Morphological and ultrastructural methods for Pneumocystis.

Pneumocystis is a eukaryotic unicellular microorganism with marked fungal affinities. All known life cycle stages of this parasite were observed in the lung of mammals. The cystic forms of this microorganism may be observed microscopically by using stains with affinity for the components of their relatively thick cell wall.

[Thyroid autonomous nodule. Surgical treatment and postoperative outcome, retrospective study of 102 cases (author's transl)].

Follow-up of 102 patients operated upon for autonomous thyroid nodules is reported. Retrospective study of operative findings and aftermath of surgery clearly demonstrates that the patho-physiological concept of autonomous nodule does not snugly fit practical problems experienced with the management of such patients. The autonomous nodule can be a malignancy.

[A gonadoblastoma in a true hermaphrodite. A case history (author's transl)].

The gonadoblastoma has been found in patients with gonadodysgenesis of a pure or mixed variety or who have male pseudo-hermaphroditism. This gonadic tumour is rarely found in true hermaphroditism. This case history would seem to be the first that has been reported in France.
