Squamous cell carcinoma of the oesophagus with mucin-secreting component (muco-epidermoid carcinoma and adenosquamous carcinoma): a clinicopathologic study and a review of literature.
The clinicopathological features of 11 cases of primary oesophageal squamous cell carcinomas with mucin-secreting component (eight muco-epidermoid and three adenosquamous carcinomas) are presented. The incidence was 2.2% of all resected primary oesophageal tumors. The mean age was 64 years and the male to female ratio was 4.5:1. The mean diameter of these tumours was 4 cm. Twenty-seven per cent of these tumours were in the upper, 46% in the middle and 27% in the lower portion of the oesophagus. The age, sex and site distribution of these tumors were similar to those of squamous cell carcinomas. The medium survival of these patients was 15 months. The world literature concerning this rare entity was reviewed and compared with the findings of the present study. No major racial differences were noted. In addition, the classification of this group of tumours was also discussed.
