Ocular sarcoidosis presenting as a solitary choroidal mass

Ocular sarcoidosis presenting as a solitary choroidal mass without other signs of intraocular inflammation is a rare manifestation of systemic sarcoidosis. The authors describe a 26-year-old man who presented with a solitary choroidal tumour. Ocular and general physical examination as well as serum chemistry studies and pathological examination of a lymph node biopsy specimen confirmed sarcoidosis as the cause of the mass. Treatment with systemic steroids resulted in improvement in the appearance of the lesion; however, the visual acuity remained impaired. Other such cases reported in the literature are reviewed.
