1. Dermatomyositis: analysis of 109 patients surveyed at the Hospital das Clínicas (HCFMUSP), São Paulo, Brazil
BACKGROUND: Dermatomyositis affects striated muscles, skin and other organs. OBJECTIVE: To characterize the disease from January 1992 to December 2002, assessing its classification, cutaneous and systemic manifestations, and also laboratory results, therapeutic and prognostic findings compared to those in the literature. METHODS: Data were obtained from

2. Incidência de Neoplasia Intraepitelial Conjuntival em Pterígio / Incidence of Conjunctival Intra-epithelium Neoplasia in Pterygium
Introdução: Pterígio e neoplasia intraepitelial córneo-conjuntiva (NIC) têm sido bastante estudados como lesões relacionadas. Projeto: Estudo prospectivo conduzido com pacientes da Santa Casa de Campo Grande-MS, Brasil. Metodologia: De março a julho de 2009, pacientes consecutivos com pterígio indicados para cirurgia foram estudados. Dados clínicos

3. Disgerminoma bilateral e hiperplasia endometrial cística com piometra em cadela = Bilateral Dysgerminoma and Cystic Endometrial Hyperplasia with Pyometra in a bitch / Bilateral Dysgerminoma and Cystic Endometrial Hyperplasia with Pyometra in a Bitch
Background: Ovarian tumors are considered rare both in dogs and cats. Germ cell neoplasms correspond to approximately 15% of the cases and can be classified into dysgerminomas, teratomas and teratocarcinomas. Reports of bilateral dysgerminoma in dogs and cats are rare. The aim of this work was to describe a case of bilateral dysgerminoma and cystic endometri

4. Tumor estromal gastrointestinal de intestino delgado
Stromal tumors of the gastrointestinal tract (gists) represent relatively rare lesions that arise from connective tissue elements located along the entire length of the gut. They were initially identified by immunohistochemical investigation, proving their origin from nondifferentiated mesenchymal cells. Only a minority of this lesions, mainly those confined

5. Hyaluronate and invasiveness of the rabbit V2 carcinoma.
We propose that hyaluronate, a major component of extracellular matrices through which cells migrate during embryonic tissue development and in regenerative processes, is also concentrated in the environment through which neoplastic cells invade local host tissues and may facilitate this process. The hyaluronate content of invasive V2 carcinoma grown in rabb

6. Immunohistochemical identification of tumours of adipocytic differentiation using an antibody to aP2 protein.
AIM--To determine whether aP2 expression is a useful diagnostic marker in soft tissue tumour pathology. METHODS--A polyclonal antibody to aP2 was used to investigate the immunohistochemical expression of this protein in benign and malignant tumours of adipocytic differentiation and a wide variety of other neoplasms. RESULTS--aP2 was only expressed by lipobla

7. Primary biphasic synovial sarcoma of the orbit.
Synovial sarcoma is one of the most common soft tissue malignancies of adolescents and young adults. Despite its name, it is no longer thought to be histogenetically derived from the synovium. What seems to be the first case of synovial sarcoma to arise in the orbit presented in a 21 year old woman as a slowly enlarging subconjunctival mass. Although this tu

8. Fibronectin and type III collagen in epithelial neoplasms of gastrointestinal tract and salivary gland.
The distribution of fibronectin (FN) and collagen type III (IIIC) have been compared in a series of epithelial neoplasms from the gastrointestinal tract and salivary gland. The difficulty of distinguishing between FN of epithelial and fibroblastic origin is emphasised and evidence is presented for the validity of this distinction. In carcinomas FN was someti

9. Adenoid basal carcinoma of the cervix uteri
This paper describes a case of adenoid basal carcinoma of the uterine cervix, occurring in a woman aged 78 years. In view of the rarity and the limited knowledge of this group of neoplasms, details of the clinical history, the histological appearances, and the histochemical reactions are presented. An attempt is made to define the histogenesis of the tumour

10. Two malignant pleural mesotheliomas with unusual histological features.
Morphologically, mesotheliomas may be composed of epithelial and/or sarcomatous elements with various patterns, such as tubular, papillary, tubulopapillary, and diffuse epithelial or mixtures of these. Two cases are descirbed in which, in addition to typical mesothelioma, there was cartilage with foci of calcification and ossificated with the mesothelioma, w

11. Use of antisera to epithelial membrane antigen for the cytodiagnosis of malignancy in serous effusions.
A new human antigen, designated epithelial membrane antigen (EMA), has recently been described on surface membranes of a wide variety of normal epithelium but not on connective tissue cells. The antigen is only weakly expressed on normal or reactive mesothelium. Increased expression of the antigen has been observed in most neoplasms of epithelial origin and
