Radiographically, the multilocular lesion involved the left lower first molar and was 30 mm long by 20 mm high. Dental extraction of the molar involved with forceps and exeresis in toto of the tumor were performed using a Volkmann cutting curette. The tumor made up of 90% vascular tissue produced intra-surgical bleeding that made visibility difficult. The bone bed curettage was aggressive except for its base in direct contact with the inferior dental nerve. Subsequently, to avoid recurrence, the surgical protocol includes a double irrigation with Carnoy’s solution, (fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid 98%) for 5 minutes that produces chemical cauterization. Finally, it was washed with physiological solution and the cavity was filled with iodoformed gauze. The gauze was exchanged and removed gradually over three weeks for second intention healing. This case is presented to demonstrate that inexpensive chemical treatment can be safely used for outpatient surgery under local anesthesia. Because Carnoy’s solution achieved control of intraoperative bleeding, allowed bone healing and prevented recurrence of the lesion in clinical radiographic follow-up for 15 years.展开更多

Occasionally, central giant cell granuloma-like lesions may be seen in association with hyperparathyroidism. Rarely, PGCG-like lesions have been described in a background of hyperparathyroidism. We describe the case of a 91-year-old woman taking teriparatide for the treatment of osteoporosis and presented with a peripheral giant cell granuloma of the mandibular posterior area.展开更多

Its etiopathogenesis is unclear; however it is suggested that it can arise as a reactive response to trauma. This report describes an aggressive variety of CGCG which raises a question; can extraction of tooth modify the behavior of CGCG? A 46 years old male had reported with a rapidly increasing intraoral and extraoral swelling of lower jaw following tooth extraction. Radiographic examination revealed a large multilocular lesion involving the body and ramus of mandible which had been proved to be aggressive CGCG on histopathological examination. The importance of radiographic examination prior to extraction of teeth and importance of inclusion of CGCG in jaw swellings associated with mobility of teeth or failure of healing sockets is emphasized.展开更多

It is rare in the nasal cavity and paranasal sinuses. Here we report a case of GCRG of nasal cavity in 24-year-old man who came with unilateral nasal obstruction, epistaxis and proptosis. CT scan showed soft tissue hypodensity lesion of left nasal cavity. Endoscopic surgical excision and biopsy were done. The pathology was consistent with GCRG. There was no recurrence seen on follow-up for 2 years. A short literature review about diagnosis, clinical behavior, radiological findings and treatment of this tumor entity are given.展开更多
