Summary
This case report details synchronous bilateral solid papillary carcinomas (SPCs) of the breast, highlighting their scattered nature and association with other invasive breast cancer types. Preoperative diagnosis of such complex cases remains challenging.
Area of Science:
- Oncology
- Breast Cancer Research
- Pathology
Background:
- Synchronous bilateral breast cancer is rare.
- Solid papillary carcinoma (SPC) is an uncommon subtype of breast cancer.
- Limited data exists on the presentation and management of synchronous bilateral SPCs.
Purpose of the Study:
- To report a rare case of synchronous bilateral solid papillary carcinoma (SPC) of the breast.
- To discuss the diagnostic challenges and varied pathological findings in such cases.
- To contribute to the limited existing literature on bilateral SPCs.
Main Methods:
- Case presentation of a 73-year-old female with bilateral breast masses.
- Diagnostic workup including mammography, ultrasound, fine-needle aspiration biopsy, and MRI.
- Surgical intervention: bilateral partial mastectomy, sentinel lymph node biopsy, and subsequent total mastectomy.
- Pathological examination of resected tissues.
Main Results:
- Diagnosis of synchronous bilateral breast cancer with multiple subtypes including invasive ductal carcinoma NOS (right breast), mucinous carcinoma (left breast), and bilateral SPCs.
- Positive surgical margins for SPCs necessitating further mastectomy.
- Detection of lymph node metastasis in the right axilla.
- Observed diffuse small nodules surrounding the primary tumors bilaterally.
Conclusions:
- Synchronous bilateral SPCs can present with diverse invasive carcinoma types.
- SPCs may exhibit a widely scattered pattern, complicating diagnosis and treatment.
- Accurate preoperative evaluation of synchronous bilateral SPCs with varied presentations is difficult.
