ABSTRACT

Objective: To determine the main clinical and histopathologic features of the epibulbar choristomas in a Mexican population.
Material and methods: Retrospective review of cases with clinical and histopathologic diagnosis of epibulbar choristomas (dermolipoma, limbic dermoid, complex choristoma and epibulbar osseous choristoma) from January 1957 to August 2002.
Results: Of 188 patients with diagnosis of epibulbar choristomas histopathologically confirmed, only 145 were included in the current study.100 dermolipomas were found, 29 dermoid, 3 complex choristomas and 13 epibulbar osseous choristoma. Most of them were composed of adipose tissue and dense connective tissue; linned by a keratinized squamous epithelium and sometimes without keratin. Some presented hair follicles, sweat glands, sebaceous glands, lachrymal gland, bone or cartilage attached.
Conclusions: Epibulbar choristomas are benign congenital tumors, of slow growth, most of the times asymptomatic. Dermolipoma and dermoid are the most frequent types. Treatment my be a periodic evaluation or the surgical excision of the tumor, in order to improve the cosmetic appearance or to avoid conjunctival irritation.
