A case of primary adenocarcinoma of the renal pelvis occurring in a 57-year-old woman who had no previous history is reported. The lesions were thought to be a renal destruction by pyelolithiasis upon symptomatology and imaging study data. A nephrectomy was thus performed. Macroscopic examination revealed voluminous and exophytic lesions surrounding lithiasis. Diagnosis of intestinal-type adenocarcinoma of the renal pelvis was established on histological examination. No evidence of other tumor localization was revealed by complete exploration. Primary adenocarcinoma of renal pelvis is a rare and often mucinous intestinal-type tumour. Chronic inflammation and renal lithiasis seem to be associated with this tumour. Few cases are reported and prognosis is doubtful. The main differential diagnosis to eliminate is secondary lesions to the kidney of adenocarcinoma from another origin. A careful pathological examination in case of pyelonephritic kidney is necessary to look for an associated tumour.  相似文献

Non-trophoblastic placental tumors are rare lesions, either primitive or metastatic, from fetal or maternal origin. We report a case of an intraplacental leiomyoma which was observed in a term stillborn fetus. On the one hand, this observation asks for the origin of this rare tumor, question which can find an answer by molecular cytogenetic and, on the other hand, it deals with obstetrical complications linked to uterine leiomyomas.  相似文献

Papillary fibroelastoma is a benign primitive cardiac tumour, which can be associated with serious embolic complications. We report on a 37-year-old woman admitted for a cerebrovascular accident. Transthoracic and transesophageal echocardiography revealed a small and pedunculated mass attached to the anterior mitral leaflet. Because of the severity of its symptoms and its high embolic potential, the tumour was surgically excised and histologically diagnosed as a papillary fibroelastoma. The postoperative period was uneventful and the patient was discharged at the third day. Papillary fibroelastoma must be surgically treated because of its high embolic potential and its severe prognosis.  相似文献
