“…Prominent palisaded and hyperchromatic nuclei in the basal cell layer are not seen in OOC. Many studies have also found different histochemical and immunohistochemical features in OOC from OKC, including significant differences in keratin profiles in the cyst lining epithelium [10], in collagen fibers, fibronectin, or numbers of myofibroblasts in the cyst wall [11][12][13][14], in expression of podoplanin [15], Ki-67, p63 [3], TGF-a, P53 [16], bcl-2 [17], KAI-1 [18], cell proliferating marker IPO-38 [19], calretinin [20], EMA, CEA, and involucrin [21]. These findings lead to the current concept that OOC is a different pathological entity from OKC.…”

“…Dentro de los anticuerpos empleados, se utilizó la citoqueratina CK19, una queratina de bajo peso molecular, expresada en los epitelios simples y en células basales de los epitelios no queratinizados, expresándose en las célu-las de la lámina dental, referidas como supuesto origen de los TOQ 13 . Por su parte, Bcl-2 es el producto proteico de un protooncogen, localizado en el cromosoma 18q21, que es capaz de producir un stop en la muerte celular programada (apoptosis), produciendo aumento en la supervivencia celular 14 .…”

“…Estudios previos 20 señalan que la incidencia del TOQ representa entre un 4 a un 12% de todos los quistes odontogénicos maxilares, con una incidencia media del 10% 13 . En nuestra serie los TOQ representan tan solo el 4,14% de los quistes odontogénicos, situándose nuestras cifras en el extremo inferior del rango antes señalado en la literatura 20 , si bien es posible que el número de TOQ esté sobrestimado, sobre todo en series donde no se ha contemplado un análisis inmunohistoquímico, de forma que bajo el término «queratoquístico» es probable que se hayan incluido lesiones que realmente no corresponden a TOQ.…”
