“…Six cases of atrophic pigmented DFSP have been previously described (3,(6)(7)(8) (Table 1). The epidemiology of DFSP has no sex bias (1); the female:male ratio is 4:3 for atrophic pigmented DFSP, which is similar to the ratio of 2:1 for the atrophic variant (3).…”

“…Atypical clinical presentation and morphologic variants such as atrophic and pigmented DFSP may pose challenges for diagnosis (3)(4)(5). Six cases of DPSP with features of the pigmented and atrophic variants have been reported to date (3,(6)(7)(8). Here we report a new case of DFSP with features of pigmented and atrophic DFSP, and review the six published cases.…”

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma characterized by the proliferation of spindle cells arranged in a storiform pattern. Here we report a case of DFSP presenting as a bluish-black atrophic plaque. The tumor had the histopathologic characteristics of both the pigmented and atrophic variants of DFSP. We describe the histopathologic, molecular, and imaging features of this patient and review other cases of DFSP that have been reported in the literature. Early identification of this DFSP variant can help clinicians implement clinical management strategies to prevent recurrence.

“…So far, seven cases of atrophic pigmented dermatofibrosarcoma protuberans in addition to ours have been reported in PubMed, all presenting with a depressed pigmented plaque, three of which developed a nodule within the plaque [Table 1]. 4,[7][8][9][10] Due to their atypical presentations, various incorrect diagnoses were considered, including lipoatrophy, hemangioma and neurofibroma. 4,9 In our case, misdiagnosis of hyperpigmentation was made at initial visiting and only observation was recommended.…”
