Abstract

Malignant sinonasal carcinomas are a rare entity comprising less than 1% of all cancers and around 3% of all head and neck malignancies seen in humans. Among this 15-20% are transitional cell carcinoma also known as non-keratinizing carcinomas of sinonasal tract or cylindrical cell carcinoma or Schneiderian carcinoma or Ringertz carcinoma or respiratory epithelial carcinoma. We are reporting a case of 72 years old gentleman presented with CVA and during brain CT a right nasal mass lesion found incidentally. Endoscopy assisted biopsy was taken which revealed sinunasal carcinoma of transitional type. Very few reported cases were found upon searching the English literature. A possible reason could be histopathological challenges or the multiple synonyms of this tumor.

Keywords Transitional Cell Carcinoma; Nonkeratinizing Carcinoma; Schneiderian Carcinoma; Cylindrical Cell Carcinoma; Ringertz Carcinoma; Respiratory Epithelial Carcinoma
