Balloon nevus cells are an uncommon variation of the conventional nevus cell. These balloon cells have been reported to occur in nevi and in malignant melanomas of the skin and choroid. Balloon cells are considered to be nevus cells arrested in the stage of melanin synthesis. This report documents the occurrence of balloon nevus cells in an active, compound nevus of the palpebral conjunctiva.
