Odontogenic tumors are uncommon in Brazil. Enter the email address you signed up with and we’ll email you msoqueda reset link. The cell count was performed both in the mesenchymal component of the tumor and on the epithelial component surrounding each lesion.

Primordial odontogenic tumor: An immunohistochemical profile

This is a retrospective Click here to sign up. The same group found that Syndecan-1 was intensely expressed in the mesenchyme, but not in the epithelium, by proliferating cells during the process of odontogenesis, suggesting a possible interaction of these tissues with growth factors Fig. In spite of their mosqkeda low frequency, malignant odontogenic tumors are an important cause of extensive surgical procedures in the oral and maxillofacial acalberto.

Discussion This study widely describes the immunohistochemical profile of POT. Synovial Sarcoma of the Tongue: As occurred with other immunomarkers, there were areas in the epithelium that were completely negative and some which showed clear expression Fig. The most frequent lesion was KCOT This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, moswueda, and reproduction in any medium, adalbetro the original work is properly cited.


Diagnoses were re-evaluated and the tumors classified according to the latest World Health Organization Classification of Tumors. Expression of syndecan gene is induced early, is transient, and correlates with changes in mesenchymal cell proliferation during tooth organogenesis. Glucose Transporter Glut-1 is found in normal cells, such as erythrocytes and endothelium at the blood-brain barrier in perineural cells, and in the basal layer of oral epithelium and epidermis.

Gender and tumor site analyses were done using the binomial test.

Odontogenic tumors: A retrospective study of four Brazilian diagnostic pathology centers

Syndecan-1 plays a role in epithelial maturation, and it has been consistently observed that the degree of epithelial differentiation is directly associated with its expression Add Social Profiles Facebook, Twitter, etc.

Twelve cases were treated with surgery alone, 3 patients with surgery and adjuvant radiotherapy, 1 had neoadjuvant chemotherapy followed by surgery, 1 had neoadjuvant chemotherapy, surgery and postoperative radiotherapy, 1 with surgery and adjuvant chemotherapy, 1 with surgery followed by adjuvant chemotherapy and radiotherapy and one patient rejected treatment.

Immunophenotypic studies were performed in nine of these cases.

In relation to sociodemographic data, a higher proportion of males was affected with OT and the average age at diagnosis was 35 years, which is in agreement with the results of Simon et al.

MOC has been proved to be an advantageous marker at signaling epithelial cell differentiation. The private laboratory showed a greater frequency of OT and oral lesions than the other laboratories, possibly because this center is specialized in oral pathology, whereas INCA is the primary cancer referral center for Brazil, seeing a large number of patients with oral lesions but predominantly with malignancies such as oral squamous cell carcinomas.

With previous written informed consent, 20 patients The selected markers provide new and valuable information for a better understanding of the possible histogenesis and biological behavior of this entity.
