Differential Diagnosis for Active Bleeding Breast Mass
- Single most likely diagnosis
- Breast cancer with hemorrhagic necrosis: This is a common cause of a bleeding breast mass, especially in older women or those with a history of breast cancer. The tumor can outgrow its blood supply, leading to necrosis and bleeding.
- Other Likely diagnoses
- Fibroadenoma with infarction: Fibroadenomas are common benign breast tumors that can undergo infarction, leading to bleeding and necrosis, especially during pregnancy or breastfeeding.
- Breast cyst: Simple breast cysts can rupture and cause bleeding, although this is less common.
- Hematoma: Trauma to the breast can cause a hematoma, which can present as a bleeding breast mass.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Angiosarcoma: A rare and aggressive malignant tumor that can cause bleeding due to its vascular nature. It is essential to consider this diagnosis to ensure prompt treatment.
- Pseudoangiomatous stromal hyperplasia (PASH) with hemorrhage: PASH is a rare benign condition that can mimic angiosarcoma and cause bleeding.
- Metastasis to the breast: Although rare, metastatic disease to the breast from other primary sites (e.g., melanoma, lung, or renal cell carcinoma) can cause a bleeding breast mass.
- Rare diagnoses
- Hemangioma: A benign vascular tumor that can cause bleeding, although this is rare in the breast.
- Lymphangioma: A rare benign tumor of the lymphatic vessels that can cause bleeding.
- Breast lymphoma: A rare malignant condition that can cause a bleeding breast mass.
