Differential Diagnosis for Breast Lump with Tenderness
The following differential diagnosis is based on the provided mammography results and clinical presentation.
- Single most likely diagnosis
- Gynecomastia: This is the most likely diagnosis given the mammography findings of fibroglandular densities in the subareolar regions bilaterally, with the right side being significantly greater than the left, consistent with gynecomastia. The BI-RADS 2 assessment also supports a benign finding.
- Other Likely diagnoses
- Fibrocystic changes: The presence of scattered areas of fibroglandular density could also be indicative of fibrocystic changes, a common benign condition in the breast.
- Lipoma: A benign tumor made of fat tissue, which could present as a lump and may be tender.
- Cyst: A fluid-filled sac that can develop in the breast, potentially causing a lump and tenderness.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed)
- Breast cancer: Although the mammography results suggest a benign finding, it is essential to consider breast cancer as a potential diagnosis, especially if the patient has a family history or other risk factors.
- Phyllodes tumor: A rare type of breast tumor that can be benign, borderline, or malignant, and may present as a lump.
- Inflammatory breast cancer: A rare and aggressive form of breast cancer that can cause tenderness, swelling, and skin changes.
- Rare diagnoses
- Breast lymphoma: A rare type of cancer that can affect the breast tissue.
- Pseudolymphoma: A rare, benign condition that can mimic lymphoma.
- Hamartoma: A rare, benign tumor that can develop in the breast.
