The third image clearly shows poroid and cuticular cells. I thought of this as a poroma showing combined patterns; classic poroma pattern and dermal duct tumor pattern. Although last image shows mild pleomorphism, I do not think it is enough to consider malignant transformation, but I am not 100% sure. May be I will carry some proliferative markers.

Difficult and would like to see glass but favour a low-grade ductal carcinoma (probably primary cutaneous). DDx was dermal duct tumour but extent, profile and mild cellular atypia probably warrant a low grade carcinoma requiring complete excision with clear margins (margins here are quite close). Ducts / glands looks slightly apocrine in areas.
