In addition, the patient had a high arched palate and multiple impacted teeth of the normal series and supernumerary type including mesiodens as demonstrated in an orthopantomograph.展开更多

It is considered to be a solid variant of calcifying odontogenic cyst(COC). This tumor makes up for only 2%-14% of all COCs and less than 0.5% of all odontogenic tumors which owes to its rarity. The purpose of this paper was to describe a case of DGCT and the treatment adopted in our case,and to provide a review of this case in the indexed literature.CASE SUMMARY In this article, we discussed a case of 18 year old male who reported with a chief complaint of a recurrent swelling and dull aching pain in upper left back region of the jaw. Computed tomography scan was carried out which revealed hypodense lesion with a few hyperdense flecks within it suggesting the presence of calcification. On incisional biopsy, diagnosis of COC was given. After segmental resection of the lesion, histopathogically odontogenic epithelium was noted along with calcifications, ghost cells and dentinoid material. Special staining was done with van Gieson and it showed pink areas of dentinoid material and yellow colour represented ghost cells. Hence, amalgamation of careful clinical examination, use of advanced radiographic imaging and detailed histopathological examination confirmed the diagnosis of DGCT. The patient was followed up for one year and there was no recurrence of the lesion or signs of any residual tumor.CONCLUSION Radical treatment should be carried out along with mandatory long-term follow up in order to avoid recurrence in aggressive lesions.展开更多
