Hyperkeratosis and patchy acanthosis and the typical site... Confluent and reticulated papillomatosis of Gougerot and Carteaud.

I don’t have any knowledge about CRP of Gougerot/Carteaud. Sincerely I was thinking of Dowling/Degos disease. There’s a typical antler like pattern of acanthosis.

Dowling Degos is my first impression

Clinical correlation is needed here. If the patient has lesions in axillae and groins as well, Dowling Degos is likely.

CARP was my initial impression. But this kind of cases require CPC as remarked by the colleagues

Dowling Degos Disease was my first and only thought. The provided history sounds like it too.

I like dowling degos as well. I also considered CRP and acanthosis nigricans. If there is acantholysis, one could also consider Darier disease and Galli-Galli disease. I don't think this is Darier disease but for educational purposes, I thought I would put it out there.

My diagnosis Dowling Degos disease.  I looked for suprabasal acantholysis and could find none.
