Respiratory epithelial adenomatoid hamarthoma of the olfactory cleft: an endoscopic approach

Respiratory epithelial adenomatoid hamarthomas of the nose and paranasal sinuses (REAH) are relatively rare. These tumors usually do not extend over the boundaries of the nose and sinuses. The authors present a 65-year-old male suffering from progressive hyposmia, followed by intermittent stubborn headache. The symptoms lasted for almost two years and were getting worse very slowly. Fiberendoscopy showed relatively discrete polypoid tissue occupying olfactory cleft bilaterally. The computed tomography and magnetic resonance imaging suggested a possible lack of the cribriform plate and the unity and uniformity of the tissues located both in the endocranium and high in the nasal cavity. The clinical picture resembled very much esthesineuroblastoma. The patient underwent endoscopic sinus surgery under general hypotensive anesthesia. Frozen sections during surgery showed respiratory epithelial adenomatoid hamarthoma of the olfactory cleft (REAHOC). The entire tumor was removed in a piece-meal way. Since both olfactory bulbs were also involved they were removed too. This case showed that respiratory epithelial adenomatoid hamarthoma of the olfactory cleft (REAHOC) could be a locally aggressive process, penetrating even into the endocranium.
