Background Leiomyosarcoma of the inferior vena cava (IVC) is a rare tumor that develops from the wall of the IVC and can be confused with many other retroperitoneal tumors. We report the observation of a man with leiomyosarcoma of the vena cava which invades the right kidney. Case presentation 56-year-old man who has seen progress for right back pain for over a year. His thoraco-abdominal-pelvic scanner found a right tumor process measuring 18 × 13 × 18 cm invading the right kidney and the inferior vena cava, heterogeneous in nature, which is enhanced after injection of iodinated contrast product, pushing back the liver and the gall bladder. A border of separation persisted between the mass and the abdominal and thoracic walls. His biological assessment was normal. He underwent an open right nephrectomy with intraoperative bleeding requiring a transfusion of 2 red blood cells. The patient's follow-up period was 8 months without local recurrence or secondary localization. Conclusion The LMS of IVC is a tumor whose management is not yet well codified. Surgery is the only therapeutic means that gives good results, when it is possible. But long-term recurrences remain frequent, which therefore requires prolonged monitoring of these patients.
Background Granular cell tumors (GCTs) also called Abrikossoff's tumor are rare tumors of often benign neurogenic origin, mainly located in the craniocervical region, rarely found in the external genitals. We report in this article the case report of a purely cutaneous case of rare clinical presentation at the level of the penis. Case presentation We report the case of a man, aged 54, with no history, consulted for a nodular lesion on the penis evolving for a year. a nodular cutaneous plate, indurated 3 cm in large diameter, painless and mobile in relation to the deep plane. The lymph node areas were free, and the remainder of the skin examination was without abnormalities. Conclusions Granular cell tumors (GCTs) also called Abrikossoff's tumor are rare tumors of often benign neurogenic origin, mainly located in the craniocervical region, rarely found in the external genitalia, the diagnosis is based on anatomopathology study completed by immunohistochemistry, and treatment consists of complete surgical excision of the tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
