CHARACTERISTICS OF THE DERMOID CYST: A CASE REPORT

A 42-year-old male, feoderma, reported that a year and a half ago an asymptomatic nodule appeared on his face and the size had increased in the last 5 months. In his medical history, he reported being hypertensive and diabetic, both controlled. In extra-oral physical examination, a nodular, rounded mass was observed in the region of the left zygomatic bone, resilient to palpation, 4 cm in diameter. In the excisional biopsy a total removal of the lesion was performed. During surgery, a whitish pasty content was appreciable. Microscopic sections revealed a virtual cystic cavity covered by orthokeratinized, stratified pavement epithelium with well-marked granular layer, filled with keratin blades. Underlying delicate fibrous capsule was noted. The diagnosis based on the clinical and microscopic characteristics was a dermoid cyst. Fifteen days after surgery the stitches were removed. After 1 month, there was no recurrence of the lesion, he had excellent healing, and he was discharged.
