[Mediastinal hydatid cyst. Reflections on a case study]. / Quisto hidático do mediastino. A propósito de um caso clínico.

Hydatid cyst is a zoonotic cycle parasitic infection caused by Echinococcus granulosus tapeworm, whose larvae infect man as an intermediate host. It is one of the most serious lung diseases caused by helminths. It is rare to find it in the mediastinum; < 1%. The primitive, or seemingly primitive, location is due to the parasite in the cellular tissue of the mediastinum. The authors report the case of a sixteen year old male, admitted to the E.R. for left posterior chest pain which had spread to the upper left limb.

[Lung cancer and cutaneous metastasis]. / Cancro do pulmão e metastases cutâneas.

The authors did a review of patients with lung neoplasms and cutaneous metatization diagnosed in the period from 1999 to 2004 and followed in the Pneumologic Oncologic department of the Hospital Sousa Martins (H SM). We have analysed the following variables: sex, race, hystologic diagnosis, clinical stage, therapeutics, impact of the appearance of cutaneous metastization and survival time. Five of the 114 patients with lung neoplasms (4.3%), presented with cutaneous metastization, two males and three females with an average age of 69 years. In one of the patients the cutaneous lesions were synchronic, and in the others were metachronic. The most prevalent histologic type was the adenocarcinoma. The average survival time after the cutaneous metastization was 3.8 months. The results are compared with others present in the world literature.
