Agree With tubular apocrine adenoma, associated with sebaceus nevus

Yes, tubular adenoma first thought too. Interestingly, there is focal epidermal connection on the right side in 1st 2 low power images, with transition from glandular epithelium to squamous epithelium. SCAP with predominant intradermal component can look identical to tubular adenoma. There is an interesting discussion on this issue on Pg 75-77 of Kazakov textbook.

Yes. There is some verrucous change in the surface epidermis too.

We also thought an adnexal tumor associated with nevus sebaceus and syringocystadenoma papilleferum. This was a 3-4 mm punch biopsy of a larger lesion so we asked that the lesion  be excised given the age of the patient. On re excision the lesion was focally infiltrative so we asked for a second opinion from Tim McCalmont. His final diagnosis was apocrine carcinoma, given the infiltrative nature of the lesion (although that finding was subtle). Final diagnosis: apocrine carcinoma.

Agree with adenoma on these images (presumed naevus sebaceous).
