Biopsy was taken which suggested fatty tissue. The CECT of abdomen confirmed the colo-colic intussusception with lipoma as a lead point. Intra-operatively a large lipoma from the descending colon had caused the colo-colic intussusception (Figure 3). The patient underwent a left colectomy with stapled colo-colic anastomosis. Histopathological examination confirmed the lipoma.The third case was a 73-year-old lady who presented with subacute intestinal obstruction. Clinically, the abdomen was soft and distended. Digital rectal examination revealed a large mass occupying the whole of the rectum. Sigmoidoscopy showed a large ball-like mass with ulcerated surface. The CECT of abdomen revealed a thick walled rectum and sigmoid colon with soft tissue density lesion in the recto-sigmoid junction causing luminal narrowing. At surgery, there was a large polypoidal mass arising from the sigmoid colon and causing a colo-rectal intussusception (Figure 4). Sigmoid colectomy with colo-rectal anastomosis was done. The patient recovered uneventfully. Histopathological examination revealed colonic lipoma.
DISCUSSIONBauer first described lipoma of the colon in 1757.4 These lipomas occur in elderly people (average age 60 years).3 In our series of three cases, one was young at 23 years of age while the other two presented were above 50 years of age. Almost 70% of these lipomas are localised in the right hemi-colon; the caecum, ascending and transverse colon in decreasing order of
Aggressive angiomyxoma (AA) is an uncommon tumor occurring in females and is rarely reported in males with propensity to recur. Due to its presence in perineal and genital region, it has to be differentiated from other myxoid neoplasms. The tumor expresses estrogen and progesterone receptors, which may have a role to play in tumor therapy. Wide local excision remains the mainstay of the treatment. We present a case of AA excised from left spermatic cord.
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.
