*Dr. Himanta Bansal **Dr. George Koshy ***Dr. Alka D. Kale ***Dr. Rashi Behl The Journal An unusual case of Dentinogenic ghost cell tumor with Adenomatoid odontogenic tumor features Dentinogenic ghost cell tumor is an extremely rare odontogenic tumor and accounts for only 2% to 16% of all Calcifying Odontogenic Cysts. Dentinogenic ghost cell tumor was first described by praetorius et al in 1981 as a neoplastic variant of Calcifying Odontogenic Cyst. We report an unusual case of Dentinogenic ghost cell tumor that occurred in left posterior mandible of a 25 year old man. The tumor showed nests or clusters of proliferative odontogenic epithelium with ghost cells and massive juxtaepithelial tubular dentinoid material, diagnosed as Dentinogenic ghost cell tumor. The interesting and prominent feature was presence of Glandular/ ductal pattern of epithelium with eosinophilic coagulum, amyloid and dystrophic calcification, features resembling Adenomatoidodontogenic tumor. After the surgical removal, the patient was recalled for periodic follow up and has remained symptom free for the last 8 years.

After the surgical removal, the patient was recalled for periodic follow up and has remained symptom free for the last 8 years. Case Study A 25 year old man reported to the department, with complaints of pain and swelling in the lower left posterior region of mouth since 1 month. The patient gave history of trauma in the same region 5 years back and a small swelling which had been gradually increasing in size. On extraoral examination a diffuse swelling measuring approximately 4x3 cms in size was observed in the left body of the mandible. The overlying skin was stretched but normal in colour. There was no local rise in the temperature. Fig 1 Intraorally, the swelling was seen in the left mandibular premolar-molar region resulting in the obliteration of the vestibule. The mucosa over the swelling was intact and normal in color. *Professor & HOD, Department of oral and maxillofacial Pathology, BJS Dental College, Hospital & Research Institute Ludhiana, Punjab, India **Professor & HOD, Department of Oral and Maxillofacial Pathology, Christian Dental College, Ludhiana, Punjab, India. ***Principal and Professor, Department of Oral and Maxillofacial Pathology, K.L.E.S Dental College, Belgaum, Karnataka, India. ****Professor, Department of Oral Surgery, BJS Dental College, Hospital & Research Institute Ludhiana, Punjab, India. 29 22 10 3 1 21 23 Vol. 13 12 No. 1 2 3 May-August Sept-Dec 2017 Jan-April 2016 2016
