“…The primary tumor is usually found as an isolated nodular lesion in the lungs, abdomen or retroperitoneum in adults [3,4] and intraabdominally in the mesentery and omentum in children [6]. They rarely occur in the genitourinary tract.…”

Inflammatory myofibroblastic tumor with extensive involvement of the bladder in an adolescent: a case report

Inflammatory myofibroblastic tumor (IMT) is a rare lesion of unclear pathogenesis that shows a wide, highly variable spectrum of clinical behavior. We describe the case of a 17-year-old boy with a large IMT that infiltrated the bladder, ileocecal junction, peritoneum and pelvic retroperitoneal space. The tumor was associated with extensive toughening and thickening of the bladder, and, although it showed a tendency for invasive growth, it affected mainly the bladder and adjacent tissue. To the best of our knowledge, this case report is the first to describe an IMT involving the entire bladder and several adjacent pelviabdominal organs. The bladder wall was tough and could hardly be cut by scalpel. Levels of inflammatory response markers such as C-reactive protein fell after surgery.

“…Abdominal and retroperitoneal IMTs, by comparison, are usually larger and more aggressive and show high local recurrence rates [4]. In rare cases, IMTs have been found in the bladder, and some authors have suggested that these tumors are sufficiently different from other IMTs that they should be considered a special category [5].…”

“…This case report complies with the SCARE guidelines and has been reported in line with the SCARE checklist [1] . Inflammatory pseudo-tumours (IPTs) are rare mesenchymal masses that occur in <0.0001% of the population [2] , [3] , [4] . First described as IPTs in 1954 by Uniker and Iversion [4] , these tumours are benign lesions associated with non-specific inflammatory cellular infiltration with spindle-cell proliferation and are often reactive, infective, or immunological in nature [5] .…”

Introduction Inflammatory pseudo-tumour (IPT) of the colon is a rare entity with an obscure pathophysiology and largely indeterminate aetiology. Presentation of case A young male patient presented with an Alvarado score of 9/10 and was admitted for appendectomy. An irregular hepatic flexure mass was discovered intraoperatively. The patient underwent an oncological right hemicolectomy with lymphadenectomy under the supposition that it was malignant and recovered with no short or long-term repercussions. Haemoxylin and eosin staining of the mass revealed features of a benign IPT. Discussion IPTs have clinical and radiological features that may be indistinguishable from those of malignancies, often resulting in extensive oncological resections despite recurrence and malignant transformation being negligibly rare. Conclusion Benign pathologies such as IPT that mimic malignancy can sometimes result in extensive investigations or radical resections, the justification of which can only be a point of contention in retrospect. The following report explores our experience with one such patient and is accompanied by a review of the literature.

A caecal pseoudotumour with an incidental adenomatoid testicular tumour in a man with right undescended testis: a case report

et al. 2016

BackgroundInflammatory pseudotumour refers to a non-malignant tumour-like mass resulting from an inflammatory reaction that is composed of granulation tissue with leukocyte infiltration that commonly occurs in the paediatric or young adult population. These tumours occur more commonly in the lungs and the orbit but rarely does it affect the gastrointestinal tract. It poses a clinical diagnostic challenge since it is a benign condition than can mimic the malignant counterpart. Our case is a rare presentation of the caecal pseudotumour in the presence of a right undescended abdominal testis evaluated as a caecal tumour with a differential diagnosis of a testicular malignancy.Case presentationWe report a 53-year-old male who presented with clinical signs suggestive of right colon tumour and undescended right testis. Intra-operatively, a caecal mass was found with no clearly discernable appendix and extensive adhesion of the right colon to the retroperitoneum, to the liver and gall bladder. A testis was found adherent to the posterior aspect of the caecum and terminal ileum. A right hemicolectomy was performed. Histopathology findings revealed an inflammatory mass with abundant fibroblast proliferation and chronic inflammatory cells infiltrate, involving bowel wall and periceacal adipose tissue; no malignant cells were identified. The testis had within it an adenomatoid tumour nodule. He had uneventful recovery and was discharged home 7 days post-operatively. At the moment, he is symptoms free.ConclusionsThe occurrence of right colonic inflammatory pseudotumour and co-existent adenomatoid testicular tumour arising from a cryptorchid testis is very unusual. This would make one incline towards a malignant testicular lesion in the presence of cryptorchidism. Testicular adenomatoid tumour is a rare benign neoplasm, mostly affecting fully descended testis and usually does not warrant orchidectomy for purposes of preserving testicular function. On the other hand, surgical resection remains the only safe and curative treatment option available for inflammatory pseudotumours.
