IGM Registry

The purpose of the Idiopathic Granulomatous Mastitis (IGM) Registry is to collect data on a large cohort of patients across multiple institutions to identify the most efficacious ways to treat this condition. The IGM Registry uses a short data-entry form housed in the Society’s HIPAA-compliant Mastery of Breast Surgery® Program, a member benefit.

The deadline to enter new patients was August 1, 2023. We ask participating surgeons to complete their follow-up reporting as soon as possible using the Granulomatous Mastitis Registry Incomplete Report on their My Reports page. If you have questions, please contact mastery@breastsurgeons.org.

Timeframe and Expectations

Participants will enter data on medical and surgical management, comprised initial data and 1-, 3-, 6-, and 12-month follow-up data. Results will be released to the membership after the completion of data collection and analysis.

Frequently Asked Questions

    Idiopathic granulomatous mastitis (IGM) is an uncommon inflammatory condition that requires specialized care. Etiology is unclear and medical and surgical management is complicated. There is a paucity of high-quality literature on its treatment. These patients often get discussed on the ASBRS Forums with mixed recommendations. It is a problem the membership has to treat without consensus on the best treatments. The purpose of this registry trial to be able to collect data on a large cohort of patients across multiple institutions to identify the most efficacious ways to treat this condition.

    Study aims:

    • To collect prospective multi-institutional data on the most common diagnosis, medical and surgical treatments for IGM

    • To identify which patients will have a high chance of success with medical management and which ones will likely need surgery

    • To compare the best initial medical management strategies for IGM with shortest time to resolution
