title: Choroid metastases revealing primary clear cell adenocarcinoma of the lung effectively treated with cisplatin and pemetrexed: a case report.
abstract: BACKGROUND
  The aim of the present report was to draw the attention of oncologists to the importance of prompt diagnosis of primary clear cell adenocarcinoma of the lung, which allows early initiation of treatment to maintain quality of life.
  
  
  METHODS
  A 63-year-old Chinese woman initially presented to our facility with multifocal bilateral choroid metastatic lesions that were found to originate from a primary clear cell adenocarcinoma of the lung (T2bN2M1b, stage IV). A thorough ophthalmologic evaluation, study of our patient's history, imaging studies and comprehensive immunohistochemical staining tests led to the diagnosis of this rare lung tumor.
  
  
  CONCLUSIONS
  Although this uncommon cancer is unfortunately already at a late stage when choroid metastases develop, systemic chemotherapy alone is sufficient to preserve vision and gain control over the disease.
