Fibroadenoma of the Breast Occurring Synchronously in Twin Sisters- A Case Report

Abstract

<p>Fibroadenomas (FAs) are the most common benign tumors of the breast in young females. Most of the time, it presents as a well-circumscribed, painless, firm to hard, mobile, and slow-growing unilateral or bilateral breast lump. The median age of its presentation is 25 years with rare occurrence after menopause. The exact etiology of FA is still unclear. Unopposed estrogen in the growing breasts of young females is considered as a main factor in its pathogenesis. Family history and development of FA in identical twins are suggestive of genetic contribution to the pathogenesis of these tumors.</p>
 <p>This is a case report of young twin sisters who presented at a tertiary care hospital in Lahore with a complaint of a synchronously developed unilateral breast lump. Fine needle aspiration cytology was planned after taking a detailed history and clinical examination of both patients. Diagnosis of FA was confirmed radiologically and through cytological examination. To the best of the authors’ knowledge, this is the first case of its kind reported from Pakistan.</p>
