'post inflammatory depigmentation'

Local freezing of tissue (-20°C to -196°C) is carried out with cryogens (freezing substances) such as Carbon Dioxide Snow and Liquid Nitrogen to treat warts, molluscum contagiosum severe acne and its scars, keloids, leukoplakia, actinic keratosis and to destroy early lesions of skin malignancies.

These are extra tissue growths which are commonly seen after traumatic/ surgical wounding or may follow ear-piercing / idiopathic (keliod only). They are painful, itchy & may get secondarily infected at high recurrence rate. They not only cause cosmetic disfigurement but may also lead to contractures & limb immobility. Surgical modalities include combination techniques such as debulking of tissue with scalpel, Radiofrequency, Liquid Nitrogen Cryosurgery, Laser along with Intralesional injections & silicone pressure dressing / garment.
