TL;DR

A rare and aggressive breast cancer case highlights the difficulty in treating primary small cell carcinoma of the breast and the need for standardized protocols.

Contribution

This paper presents a clinical case emphasizing the challenges in managing primary small cell carcinoma of the breast and the need for standardized treatment.

Findings

The patient received neoadjuvant chemotherapy, surgery, and radiation but later developed metastatic disease.

Despite additional therapies, the patient continued to have widespread metastatic disease.

The case highlights the urgent need for standardized treatment protocols for PSCCB.

Abstract

Primary small cell carcinoma of the breast (PSCCB) is a rare but aggressive disease with multiple treatment options available, including surgery, chemotherapy, and radiation therapy. We report a case of a 51-year-old female patient who presented with a palpable left breast mass. An ultrasound-guided core needle biopsy of the affected area revealed triple-negative small cell carcinoma of the left breast. The patient underwent neoadjuvant chemotherapy, breast-conserving surgery with negative margins, and post-operative radiation therapy. One year later, the patient developed pathologic evidence of metastatic disease. Despite receiving three additional chemotherapeutic regimens and site-specific radiation treatments, the patient continued to have widespread metastatic disease. This case underscores the challenges of diagnosing and treating PSCCB and the urgent need for creating a standardized treatment protocol to improve patient outcomes.
