title: Basaloid-squamous carcinoma. A distinct histopathological entity.
abstract: Basaloid Squamous Carcinoma (BSC) is an uncommon aggressive neoplasm occurring in the upper aerodigestive tract. Lung as a primary site has only recently been reported. A combination of microscopic features is required to make a diagnosis and to differentiate it from other more common malignancies in these sites. Three cases of BSC including one in the lung are reported. There are no prior published reports of this neoplasms in Indian literature. The study highlights the typical microscopic features and the diagnostic difficulties which may be encountered.
