Hypocellular medallion‐like dermal dendrocyte hamartoma on the abdomen of a 25 year old male

Abstract: Medallion-like dermal dendrocyte hamartoma is a rare congenital lesion that is more commonly seen in females. It often presents at birth on the neck or upper trunk as a well-circumscribed, atrophic patch with wrinkling of the overlying skin. Clinically, the differential diagnosis includes atrophoderma, anetoderma, and congenital atrophic dermatofibrosarcoma protuberans. Histologic findings show epidermal atrophy and dermal spindle cell proliferation that is CD34 positive, along with Factor XIIIa in the origina… Show more

“…7 The main histopathologic differential diagnosis is hypocellular medallion-like dermal dendrocyte hamartoma, also known as CD34 + dermal fibroma. 8,9 This lesion can masquerade as atrophic DFSP with erythematous, atrophic congenital patches. 10 The plaque-like growth features epidermal atrophy and a dermal spindle cell proliferation with CD34 and factor XIIIa expression, mirroring DFSP, but lacking a deeper fascicular compartment or aggressive clinical behavior.…”
