An expansive papilloma of the nasolachrymal drainage system harbouring human papilloma virus.

We report a case of an expansive tumour extending from the lachrymal sac into the adjacent maxillary sinus. Histology showed a benign exophytic papilloma. By means of the in situ (DNA) hybridization technique, human papilloma virus (HPV) 6/11 were demonstrated, indicating a viral aetiology, similar to exophytic papillomas of the nose and larynx.
