Identify a ganglion cyst. These are the most common types of lumps found on the hand and wrist. They are not cancerous and often harmless. Filled with fluid, they can quickly appear, disappear or change in size. They do not require treatment unless they interfere with function or are unacceptable in appearance.
Consider getting a second opinion if you are not satisfied with your physician’s diagnosis and treatment. Although most epidermoid and pilar cysts do not require treatment from a physician, if you do seek medical advice and are not satisfied with the results seek a second opinion. Most sebaceous and epidermoid cysts are straightforward, but there are other conditions that may mimic these cysts.
In a case study written in the Royal College of Surgeons of England, the authors presented two cases in which melanoma and a deep oral cavity were originally mistaken for a sebaceous cyst.
