Case Number : Case 2089 - 8 June 2018 Posted By: Dr. Richard Carr

Nodular BCC with amyloid and calcification

Hidradenoma.

Poroid hydradenoma, with some atypical feature. But without any substantial findings of malignancy. 

Pigmented trichoblastoma
 

I opted for BCC because it's recurrent and shows deposits of amyloid and calcification.

I opted for poroid hidradenoma because this tumor looks like a poroma but without epidermal connection ( it’s in essence a poroma ). The necrosis “en masse” is a clue for poroma. 

The bcc shows usually a cleft between epithelium and stroma...here the clefts are stroma-to-dermis

I also thought of poroma family of tumors. If you want to call it poroid hidradenoma it would not bother me, bottom line this looks benign

 hidradenoma

Thanks for the responses. Apologies for delay. I called it a solid cystic (poroid) hidradenoma, focal areas of necrosis, calcification and pigmentation.
