- Lichenification - Grossly thickened, leathery, hyperpigmented skin with hyperkeratosis and deep, widely-spaced skin markings
- Macule - Flat circular area demarcated by colour from surrounding tissue
- Nodule - Solid raised discrete lesion les than 5mm in diameter and depth
- Onycholysis – Separation of the nail from the nailbed Papule - Solid raised discrete lesion 5 mm
- Pedunculated - Attached to its base by a stalk-like structure
- Plaque - Flat but elevated area, usually les than 5mm
- Pustule - Small pus-filled elevated area of the skin with discrete borders
- Ulceration- Loss of epidermis with partial-to-complete loss of dermis
- Seborrheic - Related to excessive secretion of sebum
- Sebum – Thick and greasy substance secreted by sebaceous glands that consists of fat and other cellular debris
- Sessile - Attached directly to the skin by a broad base; not pedunculated

Diagnosis of a skin lesion:
Most skin lesions are benign, but it is still important to have a proper examination and assessment by one of our doctors.
The accurate diagnosis of any skin lesion can be made by conducting a full physical exam and by taking a skin biopsy.
Treatment of skin lesions:
As there is such a wide variety of skin lesions, the treatment can be varied. Treatment can range from applying a topical cream, surgery or laser treatment.
