Diagnosing an Adenoma with Background of Melanosis

Video Transcription

Video Summary

In this video, the speaker discusses a patient with melanosis coli, a condition caused by long-term use of laxatives of the anthraquinone class. The patient has extensive pigmentation of the colon due to lipofuscin accumulation in macrophages of the lamina propria. The video focuses on a lesion that does not show this pigment uptake and is identified as a conventional tubular adenoma arising in the background of melanosis coli. The video also mentions the pit pattern, which shows thin blood vessels and tubular white structures, indicating a NICE 2 or KUDO 3L pattern consistent with a conventional adenoma. This video tip is sponsored by an educational grant from Braintree, a part of Cibela Pharmaceuticals.
