RESUMO
INTRODUCTION: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic. CASE REPORT: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT) scan. We resected the cystic mass using the Caldwell-Luc procedure. A definitive diagnosis was confirmed by postoperative histopathologic examination. CONCLUSION: Hydatid cyst of the maxillary sinus is an extremely rare presentation. However, this condition should be considered in differential diagnosis of cystic lesions of the maxillary sinus.
RESUMO
Supernumerary nostril is an extremely rare congenital entity which results from aberrant embryological development. The review of the literature reveals that only 30 cases of supernumerary nostril have been reported. We report a rare case of supernumerary nostril in association with esophageal atresia, imperforate anus, and patent ductus arteriosus. To our knowledge, this is the first case of supernumerary nostril which has been accompanied by three other congenital anomalies. In addition to the presented case, we review all the literature cases of supernumerary nostril.
