[Catamenial pneumothorax. Case report and review of the literature]. / Pneumothorax cataménial. A propos d'un cas et revue de la littérature.

Catamenial pneumothorax is a clinical variant of spontaneous pneumothorax. Its etiology is attributed either, generally, to endometriosis involving the diaphragm, or to prostaglandin-induced bronchiolar constriction. Clinically, it coincides with the onset of menstruation and resolves during the subsequent days. Treatment is currently based upon progestational agents and antigonadotrophins.

[Catamenial rectal bleeding and sigmoid endometriosis]. / Rectorragie cataméniale et endométriose sigmoïdienne.

We describe a case of menstrual rectal bleeding due to sigmoid endometriosis. The history led us to the diagnosis and since a small biopsy of the lesion and scanning could not help us to a conclusive diagnosis we carried out histological examination of a piece removed at operation. This case has led us to estimate the incidence, the difficulties of diagnosis and the present therapeutic measures.
