Colonic lipomas are rare benign neoplasms; approximately 10% present as multiple lesions. The prevalence is equal in both men and women, presenting usually as asymptomatic lesions, which are diagnosed incidentally. However, when they are large (> 2cm) they may present with abdominal pain, intestinal obstruction, rectal bleeding or altered bowel habits. We report on a 78 years old female patient with a 12 months history of changing bowel habits characterized by constipation, diffuse colic abdominal pain, and weight loss associated with hiporexia. Her laboratory tests report eosinophilia: 21% of 9600/mm3 WBC, hemoglobin 10.9 g/dl, hematocrit 38.6%, stool tests were normal. Serology for toxocariasis was positive. Upper gastrointestinal endoscopy revealed hiatal hernia and erythematous gastric mucosa; biopsy was compatible with chronic atrophic gastritis. Colonoscopy revealed 5 raised lesions between 3 and 5cm in diameter, round, pendulous, covered with normal-appearing yellowish mucosa, ("pad sign"). This distribution in the transverse, descending and sigmoid colon is suggestive of lipomas coexisting with sigmoid diverticulosis. Treatment was indicated: osmotic laxative and anti-parasitic medications with symptomatic improvement. Currently the patient has 12g/dl of hemoglobin, and 3% eosinophils with normalization of her bowel movements.
