Diffuse colonic lipomatosis with giant hypertrophy of the epiploic appendices and diverticulosis of the colon

Abstract

Of the 12 cases of colonic lipomatosis previously reported, only 2 have isolated involvement of the entire organ, but they do not present lipomatosis of the epiploic appendices.

Diffuse Colonic Lipomatosis, Presenting as Perforation Peritonitis and Mimicking Carcinoma Colon

“…In colonic lipomatosis, there are lobules of mature, unencapsulated adipose tissue lying clumped in the submucosa of the colon and it may be segmental lipomatosis in which such lobules lie in a single segment of colon [1]. 10 cases of segmental lipomatosis have been described by Catania et al [1].…”

“…diffuse lipomatosis the lobules of adipose tissue are present in the submucosa of whole of the colon. Only four cases of this type have been reported in literature [1,4,5,7].…”

“…Lipomatous lesions of the colon may be solitary or multiple, encapsulated lipomas or diffuse, discrete, unencapsulated lobules of adipose tissue, called lipomatosis and though they are second most common benign tumours of the colon, they are infrequently encountered in clinical practice [1,2]. A patient of diffuse colonic lipomatosis, presenting as perforation peritonitis and presumptively diagnosed as carcinoma colon during surgery is presented.…”

Intussuscepção intermitente de lipoma de cólon transverso

“…A maioria localiza-se no espaço submucoso, podendo acometer também o subseroso e os apêndices epiplóicos 1,2 . Sua incidência aumenta após os 50 anos e em aproximadamente 80 % dos casos é único.…”

“…Quando esses tumores são maiores que 4cm de diâmetro, produzem sintomas em mais de 75% dos doentes, tais como: dor abdominal tipo cólica, mudança de hábito intestinal, massa palpável e perda de peso, dor abdominal vaga, sangramento pelo ânus ou anemia e menos freqüentemente, sintomas e sinal de obstrução, ocasionados pelo próprio lipoma ou quando este apresenta como a "cabeça" de uma intussuscepção 1,2,3 . A intussuscepção é a complicação mais freqüente do lipoma submucoso 1,3 , como ocorreu no nosso caso.…”
