Registro de um caso de condrossarcoma intracraniano primário, sendo discutidos aspectos clínicos, histológicos, radiológicos e terapêuticos e dando-se ênfase a aspectos neurorradiológicos que permitem o diagnóstico diferencial com outros tumores intracranianos, em particular, os cordomas e meningiomas.

A case of intracranial chondrosarcoma is reported. Its diagnosis can be suspected through the findings of a paraselar avascular tumor, sometimes with inespecific calcifications, visualized as a isodense and contrast-enhancing mass by computed tomography, as observed in the case. Differential diagnosis may be difficult with chondromas and meningiomas. Surgical ressection is the treatment of choice, with good results.

Os Autores relatam caso de mucormicose subcutânea em paciente apresentando quadro clínico e laboratorial de ceto-acidose diabética. São descritos os aspectos clínicos, micológicos e histopatológicos, salientando-se a importância da obtenção do diagnóstico rápido para a instituição da terapêutica precoce. São revistas as formas clínicas da mucormicose e as principais condições associadas, bem como os possíveis mecanismos que facilitam a infecção por Mucorales em pacientes com ceto-acidose diabética. O isolamento de R. oryzae do ambiente onde o paciente esteve internado, sugere tratar-se provavelmente de infecção hospitalar adquirida por contaminação venosa através de esporos do fungo.

The Authors present a case of subcutaneous mucormycosis occurring in a patient with clinical and biochemical evidence of diabetic ketoacidosis. The clinical, mycological and histopathological features are described, emphasizing the relevance of a rapid diagnosis in order to stablish early treatment. The clinical forms of mucormycosis and the main associated conditions are briefly reviewed as well as the most probable conditions which may lead to the enhanced susceptibility to infection in the diabetic patient in ketoacidosis. The recovery of Rhizopus oryzae from the air of the room of the patient suggests a nosocomial infection acquired through contamination of venous puncture site by air borne spores.

E relatado um caso de arterite temporal em paciente com crises de cefaléia paroxística associadas a síndrome depressiva e, na última crise, a aumento de volume das glândulas salivares. Biopsia de artéria temporal superficial mostrou aspecto típico de arterite, com células gigantes mononucleadas. A cefalalgia e o aumento de volume das glândulas salivares regrediram mediante a administração de corticoesteróides.

A case of temporal arteritis associated with depressive syndrome and enlargement of salivary glands is reported. Biopsy of the superficial temporal artery showed arteritis with multinucleated giant cells. After corticosteroid therapy the headache and the enlargement of the salivary gland improved rapidly.
