Acanthosis nigricans: insulin resistance
This is Acanthosis Nigricans.. It is a marker of insulin resistance.. in some cases it may be a marker of internal malignancy as well (not directly a metastatic manifestation, but indicative of underlying malignancy)
yes, i know it was too easy :P. nice point on the internal malignancy!

Acanthosis nigricans is associated with obesity, insulin resistance, type II diabetes mellitus, and certain cancers (gastrointestinal and lung). Lesions are gray-brown to black, rough, with thickened plaques and prominent skin lines occurring in flextural areas (axillae, back and sides of neck, inguinal creases, inframammary). The texture is velvety.
