Superficial CD34-Positive Fibroblastic Tumor Treated With Mohs Micrographic Surgery.

Superficial CD34-positive fibroblastic tumor (SCPFT) is a recently characterized mesenchymal neoplasm of the suprafascial tissues. Limited data (21 reported cases) suggest that SCPFT is a contiguous-growth tumor that is infiltrative but circumscribed with a low risk of metastasis. This tumor is characterized histologically by cellular fascicles and sheets of spindled to epithelioid cells. Nuclear pleomorphism is prominent, but mitotic activity is minimal. CD34 is diffusely and strongly positive. All previously reported cases of SCPFT were treated with excision. In this report, the authors describe a new case of SCPFTwith margin control achieved using Mohs micrographic surgery (MMS).
