[pT1c Breast Cancer Presenting with Skin Rupture without Skin Invasion-A Case Report]

Area of Science:

• Oncology
• Surgical Pathology

Background:

• Breast bleeding is an uncommon presentation of breast cancer.
• Malignant breast masses may not always present with visible skin changes.

Purpose of the Study:

• To report a rare case of breast cancer presenting solely with bleeding.
• To emphasize the importance of clinical suspicion in diagnosing breast cancer.

Main Methods:

• A case report of a female patient in her 70s with a history of untreated breast mass.
• Diagnostic procedures included clinical examination, needle biopsy, and subsequent lumpectomy with sentinel lymph node biopsy.
• Pathological analysis confirmed invasive ductal carcinoma.

Main Results:

• The patient presented with recurrent breast bleeding, initially misdiagnosed by needle biopsy.
• Pathological examination revealed invasive ductal carcinoma (pT1c, pN0 (sn), M0, pStageⅠ) without skin invasion.
• Post-surgical treatment with tamoxifen and radiation therapy resulted in no recurrence.

Conclusions:

• Breast bleeding can be the primary sign of breast cancer, even without skin invasion.
• Clinical diagnosis and thorough pathological evaluation are essential for accurate breast cancer staging and treatment planning.
• Adjuvant therapy plays a vital role in preventing recurrence of early-stage breast cancer.
