Angioleiomyoma or vascular leiomyoma is a rare benign tumor formed by smooth muscle cells in the
vascular wall or by remnants of embryonic tissue, commonly found in the uterus (95%), skin (3%), and
gastrointestinal tract (1.5%).
Less than 1% of all vascular leiomyomas occur in the nasal cavity. The origin of angioleiomyoma of the nasal cavity is uncertain,
partly due to the scarcity of smooth muscle in the nasal cavity. Three hypotheses have been proposed for the origin of smooth
muscle tumors in the nasal cavity: from aberrant undifferentiated mesenchymal cells; from elements of smooth muscle in the
walls of blood vessels and of piloerector muscles; or from both previous hypotheses, simultaneously. Some articles indicate that
sexual hormones and Epstein-Barr virus infection can affect the genesis of nasal angioleiomyoma.
The literature shows a prevalence of angioleiomyomas of the nasal cavity in female patients (in a 2:1 ratio between females and
males) between the fourth and sixth decades of life, and affecting mainly the inferior nasal conchae. These angioleiomyomas
develop in the mucosa of the nasal cavity as single solid small cutaneous masses. They can be painful or not and can expand.
They usually manifest as epistaxis (56.25%) and with nasal obstruction (56.25%).
In this report, we present the case of a 43-year-old man with a diagnosis of angioleiomyoma of the nasal cavity.
