Halophilic microorganisms are able to grow in the presence of salt and are also excellent source of enzymes and biotechnological products, such as exopolysaccharides (EPSs) and polyhydroxyalkanoates (PHAs). Salt-tolerant bacteria were screened in the Organic Composting Production Unit (OCPU) of São Paulo Zoological Park Foundation, which processes 4 ton/day of organic residues including plant matter from the Atlantic Rain Forest, animal manure and carcasses and mud from water treatment. Among the screened microorganisms, eight halotolerant bacteria grew at NaCl concentrations up to 4 M. These cultures were classified based on phylogenetic characteristics and comparative partial 16S rRNA gene sequence analysis as belonging to the genera Staphylococcus, Bacillus and Brevibacterium. The results of this study describe the ability of these halotolerant bacteria to produce some classes of hydrolases, namely, lipases, proteases, amylases and cellulases, and biopolymers. The strain characterized as of Brevibacterium avium presented cellulase and amylase activities up to 4 M NaCl and also produced EPSs and PHAs. These results indicate the biotechnological potential of certain microorganisms recovered from the composting process, including halotolerant species, which have the ability to produce enzymes and biopolymers, offering new perspectives for environmental and industrial applications.

O Dermatofibrosarcoma protuberans (DFSP) é uma neoplasia maligna rara em ginecologia com probabilidade de recidiva local e baixo risco para metástases. Paciente com 34 anos com endometriose tratada apresentou dores na região inguinal esquerda. Reportava sensação de aumento gradual em nódulo palpável indolor e de difícil mobilização. Exérese da lesão foi realizada com hipótese diagnóstica de endometriose. A microscopia revelou neoplasia mesenquimal com proliferação de células fusiformes monomórficas e aspecto estoriforme caracterizando o DFSP. DFSP deve ser lembrado no diagnóstico diferencial das afecções da região inguinal em ginecologia, pois, apesar de ser raramente encontrado, representa uma neoplasia maligna.

Dermatofibrosarcoma protuberans (DFSP) is a rare malignant neoplasia in gynecology, with probability of recurrence and low possibilities of metastasis. A 34-year-old patient after endometriosis treatment presented pain in the left inguinal region. She reported sensation of gradual increase in a solid nodule, painless at palpation, with difficult mobilization. Exeresis was proceeded with diagnostic hypothesis of endometriosis. Microscopy revealed a mesenchymal neoplasia characterized by proliferation of monomorphic fusiform cells and storiform aspect characterizing the DFSP.DFSP must be remembered in the differential diagnosis of the affections of the inguinal region in gynecology because it represents a malignant neoplasia, although it's rare.
