Introduction: Calcifying epithelial odontogenic tumor (CEOT) is a rare benign, but locally infiltrating neoplasm which accounts for less than 1% of all other tumors. The often associated with impacted teeth and twice as prevalent in the mandible. Dentigerous cysts are developmental cysts, commonly manifesting second third decades life. A greater incidence men women ratio 1.6:1 61.4% or unerupte...

cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. the bacterial colonies were seen around the parabronchial spaces of the lung tissue. i...

This report describes the surgical therapy, clinical course and morphological characteristics of an adenomatoid odontogenic tumor that developed in the maxilla of a 16-year-old patient. The cystic tumor filled the maxillary sinus and was removed with the retained tooth. Healing was uneventful and no local recurrence was observed during a two-year period of follow-up control. The tumor showed im...

Congenital cystic adenomatoid malformation, currently referred as congenital pulmonary airway malformation (CPAM), is one of the rare lung malformations seen in adults. We report a case of a 59-year-old male with a chronic cough and hemoptysis that was not amenable to bronchial embolization. Further work up revealed cystic changes with fungal ball and type 1 CPAM. Patients with this condition w...

Pulmonary localized hamartomas were first reported in 1906 by Hart(1). Hamartoma is the most common benign neoplasm to occur in the lung. Histologically, the lesions consist of a combination of cartilage, connective tissue, smooth muscle, fat, and respiratory epithelium. Malign transformation is rare (2,3). Pulmonary hamartomas occur more common in males. However, some authors reported male/fem...

Hamartomas are disorganized but benign masses composed of cells indigenous to the involved site. They have been reported in almost all organs but are rare in the head and neck region, especially the pharynx. We describe the case of a six-month-old male infant who presented with acute respiratory symptoms due to a pedunculated polypoid mass arising from his left palatine tonsil. He underwent a t...

Adenomatoid tumors of adrenal gland are rare, asymptomatic neoplasias, with benign behavior, and usually are diagnosed incidentally. We report a case of a voluminous adenomatoid tumor of left adrenal gland in a 42-year old man who sought evaluation because of renal colic due to left nephrolithiasis. During the investigation, a tumor localized in left adrenal gland was identified by ultrasonogra...

Quigley, James C, and Hart, William R.: Adenomatoid tumors of the uterus. Am J Clin Pathol 76: 627-635, 1981. Adenomatoid tumors arising in the uterus are not well-recognized and are sometimes mistaken for other benign or malignant neoplasms. This study is a clinicopathologic analysis of 12 uterine adenomatoid tumors. Characteristically, they were small nodular lesions (mean diameter 2.1 cm) in...
