Could you please explain what an epithelioma of Malherb is?
It is otherwise known as pilomatrixoma. I understand that it is a benign tumour, but I'd like to know exactly what it is and what causes it.
Malherb is not a recognised term, but epitheliomas are extremely common.
They are derived from the skin and they often contain semi-solid material or liquid that is produced by the epithelium itself.
Epitheliomas may take the form of a cyst, particularly epidermoid cysts, which are little closed sacs lined by the most superficial layer of the skin.
The second most frequently occurring skin cyst is the trichilemmal (pilar) cyst, which most often form from scalp hair follicles and may be multiple.
Both are formed by the cystic enclosure of the epithelium within the dermis and may also be called sebaceous, infundibular or epidermal cysts.
Cysts can get infected, and although they are not cancerous or invasive things they are sometimes a very persistent nuisance.
