Radiology · Breast imaging: phyllodes tumour

Sample item

A 40-year-old woman has a rapidly enlarging, smooth breast lump. Ultrasound shows a large, lobulated, well-circumscribed solid mass with clefts or cystic spaces. Core biopsy shows a leaf-like pattern. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Phyllodes tumour

Phyllodes tumours are fibroepithelial lesions that grow quickly, can be benign, borderline or malignant, and mimic a fibroadenoma on imaging, but are larger with cystic clefts. Wide local excision is the treatment.

Option by option

  • A. Phyllodes tumour (correct)

    Correct. A rapidly growing large lobulated mass with a leaf-like architecture is a phyllodes tumour.

  • B. Lipoma

    A lipoma is a soft echogenic fatty mass.

  • C. Simple cyst

    A simple cyst is anechoic with thin walls.

  • D. Invasive lobular carcinoma

    Invasive lobular carcinoma is usually an ill-defined spiculated lesion.
