Case in brief
A 58-year-old male presented with a stable, non-painful left breast mass, initially misdiagnosed as a lipoma. Imaging revealed a suspicious BIRADS 4 mass, and intraoperative frozen section suggested malignancy. Definitive histopathology confirmed encapsulated papillary carcinoma (EPC) with positive hormone receptors and negative margins. The patient underwent successful surgical resection and had an uneventful recovery, with a low recurrence risk post-surgery.
What made this case unusual
The case highlights the diagnostic challenges of EPC, which can mimic benign lesions and is often misidentified, complicating preoperative imaging interpretations.
Diagnostic / clinical pearl
Clinicians should be aware that encapsulated papillary carcinoma, though rare, can present as a cystic mass in males and may be mistaken for benign conditions, necessitating careful evaluation.
Why it matters
Understanding the characteristics and management of EPC is crucial, as it has a favorable prognosis when diagnosed early and treated appropriately, aligning with current guidelines.
