Would go for metastatic (adeno-) carcinoma first but there was indeed a report of cutaneous presentation of a metastatic pure epithelioid angiosarcoma of the heart mentioned in one of the recent Am J. Dermpathol papers (Am. J. Dermpath. Val-Bernal; 2013;35:286-7; orig. ref: Val Bernal et al J. Cutan. Pathol. 2001;28:265-270). Metastases can also target pre-existing angiomas (not sure if that is the cvase above though).

I favor metastatic adenocarcinoma. I didn't find intracytoplasmatic lumina to consider angiosarcoma. Also, spaces within cellular sheets tend to display round outlines and seem to contain mucoid substance, characteristics of glandular structures, rather than irregular contours and blood-containing, what would make me favor angiosarcoma.

Metastatic prostatic adenocarcinoma . Is it possible to suggest malignant spiradenoma in addition to metastatic adenocarcinoma at HE morphology ?

Dear Dr Rocha, when I said adnexal, I was thinking of apocrine carcinoma ("ductal" carcinoma) and spiradenocarcinoma.
