Dysplastic Nevus Syndrome Associated with Melanoma in a 45-Year-Old Patient

Abstract

A 45-year-old patient with dysplastic nevus syndrome and a history of previously excised melanoma was referred for a regular mole examination. Six dysplastic nevi had been previously excised, and two years earlier, a superficial spreading melanoma with the nodular component, Breslow thickness 2.9 mm was excised. During a full body examination, a clinically suspicious pigmented lesion was detected on the left suprascapular region. The lesion was highly pigmented, 1.5 × 1.2 cm in diameter, composed of a flat and a nodular component. Dermoscopic examination revealed atypical prominent pigmented network associated with whitish lines on the elevated part of the lesion, suggesting one more invasive melanoma. The patient was referred to a plastic surgeon for surgical excision and pathohistological examination, which revealed superficial spreading melanoma with the nodular component, Breslow thickness 2.6 mm.
