Botryoid odontogenic cyst. Report of a case with histologic evidence of multicentric origin.

Histologic examination of an excisionally biopsied botryoid odontogenic cyst (BOC) documented that it was composed of at least 2 separate cysts, the location of which suggested that both originated within the alveolar bone rather than from within the periodontal ligament. These observations provide evidence for a multicentric origin of this example of BOC, and are consistent with a previous suggestion that lateral periodontal cysts of non-inflammatory origin arise from remnants of the dental lamina.
