Maxillary sinusitis mimicking malignant disease.
The diagnostic features of both maxillary sinusitis and neoplastic disease of the antrum are described. In most cases the clinical and radiographic evidence will lead to the correct diagnosis. However, in the two cases presented here, the clinical and radiographic evidence of neoplastic disease of the maxillary sinus was not confirmed by biopsy and histologic examination. The significant fact that radiographic evidence of bone destruction of the antral walls can occur in maxillary sinusitis is discussed. This sign, together with a unilateral epistaxis, must always be considered as evidence of neoplastic disease of the maxillary sinus. Where there is any doubt, biopsy must be performed.
