Two Cases of Unusual Abscesses in Right Colon Cancer

ABSTRACT

Two unusual presentations of carcinoma of the right colon are described. One of the two patients presented with huge abdominal abscess with adhesed to surrounding small bowels and the other presented with anterior abdominal wall abscess. Colonic carcinoma very rarely presents as abdominal wall abscess, retropertoneal abscess, groin inflammatory mass, subcutaneous thigh abscess, and obstruction with diastatic rupture of cecum. The appearance of the abscess may antecede any gastrointestinal symptoms, thus lessening the surgeon's suspicion of carcinoma. The literature has been reviewed and the pathology that characterizes such lesions and this management is discussed. The bulky colonic tumors with extensive local invasion and negative mesenteric lymph nodes have a relatively good prognosis if adequate resection is performed.
