The purpose of this study was to report an extrafollicular adenomatoid odontogenic tumor in the mandibular anterior region in a patient. A 15 year-old female with a painless swelling in the mandibular anterior region was referred to our clinic. Fine needle aspiration yielded no fluid. Periapical, panoramic and computer tomography scans showed circumscribed radiolucent area with fine calcificati...

The combined epithelial odontogenic tumor is known to be an uncommon lesion characterized by the synchronous presentation of typical histological features of adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, or Pindborg tumor. Combination between other types of odontogenic tumors has occasionally been reported in the literature. In this work we report 2 cases of adenomatoi...

INTRODUCTION The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxi...

Adenomatoid tumor is an uncommon benign neoplasm of mesothelial differentiation that distinctively arises in and around the genital organs. In rare instances, it has been described in extragenital locations. There have been only two reports documenting its occurrence in the anterior mediastinum, and no reports documenting its occurrence in the posterior mediastinum. We report the first case of ...

Malignant mesotheliomas of the testis arise from the tunica vaginalis, formed from the evagination of the abdominal peritoneum into the scrotum. It is an extremely rare tumor representing 0.3% to 5% of all malignant mesotheliomas. We presented an interesting case of 68-year-old male with swelling and slightly painful in the right scrotum. Histologically, the lesion were composed of small tubula...

A case of uterine adenomatoid tumor in a 47-year-old female was studied with both light and electron microscopes. The tumor was circumscribed, 2.5 cm in diameter, and located in the posterior wall of the uterus. In light microscopy, tumor cells showing "signet-ring" appearance arranged in cords or tubules. Hyaluronidase-sensitive acid mucopolysaccharide was present in the cells and luminal surf...

splenogonadal fusion is a rare congenital malformation whereby the splenic tissue is found attached or surrounded by the testis, and presents in both continuous and discontinuous forms. splenogonadal fusion may be misinterpreted as a primary malignant testicular or an adenomatoid tumor. knowledge about the existence of such an entity is essential in order to preserve the testis during surgical ...
