摘要
Dermatofibroma is a firm, skin-colored or reddish-brown sessile papule or nodule. It arises spontaneously without a known cause or after a minor trauma, such as an insect bite. A 39-year-old Asian woman complained of a palpable mass and tenderness in the right upper eyelid. On physical examination, a firm palpable subcutaneous mass was detected in the upper eyelid. Surgical exploration under local anesthesia showed a fibrotic and firmly attached mass to the tarsal plate. In histopathologic examination, the mass was characterized by a fibroblast proliferation in the dermis with an overlying hyperplastic epidermis with frequent basal hyperpigmentation. As far as we know, there have been no previous reports of dermatofibroma located on the tarsal plate. This article is a good example for intratarsal location of dermatofibroma.
