영문 초록

Pleomorphic adenoma (PA) is a commonly occurring benign tumor originating in the salivary glands. The incidence is mostly in the parotid glands (85%) followed by minor salivary glands (10%). Pleomorphic adenoma from minor salivary glands of the lips is a rare neoplasm. Here, we present a case of a patient with PA in the upper lip, reporting a common neoplasm in a rare site. A 82-year-old male with a slowly progressing swelling that occurred 20years ago on the upper white lip. This tumor is not associated with pain and tenderness. The mass was about 1.5x1.5cm sized, circumscribed, sessile and firm on the external upper lip without oral side bulging (Fig. 1). The tumor was removed completely with a elliptical incision under local anesthesia. The encapsulated mass was measured 0.9x0.9x0.6cm. On histology, a well-circumscribed growth was seen comprising epithelial and stromal components. The epithelial component formed glandular structures lined by round-to oval cells having small nuclei, pink cytoplasm and myoepithelial basal cell layer while the stroma had a fibromyxoid appearance(Fig. 2). Postoperatively wound was well healed without recurrence after 6months. Pleomorphic adenoma of the upper lip is a rare neoplasm, especially not intraoral growth. For aesthetic good result, the mass was removed without hesitation. It is required a high index of suspicion and a long-term follow-up because it could recur and rarely be transformed into malignancy.
