Abstract

Hamartomas are non-neoplastic malformations or congenital errors of tissue development. Hamartoma is composed by an excessive growth of mature tissue present in wrong proportions and abnormal arrangements. The lesion usually presents as a submucosal mass with ill-defined margins. Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, hamartoma is very rare in the head and neck. Presenting symptoms of hamartoma are typically vague and nonspecific. Treatment of hamartomas consists of adequate surgical excision. We present a 59 year-old male patient who presented with submental swelling. Malignancy could not be ruled out with preoperative radiologic examination, so surgical excision was planned. The mass was excised with transcervical approach. Histopathologic examination has confirmed the mass as a mucinous gland adenomatoid hamartoma.
