Moles refer to certain types of benign (non-cancerous) tumors composed of pigment-producing cells (melanocytes) that colonize the epidermis (upper layer of skin) and sometimes the dermis (lower layer of skin). While there exist many different types of moles, some of the commonly observed types include the following three:
- Junctional Nevus: a junctional nevus is a light to dark brown coloured, oval-shaped flat mole, and is the shallowest of the three types. A small junctional nevus (typically less than 3mm diameter on healthy facial skin) may be treated with laser yielding a positive cosmetic outcome. Larger sized lesions require surgical removal for the best cosmetic result.
- Intradermal Nevus (also known as the Dermal Nevus): an intradermal nevus is a light brown or skin coloured, oval-shaped raised mole, which sits deep inside the skin. Due to the depth of the mole, intradermal nevi are best treated using surgical methods, as a laser removal typically results in a higher chance of recurrence and scarring.
- Compound Nevus: a compound nevus typically has a brown coloured, oval-shaped raised center sitting on a flat oval-shaped brown spot. It is generally less dark than a junctional nevus and less raised than an intradermal nevus.
Certain skin cancers may appear with characteristics that closely resemble those of a mole, and, if suspected, require further biopsies and/or special removal techniques. Therefore, ready access to dermastocopy, as equipped by SKINLIFE CLINIC, is essential prior to removal so that the telltale signs of skin cancers that are not readily visible to the naked eye can be revealed and the appropriate measures taken.
