Schwannoma of the adrenal gland is extremely rare. Here, we report a 49-year-old patient with an adrenal tumor noted incidentally by abdominal ultrasonography while undergoing regular health examination. Retroperitoneal laparoscopic adrenalectomy was performed and the schwannoma was diagnosed by histologic findings and immunohistochemistry. Five months after surgery, the patient remained well and without evidence of recurrence or metastasis.
The simultaneous occurrence of renal collecting duct (Bellini duct) carcinoma and bladder urothelial carcinoma is very rare. A 68-year-old female patient with bladder urothelial carcinoma first received transurethral resection of the tumor. Left side nephrouretectomy and transurethral resection of the intramural ureter were performed 8 months later under the diagnosis of concomitant renal pelvic urothelial carcinoma. However, the final pathologic examination revealed collecting duct carcinoma. The patient received systemic chemotherapy after surgery, but distant metastasis was noted 6 months later. Here, we report a rare case of combined renal collecting duct carcinoma and bladder urothelial carcinoma confirmed by pathologic examination and immunohistochemical staining.
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.
