RESUMO
The presence of ectopic splenic tissue in the scrotum is attributed to splenogonadal fusion, a rare congenital anomaly. This ectopic splenic tissue can be an incidental finding or less often present as a scrotal mass later in adult life. Given the rarity of splenogonadal fusion, especially in the adult population, this case highlights the clinical characteristics of the condition, with a special focus on the signs and findings that might help prevent unnecessary orchiectomy.

Malignant tumors of peripheral nerves (MPNST) represent approximately 5-10% of all soft tissue sarcomas and usually are in relationship with a major nerve. Primary cervical malignant Schwannomas are very rare neural sheat tumors that, grossly and clinically, are misdiagnosed for other more frequent lesions of the uterine cervix. We report a case of primary cervical malignant Schwannoma in a 27 years old female with atypical bleeding. The lesion is characterized by densely packed spindle cells with nuclear atypia and high mitotic rate. Immuno-histochemical stains are positive for vimentin and S-100 but negative for HMB-45, keratins, desmin and actin. After 34 months the patient is disease free. To our knowledge, this is the seventh case described.

Pacinian neuroma is an extremely rare benign tumor which has only occasionally been reported in the literature. To date, this lesion has usually been observed in the hand and foot; only one had intra-abdominal localization. Local trauma is reported in the most of these cases. We describe the first case of retroperitoneal pacinian neuroma. The lesion was observed as an incidental finding in a 75-year-old man who underwent laparotomy for aortic aneurysm. Here are discussed the differential diagnosis and a complete literature review on the topic.

Gastrointestinal angiodysplasia is an acquired and degenerative lesion characterized by proliferation and ectasias of the vessels of the mucosa and submucosa. It's thought to be one of the most common causes of lower gastrointestinal bleeding in the elderly. We describe two cases of angiodysplasia and review the related literature.
