Problems of Suitability Laser’s Excision of Pigmented Dermal Lesions: Case Report of Minimal Deviation Melanoma

Overview

The paper describes a case of a 23-year-old woman, in whom an intradermal pigmented nevus was removed by an excision using a CO₂ laser. In histological examination a minimal deviation melanoma (MDM) was found, occurring sparsely in the centre of the nevus. A sufficiently wide excision is important not only in terms of the pathologist who assesses the lesion but also, in particular, in terms of the prognosis to the patient. In problematic diagnoses where it is necessary to assess the extent of the lesion as well as its edges and base in particular, the sample taken by laser may be insufficient. The authors report widely used methods of nevus laser surgery and highlight the necessity of a sufficiently radical exstirpation of a nevus.
