Mycobacterium chelonae infection in a patient being treated with adalimumab.

Myxoid DFSP expresses apolipoprotein D and presents with a storiform pattern and characteristic subcutaneous infiltration. Diagnosis is confirmed by detection of the chromosomal translocation t(17;22). The differential diagnosis should include benign myxoid lesions with spindle-shaped cells (myxoid neurofibroma, superficial angiomyxoma, mucous cyst), malignant myxoid lesions with spindle-shaped cells (myxoid DFSPM, acral myxoinflammatory fibroblastic sarcoma, low-grade fibromyxoid sarcoma, myxofibrosarcoma), and other acral neoplasms such as sclerosing perineurioma, periungual fibroma, digital fibrokeratoma, and cellular digital fibroma. This last entity is composed of spindle-shaped CD34-immunoreactive cells and can be distinguished from SAF as it is less myxoid and more cellular, although several 11 copathological study of new 41 cases from the U.K.: should myxoma (NOS) and fibroma (NOS) continue as part of 21stcentury reporting?
