Malignant transformation of a mature retroperitoneal teratoma into adenocarcinoma.

Retroperitoneal mature teratoma is a rare congenital tumor, far behind ovarian and testicular localizations. Malignant transformation of teratomas is extremely uncommon. We report a case of a 23-year-old female, who presented with chronic pelvic heaviness, abdominopelvic ultrasound revealed a cystic mass in the right iliac fossa, initially considered as a functional ovarian cyst. Given the persistence of the patient's symptoms a pelvic MRI was requested. It showed a right retro-colic cystic unilocular with parietal nodule. The two ovaries showed normal appearance. A retroperitoneal teratoma was suggested given the retroperitoneal topography of the mass, and the presence of a tissular parietal nodule. She underwent surgery and the diagnosis was confirmed after histological study.

Atypical manifestation of a fistula between a hydatid cyst of a liver and a gallbladder: A case report.

The hydatid cyst of the liver is the most common location of hydatid disease. Complications in this form are dominated by superinfection of the cyst and rupture into the bile ducts or the peritoneal cavity. We report the case of a 54-year-old female patient with a hydatid cyst of the liver complicated by a rupture in the gallbladder revealed by urinary symptoms.

Breast tuberculosis: A forgotten diagnosis.

Breast tuberculosis is a rare entity even in endemic countries. It is often considered as a diagnostic conundrum given the non-specific clinical and imaging characteristics. Therefore, the definitive diagnosis is based on the identification of bacilli by microbiological or histopathological examination. We report the case of a 52-year-old woman, with a 2-month history of a painful lump of the left breast. The imaging features were consistent with a breast abscess. The purulent collection was aspirated and a tuberculous mammary abscess was diagnosed by molecular biology (GeneXpert). Through this observation, we discuss the clinical, radiological and biological signs by highlighting the contribution of molecular biology in the rapid management of this rare pathology.

[Paratesticular rhabdomyosarcoma. A case report]. / Rhabdomyosarcome paratesticulaire. A propos d'un cas.

The rhabdomyosarcomas are rare tumors of mesenchymal tIssue. Whose most frequent localisations are génito-urinary, and occur in the child and young adult. It's an intrascrotal tumour, localised in the tunica vaginalis, epididymis or spermatic cord. The Authors report a case of paratesticular rhabdomyosarcoma in a 15 Year old child, who presented a right painless scrotal mass since two Months. The research of the tumoral markers is negative. Scrotal ultrasound shows a tissular mass in spermatic cord. Abdominal ultrasound and CT show retroperitoneal lymph node mass. Chest X-ray is normal. The intervention consists of a right castration. The histological examination of the spiceman confirms the diagnosis of the paratesticular rhabdomyosarcoma of the spermatic cord. The patient is treated by chemotherapy without improvement. Through this observation, the Authors underline the interest of the imagery and the aspects of the paratesticular tumours in ultrasound and CT.
