Abstract
A 63-year-old female visited our hospital because of positive occult blood in stool. Endoscopic and barium enema studies demonstrated multiple flat elevated lesions with small conglomerated nodular surface (nodule-aggregating lesion) in the ascending, transvers and descending colon. Total six nodule-aggregating lesions were detected in the colon, and the avarage size of the lesions was 31±14 mm in diameter (ranged 17-55 mm in diameter) .
Strip biopsy was performed to one of the lesions in the transverse colon, and histological examination revealed tubular adenoma with moderate atypia. And other lesions were diagnosed tubular adenoma with mild and moderate atypia by biopsied specimen histologically.
In our knowledge, there have been few case reports of multiple nodular-aggrregating lesions of the colon such as in this case.
