Plaque-type multinucleate cell angiohistiocytoma.
BACKGROUND
Multinucleate cell angiohistiocytoma (MCAH) is a rare cutaneous disorder that usually presents as papules or nodules.


OBJECTIVE
This article reports a case of MCAH that appeared clinically as a large cutaneous plaque.


RESULTS
A 74-year-old woman presented with a large painless, dusky red, indurated plaque measuring 12 x 6 cm on the trunk that was found on histopathologic examination to be a MCAH. Based on a literature review, this is the first reported case of MCAH presenting as a plaque rather than a papule or nodule.


CONCLUSIONS
Multinucleate cell angiohistiocytoma may manifest clinically as a solitary cutaneous plaque.
