According to the history, this skin lesion was present since birth as a macroscopically solid, asymptomatic and painless nodule that slowly increased in size, measuring -before excision- about 0.8 mm in diameter (Figure 1).
Histologic features: elongated neoplastic cells arranged in interconnected fascicles with a plexiform pattern (A). Ovoid and round neoplastic cells intermixed with osteoclast-like giant cells and hemosiderin deposition (B). (A: hematoxylin-eosin, x100, B: hematoxylin-eosin, x200)
