I don’t feel it is plexiform fibrohistiocytic tumor. Myxoid component is not present in this tumor and circumscribedness is not a feature of it which, conversely, emanates tentacle-like extensions into the subcutaneous fat as a typical characteristic.
I go with cellular neurothekeoma.

[font=tahoma,geneva,sans-serif][size=4]I agree this resembles cellular neurothekeoma, given overall good circumscription, internal whorled nodular architecture, and especially the variable, focally extensive mucinous stroma; there is absence of significant pigmentation, vascular stroma, hemorrhage, or fibrosis. The cells are large, oval to spindled with frequent osteoclast-like multinucleation, and absence of pleomorphism or high-grade atypia.
I am concerned, however, by the moderate mitotic activity with aberrant spindles. Staining may be helpful.[/size][/font]

I agree this could represent cellular neurothekeoma, although according to Dr. Miettinen's book location at the hands and feet is distinctly uncommon. In my opinion, another possibility is nodular fasciitis. The irregular tears in the tissue containing mucin, the non-atypical spindle cells and the presence of osteoclast giant cells suggest this diagnosis, although location in the dermis is also very uncommon.

I called this cellular neurothekeoma.
