PROLACTINOMA - PATHOLOGY ANIMATED LECTURE

Video Description

Prolactinoma

An adenoma of the anterior lobe of the pituitary gland that produces prolactin. It is the most common type of pituitary gland adenomas and it is associated with hyperprolactinemia.

In premenopausal women, oligomenorrhea, amenorrhea, infertility and, less often, spontaneous or expressive galactorrhea may be seen. Vaginal dryness and dyspareunia may also be features. Signs include decreased bone mineral density.

In postmenopausal women, presenting symptoms are related to the space-occupying effects of the tumor (headaches, visual disturbances like bitemporal hemianopsia, etc) because they are already hypoestrogenic.

In men, symptoms may include impotence, infertility, decreased libido and, rarely, gynecomastia.
