Resumo: Oral rhabdomyomas are rare benign neoplasms that primarily affect male adults over the age of 50. A 53-year-old male presented with a two-year asymptomatic mouth floor swelling, recently causing food ingestion and speech difficulties. Intraoral examination revealed a fibrous swelling, slightly larger on the left, smooth with no color change or tenderness. No triggering factors were reported, and the patient had no history of smoking, alcohol use, or systemic health issues. Dermoid or epidermoid cysts were ruled out via aspiration puncture. An incisional biopsy was performed with a differential diagnosis of salivary gland neoplasm versus leiomyoma. The microscopical study confirmed rhabdomyoma diagnosis, showing polygonal neoplastic cells with vacuolated and granular cytoplasm. The neoplastic cells tested positive for PAS and showed strong positivity for HHF35 and desmin, while they were negative for S100 and smooth muscle actin. Surgical removal was performed, and the patient is living well with no recurrence.
