The patient was a febrile, and clinical oral examination revealed localised grade II mobility and absence of gingival swelling, erythema or sinus tract. Orthopantogram revealed a poorly defined radiolucency involving the upper left second and third molar teeth. Surgical exploration of the involved area was performed and revealed the presence of a \u2018jelly like\u2019 brown tissue that fragments easily.
