Leiomyosarcoma of the extremities is an unusual tumor. Herein we report a unique and what we believe is the first case of a patient in whom there was complete disappearance of such a tumor following regional hyperthermia and chemotherapy.
The term bezoar refers to a foreign object found like a mass of concretion in the gastrointestinal tract that results from an accumulation of undigested material. When the composition of the ingested material is a medication, it is known as a pharmacobezoar. A rare complication from pharmacobezoar is large intestinal obstruction. Here we present the case of a 77-year-old male who presented with progressive abdominal distension, involuntary guarding, and large bowel obstruction. Abdominal imaging studies were remarkable for radiopaque objects of uncertain etiology in the transverse colon and rectal ampulla. The patient underwent colonic decompression by sigmoidoscopy, where the pills were identified by direct visualization. He later underwent endoscopic removal of the pharmacobezoars. A detailed medication review identified the culprit to be multivitamins. This case portrays an unusual etiology of large bowel obstruction. At this moment, no cases have been reported of multivitamins as the culprit of pharmacobezoar with subsequent development of large bowel obstruction.
This paper presents an overview of recent developments pertaining to colorectal adenocarcinoma. It is aimed toward the practicing clinician. Topics discussed include epidemiologic observations; genetic predispositions; molecular biology findings; screening and early detection programs; endoscopy; principles of surgical resection; laser and radioimmunoguided surgery; staging; selection of patients for adjuvant chemotherapy; and considerations regarding biologic response modifiers and pain control in the advanced-disease setting.
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.
