A Case of Metastatic Iris Tumor from Adenocarcinoma of the Cecum Diagnosed by Combined Tumor Markers in Aqueous Humor and Fine Needle Aspiration Cytology.

ABSTRACT:

Introduction

The diagnosis of metastatic iris tumor is made by a fine-needle aspiration biopsy of part of the solid component of the tumor and tumor cells seeded in the anterior chamber; however, sometimes the diagnosis is not made due to insufficient sample volumes. We report a case of metastatic iris tumor in which measurement of tumor marker levels in the aqueous humor together with fine needle aspiration cytology contributed to the diagnosis.

Case report

An 80-year-old Japanese woman was referred to our hospital because of an iris mass. Six months before the initial visit, the patient was diagnosed with adenocarcinoma of the cecum. Slit-lamp microscopy revealed an elevated iris mass. Fine-needle aspiration cytology suggested adenocarcinoma. The carcinoembryonic antigen (
