Congenital cystic adenomatoid malformation of the lung is rare in adults. We present a 51-year-old man with recurrent lower respiratory tract infections and intermittent febrile episodes for more than 10 years. Multiple cavitary lesions with fluid accumulation were seen in the right lower lobe of the lung on radiography and computed tomography of the chest. Wedge resection of the right lower lo...

background: solid ameloblastoma (sab) is an invasive tumor which infiltrates adjacent normal tissues. adenomatoid odontogenic tumor is a noninvasive tumor and never infiltrates surrounding normal tissues. the purpose of this study was to determine the biological behavior of these two epithelial odontogenic neoplasm by detecting ki-67 and bcl-2, which are mitotic and anti apoptotic markers respe...

We describe a 10-year-old boy with a rare large multicystic pulmonary chondroid hamartoma in the right lower lobe presenting with severe respiratory distress. The radiological evaluation showed a large multicystic lesion in the right lower lobe with pneumothorax. Commonly, pulmonary hamartomas are asymptomatic, small in size, and are diagnosed incidentally in adults. Our case is highly unusual ...

Adenomatoid tumors are neoplasms of mesothelial origin, usually occurring in the male and female genital tracts. Extragenital localization sites such as adrenal glands are rare but have been reported. When found in the adrenals, they represent great clinical, radiological and pathological diagnostic challenge, with wide range of differential diagnoses to be considered. We present a case of a 30...

Primary peritoneal tumors share a common anatomical site and therefore their clinical manifestations are very similar. When masses detected, the tentative initial diagnosis is secondary to metastatic disease, which has been determined most frequently in cavity. However, primary should always be included differential diagnosis. Among malignant neoplasms, mesothelial have identified (malignant me...

BACKGROUND Origin of adenomatoid odontogenic tumor (AOT) has long been a controversy, and the issue of it being a neoplasm or hamartoma was a subject of debate for a long time. Earlier it was grouped under a mixed group of odontogenic tumors considering the varying degrees of inductive changes. Recently, the WHO classification states that the presence of hard tissue within AOT was not due to in...
