Nodulocystic acne
Nodulocystic acne is a severe form of acne affecting the face, chest and back. It is characterised by multiple inflamed and uninflamed nodules and frequently, scars.
It is more common in males. The name implies there are nodules (firm lumps) and cysts (fluid-filled cavities lined by epithelium).
Keratoacanthoma is a skin lesion that erupts in sun damaged skin, rather like a little volcano. It grows for a few months, then may shrink and resolve by itself.
Keratoacanthoma is considered to be a variant of the keratinocytic or non-melanoma skin cancer, squamous cell carcinoma (SCC).
As it cannot be clinically reliably distinguished from more serious forms of skin cancer, keratoacanthomas are usually treated surgically.
