Fungus infection of the maxillary sinus has been considered a rare disorder; recently, however, such cases have been reported in increasing number. The authors have recently observed five cases of mycosis of the paranasal sinuses. Three of these cases showed the clinical symptoms and signs of swelling and pain in the cheek area and epistaxis and aroused suspicion of maxillary cancer. Of the remaining two cases one was misdiagnosed as maxillary cancer with pulmonary metastasis and radiation therapy without preliminary tissue diagnosis given because of the poor general condition of the patient. On improvement of the patient's condition exploratory maxillotomy and mucosal biopsy revealed mycotic invasion; in the other, chronic bacterial maxillary sinusitis was suspected, but exploratory sin‐usostomy showed mycosis. The authors emphasize an apparent increasing frequency of mycosis of the paranasal sinuses and the fact that the symptoms and signs of mycotic invasion may duplicate those of early malignancy of this area.
