Adenosquamous carcinoma of paranasal sinuses and Kartagener syndrome: an unusual combination
A 34 years old non-smoker male patient reported with growth of right maxillary region which on histopathology confirmed adenosquamous carcinoma of nose and paranasal sinus. Patient also had total situs inversus including dextrocardia, bronchiectasis and sinusitis. His blood group was AB negative. This association of Kartagener syndrome with adenosquamous carcinoma of paranasal sinuses has never been reported. Carcinoma of paranasal sinuses accounts only 0.3% of all cancers. Adenosquamous carcinoma makes only 2% of the nose and paranasal sinuses tumours. Kartagener syndrome, AB negative blood group and adenosquamous carcinoma of paranasal sinuses all are extremely rare clinical conditions found in populations and the combination of all three in the same patient have never been reported to the best of authors' knowledge.
