However presentation of such patients with recurrent haemoptysis has not been described in the literature so far. We have described a case of an ectopic supernumerary molar tooth in the maxillary antrum in a patient who initially presented with haemoptysis. Case presentation A 45-year-old male presented with a 2-month history of episodic haemoptysis. A pedunculated growth from the inferior nasal turbinate was seen with fibre-optic visualization. Although the patient was empirically started on antibiotic and anti-allergic therapy there was no improvement after a few weeks and the patient had recurrent episodes of haemoptysis. Fibre-optic visualization was repeated showing bilateral osteomeatal erythema. Computed tomography scan of the paranasal sinuses demonstrated complete opacification of the left maxillary antrum along with a focal area of density comparable to bone. An ectopic supernumerary molar tooth was found in the left maxillary antrum on endoscopic examination and subsequently removed. In addition copious purulent discharge was seen. Post-operatively the patient was treated with a 10-day course of oral amoxicillin-clavulanate. On follow-up he reported resolution of symptoms. Conclusion Recurrent haemoptysis has not been described as a presentation for a supernumerary ectopic tooth in literature before. We recommend that in patients with sinusitis-type of opacification of maxillary antrum and whose condition is refractory to .
