Area of Science:

Oncology
Pathology

Background:

Primary mammary sarcomas are rare, heterogeneous malignant neoplasms.
Undifferentiated pleomorphic sarcoma (UPS) is a rare subtype characterized by cellular atypism and pleomorphism.

Observation:

A 62-year-old woman presented with a rapidly growing, 18-cm left breast tumor.
The tumor was painless with spontaneous bleeding, an atypical clinical presentation for UPS.
No axillary lymphadenopathy was detected on physical examination or mammography.

Findings:

Histopathological and immunohistochemical studies were crucial for diagnosing UPS.
Diagnosis is challenging due to the lack of specific markers and requires exclusion of other soft tissue sarcomas.
The large size and unique clinical presentation distinguished this case.

Implications:

This case underscores the importance of comprehensive histopathological evaluation for rare breast tumors.
Understanding atypical presentations of UPS is vital for timely diagnosis and management.
Further research into specific markers for UPS could improve diagnostic accuracy.
