Basaloid Squamous Cell Carcinoma, Esophageal
Synonyms
There are no current synonyms for this neoplasm. Historically, it has been confused with another neoplastic entity, namely adenoid cystic carcinoma.
Definition
A malignant epithelial neoplasm composed of closely packed cells with hyperchromatic nuclei and scant cytoplasm, with a solid growth pattern, small cystic spaces, and foci of necrosis. The diagnosis depends on the demonstration of squamous cell dysplasia/carcinoma in situ in the overlying mucosa.
Clinical Features
Incidence
Basaloid squamous cell carcinoma (BSCC) is a rare entity and there are no global worldwide incidence data available. In most published series, the incidence ranges from 0.07% to 11.3% of all esophageal carcinomas.
Age
In the published series, the mean age at the time of diagnosis is around 60 years.
Sex
There is a slight predominance in males.
Site
This type of neoplasm has been classically described in the upper aerodigestive tract, namely at the larynx and the esophagus, but it can also be...
