Pleomorphic adenoma of the nasal septum and its relationship with Epstein-Barr virus.
ABSTRACT Pleomorphic adenoma is the most common benign tumor of the major salivary glands, especially of the parotid gland. It is much less common in the minor salivary glands of the oral cavity, and it rarely occurs in others sites in the head and neck. Even if virus involvement in salivary glands tumor has been many times discuted, the etiology of this tumor keeps being unknown. As compared to other nasal tumors, we tried to prove if Epstein-Barr virus (EBV) could be involved in the development of pleomorphic adenoma in this particular nasal localization.
Three cases of pleomorphic adenomas of the nasal septum (two women and a man in age of 23-59 years) were retrospectively studied. All had positive rate of EBV-related blood antibodies. All the patients had undergone endoscopic surgery to remove the complete tumor. We used hybridation technique in the search for EBV-DNA in the three tumors.
We had positive EBV-DNA detection in the tumor in one case, which seemed to prove relationship between pleomorphic adenoma and this virus. The literature concerning the subject is reviewed in order to explain EBV involvement in the development of such tumors in this particular localization.

ABSTRACT: A case of pleomorphic adenoma of the parotid gland was reported. Pleomorphic adenoma is the most common benign tumor of the major salivary glands. A review of the literature confirms that this kind of tumor is less common in the minor salivary glands. We described statistic population, types of the diagnostic, treatment and clinical course of pleomorphic adenoma of the parotid gland. We encountered such a tumor in a 55-year-old woman who was admitted to our Hospital. The only symptom was significant face deformation, growing for 30 years. The tumor was located under the right side of the face and was removed surgically. No complications were observed in the postoperative course but paresis of the facial nerve occurred. The patient was discharged from the hospital with the recommendation of facial muscles rehabilitation. After the two months from the surgery, paresis was diminished. Afterwards contact with the patient got lost. Pleomorphic adenoma is the most common benign tumor of the major salivary glands. Surgery is the main method of the treatment. The most common complication is paresis of the facial nerve.Otolaryngologia polska. The Polish otolaryngology 01/2008; 62(2):195-8.
