Case Presentation                                                       Teaching point
A 12-year-old boy presented with a 1-year history of slowly             Atrophic dermatofibroma is a rare variant of dermato-
growing, 1,5 cm x 2 cm, livedoid, hard and depressed livedoid           fibroma which was first described by Page and Assaad in
lesion on his back (Figure 1, A and B). Dermoscopic evalu-              1987 [1]. It is commonly seen on the upper back of mid-
ation showed homogenous gray-whitish and livedoid large                 dle-aged women, and the mean age of the patients affected
clods and crystalline structures (Figure 1C). The patient was           is 49.7 years, according to literature [1]. We present this
referred for total excision. Histologically, fibro-histiocytic          uncommon entity, which is in the differential diagnosis with
benign tumoral lesion located in a dense collagenized                   many benign and malignant lesions including atrophic scars,
stroma separated from the epidermis by a cell-poor zone                 anetodermas, morphea, atrophic dermatofibrosarcoma pro-
was observed. A few scattered lymphocytes were observed in              tuberans and sclerosing basal cell carcinomas, as it is rare in
between (Figure 1, D and E).                                            the pediatric age group [2].
