Research progress of ocular choristoma / 中国医师杂志

ABSTRACT

Ocular choristoma is composed of ectopic tissues with normal structures. The pathogenesis still remains uncertain. Histopathologically, it is a dense connective tissue mixed with epidermal appendages, smooth muscle cells, mature adipose tissue, lacrimal glands, lymph nodes, skeletal muscle fibers, cartilage and bone. Because of its low incidence, most of published literature are case reports. The clinical manifestations are non-specific and we need to distinguish it from other ocular masses. The choice of surgical resection depends on the ocular symptoms, the effect on appearance, and the need for clinical confirmation. This paper reviews the epidemiology, etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis and treatment of ocular choristoma.
