Parasitic Leiomyoma (PL) is considered a rare variant of uterine fibroids occurring outside the uterus. We hereby report a challenging case of parasitic leiomyoma that is considered rare in the literature with all its particularities. A 62 YO lady is known to have a history of diabetes, right breast carcinoma, appendectomy and normal vaginal deliveries presenting with a two-year history of back and abdominal pain with recent urinary symptoms. Therefore, an abdominopelvic Ct scan and MRI were done showing uterine fibroids compressing the bladder. The patient underwent an exploratory laparotomy. A palpable intravesical mass was identified. Transurethral cystoscopic resection was performed. Pathology results confirmed the leiomyomatous nature of the mass. Postoperatively, the surgery was complicated with a wound dehiscence and a hematoma formation on the left lateral wall of the bladder that was treated conservatively with a good follow-up outcome.
Mucinous cystic neoplasms (MCNs) are uncommon cystic lesions that arise in the liver and biliary system (MCN-LBS) and the pancreas (MCN-P) and rarely arise from the extrahepatic biliary system. Histologically, these lesions are defined by the presence of variably mucin-producing epithelium with ovarian-like, hypercellular mesenchymal stroma. Herein, we present a case of extrahepatic MCN-LBS in a 51-year-old woman. This lesion arose from the cystic duct and was removed via laparoscopic cholecystectomy. Histologic examination confirmed the diagnosis. To our knowledge, this is the third case report of an MCN-LBS arising from the cystic duct in the English literature. In this article, we review clinical and histologic characteristics of MCNs and present two other reports of MCN-LBS of the cystic duct.
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.
