Clinical Misdiagnosis of Steatocystoma Simplex of Eyebrow in a Pediatric Patient

377 To the Editor: A 4‐year‐old girl presented with a 16‐month history of swelling of the eyebrow. Pediatricians and general surgeons diagnosed her with sebaceous cyst, and because of unsuccessful treatment with two surgical drainages and antibiotic therapy, she was referred to our unit. On examination, a soft, freely movable, nontender subcutaneous lesion was noted on the left eyebrow [Figure 1]. Other findings of the examination were unremarkable, and there was no family history of similar lesions. Upon our presumptive diagnosis of dermoid cyst, we excised it, and the intraoperative view revealed a soft mobile cystic lesion with a fibrous‐like wall filled with oily yellow fluid without surrounding soft‐tissue invasion. Findings of histopathological examination were compatible with steatocystoma [Figure 1], so she was diagnosed with steatocystoma simplex. At the 5‐year follow‐up, there were no signs of recurrence or development of other cutaneous cystic lesions.
