This biopsy was taken from a female patient with age over 40, presenting with red papules on her legs and/or hands. My histologic diagnosis is multinucleate cell angiohistiocytoma.

I favor multinucleate cell angiohistiocytoma. Mast cells are not prominent in this case.

Multinucleate cell angiohistiocytoma. Geometric-shaped multinucleated cells and dilated vascular spaces are characteristic.

Seems like there is a consensus. Would be stupid for me to disagree on this spotter.

Yes no tricks from me today. I called the multinucleate cell angiohistiocytoma and I did not think you needed the history which proved correct but for the record:
M75. Dorsum L hand. ?Dermatofibroma ?scar tissue. 6 mm punch excision.
Enjoy your weekends and the festive season!!!!
