Abstract

Dentigerous cyst is normally associated with crown of an unerupted or developing tooth and is one of the most common odontogenic cyst. It is more commonly seen in association with mandibular third molar and maxillary canine. Dentigerous cyst generally occurs in second or third decades of life. Its association with incisors are rare entity. Dentigerous cyst usually includes a tooth which can not complete the eruption process and involves the crown by the fluid accumulation in between the layers of enamel organ. The treatment modalities for dentigerous cyst are marsupialization or enucleation and depends upon the involved structures. Here we report a case of dentigerous cyst associated with permanent mandibular lateral incisor. It was enucleated along with the lingually erupted lateral incisor. There was no recurrence observed after one year follow up. Keywords: Dentigerous cyst, Odontogenic cyst, Lateral incisor, Marsupialization, Enucleation.

Abstract

Chondrosarcoma is a malignant tumour of mesenchymal origin, after osteosarcoma. It is the second most common bone tumour. It is relatively a slow-growing tumour and is mostly detected in the base of the skull and the anterior maxilla. Here, we report a very distinct case of chondrosarcoma in maxillary sinus. A 65- year-old man reported with a tumour on the right maxillary sinus region. CT imaging showed an abnormal mass destructing surrounding tissues. Our case shows that radiography combined with histopathology is necessary to make the final diagnosis. The presented case revealed that chondrosarcoma can be a heterogeneous tumour. Keywords: Chondrosarcoma, Osteosarcoma, Mesenchymal tumour, Maxilla, Maxillary sinus.
