Carcinoma of the esophagus with mixed basaloid squamous and glandular differentiation: A distinct histological presentation

Esophageal cancer is the third most common gastrointestinal cancer and ranks among the ten commonest cancers worldwide. Histologically, approx 60% of esophageal cancers are adenocarcinornas and 40% are squamous cell carcinomas (SCC). Other rare cancers of the esophagus include small-cell carcinomas, squamous cell carcinomas with sarcomatous features, adenoid cystic carcinomas, and mucoepidermoid carcinomas. Basaloid squamous cell carcinoma (BSCC) or basaloid squamous carcinoma (BSC) is a distinct clinicopathological entity, seen more frequently in elderly males. Stage at presentation is often advanced and regional adenopathy or distant metastases are not uncommon at presentation. We describe an unusual case report of esophageal BSCC with glandular differentiation. The clinical significance of glandular differentiation in this rare type of tumor is not known.
