  Clinical History Top


A 64-year-old Caucasian man with metastatic melanoma of unknown origin was referred to the dermatology unit in a bid to detect the primary tumour. He had no family history of skin cancer or multiple nevi. Two right axillary lymph node metastatic masses had been discovered, for which an axillary lymphadenectomy had been performed. A positron emission tomography scan was suggestive of malignant nodular lesions in his right lung; biopsy of these lesions confirmed the diagnosis of metastatic melanoma.

During his complete physical examination, a pigmented oral lesion was discovered: a black asymmetric 8-mm homogenous macule located at the right side of the tongue [Figure 1]a. It was asymptomatic and the patient had not noticed it earlier. Dermoscopy imaging showed a structureless, homogeneous, black-bluish asymmetric macule with irregular but well-demarcated borders [Figure 1]b. Biopsy revealed an interstitial accumulation of free black particles with both fibrillar and granular patterns, focally disseminated within the submucosa and surrounding blood vessels. No signs of inflammation or neoplastic processes were seen [Figure 2].
