The incidence of these tumours varies with age and sex, occurring most frequently in females between 20 and 40-years-old. The clinical symptoms of prolactinomas are menstrual dysfunction and galactorrhea in women and loss of libido and potency in men. Differential diagnosis o...

Our patient is a 32-year-old female with a history of a macroprolactinoma for approximately 17 years who presented to our hospital with a his...
متن کاملEndometrioid Endometrial Carcinoma Indirectly Caused by Pituitary Prolactinoma: A Case Report
We present the case of a 44-year-old nulliparous woman who experienced irregular menstrual cycles for about 10 years and developed both pituitary prolactinoma and endometrioid endometrial carcinoma. In premenopausal women, hyperprolactinemia causes hypogonadism by inhibiting secretion of gonadotropin-releasing hormone and thus suppressing luteinizing hormone levels, which can cause menstrual di...
متن کاملWhat causes a prolactinoma to be aggressive or to become a pituitary carcinoma?
INTRODUCTION Malignant prolactinoma is an exceedingly rare endocrine tumor and cannot be diagnosed on histological grounds alone. Similarly to other neuroendocrine tumors such as pheochromocytoma, the mitoses index, Ki-67, p53, and others are utilized in helping understand whether a tumor is benign or malignant or to better predict tumor behavior. We here present the unusual case of an unfortun...
متن کاملA Histopathological Study of Multi-hormone Producing Proliferative Lesions in Estrogen-induced Rat Pituitary Prolactinoma
Rats with estrogen-induced prolactin-producing pituitary adenoma (E2-PRLoma) have been employed as an animal model of human PRL-producing pituitary adenoma in a large number of studies. Presently, we found that long-term administration of estrogen to SD rats resulted in the development of E2-PRLomas, some of which included multi-hormone producing nodules. We herein report results of histopathol...
