INTRODUCTION: Although pleomorphic adenoma (PA) is the most common neoplasm of both minor and major salivary glands, its presence in the buccal surface of upper lip is rare.
PRESENTATION OF CASE: A 70-year-old male presented with a chief complaint of recent rapid growth of a mass in the buccal aspect of the upper lip. A well-circumscribed mass measuring 3 × 2 cm with intact overlying mucosa without regional lymphadenopathy was evident. Core needle biopsy report was suggestive of PA. Complete excision of the tumor was performed. The defect was large and primary closure was not possible. Reconstruction with FAMM flap was planned. After 4 weeks, the flap was covered with epithelia and created a satisfactory result.
DISCUSSION: The definite diagnosis of PA is based on histopathological examination. The following features help to differentiate PA from other tumors; tubuloalveolar and gland-like structures, islands of cuboidal or polygonal cells in a chondroid, hyalinized, fibroadipose or mucinous hypocellular stroma which are stained positively for periodic acid-Schiff and Alcian. Despite these characteristics, differentiation of PA from dermal mixed tumor may be challenging especially when the specimen is from the upper lip. The main advantages of FAMM.F are being thin and pliable flap, having wide arc of rotation; being suitable for reconstruction of mucosal defects; resistance against postoperative radiotherapy and easy harvesting.
CONCLUSION: The FAMM flap is a reliable reconstruction technique for medium-sized intraoral defects with limited morbidity to the donor site. It provides functional reconstruction of the oral cavity with a low risk of post-operative complications.
