Multicentric gastrointestinal and extraintestinal leiomyosarcomatosis: a case report.
This article presents a case of synchronous polypoid primary adenocarcinoma of the transverse colon without lymph node or distance metastasis. During the postmortem examination, polypoid smooth muscle tumors in the patient's gastrointestinal tract and extensive extraintestinal smooth muscle tumors in the patient's liver, lungs, and visceral organs, including the diaphragm, parathyroid gland, bone marrow of the vertebrae, and subcutaneous tissue of the left wrist, were reviewed to determine their origin. Histomorphologically, all of the tumors were classified as leiomyosarcomas.
