Leiomyosarcoma of the colon: a case report and review of literature

Diseases of the Colon and Rectum
B K RaoS Roy

Abstract

Leiomyosarcoma of the colon, excluding that of the rectum, is extremely rare. We report a case of leiomyosarcoma of the ascending colon with a brief review of literature. The clinical manifestations in our case were typical: abdominal pain, diarrhea, anorexia, and a palpable tumor that was firm, smooth, and mobile inspite of its bulk. Toxic features, cachexia and weight loss were less prominent. Morphologically the tumor was of dumbbell type with intracolic and extracolic components. The microscopic picture, consisting of spindle-shaped smooth-muscle cells with pleomorphism and one to three mitotic figures per high-power field, was characteristic. In the absence of local spread, a hemicolectomy was considered curative, but our patient developed extensive metastasis in 25 months. The correlation between mitotic activity of the tumor and prognosis in our case was consistent with that reported in literature.

Anorexia Nervosa

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. Here is the latest research on AN.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
