title: False negative orbital fine needle biopsy.
abstract: Orbital fine needle aspiration biopsy is a useful diagnostic adjuvant. In this case, an FNAB showed lymphocytes. The surgeon felt that this diagnosis was possibly inaccurate, and therefore took out the tumor en bloc. This was a mucoepidermoid carcinoma involving the lacrimal gland that had been heavily infiltrated by lymphocytes.
