A 52-year-old woman consulted for an atypical pigmented lesion on her right thigh.
Dermoscopy revealed:
- asymmetry
- eccentric pigmentation
- atypical reticular network
- depigmentation
- pink/red area
Clinical and dermoscopic images were in favor of a melanoma.
Lesion was excised and pathology revealed a dermatofibroma.
This case is interesting to show how a dermatofibroma may be atypical:
- clinical examination: no induration at palpation and asymmetry of colours
- dermoscopic features
