Abstract

Background: Data on the dermoscopic features of fungal melanonychia are limited.

Aim: To identify the dermoscopic features of fungal melanonychia.

Methods: We reviewed patient files, clinical history and dermoscopic images of all cases with a diagnosis of fungal melanonychia seen at our dermoscopy unit within the past year.

Results: In total, 14 cases with 20 involved nails were reviewed. The most common type of melanonychia was melanonychia striata (7/20). Multicoloured pigmentation was observed in 19 of the nails. The main dermoscopic pattern was homogeneous pigmentation; however, black pigmented aggregates, presenting as either coarse granules or pigmented clumps, accompanied this homogeneous pigmentation in 16 lesions. Matt black pigmentation, matt white pigmentation, yellow to brown pigmentation, black reverse triangle (wider at the distal than the proximal end), superficial transverse striation and blurred appearance were the other features.

Conclusions: We have identified a number of dermoscopic features appearing in fungal melanonychia, which should help in diagnosis of this disease.
