A phyllodes tumor, also known as a cystosarcoma phyllodes, is a rare type of breast tumor that develops in the connective tissue of the breast. It is named after its leaf-like appearance under a microscope, resembling the Greek word "phyllon" meaning leaf. Phyllodes tumors are typically found in women between the ages of 35 and 55, although they can occur at any age.
These tumors are classified as fibroepithelial tumors, as they contain both stromal (connective tissue) and epithelial (glandular) components. Phyllodes tumors are usually benign (non-cancerous), but in rare cases, they can be malignant (cancerous). Malignant phyllodes tumors have the potential to spread to other parts of the body.
Phyllodes tumors are often discovered as a painless lump in the breast during a routine breast examination or mammogram. They can grow rapidly, causing changes in breast size and shape. Other symptoms may include breast pain, tenderness, or a palpable mass.
When diagnosing a phyllodes tumor, a healthcare provider may perform a physical examination, imaging tests (such as mammography or ultrasound), and a biopsy to determine whether the tumor is benign or malignant. Treatment options for phyllodes tumors typically involve surgical removal of the tumor, with the extent of surgery depending on the size and characteristics of the tumor.

It is important to note that while phyllodes tumors are rare, they should be evaluated and treated by a healthcare professional to ensure appropriate management and follow-up care.
