[Pubertal prolactin adenoma. Eight cases (author's transl)].

Among 70 operated patients with a histologically verified prolactin secreting adenoma, 8 cases (7 girls, 1 boy) presented the onset of clinical signs before, during or immediately after puberty. Two different clinical syndromes were detected. In the younger patient group (4 cases), the first clinical signs at the onset of puberty were arrest of both growth and pubertal development. In the four remaining causes where in puberty had been achieved, primary-secondary amenorrhea and galactorrhea were observed. Sellar tomograms revealed the presence of invasive adenoma in 3 patients, and circumscribed (enclosed) adenoma in 5 cases. In 7 cases, surgical management was by the transsphénoïdal approach, while one patient underwent subfrontal surgery. Post-operative results were a function of tumour size. In the seven patients having undergone transsphenoïdal surgery, 4 patients displayed a return to normal prolactin function. In the remaining patients, post-operative management was conducted with bromocriptin and without radiotherapy.
