Paratesticular adenomatoid tumor (morphologic and immunohistochemical study of 9 cases)

Almost all solid scrotal masses are malignant tumors. Among these, tumors originating from mesothelium, are usually benign. Adenomatoid tumors constitute the majority of the solid tumors with mesothelial origin. Although adenomatoid tumor can be seen at all ages, it is mostly common in the third and fifth decades. These tumors, which are treated surgically, may pose some diagnostic difficulties

Does HepPar-1 immunoexpression have a role in differential diagnosis of periampullary cancer?

Aims: Histological subtyping of periampullary carcinomas is considered as a criterion for prognosis and therapeutic implications of these tumours. We assessed the immunoexpression rates of HepPar-1, CDX2 and MUC2 antibodies in different subtypes of periampullary adenocarcinomas (PAC), intestinal and pancreatobiliary, in order to assess their impact on differential diagnosis of this group of cancers. The expression of antibodies was also measured in ductal adenocarcinoma of the pancreatic head (DAPH)

Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) of the penis

Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) of the penis has been very rarely defined. We report a case of a 19-year-old patient with a tumor, localized in the dorsal side of penis, composed of small round cells with diffuse membranous mic-2 (CD99) immunopositivity. The patient was treated with multiagent chemotherapy and radiotherapy

Malignant mesothelioma of the tunica vaginalis testis: a case report and review of the literature

Most often, mesotheliomas involve the serosal membranes of the pleura and peritoneum. Sometimes, mesothelial proliferations are identified in other locations. A mesothelioma, within the tunica vaginalis of the paratesticular region is rare but often fatal malignancy of the male genitalia. Despite aggressive surgical and systemic therapy the prognosis remains poor with only rare long-term survivors. We report a case of malignant mesothelioma of the tunica vaginalis in 45-years-old and review of the literature is presented

Serum amyloid A (SAA) in induced sputum of asthmatics: A new look to an old marker

Background: Some cellular and soluble markers of inflammation in induced sputum have been used for studying airway inflammation in asthma. The aim of this study was to assess the usefulness of systemic inflammation marker serum amyloid A (SAA) in blood and induced sputum to monitor the airway inflammation in asthmatic patients
