The ovaric lobule: a histoembryological unit.

Microscopic study of newborn female ovaries showed a constant and characteristic architectonic pattern on the surface area of the organ cortex. This pattern consisted of units that have been called "ovaric lobules" and that are made up of the various cellular types involved in the formation of the gonad (oocytes, cells derived from surface epithelium and connective-vascular elements). These structural units might be the site where synchronization or coordination for development and maturation of the successive groups of follicles occurs in post-natal life.

Papillary carcinoma of the thyroid gland with lipomatous stroma: report of a peculiar histological type of thyroid tumour.

The author reports a case of a 53-year-old woman with a slowly growing thyroid papillary carcinoma. Microscopically the presence of adult adipose tissue was detected in numerous papillae. The recognition of this histological type as a new variety of papillary carcinoma is proposed.

[Basal cell nevus syndrome. Presentation of 2 cases. 1 associated with medulloblastoma].

A case of nevoid basal-cell carcinoma syndrome in a four years old girl with preceding familiar history is reported. In her epithelioma father numerous basocellular, milia cysts, mandibular cysts, dentition disorders, brain falx calcifica ted and hiperkeratosis of the sole of the feet were described. Clinically, the girl presented initial migraine and vomits together with macrocephalus, bossing forehead, hypertelorism, physical disorders, retarded maturation, "keel" thorax, genu recurvatum, hallux valgus, hammerfinger, pigmented nevus and hyperkeratosis of the sole of the feet.

Ectopic adrenal cortex in neonatal liver.

A small nodule of tissue, found deep within the liver parenchyma of a 3-day-old neonate, proved to be composed of adrenal cortical tissue of both fetal and adult types. Whilst ectopic adrenal tissue is widely recognized in many sites in the body, an intrahepatic localization does not previously appear to have been recorded. The possible mechanisms involved in the ectopia are discussed as is the potential relevance to neoplastic change.

[ORF. Epidemiological, histopathological and clinical considerations, apropos of a case].

The observation belongs to a 22 year-old man, who presented a lesion in the index finger of the right hand, with a nodular induration, which later turned into an ulcer and was cured in a month and a half. In the beginning it was painless, becoming painful after the third week. He was given a treatment of a simple topical application.
