Botryoid-type embryonal rhabdomyosarcoma is a cancer that starts from very early cells that can grow into skeletal muscle. “Botryoid” means “grape-like.” These tumors often...
Botryoid rhabdomyosarcoma (also called sarcoma botryoides) is a cancer that grows from very early cells that can become skeletal muscle. It is a special...
An ovarian low malignant potential tumor—also called a borderline ovarian tumor—is a growth that starts from the surface lining (epithelium) of the ovary. It...
Low malignant potential (LMP) ovarian tumor (also called a borderline ovarian tumor) is a growth that looks abnormal under the microscope but does not...
A Epithelial tumor of the ovary of borderline malignancy (also called a “tumor of low malignant potential”) is an epithelial ovarian growth that shows...
A borderline ovarian surface epithelial-stromal tumour is a growth that starts in the surface lining cells of the ovary. The cells multiply more than...
Primary osteosarcoma is a cancer that starts in the bone itself. The tumor cells are abnormal bone-forming cells. They make a disorganized, immature bone...
Osteogenic sarcoma, also called osteosarcoma, is a cancer that starts in bone-forming cells. These cancer cells make immature bone (“osteoid”) inside the tumor. It...
Trichodiscomas are small, harmless bumps that grow from hair-follicle tissue in the skin. Doctors call them hamartomas, which means an overgrowth of normal skin...
Fibrofolliculomas are small, smooth, skin-colored bumps that grow around a hair follicle. They are benign (not cancer). Each bump is usually 2–4 mm across,...
