Fat necrosis of breast
Clinical Classification Guidelines
Inclusion Terms
- Fat necrosis (segmental) of breast
Code First
- breast necrosis due to breast graft (T85.898)
Medical Intelligence & Overview
Fat necrosis of the breast is a benign (non-cancerous) condition that occurs when fatty tissue in the breast is damaged and begins to die. This process often results in the formation of a lump or scar tissue within the breast. Although it can sometimes mimic breast cancer in its appearance and symptoms, fat necrosis is harmless and typically does not require extensive treatment. Recognizing the signs and understanding what causes this condition can help alleviate concerns and inform proper medical evaluation.
Causes & Symptoms
Clinical Causes: Trauma or injury to the breast, such as a blow or a fall Surgical procedures involving the breast, like biopsies, lumpectomies, or reduction surgeries Radiation therapy targeted at the breast Injections or other localized trauma Rapid weight loss or significant changes in breast size
Key Symptoms: A firm, painless lump in the breast Skin changes over the affected area, such as redness or dimpling Color changes in the skin, including bluish or bruised appearance Tenderness or sensitivity in the affected region Sometimes, no symptoms are present, and the condition is found during routine examinations or imaging
Diagnostic & Treatment
Diagnosis Path: Detection of fat necrosis usually involves a combination of clinical examinations and imaging tests. A healthcare provider may perform a physical exam to assess the lump, its location, and any associated skin changes. Imaging techniques such as mammography or ultrasound are commonly used to evaluate the area. In some cases, a biopsy may be necessary to differentiate fat necrosis from other breast conditions, including malignancies. The biopsy will examine tissue samples microscopically, confirming the presence of dead fatty tissue and scar formation characteristic of fat necrosis.
Treatment Protocols: Most cases of fat necrosis do not require aggressive treatment. Management often involves monitoring the lump for changes over time. If the lump is causing discomfort or cosmetic concerns, options may include:
