Gynecomastia in a Patient Taking Meloxicam-A Case Report.

Abstract

Gynecomastia is benign enlargement of glandular tissue in the male breast. It occurs due to an imbalance of estrogen and testosterone. It may be unilateral or bilateral. Physiologic gynecomastia commonly occurs in infants and during puberty and is self-limited. Gynecomastia may affect up to 50% of adult men over age 50 years old and can be related to underlying medical illness or caused by certain medications. Known causative agents include anti-androgenic and estrogenic drugs. Probable agents include alcohol and anti-ulcer, psychoactive, and antiretroviral medications. Non-steroidal anti-inflammatory drugs (NSAIDs) are not commonly associated with the development of gynecomastia. This case presents an instance in which the NSAID, meloxicam, was the only identified variable in a patient who developed unilateral gynecomastia. His breast tenderness and abnormal exam resolved spontaneously within 4 weeks of cessation of meloxicam therapy.
