Abstract

Gigantomastia is a rare condition characterized by excessive hypertrophy of the connective tissue of the breast, which can cause physical and emotional distress. Surgical intervention is crucial for improving patients’ quality of life; however, it is challenging to balance minimizing the risk of recurrence and maximizing favorable aesthetic outcomes. This study documents the successful management of three rare cases of bilateral gigantomastia resulting from benign tumors. These cases included rapidly growing bilateral diffuse tumorous pseudoangiomatous stromal hyperplasia (PASH) and bilateral juvenile giant fibroadenoma, with no long-term recurrence observed. We discuss the diagnostic challenges and management considerations for gigantomastia, with a focus on reviewing PASH and its differential diagnosis. The findings offer valuable insights into the successful management of diverse gigantomastia cases caused by benign tumors, potentially aiding clinicians in making more informed decisions regarding optimal patient care.
