A 1-month-old boy was referred to the Pediatric Dermatology Unit with a solitary asymptomatic nodule on the back. The patient was born at 38 weeks gestation after an uncomplicated delivery. The congenital lesion appeared first as a rounded ulceration and started to become exophytic after the second week of life. At the first visit, it presented as a pink well-defined nodule, firm in consistency, with a partially eroded and crusted surface, measuring about 2 · 1.5 cm (Fig. 1). Full blood count, serum chemistry, liver function tests, and a complete physical examination were unremarkable. Case 2An unrelated 3-month-old boy, born by natural delivery after an uneventful pregnancy and in good general condition, was evaluated for a congenital asymptomatic nodule on the medial side of the right thigh. It presented as a solitary dull red nodular lesion of 1 cm in diameter, with an infiltrated erythematous border, and a small central irregular ulceration covered with a yellowish crust (Fig. 2). Full blood count, serum chemistry, liver function tests, and complete physical examination were normal. A 4-mm punch biopsy was performed in each case and the histopathology showed similar findings (Fig. 3).
