Malignant tumours of the nasal cavities and paranasal sinuses are uncommon. They constitute less than one per cent of all tumours and less than three per cent of head and neck tumours. Although multiple primary carcinomas of the aerodigestive tract are commonly reported, metachronous maxillary sinus carcinomas are rare. To date, all of these cases reported are of squamous cell origin. The incidence of metachronous maxillary carcinoma involving both sinuses is in the range of 1.4 per cent amongst patients with maxillary carcinoma. We present the first reported case, to our knowledge, of a patient with metachronous adenocarcinoma of the maxillary sinus.
鼻腔和鼻窦的恶性肿瘤并不常见。它们占所有肿瘤的比例不到1%，占头颈部肿瘤的比例不到3%。虽然上消化道多原发性癌常见报道，但异时性上颌窦癌却很罕见。迄今为止，所有报道的这些病例均为鳞状细胞起源。在上颌窦癌患者中，累及双侧鼻窦的异时性上颌窦癌发病率在1.4%左右。据我们所知，我们报告了首例异时性上颌窦腺癌患者。
