Adenomyoma is a benign tumor composed of endometrial glands, specialized endometrioid stroma, and smooth muscle. These tumors typically originate within the uterus. An extrauterine adenomyoma is an extremely rare entity. We present the case of a 56-year-old perimenopausal woman with a right adnexal mass, diagnosed histopathologically as an ovarian ligament adenomyoma. This report documents a fourth case of an extrauterine adenomyoma and only the second case in ovarian ligament. The differential diagnosis includes endometrioma, leiomyomatosis peritonealis disseminata, uterus-like mass lesion and extrauterine leiomyoma with entrapped endometrioid glands and stroma. Two theories for the etiology of adenomyoma have been proposed: (i) Müllerian duct fusion defect and (ii) metaplasia.
Cysticercosis, infestation with the encysted larval stage of Taenia solium, is a major health problem in most countries of Latin America, Asia, and Africa. It involves mainly the central nervous system. Muscle involvement is also seen, although it usually remains asymptomatic. Solitary intramuscular cysticercosis, without involvement of central nervous system is a rare entity. We present two cases of solitary intramuscular cysticercosis, without any systemic or neurologic manifestations.
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.
