Giant villous adenoma in an incarcerated rectal prolapse: A clinical conundrum!
نویسندگان
چکیده
Rectal prolapse is a distressing condition associated with incontinence. However, incarcerated rectal prolapse is a rather rare entity. We had a 75-year-old man with irreducible rectal prolapse who required recto-perineal sigmoidectomy (Altemeier’s procedure) after failure of initial conservative treatment. Histology showed rectal tubulo villous adenoma with moderate to severe dysplasia. This case is unusual as it is a rare combination of irreducible rectal prolapse, which appears to have been caused by a large neoplastic change. Rectal prolapse represents full-thickness protrusion of the rectum through the anal sphincter mechanism. Rarely, the prolapsed portion of the rectum can become incarcerated or even strangulated. The exact incidence of rectal prolapse although unknown, it is a rather rare entity. We hereby report a case of a rectal prolapse with incarceration and neoplastic change.

متن کاملA giant villous adenoma: case mimicking rectosigmoid malignancy; radiological survey to diagnosis.
Villous adenomas are benign lesions, which are difficult to interpret because of their malignancy potential. They have similar radiological findings to malignant lesions. Usually, villous adenomas are asymptomatic although they may cause rectal bleeding like malignant tumours. We present a case of giant villous adenoma to evaluate the contribution of its radiological features including double c...

Degenerate hypersecretory villous adenoma of the rectum is an uncommon, life-threatening condition. Its diagnosis is clinically challenging since cardinal symptoms are neurological and metabolic in nature because of significant fluid and electrolyte disorders induced by severe diarrhea. Even though the condition was first described back in 1954 its pathophysiology remains unknown. Management is...

BACKGROUND The authors present a woman suffering from McKittrick-Wheelock syndrome (MKWS) with a giant rectal villous adenoma. MKWS is a rare disorder caused by fluid and electrolyte hypersecretion from a rectal tumor. The most frequently reported tumors are villous adenomas. Symptoms of dehydration with severe hyponatremia, hypokalemia, metabolic acidosis and acute renal failure are typical in...
