Botryoid odontogenic cyst is an unusual and rare type of odontogenic cyst.
(a) Low risk group: included patients with embryonal RMS or botryoid who had
Polycystic lesions are called botryoid odontogenic cysts, due to their resemblance to a cluster of grapes.
The embryonal RMS is divided into two different subhistological-types: Spindle Cell RMS and Botryoid RMS.
The International Classification of Rhabdomyosarcoma (ICR) provided a prognostically relevant classification system that has been in use since 1995.1 This system included histologic subtypes with a superior prognosis (botryoid and spindle cell rhabdomyosarcoma [RMS]), an intermediate prognosis (typical embryonal RMS) and a poor prognosis (alveolar RMS).
Better clinical outcome is associated with botryoid and spindle cell variants of embryonal RMS.
Characteristic botryoid inclusions were detected in more vaccinated than control pigeons, but this difference was not significant.
A rare variant of lateral periodontal cyst, the botryoid cysts represent a polycystic variant of LPC, first described in 1973 by Weathers and Waldron.
The tumor shows a botryoid growth pattern into the lumen of the bile duct.
In 1995, the Intergroup Rhabdomyosarcoma Study proposed the "International Classification of Rhabdomyosarcoma," in which 4 main subtypes of RMS were established: 1) botryoid and spindle cell variants of embryonal rhabdomyosarcoma (ERMS) with a favorable prognosis; 2) conventional ERMS with an intermediate prognosis; 3) alveolar rhabdomyosarcoma (ARMS) with a poor prognosis; and 4) undifferentiated sarcomas, also with a poor prognosis5.
