Epidermis show papillomatosis,acanthosis,hyperkeatosis and basal hypermelanosis.underlying skin has mild perivascular lymphocytic infiltrate with few melanophages. in this area this is suggestive of CARP in proper clinical context. Although, distinction from acanthosis nigricans is not easy for me based on morphology.in fact,some consider it as a variant of acanthosis nigricans according to clinical and histopathological similarity.

Confluent and Reticulated Papillomatosis. It fits enough with age, chest localization and with histological confluent and retiform pattern of thinned epidermis,

Agree with Confluent and reticulated papillomatosis. Clinical and histological pictures fit with this diagnosis.

Confluent and reticulated papillomatosis vs. acanthosis nigricans (probably the first). Can we see PAS stain?
