title: Botryoid odontogenic cyst: a diagnostic chaos.
abstract: Botryoid Odontogenic cyst (BOC) originally described by Weathers and Waldron (1973) is a variant of a lateral periodontal cyst characterized by macroscopic and microscopic multilocular growth pattern. We report a case of BOC in a 21-year-old male patient. Orthopantamogram revealed a multilocular radiolucency extending from 43 to 47. The histological examination of incisional biopsy revealed a thin 2-4 layered non keratinised epithelium without rete ridges resembling a reduced enamel epithelium with few localised plaque like thickenings and occasional mural bulges. These features were suggestive of BOC. The excisional biopsy revealed histological features similar to those of incisional biopsy except for the presence of 5-6 epithelial follicles with outer columnar cells and inner stellate reticulum like cells. CD56 and calretinin immunohistochemical staining (IHC) was done. This paper highlights the unusual appearance of follicles in BOC with differential diagnosis and IHC staining characteristics.
