A 31-year-old woman with a phototype II consulted for this pink tumor on her right thigh. The lesion had enlarged for a couple of months but the patient did not remember exactly when it had occured. Clinical examination was in favor of a Spitz nevus, differential diagnoses included achromic melanoma, clear cell acanthoma, dysplastic nevus.
Dermoscopy revealed dotted vessels and a light brown color at the the periphery. The lesion was excised and pathology revealed a compound melanocytic nevus.
Pink nevi are typicallly found in patients with fair skin type (phototypes I and II). If there are multiple pink lesions, a regular follow-up is advised. If the lesion is solitary as in our case, differentiation from an achromic melanoma is not possible and the lesion has to but excised for pathology.
