Three cases of symptomatic Rathkes' cleft cyst are described. Case 1. A 51-year-old man was admitted to the hospital for evaluation of intermittent headache, in April, 1985. He was neurologically free, but skull films disclosed a ballooning of the sella with thinning of the dorsum sellae. CT scan showed enlargement of the sella, but no abnormal density area in the sellar region. MRI revealed a round mass with high signal intensity located just posteriorly to the pituitary body. By a transsphenoidal approach, a thin-walled cyst was found at the posterior portion of the sella. Turbid mucinous fluid and the capsule of the cyst were subtotally removed. Histologic section of the specimen demonstrated that its wall was composed of a loose fibrous tissue lined by a single layer of ciliated cuboidal epithelium containing some goblet cells. Electron microscopy showed ciliated cuboidal cells, cells with microvilli, cells with light and large granules, and basal cells abutting on the basal lamina. Case 2. A 33-year-old female was referred to the hospital with complaints of severe headache and decreased visual acuity 0.02 in the left and 0.1 in the right, in July, 1985. Visual field examination revealed bitemporal hemianopsia. She had amenorrhea, galactorrhea and polyuria. CT scan and metrizamide CT cisternography detected a low density mass in the suprasellar region. Endocrinological studies disclosed hyperprolactinemia with partial hypopituitarism. She had a right frontal craniotomy and a suprasellar cyst was subtotally removed. Histologically, a cystic wall was lined by pseudostratified columnar epithelium supported by a loose fibrous tissue.(ABSTRACT TRUNCATED AT 250 WORDS)

Radiologic studies of the sella turcica have been performed in 355 patients operated on for prolactinomas. According to our classification, the grading of the sella in 300 females was normal in seventeen, grade I in one hundred and seventy-eight, grade II in eighty-seven, grade III in nine and grade IV in nine. A suprasellar expansion was evidenced in twenty-four of these patients. In 55 men, the sella was of grade I in eight, grade II in thirty-nine and grade IV in eight. Twenty-three had a suprasellar expansion. The early radiological diagnosis of a prolactin-secreting microadenoma became important when the hypophyseal origin of the clinical syndromes associated with hyperprolactinemia was demonstrated. Prolactinomas can usually be diagnosed by polytomography when they have reached 4 mm in size. Subtle bony changes such as cortical thinning, lateralized blistering or bulging of the floor are reliable radiological signs when associated with a biologically confirmed clinical syndrome.

A 7-year-8-month-old boy with cardiofaciocutaneous syndrome caused by the D638E mutation of the B-Raf proto-oncogene (BRAF) presented with new-onset seizures. He was incidentally found to have advanced Tanner staging on physical examination. Hormonal testing revealed pubertal levels of gonadotropins and sex steroid hormones. On brain imaging, a lack of visualisation of the posterior pituitary bright spot was observed, in addition to mild thinning of the corpus callosum and the lateral gyri of the cerebellar hemispheres. A diagnosis of idiopathic central precocious puberty was made and the patient was started on leuprolide depot treatment. Pituitary hormone testing revealed hyperprolactinemia for which the patient did not receive treatment as he was asymptomatic. During a subsequent hospital admission for seizures, the patient was diagnosed with transient central diabetes insipidus for which he required treatment with a desmopressin infusion.

Female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women. The onset may be at any age following puberty and the frequency increases with age. Clinically, it shows a diffuse hair thinning over the central scalp, while the frontal hairline is usually retained. FAGA can have a significant psychological impact, leading to anxiety and depression. For this reason, early diagnosis is very important to stop the progression of the disease. The sex hormonal milieu is the main pathogenetic mechanism studied in FAGA. The role of androgens is not clearly defined and only one-third of women with FAGA show abnormal androgen levels. Endocrinological diseases with hyperandrogenism associated with FAGA comprise polycystic ovarian syndrome (PCOS), hyperprolactinemia, adrenal hyperplasia and, rarely, ovarian and adrenal tumours. Usually the diagnosis of FAGA is made clinically. A complete clinical examination and a blood examination can reveal other signs of hyperandrogenism. Trichoscopy shows the typical hair miniaturization. A scalp biopsy can be useful when the clinical evaluation does not provide a definitive diagnosis or when cicatricial alopecias with hair loss in the distribution of FAGA or alopecia areata are suspected. FAGA is a slowly progressive disease. The goal of therapy is to stop the progression and to induce a cosmetically acceptable hair regrowth. The most important drugs are topical minoxidil and oral anti-androgens. The purpose of this review is to provide an update on FAGA and to create a guideline on diagnosis and management of this frequent hair disease, not always easily recognizable from cicatricial alopecias with a similar distribution.
