In this study of 22 patients with laryngeal cancer, computed tomographic (CT) scans in the axial plane were compared with histopathological sections prepared in the same plane. The value of the preoperative CT for evaluating tumor invasion, location and size was then investigated. Findings demonstrated that CT was most sensitive in determining tumor invasion to the paralaryngeal and preepiglottic spaces, anterior and posterior commissures and subglottis. In contrast, CT was less sensitive in determining actual tumor invasion to the laryngeal cartilages, extralaryngeal tissues and metastases to cervical lymph nodes.

A solitary fibrous tumour is a pleural tumour which may rarely be detected at non-pleural sites. In this report, the case of a solitary fibrous tumour arising from the sublingual salivary gland is described.

A rare undifferentiated carcinoma with lymphoid stroma (UCLS) of the parotid gland is described in a white Turkish patient. The raised serum IgG to Epstein-Barr virus capsid antigen suggests a causal relationship between Epstein-Barr virus and this type of salivary gland carcinoma. Some clinical features are briefly reviewed.
