title: Adenosquamous carcinoma of oral cavity: a case report.
abstract: An elderly man presented with a pair of soft tissue swelling, one on upper and another on lower gums, with chest pain and respiratory distress. Histopathological examination of the biopsied material showed features suggestive of adenosquamous carcinoma, but CT-guided fine needle aspiration cytology from lung mass showed evidence of non-keratinising squamous cell carcinoma. This histologic dissimilarity between primary and metastatic tumour is a characteristic feature of the lesion. Palliative radiation was given as the patient was unfit for surgery, but his condition deteriorated rapidly and treatment had to be withdrawn.
