Ultrasound biomicroscopy in pigmented conjunctival cystic nevi.
OBJECTIVE
To report the use of ultrasound biomicroscopy in the clinical diagnosis and management of pigmented conjunctival cystic nevi.


METHODS
Two patients, aged 11 and 18 years, with rapidly growing raised conjunctival melanocytic lesions suspected to be inflamed juvenile conjunctival nevus underwent ultrasound biomicroscopic and histopathologic examinations.


RESULTS
Ultrasound biomicroscopic examination of the lesions revealed multiple areas of cystic tissue, which is compatible with pathologic finding of compound nevus with epithelial inclusion cysts formation. Furthermore, clear interface was found between the mass and the underlying sclera.


CONCLUSIONS
Pigmented conjunctival nevi may obscure cysts under slit-lamp examination. Ultrasound biomicroscopy is a useful diagnostic adjunct to distinguish cysts in conjunctival lesions. Additionally, this technique may be helpful in delineating the extent of lesions prior to excision biopsy.
