Final answer:
The correct term for pathologic enlargement of the male breast is gynecomastia, a condition often due to hormonal imbalances or gland malfunctions.
Step-by-step explanation:
The pathologic enlargement of the male breast is called gynecomastia. This condition can result from the excessive production of prolactin leading to symptoms like amenorrhea, galactorrhea, and breast enlargement. Gynecomastia can occur due to normal hormonal fluctuations in the body, the use of hormonal birth control, certain diseases, and malfunctions of glands that release hormones. It is essential to differentiate gynecomastia from other conditions such as epidermal cysts, mastitis, or breast cancer, which may also affect the breast tissue. A biopsy may be recommended in cases where there is a suspicion of cancer to rule out malignancy. Understanding of the anatomy of the breast, including lactiferous ducts, alveoli, and lobules, is crucial in diagnosing and treating gynecomastia.
