Hamartoma is a tumor-like malformation in which the tissues are arranged haphazardly with an excess of one or more of its components, although the underlying reasons for the occurrence of hamartoma is not fully understood. Hamartoma commonly originates from the lung, kidney and intestine. However, hamartoma is very rare in the head and neck, especially in the palatine tonsil. Presenting symptoms of hamartoma are typically vague and nonspecific. Complete surgical removal of the hamartoma is the treatment of choice as incomplete treatment leaves the risk of recurrence. Recently, we have experienced a 22 year-old male patient who presented with a mass at the posterior pillar area of the right palatine tonsil of several years. The mass was resected completely and confirmed histologically as a hamartoma. Therefore, we report this case with a brief literature review.
