Mixed tumor of the skin with prominent myoepithelial component. There is some nuclear hyperchromasia but could not find atypical mitotic activity... The lesion is well circumscribed... I think it is benign.

Solid-cystic hidradenoma composed of squamoid and oxyphilic cells, embedded in sclerotic stroma, best seen in the center of the lesion.

This is a hyaline cell rich-apocrine mixed tumour (without any identifiable typical chondromyxoid stroma). I appreciate this is a bit semantic in distinction from hidradenoma but I thought you might like to see this hyaline cell rich variant which I must admit I had not appreciated before. The case was seen by Dr Kazakov.
Enjoy your weekends.

Mixed tumor is probably the correct diagnosis, but in I would also run neuroendocrine markers to rule out endocrine mucin producing sweat gland carcinoma.
