A tumor mass removed from the subcutaneous tissue of the shoulder of a dog had the light and electron microscopic features of extraneuraxial meningioma. The neoplasm probably arose from arachnoid cap cells displaced during embryogenesis.
Dermatofibrosarcoma protuberans is a locally aggressive histiocytic tumor that, on rare occasions, may metastasize to regional lymph nodes or even to distant sites. We report a dermatofibrosarcoma protuberans with lymph node involvement in a 27-year-old woman. This tumor recurred repeatedly after local excisions, and ten years after the first resection, widespread pulmonary metastases developed in the patient and she died four years later. More than 400 patients with dermatofibrosarcoma protuberans have been reported in the literature; including the present case, five of these patients had lymph node metastases, 17 patients had hematogenous spread, and three had both lymphatic and blood-borne metastases.
A method of care applicable to all forms of critical illness is presented. A patient is considered to be critically ill when he is threatened with hypoxia. According to this concept, procedures to understand and solve problems of critical care are coordinated and unified. The relevant physiology and monitoring of the components of the oxygenating system are described. The treatment of patients with impaired function of these components is described.
