Galactocele

Introduction

• Description: Galactocele is the cystic dilation of a duct or ducts, with inspissated milk and desquamated epithelial cells that may become infected, resulting in acute mastitis or an abscess.

• Prevalence: Common in asymptomatic form.

• Predominant Age: Reproductive (lactating) age.

• Genetics: No genetic pattern.

Etiology and Pathogenesis

• Causes: Ductal obstruction and inflammation during or soon after lactation may lead to cystic dilation of a duct or ducts and the subsequent development of a galactocele. Galactocele is generally associated with breastfeeding, but it may on rare occasions be associated with galactorrhea or oral contraceptive use.

• Risk Factors: Breastfeeding and abrupt weaning, mastitis, galactorrhea. There are data that suggest a weak association with periareolar incisions, subglandular breast implants, prior hormonal contraceptive use, and increased gravidity.

Signs and Symptoms

• Painless mass palpable in the central portion of the breast
