Abstract

SirClinicopathological classification, diagnosis and management of spitzoid melanocytic lesion present one of the most intriguing issues in dermatopathology. No single clinicopathological feature can offer reliable differentiation of Spitz nevus and melanoma. Although not all the experts agree with the concept of spitzoid neoplasms as a morphobiological spectrum, there is a four‐tiered classification system proposed by Da Forno et al. and encompassing: (i) Spitz nevus; (ii) atypical Spitz nevus; (iii) (atypical) Spitz tumour; (iv) Spitzoid melanoma. It is commonly said that Spitz nevus can show all the ‘local’ dermoscopic features of melanoma, but in a more or less tidy fashion . The occurrence of melanoma‐like dermoscopic pattern in Spitz nevus is also possible. The relationship between dermoscopic and histopathologic atypia is not absolute, in as much as dermoscopically atypical lesions are not necessarily histopathologically atypical as well.A 23‐year‐old female patient presented to our Department due to new, fast‐growing lesion presented as atypical macule on her toe, dark brown colour, which occurred 3 months ago. Her personal and familiar anamneses for skin tumours/melanoma were negative, and she presented with otherwise common nevi count, without any significant dermoscopic atypia. During clinical and dermoscopic evaluation of plantar lesion, lesion had asymmetrical clinical shape
