[Testicular epidermoid cyst: A rare entity]. / QUISTE EPIDERMOIDE TESTICULAR: UNA RARA ENTIDAD CLÍNICA.

OBJECTIVE: Testicular epidermoid cyst is a rare clinical entity that accounts for 1% of testicular neoplasias. METHODS AND RESULTS: We report two cases of testicular epidermoid cysts in a 18 and 19 year old males with a painless testicular lesion. Testicular US was carried out showing a hypoechoic nodule in both cases. With the suspicion of testicular neoplasm inguinal orchiectomy was carried out with placement of testicular prostheses in the same act. The pathology report was testicular epidermoid cyst in both cases. CONCLUSIONS: Testicular epidermoid cysts are an uncommon benign entity. When there is a suspicion of this diagnosis, based on tumor markers and ultrasound or MRI images, testicular parenchyma-sparing surgery must be attempted.

Spontaneous hemoperitoneum secondary to retroperitoneal tumor rupture.

OBJECTIVE: To report a case of GIST type retroperitoneal tumor with spontaneous rupture to the abdominal cavity causing acute abdomen secondary to hemoperitoneum. METHODS/RESULTS: We report the case of an 84 year-old man with history of BPH and chronic atrial fibrillation. He presented to the Emergency Department with diffuse abdominal pain, syncope and accompanying vegetative symptoms. Diagnostic work up showed a 19 cm retroperitoneal mass dependent of the left kidney with active bleeding and secondary hemoperitoneum. Left radical nephrectomy was performed with pathology report of gastrointestinal stromal tumor attached to the renal capsule. CONCLUSIONS: Spontaneous hemoperitoneum is a rare entity and it has various etiologies. It is rarely described in retroperitoneal tumors.

Hemoperitoneo espontáneo por rotura de tumor retroperitoneal / Spontaneous hemoperitoneum secondary to retroperitoneal tumor rupture

OBJETIVO: Describimos un caso de tumor retroperitoneal tipo GIST con rotura espontánea a cavidad abdominal, ocasionando un cuadro de abdomen agudo secundario a hemoperitoneo. MÉTODO Y RESULTADOS: Varón de 84 años que acude a servicio de Urgencias de nuestro hospital por cuadro sincopal, con dolor abdominal difuso y cortejo vegetativo acompañante. Tras la realización de diferentes pruebas complementarias se objetiva una masa retroperitoneal de pendiente de riñón izquierdo de unos 19 cm con sangrado activo y hemoperitoneo secundario, por lo que se realiza una nefrectomía radical izquierda con resultado anatomopatológico de tumor estromal gastrointestinal dependiente de la capsula renal. CONCLUSIONES: El hemoperitoneo espontáneo es una entidad poco frecuente y de una etiología variada estando descrita en muy raras ocasiones en tumores retroperitoneales

Urogenital sinus cyst in a 21-year-old man.

We report a case of a rare congenital malformation, a urogenital sinus cyst in a young patient with non-specific symptoms for several months. A 21-year-old male presented with vague and intermittent abdominal pain. Ultrasound scan showed a retrovesical hypoechoic collection (approximately 6 cm) and left renal agenesis, compatible with a possible congenital malformation. These findings were confirmed by MRI. A laparoscopic excision of the cyst was performed with no complications. Pathology report confirmed a urogenital sinus cyst. The postoperative recovery was uneventful and the patient was discharged within 48 h. Urogenital sinus cysts are rare entities with few cases described in the literature. Imaging techniques such as ultrasound, CT or MRI may help with diagnosis. Therapeutic modalities range from observation to needle aspiration or surgical removal. In our case, we chose a laparoscopic approach to minimize morbidity and achieve an early recovery.
