A small hard lump on the vulva, if it is accompanied by redness, swelling, heat and pain, is mostly considered to be caused by inflammation, the most common being folliculitis. It is recommended not to pick and scratch to avoid local breakage leading to aggravation of infection, early specialist consultation and treatment with antibiotics under the guidance of a physician. If the small hard lump is not painful and itchy, it is mostly considered to be a cyst. If it is under the skin of vulva, it is common to find sebaceous cysts or lipomas. If it is between the labia majora and labia minora, it is common to see a vestibular gland cyst, which should be treated with topical medication or surgery. If vaginitis is present, repeated irritation of the vulvar skin due to increased secretions may also result in hard lumps, which require active treatment of vaginitis.
