A 6-year-old male child presented to us with a single, asymptomatic, verrucous lesion over right elbow since 6 months. The lesion was initially small and slowly progressed with time to attain the present dimensions. Apart from a history of occasional bleeding after minor trauma, there were no other complaints. Physical examination revealed a solitary, slightly scaly, erythematous, verrucous nodule of about 1 × 1 × 1 cm in size over right elbow. The nodule was firm in consistency on palpation and did not elicit any tenderness [Figure 1]. The child was in good general health. A biopsy was taken from the lesion.

What is your diagnosis?
Histology showed moderate epidermal hyperplasia with focal hypergranulosis [Figure 2]a, [Figure 2]b, [Figure 2]c, [Figure 2]d. Several vertically oriented small and medium sized nests of epithelioid melanocytes were seen at dermo-epidermal junction. The entire dermis was infiltrated by nests and small cords of spindled and epithelioid melanocytes with a sparse to moderately dense lymphocytic infiltrate. Immunohistochemistry showed positivity for S100 and Melan A [Figure 3]a and [Figure 3]b.
