title: Cellular blue naevi with microalveolar pattern--a type of naevus frequently confused with melanoma.
abstract: We report on nine cases of cellular blue naevi with distinctive arrangement of cells into the microalveolar pattern. This microalveolar pattern was usually seen in the deeper parts of cellular blue naevi and was composed of a few epithelioid cells surrounded by bipolar dendritic pigmented cells. This unusual pattern often reminded of incipient malignant change within cellular blue naevi.
