Primary retroperitoneal mucinous cystadenoma: A case report with review of literature.

Introduction and importance: Primary Retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare benign tumor, predominantly occurring in women, with unclear pathogenesis. Case presentation: A 31-year-old woman, with no medical or surgical history, presented with left flank pain. Clinical discussion: An abdominal computed tomography (CT) scan revealed an 11cm retroperitoneal cyst. Due to its large size, percutaneous CT-guided drainage followed by a laparotomy surgical resection, were performed. Post-operative course was uneventful. Histological and immunohistochemical findings were consistent with PRMC. The patient was disease-free after a 6-month follow-up. Conclusion: Mucinous cystadenoma is a very odd finding in the retroperitoneum. Multiple differential diagnoses are to be considered beforehand, as most of cystic lesions in this anatomical region are malignant and require a different surgical approach. Radical resection, by laparotomy or laparoscopy, is the treatment of choice.

A Giant Ureteral Inflammatory Myofibroblastic Tumor in a 4-Year-Old Child: A Case Report and Review of the Literature.

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm of children and young adults. It consists of myofibroblastic cells of borderline malignancy admixed with inflammatory cells. According to the WHO classification, of tumors, it is a soft-tissue tumor with an intermediate malignant potential. It may arise within numerous organs. Ureteral location is exceedingly rare. We report the exceptional case of a 4-year-old boy presenting with a giant right ureteral IMT removed during a nephroureterectomy. Histology and immunohistochemistry confirmed the diagnosis of an IMT with Anaplastic Lymphoma Kinase 1 expression. A 7 months follow-up showed no recurrence or distant metastasis. We also reviewed the literature for similar cases of pediatric ureteral IMT.

Right-sided varicocele thrombosis complicating an acute epididymo-orchitis: A case report and review of the literature.

Unilateral right-sided varicocele is a rare and warning condition that should hint at a serious retroperitoneal disease such as renal cell neoplasm. Furthermore, its thrombosis is such an unusual entity that only a few cases have been described. We review the literature and report, to our knowledge, the second case of acute scrotal pain caused by unilateral right-sided varicocele thrombosis complicating an ipsilateral epididymo-orchitis, with no underlying coagulopathy or abdominal neoplasm, to illustrate the clinical, morphologic and therapeutic features of this entity.

Emphysematous prostatitis: A case report.

We report the case of a 48-year-old man with ischemic stroke, diabetes and chronic renal failure admitted for fever with LUTS associated with nausea and vomiting.The physical examination showed a depressible abdomen, painful prostate on digital rectal examination.A biological inflammatory syndrome with diabetic ketoacidosis.The abdominopelvic CT scan confirmed the diagnosis by the presence of gas in the prostate,and the CBUE was positive for Enterobacter cloacae.The patient was treated with appropriate antibiotic therapy with transrectal aspiration of the prostate collection,but the evolution was marked by the worsening of the patient's condition leading to his death after two weeks of treatment.
