The patient done with endoscopic surgery followed up for 5 years, there was no tumor recurrence in the nasal cavity and maxillary sinus openings and sinus lining. Paranasal sinus CT was examed on the patient done with partial resection and radiotherapy 2 years after operation, no residual tumor proliferation. The third patient underwent paranasal sinus CT examination 3 years after operation, and no limitation of mouth opening was found. CONCLUSION The incidence rate of Plasma cell granuloma occured in head and neck is low. It is an inflammatory disease, but its physical signs and imaging findings are similar to malignant tumors. Because of the invasion feature, surgical resection should be the first choice, and if combined with radiotherapy and chemotherapy, the prognosis could be better.

We report the case of a 32-year-old patient with Wegener's granulomatosis (WG) associated with a (biopsy - proven) renal inflammatory pseudotumour (IPT) of the left kidney treated by a partial nephrectomy, glucocorticoids and immunosuppressive drugs, in whom a relapse of renal IPT was found 6 years after the diagnosis of the first IPT. The originality of this observation lies in the fact that a relapse of IPT has never been described and also in the fact that complete regression of the IPT relapse was obtained with immunosuppressive treatment, while renal IPTs are currently treated by total or partial resection of the kidney. Finally, we discuss the potential benefits of an integrated 18fluorodeoxyglucose PET/CT for the follow-up of WG, since this imaging technique contributed to the management of the present case.

Abstract
Inflammatory pseudotumors are histologically benign but locally destructive lesions that are usually found in the lung, although some cases of temporal bone involvement have been reported. To the best of our knowledge, no case of simultaneous involvement of the temporal bone and the lung has been previously reported in the literature. We describe such a case in a 39-year-old man. The temporal bone lesion was removed in its entirety, and the lung lesion was treated with steroid therapy. At the 2-month follow-up, the size of the lung mass on chest x-ray was significantly reduced, and at 1 year, the patient was asymptomatic.

Abstract
Inflammatory pseudotumor of the bladder is a benign proliferative lesion of the submucosal stroma that cannot be distinguished from malignant tumors of the bladder either endoscopically or radiographically. Although benign, the proliferative nature of the inflammatory pseudotumor histopathology has led others to recommend open surgical removal or complete transurethral resection for definitive treatment. A limited number of case reports have described inflammatory pseudotumor of the bladder in either adults or children. This is a case of biopsy-proven inflammatory pseudotumor in the bladder of a child that regressed after medical management alone.

Abstract
We describe the management of a young boy with mild haemophilia A and a massive iliac pseudotumour with a multi modality approach involving factor replacement, radiation therapy, embolization and surgery. The patient was initially treated with recombinant factor VIII and radiation therapy. Because of inadequate response and worsening of bony erosion, the patient had a preoperative embolization followed by surgical excision. The surgical procedure was associated with minimal blood loss and the patient had a relatively smooth postoperative course with no physical morbidity. This case illustrates successful aggressive management of a large, proximally located pelvic pseudotumour, which resulted in an excellent outcome despite the need for a normally morbid operation.

Abstract
INTRODUCTION Inflammatory myofibroblastic tumors (IMT) while uncommon may arise within numerous organs. Historically, the literature regarding IMT has been confined to small one organ case series, with few reviews encompassing multiple anatomic sites, and little data regarding adjuvant treatment. METHODS A review of patients with IMT treated at two large academic medical centers over a 15-year period was undertaken. Patient demographics, pathologic diagnoses, and pertinent clinical data were obtained. RESULTS Forty-four cases of pathologically confirmed IMT were identified. Tumor locations included multiple anatomic sites. Therapies included complete resection, incomplete resection, observation, or chemotherapy, and/or radiation. Five patients underwent adjuvant chemotherapy and/or radiation therapy following surgery (14%) for local aggressiveness of the tumor, invasion, positive margins, or location of tumor that was not amenable to surgical resection. A second, concomitant, histologically distinct, neoplasm was identified in five cases. Of the patients who underwent treatment three local recurrences were noted (8%) and occurred in patients with partial resection without adjuvant chemo- or radiotherapy. CONCLUSIONS Inflammatory myofibroblastic tumors may be a locally aggressive and destructive neoplasm. Tumor recurrence is unusual following complete surgical resection or organ-preserving combined modality therapy.

