Inverted papilloma of the lacrimal sac, the paranasal sinuses and the cervical region.
A 22-year-old woman presented with a lacrimal sac mass which on biopsy was an inverted papilloma. Two years later an ipsilateral cervical mass was removed, which contained inverted papilloma with a histologically typical pattern. Subsequently, the patient had a medial maxillectomy and remains well 5 years later. The cervical mass may represent inverted papilloma arising in a branchial cleft cyst or it may be a metastasis of benign papilloma to a regional lymph node. This is the second such case reported and the first with substantial followup.
