One familial case of ectodermal dysplasia of the Clouston's type is reported. The clinical picture consisted of hypotrichosis and dysonychia with normal sweating. The disease follows dominant autosomal transmission. Histologically, keratin was slightly abnormal. The biochemical study of keratin of hair and nails showed diminished cysteine.
Malignant hypercalcemia due to the association of hyperthyroidism and hyperparathyroidism is rare. We report a case with a fatal course in spite of surgical treatment of both lesions. Death occurred seven days after the operation due to ventricular tachycardia, in spite of return to normal of the calcemia, the serum phosphorus, the serum electrolytes and relief of the thyro-toxicosis. There is a great deal of histopathological evidence for the association of a toxic parathyroid carcinoma and a thyroid adenoma.
The ultra-structural of a C-cell carcinoma of the thyroid confirms previous data: the cells are slender, with a large nucleus. The Golgi apparatus is well developed. Granules in striking abundance are seen in every part of the cytoplasm: their diameter is 85 - 250 mmu.

A 34 years old woman had a hysterectomy for persistent menorrhagias. The uterine vault was covered by an exophytic grape-like tumor measuring 10 cm in length, formed by little red nodules with focal adjacent lesions. This tumor is cytologically benign and of leiomyomatous nature on the ultrastructural study. The questions concerning diagnosis and prognosis of this case are discussed.