Abstract
BACKGROUND Plasma cell granulomas are rare and heterogeneous tumor-like lesions of mixed inflammatory cell infiltrates of unknown etiology. Although they have the potential to occur in sites throughout the body, their occurrence in the paranasal sinuses and nasal cavity is uncommon and often associated with unique clinical characteristics and natural history. METHODS We present a case of an aggressive plasma cell granuloma of the maxillary sinus and a review of the literature (28 cases). RESULTS The patient was treated with definitive radiotherapy (45 Gy in 25 fractions) and experienced a local recurrence 2 years later. The lesion initially responded to corticosteroids and then progressed. Resection was performed and was followed by another recurrence. The patient was treated with radiosurgery and is disease free 8 years after initial treatment. CONCLUSIONS Review of the literature indicates that the optimal first line of treatment is high-dose corticosteroids. Surgery is indicated if the lesion fails to respond. Radiotherapy is indicated if complete resection is not feasible.

Abstract
Inflammatory pseudotumor is a non-neoplastic process of unknown etiology characterized by a proliferation of connective tissue with an inflammatory infiltrate. Intracranial inflammatory pseudotumors classically involve the cavernous sinus but can also occur in the supratentorial or infratentorial compartments and spinal canal. Symptoms are dependent on location, and, when present in the cavernous sinus, typically include cranial nerve palsies of those nerves in the cavernous sinus. These lesions are rapidly responsive to steroid therapy. Surgery is typically indicated for biopsy only, but complete resection may be justified for lesions outside the cavernous sinus.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor, composed of myofibroblastic spindle cells with acute and chronic inflammatory cells, is an unusual, benign solid mass that mimics a neoplastic process. METHODS We report a rare case of a patient with a laryngeal inflammatory myofibroblastic tumor. Laryngoscopy demonstrated a submucosal mass involving the right false cord. The mass was a well-enhanced supraglottic lesion on CT scan. It showed medially high signal intensity and peripherally low signal intensity on T2-weighted MR images, and it displayed a high magnetization transfer ratio; before surgery, it was believed to be a malignant tumor. Laryngoscopic biopsy was performed. Pathologic features of the specimen were diagnostic for inflammatory myofibroblastic tumor. RESULTS Steroid therapy was chosen for further treatment. No recurrence was observed for 4 years. CONCLUSION In patients with chronic hoarseness who have a malignant-looking submucosal laryngeal mass, inflammatory myofibroblastic tumor should be considered. Conservative surgery and steroid treatment are advocated because of laryngeal preservation.

Abstract
Inflammatory pseudotumor (IPL) of the liver is a rare benign clinicopathologic entity, which has been associated with infectious conditions, including alimentary, digestive tract and mouth infections. We report a new case, where a patient developed hepatic IPL that revealed endometritis related to Corynebacterium infection; the patient had a favorable outcome of hepatic IPL after appropriate antibiotic therapy initiation. Our findings therefore confirm that antibiotic therapy may be effective in patients with hepatic IPL associated with underlying infections, avoiding unnecessary surgery. Our data also indicate that when hepatic IPL is observed, a complete clinical evaluation, including gynecological evaluation, should be systematically performed.

Abstract
CONCLUSIONS Inflammatory pseudotumours in the maxillary sinus may present as malignant tumours and manifest locally aggressive features characteristic of such tumours. Despite their locally destructive features, they pursue a benign course after local excision. OBJECTIVE Inflammatory pseudotumour (plasma cell granuloma) is an uncommon non-neoplastic lesion comprising a proliferation of spindle myofibroblasts and chronic inflammatory cells. Despite its benign histopathological nature, it may exhibit aggressive behaviour that is yet to be characterized in the head and neck area. MATERIAL AND METHODS We present the cases of two adult patients with inflammatory pseudotumour arising from the maxillary sinus. Immunohistochemistry and polymerase chain reaction for immunoglobulin from tissue sections were performed to confirm the polyclonality of the infiltrating plasma cells. RESULTS CT and MRI disclosed expansive soft masses eroding surrounding soft and bony tissues. Histopathologically, the lesions were unencapsulated and composed of numerous plasma cells, histiocytes and spindle cells with minimal nuclear pleomorphism.

