Harmartomas of the head and neck are common lesions, often taking the form of melanocytic nevi or vascular malformations such as hemangiomas and lymphangiomas. Hamartomas composed of other tissue types are much rarer and within the oral cavity are usually located on the tongue near the foramen cecum or on the anterior hard palate near the incisive papilla. Although most occur as isolated phenomena, a small number may be associated with other local developmental defects or with a syndrome complex. A normal 5-year-old girl had a 1 cm soft sessile swelling in the vault of the hard palate on the left side. Histopathologic examination showed bundles of smooth muscle embedded in fibrovascular stroma and accompanied by abundant mature fat and a small amount of salivary tissue. The features were regarded as those of a leiomyomatous hamartoma and could be distinguished from a smooth-muscle tumor, teratoma, and benign mesenchymoma by virtue of the clinical and histopathologic features. No recurrence has been seen after excision.
