RÉSUMÉ
Heterotopic glial nodules of the scalp are non hereditary congenital malformations composed of mature brain tissue isolated from the cranial cavity. The majority of these lesions are found in the nasal region and occur rarely on the scalp. They are frequently diagnosed in newborn infants. However, they may rarely be found in adults. The pathogenesis of these lesions remains unknown. We describe the case of a temporal scalp nodule in a 50 year-old man. At the time of the excision, the mass was not associated with intracranial connection. Histological examination revealed neural tissue staining with S100-protein and the glial fibrillary acidic protein (GFAP).

Squamous cell carcinoma of the gallbladder is rare, accounting for only 0.5-12.7% of all malignant gallbladder tumors. Tumor progression is rapid but silent and therefore usually discovered at an advanced stage, hence its poor prognosis. We report the observation of a 69-year-old woman with known cholelithiasis, admitted for biliary colic. CT scan highlighted a thick-walled gallbladder harboring a tumor invading segments IV and V of the liver. The patient underwent cholecystectomy associated with bisegmental hepatic resection. Pathology showed a well-differentiated, keratinizing squamous cell carcinoma, infiltrating the entire gallbladder wall and the adjacent hepatic parenchyma.

The digestive metastases of uterine leiomyosarcoma are rare. We report a case of a duodenal tumor detected in a 50 year-old woman, 3 years after she underwent a total hysterectomy for uterine leiomyosarcoma. The stenosing duodenal mass was thought to be a mesenchymal tumor. A pancreaticoduodenectomy was performed. The resected lesion was morphologically similar to the uterine leiomyosarcoma. In fact, the histopathological study confirmed a submucosal tumor with typical features of the uterine leiomyosarcoma. Immunohistochemistry was performed and it showed negative CD117 and CD 34. Markers displayed positivity for actin smooth muscle and desmin. Considering the patient history and the immunohistochemical observations, we diagnosed a duodenal metastasis of uterine leiomysarcoma. Through this exceptional observation we want to emphasize the epidemiological and the pathological features of the metastatic uterine leiomyosarcoma. We will also point out the progress of tumoral cells and the histopathological distinctive criteria with a primitive digestive mesenchymal tumor.

Serous cystadenoma of the pancreas is a benign cystic tumor, which radiological diagnosis is easy in its typical microcystic variant. The macrocystic variant is uncommon and raises diagnostic problems with other macrocystic lesions of the pancreas such as pseudocysts and mucinous cystadenomas. We report the case of a young woman with a unilocular macrocystic serous cystadenoma of the pancreas which was identified on pathologic examination of the surgical specimen, after unconclusive abdominal ultrasound and CT-scan. This case describes an unusual clinical presentation of this cystic tumor and emphasizes that the diagnosis of such an entity is still based on pathological examination after cyst removal.

Cystic teratoma of the diaphragm is a rare, generally asymptomatic, disease. We report a case which was disclosed by the development of fever and pain in the left hypochondria. Imaging ruled out surgical emergency and led to the diagnosis, describing the relations of the tumor.

The giant condyloma acuminatum of the perianal region is a tumor characterised by its large size with the propensity to infiltrate into deeper tissues, contrasting with a microscopically benign pattern. The evolution after malignant transformation of condyloma and lymph node invasion is rare. However it is exceptionally observed a lymph node invasion of microscopically benign condyloma acuminatum. The authors report a case of microscopically benign giant condyloma acuminatum of the perianal region associated with inguinal invasion, discovered in a 47 year-old man. Treatment consists in extensive surgery of the tumor and inguinal nodes, followed by a radiation therapy.