Abstract
Plasma cell granulomas are lesions of uncertain histogenesis arising in a variety of locations, most commonly the lung. Treatment for these lesions is complete surgical excision if possible. Unresectable pulmonary lesions respond to oral corticosteroids and radiation therapy. We report the long-term outcome of two unusual pediatric cases of cardiac plasma cell granulomas originating within the right ventricle and posterior aspect of the left ventricle. The limited literature reports advocate surgical resection for this entity, with no discussion of alternative treatment strategies for unresectable lesions. We prospectively evaluated the response to postoperative oral steroid therapy, as complete surgical excision was not possible in either case. Sequential echocardiography demonstrated additional significant reduction in the size of the masses and the patients remain asymptomatic at 9 and 5.5 years follow-up, without evidence of obstruction or recurrence. Oral corticosteroids should be considered as a treatment option for any unresectable plasma cell granuloma.

Abstract
BACKGROUND/PURPOSE pulmonary (PPT) and extrapulmonary pseudotumors (EPPT) are uncommon benign tumors, which, in general, do not recur after complete resection. Recurrence rates for both types of pseudotumors are undocumented in a large population of children, and the salient features of potential recurrences are unspecified. METHODS This is a report of 15 children with PPT and EPPT; 3 children had a recurrence. These pseudotumors recurred despite adequate primary resection of all gross disease at first presentation. The literature was reviewed to determine rate of recurrence for PPT and EPPT and also to document features common to recurrent pseudotumors. RESULTS Overall recurrence rate for pseudotumors was 14%. PPT and EPPT, which were not confined to a single organ, had a high chance of recurrence (46% and 30%, respectively) compared with PPT and EPPT, which were confined to a single organ (1.5% and 8%, respectively). Recurrences have appeared between 3 months and 7 years. Intraabdominal EPPT accounts for more than 75% of the EPPT recurrences. CONCLUSIONS PPT and EPPT recur more frequently than anticipated. All pseudotumors, which on initial presentation extend beyond the confines of a single organ, have a high chance of recurrence despite what appears to be adequate resection. Children with pseudotumors that extend beyond a single organ, require frequent postoperative evaluation for recurrence and may be candidates for chemotherapy or radiotherapy at the time of initial resection.

Abstract
An exceptional cause of obstructive jaundice is reported in the present case. A 51-year-old woman progressively developed jaundice with pruritus, and abdominal ultrasonography revealed dilated intra- and extrahepatic bile ducts. Endoscopic retrograde cholangiography and endoscopic ultrasonography showed a tumor in the distal common bile duct, but failed to determine the nature of the lesion, and the patient underwent a pancreaticoduodenectomy. The final diagnosis was an inflammatory pseudotumor of the common bile duct. Inflammatory pseudotumors are uncommon, without evident pathogenesis, and are described in many organs. The localization in the common bile duct is exceptional. The prognosis is good, and a more conservative approach is possible if the diagnosis is certain before surgery.

Abstract
Inflammatory pseudotumor is a quasineoplastic lesion that most commonly involves the lung and the orbit, but it has been reported to occur in nearly every site in the body. The pathogenesis, natural history, clinical presentation, imaging findings, and treatment options for inflammatory pseudotumor in the lung, heart, gastrointestinal tract, adrenal gland, iliopsoas muscle, orbit, and central nervous system are discussed. Because inflammatory pseudotumors mimic malignant tumors both clinically and radiologically, the radiologist should be familiar with this entity and help avoid unnecessary radical surgery when possible.

Abstract
BACKGROUND Inflammatory pseudotumor of the liver (IPL) is an unusual tumor-like condition that is becoming recognized as an important differential diagnosis in the patient presenting with liver masses. This report describes six cases of IPL. STUDY DESIGN Clinical, diagnostic, pathologic, and followup data were collected prospectively on six patients presenting to a specialist hepatobiliary unit. RESULTS Six patients with IPL presented over a 2-year period. Median age was 35 years (range 2 to 79 years) and five patients were men. Three patients were Polynesian (Tongan and Samoan) and one was New Zealand Maori. Five patients presented with nonspecific symptoms (fever, arthralgia, myalgia) and IPL was an incidental finding in one patient. At presentation, four patients had elevated white cell counts, and five patients had abnormal liver function tests with elevations in alkaline phosphotase and gamma-glutamyl transferase the most commonly seen. Carcinogenic embryonic antigen and alpha fetoprotein were normal in all patients, although one was a known hepatitis B carrier. In all cases of IPL, diagnosis was made on core biopsy of the liver lesions and all patients were managed nonoperatively with complete resolution of the tumors. Two patients had marked reduction in systemic symptoms (fever and pain) from a short course of oral steroids. CONCLUSIONS IPL appears to be a relatively common problem in Maori and Polynesians. Recognition and differentiation of this condition from malignant liver lesions are important to avoid unnecessary surgery.

