Calcifying epithelial odontogenic tumor is a benign neoplasm, but its local destructive potential may lead to the formation of major bone defects. Microscopically, there are some histological variants. Among them, we highlight the clear cell variant due to its more aggressive behavior and a higher incidence of relapse. In this context, it is pertinent to describe the clear cell variant of calci...

Keratin is an intermediate filamentous protein generally found in the surface epithelium (Clausen et al., 1986; Steinert et al., 1995; Coulombe et al., 1990; Neville et al., 2002). Their role is to protect the underlying structures, which is one of the prime functions of surface epithelium (Tencate, 1998). The keratin synthesis reflects the differentiation level of normal epithelial cell as wel...

Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...

We reviewed the clinicopathological characteristics of 13 cases of calcifying epithelial odontogenic tumour (CEOT) (Pindborg tumour) diagnosed in the Division on Stomatology, Institute for Medical Research, Kuala Lumpur, over a 29-year period. There were eight female and five male patients. These consisted of eight (61.5 per cent) Malays, three (23.1 per cent) Chinese, one (7.7 per cent) Indian...

The experiments reported here were undertaken to compare the sensitivity of some rat tissues to relative or absolute vitamin A deficiency and to prophylactic doses of the vitamin. That there must be considerable differences in the requirements of various tissues and processes in the rat for vitamin A is suggested by the computed requirements of the entire animal found in the literature, based o...

An extensive study of the relationship between smoking and calculus deposition in nearly 6,000 men was undertaken by Pindborg,1 in 1949. Chilton,2 in 1967, used these data to illustrate the familiar test for association in a contingency table but noted that the analysis was limited because, although it established the existence of a significant association between smoking and calculus depositio...
