calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

results: the only significant difference was the older age of the malignant group vs. benign group (p = 0.001) regarding demographic findings. as concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (p = 0.001). additionally, data analysis of patients as a total group showed that specificity (96.4%), posit...

odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

primary fallopian tube carcinoma is a rare tumor that histologically and clinically resembles epithelial ovarian cancer. here we introduce a case of tubal carcinoma in a postmenopausal woman. the diagnosis of primary fallopian tube carcinoma is rarely considered preoperatively and is usually first appreciated by the pathologist. because of low frequency of tubal carcinoma, there are few systemi...

conclusions hpv type 16 was detected in only 9.67% of malignant epithelial tumors. it appears that hpv infection plays a relatively minor role in the pathogenesis of ovarian carcinomas. results out of the eight cases with functional cysts only one case (12.5%) expressed hpv. no hpv expression was seen in cases with benign and borderline tumors. out of the 31 cases with one malignant surface epi...

Ovarian cancer is the most lethal gynecologic malignancy. The surface epithelial tumor is the most common type of ovarian cancer. Among these, the mucinous tumors account for 10-15% of ovarian tumors. Mucinous ovarian tumors are among the most difficult ovarian neoplasms for surgical pathologists to interpret. Mucinous tumors sometimes coexist with other surface epithelial tumors. Therefore, ma...

calcifying epithelial odontogenic tumor (ceot) is a rare benign, but locally infiltrating odontogenic neoplasm. it accounts for less than 1% of all odontogenic tumors. this is a case report of recurrent ceot in the maxilla. a 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. it is of particular concern because of its anatomic location in the m...