Abstract
The inflammatory myofibroblastic tumor (IMT) is a space-occupying lesion of unknown etiology and a distinctive but controversial lesion. This type of tumor is recently considered neoplastic rather than inflammatory. It is usually occurring during childhood, composed of fascicles of bland myofibroblastic cells admixed with a prominent inflammatory infiltrate consisting of lymphocytes, plasma cells, and eosinophils. IMT of the maxilla is very rare. The diagnosis of IMT can be made on the basis of histopathology and immunohistochemistry. Herein, we presented a patient who had IMT of the maxillary sinus that was initially misinterpreted as a malignant neoplasm upon clinical and radiographic examinations. We discussed the diagnostic and therapeutic procedures and may consider it a true neoplasm.

Abstract
Pulmonary inflammatory pseudotumors are usually unique lesions of unknown etiology with good prognosis. We report two severe cases with mediastinal invasion, local recurrence, extrathoracic locations, one of them with a fatal evolution. Certain microscopic features, which were present in our cases (increased cellularity, nuclear pleomorphism, mitotic activity, focal necrosis, bizarre giant cells, vascular invasion), may have prognostic relevance in determining an aggressive behavior of these tumors. Surgical resection is the recommended treatment, and incomplete resection, as in our cases, seems to be a risk factor for developing recurrent inflammatory pseudotumor. Immunosuppressive therapy was ineffective as well as radiotherapy in one of our cases. Only high doses of corticosteroids seemed to slow the evolution of the disease.

Abstract
We report the clinical course and pathologic findings in a case of intraocular sclerosing inflammatory pseudotumor in a 21-year-old man. The patient initially had a unilateral right interstitial keratitis, scleritis, uveitis, ciliary body mass, and retinal detachment. Scleral and vitreous biopsy specimens revealed an inflammatory process. The eye was eventually enucleated despite therapy with high doses of prednisone and ciprofloxacin hydrochloride. Histologic examination of the globe showed nongranulomatous, acute (neutrophils) and chronic (lymphocytes and histiocytes) inflammation with proliferation of fibrous tissue within the vitreous cavity, uvea, sclera, and contiguous orbital fibroadipose tissue. The contralateral eye later developed a similar mass that resolved following aggressive and prolonged immunosuppressive therapy with retention of 20/16 visual acuity.

This article focuses on the origin, diagnosis, and management of focal benign lesions of the liver. The most common lesions include cavernous hemangioma, focal nodular hyperplasia, hepatic adenoma, and nodular regenerative hyperplasia. A number of less frequent occurring lesions are also discussed. In general, the common lesions can be diagnosed by radiologic imaging, but occasionally biopsies are required, and surgical removal is often needed.

Abstract
Inflammatory pseudotumor is rare benign lesion ad uncommon is a multiple localization of the liver and spleen. We report a case of inflammatory pseudotumor of the liver associated with an other lesion in the spleen, a 53-years-old ma in which we observed the evolution of clinical picture. Making the diagnosis is often difficult, despite the use of the modern imaging and laboratories techniques, and generally these masses often confuse with others lesions, such as primary or secondary neoplasm, because the clinical presentation and morphological appearance are often unspecific. The medical treatment seems to be more appropriate for patients when it is possible make a correct diagnosis with a biopsy of the lesion. In the other cases, the surgical procedure is the best treatment that must be supported by histologic examination.

Abstract
Pseudotumor is a term used to describe a space-occupying inflammatory lesion of unknown etiology that clinically simulates a neoplastic process. Pseudotumors of the fossa pterygopalatina and fossa infratemporalis are very rare. In this paper, we describe a patient who developed a pseudotumor in the left fossa pterygopalatina, secondary to an unclassified autoimmune disease, which caused progressive left-sided facialdynia and swelling. The tumor was detected with somatostatin receptor scintigraphy. The lesion was refractory to steroids, also in combination with azathioprine, as well as to surgical intervention. An excellent clinical response was observed after cyclosporine was added. This case is presented here in order to draw attention to the use of somatostatin receptor scintigraphy as a diagnostic tool in visualizing pseudotumors and to document a case that responded excellently to treatment with a combination of low-dose cyclosporine and steroids.

