A 6-year-old girl with no significant past medical history presented with an asymptomatic, solitary lesion on her left wrist. On examination, there was an approximately 1.0 x 1.5 cm-sized, well-circumscribed, ovoid, brownish plaque, with a centrally located hyperkeratotic and slightly scaly papule (Fig. 1). Biopsy findings revealed slightly increased numbers of eccrine glands without any other abnormalities, consistent with an eccrine nevus (Fig. 2).

Although there were no symptoms, the lesion was removed by surgical excision, and there has been no recurrence in the year after treatment.
