Mom has weird mole with white head in it?? the tiny white piece that is poking out from the mole is hard, not soft like puss. what is this? scary.

Cyst: this is likely an unroofed sebaceous cyst. Take your mother to see her doctor or a Dermatologist to look at it. If I am correct it can easily be treated.

See a Dermatologist: When you have something weird and abnormal growing on your skin, it is important to see a dermatologist to get a correct diagnosis and treatment to make sure it is not something dangerous like a skin cancer.

MD evaluation: Moles can range from benign lesions to malignancies. The description may be a benign sebaceous cyst or may represent an early malignancy like KeratoAcanthoma. However, because a lesion has benign cell types, does not mean that it cannot cause serious problems. The best advice for your mother is to allow a knowledgeable dermatologist or Board Certified Plastic Surgeon to evaluate.
