Answer: Desmoplastic trichoepithelioma
Histology: The sections show a proliferation of small angulated epitheliel islands and strands of basaloid epithelium with keratinecous cyts formation and associated sclerotic stroma. These demonstrate ductal differentiation, with “tad pole” epithelial extends.
Discussion: This lesion demonstrates overlapping features with syringoma and microcystic adnexal carcinoma, but the process extends and appears to be limited to the lower reticular dermis, favoring desmoplastic trichoepithelioma. A conservative excision with negative surgical margins is the treatment of choice.
