DERMATOLOGICA SINICA 32 (2014) 195-196

A 70-year-old man presented with a painless papule on the nail bed of his right third finger, which had been present for 2 years. The patient did not have a history of nail trauma, nor did he have psoriasis or other inflammatory dermatosis. On physical examination there was a 4 × 4 mm erythematous to yellowish subungual keratotic papule with longitudinal splitting of the nail plate and ulceration on the nail bed of the right third finger (Figure 1A). The lesion was tender and firm in texture. Dermoscopy showed keratotic papules with a few dotted vessels at the peripheral area.
