1/6. Splenogonadal fusion: report of a case and review of the literature.We report a case of splenogonadal fusion masquerading as a testicular tumor and review the etiology, the pathogenesis and the management of this rare disease. A 20-year-old male patient presented with clinical and radiological findings of a left testicular mass for which he underwent a left radical inguinal orchidectomy. Histopathology of the removed testicle revealed no tumor. The gonad was fused to ectopic splenic tissue, the later forming a distinct encapsulated mass attached to the lower pole of the testicle inside the tunica vaginalis. Splenogonadal fusion, although a rare condition, may account for a non-malignant testicular mass and should be suspected in young patients with other congenital anomalies.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/6. A case of fibrous pseudotumor originating from tunica vaginalis testis.A 32-year-old man presented with a complaint of painless palpable mass of the left scrotal content. Based on the preoperative diagnosis of scrotal or spermatic cordal benign tumor, local excision was performed. The histological diagnosis was scrotal fibrous pseudotumor. In japan, only 35 cases of fibrous pseudotumor of the scrotum have been reported including our case. orchiectomy was performed in 15 cases. Fibrous pseudotumor is a benign fibroproliferative lesion with dense hyalinization and sometimes focal calcification. It may be induced by previous intrascrotal inflammatory events such as epididymitis, an infected hydrocele, prior surgery or trauma. Although a relatively rare disease, a fibrous pseudotumor should be considered in the differential diagnosis of testicular and testicular tunica tumors. Our case was of a benign pseudotumor and orchiectomy could have been avoided.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/6. Spontaneous intratesticular haemorrhage.Spontaneous intratesticular haemorrhage is a rare disease. Four cases have been described, all diagnosed after orchidectomy. We present an additional patient with a spontaneously arisen intratesticular haematoma in whom orchidectomy could be avoided.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/6. Alveolar echinococcosis with involvement of the ureter and testis.Alveolar echinococcosis is a rare disease of the liver, and occasionally of the lungs and brain, that is endemic across areas of Central europe, the Soviet Union and alaska. We describe a case of alveolar echinococcosis with involvement of the ureter and testis overshadowing the liver manifestation. The unusual presentation and nondemonstrable exposure to the organism caused misinterpretation of the histological findings and an initial misdiagnosis of tuberculosis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/6. polyarteritis nodosa of the epididymis in a patient with Whipple's disease.The case of a 55-year-old white male who developed necrotizing arteritis localized to the superior pole of the epididymis is presented. He had a history of Whipple's disease and euthyroid Graves' disease. Histopathologic section of an extratesticular mass showed a necrotizing vasculitis with giant cells; periodic acid Schiff stain for Whipple "bacilli" was negative. The combination of rare diseases in our patient suggests the possibility of a common infectious or immune etiology, perhaps mediated via circulating immune complexes.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/6. Pulmonary alveolar microlithiasis associated with calcifications in the seminal vesicles.Pulmonary alveolar microlithiasis is an inherited disorder of unknown etiology. It is a rare disease characterized by calcified intraalveolar microgranules. Several hypotheses on the etiopathogenesis have been put forward, such as increased intestinal calcium resorption and retention. This case report of pulmonary alveolar microlithiasis is associated with punctate calcifications in the seminal vesicles.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