Abstract
Two cases of iliopsoas haemophilic pseudotumours are presented. In one patient a fistula developed between a pseudotumour and the large bowel. This resulted in an abscess involving the pseudotumour and adjacent tissues. It resolved after 5 years of therapy involving percutaneous drainage and closure of the fistula. The second patient had a massive pseudotumour that had obstructed both ureters. Later he suffered a fatal mixed Gram negative septicaemia probably related to erosion into the colon.

Abstract
Inflammatory pseudotumor of the spleen is a benign tumorous lesion of unknown etiology and pathogenesis that has been described in only a few cases in the literature. Recognition of this rare entity is important, as the clinical manifestations and imaging features could be indistinguishable from a lymphoproliferative disorder or another malignancy of the spleen. We report a new case and review the clinical presentation, laboratory findings, pathological and immunohistochemical studies, treatment, and prognosis of the previously reported cases of inflammatory pseudotumor of the spleen.

Abstract
A 2-year-old girl presented with signs and symptoms of cardiac tamponade preceded by upper respiratory tract infection. A two-dimensional echocardiogram was suggestive of an intrapericardiac tumor. Exploration of the pericardium revealed a large amount of dense amber-colored "coagulated material." Microscopic examination of the material and the pericardium was diagnostic of acute pericarditis. Based on this experience we propose the term pseudotumor of the pericardium for this form of coagulated pus. We also propose that this term should be added to the differential diagnosis of intrapericardiac tumor.

Abstract
Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor is a spindle cell proliferation of disputed nosology, with a distinctive fibroinflammatory and even pseudosarcomatous appearance. Although the lung is the best known and most common site, inflammatory myofibroblastic tumor occurs in diverse extrapulmonary locations. We report our experience with 84 cases occurring in the soft tissues and viscera of 48 female patients and 36 male patients between the ages of 3 months and 46 years (mean, 9.7 years; median, 9 years). A mass, fever, weight loss, pain, and site-specific symptoms were the presenting complaints. Laboratory abnormalities included anemia, thrombocytosis, polyclonal hypergammaglobulinemia, and elevated erythrocyte sedimentation rate. Sites of involvement included abdomen, retroperitoneum, or pelvis (61 cases); head and neck, including upper respiratory tract (12 cases); trunk (8 cases); and extremities (3 cases). The lesions ranged in size from 1 to 17 cm (mean, 6.4; median, 6.0). Excision was performed in 69 cases. Eight had biopsy only. Five patients received chemotherapy or radiation in addition to undergoing biopsy or resection as initial treatment. Sixteen patients had multinodular masses involving one region. Clinical follow-up in 53 cases revealed that 44 patients were alive with no evidence of disease, four were alive with IMT, and five were dead. Thirteen patients had one or more recurrences at intervals of 1-24 months (mean, 6 months; median, 10 months). No distant metastases were documented. The five patients who died had complications either due to the location of the lesion (heart, peritoneum, retroperitoneum, or mesentery) or related to treatment (lymphoproliferative disorder following hepatic transplantation; sepsis following wound infection). The abdominal masses were the largest. All tumors were firm and white with infiltrative borders and focal myxoid change. Three basic histologic patterns were recognized: (a) myxoid, vascular, and inflammatory areas resembling nodular fasciitis; (b) compact spindle cells with intermingled inflammatory cells (lymphocytes, plasma cells, and eosinophils) resembling fibrous histiocytoma; and (c) dense plate-like collagen resembling a desmoid or scar. Immunohistochemistry demonstrated positivity for vimentin, muscle-specific actin, smooth muscle actin, and cytokeratin consistent with myofibroblasts. Based on this series, inflammatory myofibroblastic tumor is a benign, nonmetastasizing proliferation of myofibroblasts with a potential for recurrence and persistent local growth, similar in some respects to the fibromatoses.

Abstract
Inflammatory pseudotumors (IPT) of the liver are rare benign tumors of unknown origin. Most previously reported cases were initially misdiagnosed and treated surgically; thus, their course under medical treatment remains unclear. We report an additional case of hepatic IPT with a favorable outcome under medical treatment without surgical resection. New imaging and pathologic features of this disease are presented that may facilitate preoperative recognition and appropriate treatment.
