Abstract

Fibrolipomas are a rare microscopic variant of lipomas, characterized by mature adipose tissue interspersed with dense fibrous connective tissue. These lesions are rarely observed in the head and neck region and represent <0.6% of all benign tumors of the larynx and hypopharynx. Their clinical presentation depends on the location and size of lesions. Patients present with variable symptoms; however, fibrolipomas of the larynx and hypopharynx are clinically important because these tumors can cause unpredictable airway obstruction, particularly during general anesthesia induction. We present a case of a hypopharyngeal fibrolipoma in a 61-year-old patient with frequent dyspnea, dysphagia, and muffled voice. Laryngoscopy revealed a well-demarcated pedunculated ovoid mass involving the larynx. We performed laryngomicrosurgery using a carbon dioxide laser for surgical excision and subsequent evaluation confirmed the diagnosis of fibrolipoma. We report a case of hypopharyngeal fibrolipoma, together with a literature review.
