cystadenoma/phosphatase

Sertoliform cystadenoma of the rete testis represents an uncommon benign tumour. They appear in patients from 26 to 62 years of age. We describe a case of a 66-year-old man with a tumour in the area of the epididymal head. The tumour markers were not increased. Under the assumption of a malignant

We report a case of prostatic cystadenoma in a 45-year-old man with the complaint of urinary retention. The large mass was palpated on rectal examination. The tumor was localized in the position of the left lobe of the prostate and was seen as multi-ocular on computerized tomographic (CT) scan. The

To our knowledge, there are currently no reports in the literature that discuss the fine structure of the striated ducts of the human parotid gland. Papillary cystadenoma lymphomatosum (Warthin's tumor) is a benigh neoplasm found almost exclusively in the parotid gland that represents about 16% of

An unusual case of a hepatobiliary cystadenoma caused severe abdominal pain and obstructive jaundice by rapid enlargement in a woman aged 73 years. Magnetic resonance imaging revealed a 12 cm cystic lesion in the left medial segment of the liver and dilatation of the intrahepatic bile ducts. The

Two examples of large, multiloculated, cystic tumors that arose within the pelvis in men of 28 and 37 years of age are described. The tumors were composed of glands and cysts lined by prostatic-type epithelium lying in a hypocellular fibrous stroma. The prostatic nature of the lesions was confirmed

A monoclonal antibody (NDOG2) against placental alkaline phosphatase (PLAP) in ovarian cancer has been used in three ways by the Bristol University Department of Obstetrics & Gynaecology. First, in an indirect immunoperoxidase technique, NDOG2 demonstrated positive standing in 64% of 56 ovarian

Biliary mucinous cystadenomas (BMC) of the liver are rare benign cystic tumors, however an estimated 20% undergo malignant transformation. They have recently been redefined as mucinous cystic neoplasms in the 2010 WHO classification. The preferred treatment is through radical resection, as there are

The mitogen-activated protein kinase phosphatase-1, MKP-1 (CL100) is involved in inactivation of MAP-kinase pathways, regulation of stress-responses and suppression of apoptosis. We investigated expression of MKP-1 in 90 cases of primary ovarian tumors, 11 normal ovaries as well as 4 ovarian

An 80-year-old man was admitted to our hospital with the chief complaint of urinary retention. On physical examination, a large tumor was recognized in pelvic cavity. Serum levels of prostatic acid phosphatase and gamma-seminoprotein were elevated. Anterior pelvic exenteration was performed because

The immunohistochemical expression of PLAP and vimentin was assessed in 23 benign, 6 borderline malignant and 31 malignant epithelial ovarian neoplasms. PLAP and vimentin were expressed in some benign (3/23 and 5/23 respectively) and borderline malignant (2/6 for both markers) tumours and they were

A cystic tumor composed of atypical glands in a cellular stroma arose in the pelvis of a 49-year-old man. Two years later an identical tumor was again excised from the pelvis. Morphologic, immunohistochemical and ultrastructural studies indicate that this neoplasm arose in the seminal vesicle,

OBJECTIVE The aim of this study was to investigate the expression of vascular endothelial growth factor (VEGF) by neoplastic cells in serous ovarian cystadenocarcinoma in relation to proliferation as determined by mitotic activity and to FIGO stage. METHODS Formalin-fixed, paraffin-embedded archival

The medical records of 7 hypercalcemic cats with primary hyperparathyroidism were evaluated. Mean age was 12.9 years, with ages ranging from 8 to 15 years; 5 were female; 5 were Siamese, and 2 were of mixed breed. The most common clinical signs detected by owners were anorexia and lethargy. A

Thirty-five ovarian tumors were examined (7 granulosa-cell tumors, 2 thecomas, 4 dysgerminomas, 6 mucinous cystadenomas, 10 serous cystadenomas, 2 adenocarcinomas, 3 Krukenberg tumors and 1 early embryonic tumor). The granulosa-cell tumors showed high activity of alpha-glycerophosphate
