Odontogenic Tumour Patterns- An Introspective Analysis

Calcifying Epithelial Odontogenic (Pindborg) Tumor in a Child: A Case Report and Literature Review

“…Intraosseous involvement is another feature that is associated with higher chance of recurrence as compared to extraosseous tumor [27, 33]. In contrast, the presence of calcification and amyloid-like material indicates more differentiation and a lower likelihood of recurrence [34]. Malignant transformation and metastatic spread is extremely rare.…”

Ameloblastic fibroma to complex composite odontome – a continuum? – a review

“…The size of the lesion is usually small, measuring few millimetres; exhibits equal gender predilection; 3,4,10,11,14-20 except few case series where male predominance are reported 4,8 . Posterior region is the commonest site irrespective of maxilla or mandible.…”

“…1 They range from hamartomas to neoplasms, which in turn may vary from benign to malignant. 2,3,4 The classification of odontogenic tumours is a dynamic one, due to the change in understanding of their nature and behaviour based on newer molecular and genetic studies. 1,4,5 Mixed odontogenic tumours are composed of neoplastic odontogenic epithelial as well as odontogenic ectomesenchymal components, and categorized by WHO in their classification of Odontogenic tumours (2005) under "Tumours of odontogenic epithelium with odontogenic ectomesenchyme".…”

The lesions under this group are ameloblastic fibroma (AF), ameloblastic fibro dentinoma (AFD), ameloblastic fibro odontoma (AFO), odontoma, odontoameloblastoma, calcifying cystic odontogenic tumour (calcifying odontogenic cyst or COC) and dentinogenic ghost cell tumor.…”

Controversies in Odontogenic Tumours: Review

“…6,7 In 2016, Singh et al proposed a classification for odontogenic tumours based on histopathological patterns; unfortunately, some of the classified lesions had overlapping histological features, thus limiting their diagnostic utility. 8 The current review article categorises benign odontogenic lesions as either epithelial, mixed or mesenchymal lesions while malignant lesions are divided into carcinomas, sarcomas and carcinosarcomas.…”
