Patient case (clinical description): A 19-year-old girl comes to the clinic due to a left wrist mass.  She noticed swelling on the top of her wrist about 4 months ago and came to the clinic due to cosmetic concerns.  Examination shows a nontender, rounded mass on the dorsal wrist that transilluminates with a penlight. Vital signs are normal. The patient needs to type on her computer almost all day. She is left-handed. She does not smoke or use illicit drugs. She is in sexual relationship with two male partners and uses condoms.

Patient's own account: I'm a 19-year-old girl and I went to see my doctor because of a mass on my left wrist. I noticed a swelling on top of my wrist, like 4 months ago, and I went the first time to the doctor because it was pretty ugly! My wrist was not tender, and the mass was round and let the light go through when the doctor used a penlight. My blood pressure, breathing and temperature were normal. I'm left-handed and I need to be on my PC all day. I don't smoke or do drugs. I'm sexually active and I have 2 male partners but they all use condoms.
