A Case of Choroidal Metastasis from Small-Cell Lung Carcinoma

Abstract

A 74-year-old man visited to our hospital due to severe visual disturbance
in his left eye for recent one month. Fundoscopy demonstrated
the serous retinal detachment at the nose side of the left
eye.At the same time, chest X-ray demonstrated a mass measuring
4 cm in size at the left lower lung field (Figure 2, arrow)
and thoracic computed tomography (CT) depicted the mediastinal
lymphadenopathies. On Hematoxylin-Eosin stain, both specimens
obtained from right B10 by transbronchial lung biopsy (Figure 3A,
400X) and subcarinal lymphnodes (Figure 3B, 400X) by endobronchial
ultrasound-guided transbronchial needle aspiration demonstrated
abundant atypical cells with high nuclear cytoplasmic ratio.
Those cells were positive for both CD56 (Figure 3C, 400X) and
TTF-1 (Figure 3D, 400X), he was thus diagnosed with small cell
lung carcinoma (SCLC).
