Early Surgical Intervention in an Infant with Angiomyxoma: Ensuring Complete Excision and Prevention of Recurrence.

abstractAngiomyxoma is a rare, benign mesenchymal tumor rarely encountered in the infantile hard palate. This case report describes the presentation, diagnostic workup, and successful management of an angiomyxoma in an 11-month-old male infant. An 11-month-old male was presented to the ENT department with a slowly enlarging, asymptomatic palatal swelling first noticed at 9 months of age. Intraoral examination revealed a 2 cm × 2 cm, soft, nontender mass on the anterior hard palate. A contrast-enhanced computed tomography scan identified a well-defined, oval, heterogeneously enhancing cystic lesion (8 mm × 15 mm × 18 mm) with no bony erosion. The patient underwent complete surgical excision under general anesthesia. The lesion was excised in toto via an intraoral approach, revealing a well-encapsulated, gelatinous mass. Histopathological examination confirmed the diagnosis of angiomyxoma, showing spindle cells in a myxoid stroma with numerous thin-walled vessels. The postoperative course was uneventful, and the child resumed feeding normally. At the 6-month follow-up, there was no evidence of recurrence, and both functional and cosmetic outcomes were excellent. This case underscores that angiomyxoma, though rare, should be considered in the differential diagnosis of pediatric palatal masses. A combination of cross-sectional imaging and complete surgical excision is the cornerstone of management, leading to a favorable prognosis with low recurrence risk.
