A 2-day-old girl was referred because of a large ulcer on her right forearm that was present at birth. Pregnancy and delivery had been uneventful, and there was no relevant familial history. Weight and length were normal for gestation and her Apgar at birth was 8/9.On examination, an 8 x 4 cm ulcer was seen on the right forearm, with irregular, erythematous borders, covered by a thin, transparent membrane (Figures 1 and 2). The patient was afebrile and appeared in good general health, but right limb motility was reduced. Peripheral pulses were present. Hemogram and serum chemistry were normal, and TORCHS serologies were negative. The patient was admitted and treated with systemic clindamycin and topical wound care including mupirocin ointment. The ulcer successfully healed in six months with scarring. Limb mobility was largely restored, although some forearm contracture still remained on discharge.
