Cystic benign melanosis of the conjunctiva.

PURPOSE: To report the clinical and histologic features of cystic benign melanosis.

METHODS

This case series reports on the clinical and histopathologic features of 3 patients with enlarging, cystic, brown, pigmented, conjunctival lesions.

RESULTS

Slit-lamp examination showed cystic melanotic lesions of bulbar conjunctiva. Histopathologic examination of the biopsy specimens showed epithelial lined cysts in the substantia propria, goblet cells, and secondary pigmentation of basilar keratinocytes.

CONCLUSIONS

Cystic benign melanosis, a unique conjunctival lesion, should be differentiated from cystic nevus and primary acquired melanosis.
