A Case of an Uncommon Lower Lip Swelling.

A woman in her fifty-seventh year appeared with a painless swelling on her left lower lip that had been present for three years. The size of the swelling was noticeably increasing in size over time. On examination, there was a lump that was firm, non-tender, and measured 2 cm x 1 cm above the lower lip. The oral cavity, as well as the intraoral mucosa, were normal and unremarkable in appearance. As fine-needle aspiration cytology revealed a spindle cell lesion, she had an excision biopsy performed, followed by bilateral advancement flap closure. Histopathological examination (HPE) revealed a schwannoma in the tissue sample. Schwannomas are rare, benign neural tumors originating from Schwann cells. They are mainly asymptomatic and have a moderate rate of growth. Excision is the recommended treatment for schwannomas. Proper surgical planning and postoperative monitoring are crucial for optimal wound healing and complete recovery.
