Capsulectomy Can Successfully Treat Chronic Encapsulated Breast Seroma: A Case Report

Chronic encapsulated seroma following breast cancer surgery is a rare entity, and management is challenging. We present clinical and pathologic findings in a patient with previous node-negative breast cancer and an extensive history of chronic bilateral seromas, successfully treated with capsulectomy. This is the first report of fibrous encapsulated breast seroma with bilateral presentation and late onset, following mastectomy with no prior axillary dissection. When managing breast seroma refractory to conventional treatment, the diagnosis of encapsulated seroma should be considered, followed by prompt capsulectomy.
