What the difference between lipoma and phyllodes?

"Apples and Oranges": A lipoma is a benign fatty tumor that is most commonly found just under the skin anywhere on the body. They may occasionally cause discomfort but are most often removed for cosmetic reasons. A phyllodes tumor is a type of breast tumor that resembles a fibroadenoma; though benign, it can be locally aggressive; therefore, it is best treated by wide excision w/clear margins.

Benign vs malignant?: A lipoma is a benign mass that is composed of fat tissue. Phyllodes is a rare tumor of the breast that can grow quite rapidly. The majority of phyllodes are benign, but a small percentage can be malignant. (cancerous).

Big difference: A lipoma is a benign fatty tumor that typically requires no treatment. They are very common and occur all over the body. A phyllodes tumor of the breast is often benign, but can be malignant (cancer) and can recur after removal. These require treatment (excision with negative margins) and sometimes radiation.
