RESUMEN
Pleomorphic adenoma is a benign tumor that can occur in the salivary glands, most commonly in the parotid gland. While it primarily occurs in the major salivary glands, it can sometimes be found in the minor salivary glands. Within the minor salivary glands, it most often originates in the hard palate and soft palate, and less frequently in the upper lips. Due to its location in the minor salivary glands, most pleomorphic adenoma involve and protrude on the mucosa. A 61-year-old man presented with 1.5 cm exophytic mass on the skin of his upper lip. This mass was exophytic on the skin and did not involve or protrude into the inner lip mucosa. The mass was entirely excised, and a subsequent permanent biopsy diagnosed it as a pleomorphic adenoma. In such situations, it can be challenging to suspect pleomorphic adenoma during a physical examination, leading to potential diagnostic confusion. It might also be mistaken for an inclusion cyst or another type of mass, making it tempting to treat without verifying the pathological results.
RESUMEN
The mouth is a unique and prominent element of the lower face. Given the complex anatomy, aesthetic appearance, and function of the oral commissure, its reconstruction due to various causes presents a significant challenge for surgeons. Squamous cell carcinoma (SCC) of the lip is the most common type of oral cancer, accounting for approximately 25% to 30% of all oral cancers. Wide excision is the treatment of choice, and the prognosis is generally favorable. We encountered a case of SCC of the right oral commissure in a 69-year-old man. We designed a hatchet-shaped flap to minimize anatomical disruption and, as a result, achieved satisfactory outcomes in terms of both functionality and aesthetics.
