An 8-month-old boy presented with a lesion on the plantar aspect of his left hindfoot. The lesion was completely asymptomatic and, according to the child's parents, had been present since birth but grew proportionally to the infant. Physical examination revealed a soft, non-tender, subcutaneous nodule approximately 1 cm in diameter anterior to the heel with normal overlying skin (Figure 1). A full skin examination showed no other abnormalities elsewhere. The patient had an ultrasound scan of the lesion followed by a diagnostic punch biopsy. Ultrasound examination showed a relatively ill-defined thickening of the skin and underlying subcutaneous tissue corresponding to the visible and palpable nodule, measuring 8 mm in diameter and 3 mm in thickness. There was no evidence of vascularity with Doppler ultrasound and no underlying fluid collection or discrete mass. The underlying musculo-tendinous structures were unremarkable (Figure 2). Histopathology of a punch biopsy is shown in Figure 3.
