[Menstruation-associated (catamenial) pneumothorax and catamenial hemoptysis].

We report on 2 patients with catamenial pneumothorax and one patient with catamenial hemoptysis. The pathogenesis of these diseases is not clear, and intrathoracic endometriosis is often assumed. Catamenial pneumothorax is rare and differs from primary spontaneous pneumothorax in its prevalence in the fourth decade and in mainly multiparous women, its recurrent and almost exclusively right-sided occurrence within 72 hours of the beginning of menstruation, and the generally small size of the pneumothorax.

[Microangiopathic hemolytic anemia, erythrophagocytosis and consumption coagulopathy in vinyl chloride-induced hemangiosarcoma of the spleen and liver].

A case of angiosarcoma of the liver and the spleen following vinyl chloride exposure is described. The main symptoms in clinical diagnosis were microangiopathic hemolysis, disseminated intravascular coagulation, hepatosplenomegaly and exposure to vinyl chloride thirty years ago. It is the first case in which liver and spleen are involved in angiosarcoma due to vinyl chloride exposure.

Pathogenesis of thyroid nodules in multinodular goiter.

Pathogenesis of nodule formation was studied in over 100 nodular goiters from a subendemic area. 60 surgical specimens were autoradiographed. Only one classical, well-encapsulated adenoma was detected.
