PURPOSE: To evaluate the clinical relevance of subcentimetric lymph node biopsy via mediastinoscopy in patients with presumed ocular sarcoidosis (OS).
METHODS: Retrospective study of consecutive patients who underwent biopsy via mediastinoscopy for suspected OS. The biopsy outcomes and clinical features of patients with subcentimetric nodes and of those with lymph nodes >1 cm were compared.
RESULTS: A total of 67 patients with presumed OS were included. Forty-two patients (63%) had lymph nodes ≥1 cm in diameter, while 25(37%) showed subcentimetric lymph nodes. Biopsy was consistent with sarcoidosis in 83% of patients with lymph nodes ≥1 cm and in 76% of patients with subcentimetric lymph nodes (p = .60). Patients with OS who had subcentimetric lymph nodes had less lymphopenia (p = .01), lower lysozyme values (p = .03) and a longer diagnostic delay compared to those with larger lymph nodes.
CONCLUSIONS: The biopsy of subcentimetric lymph nodes via mediastinoscopy may provide a histological diagnosis and reduce diagnostic delay.
