For treatment there is but little encouragement, least of all for operative intervention. Growths nearly always recur after removal.
In the cheek cysts of Stenson’s duct and dermoid tumors and cysts have often been observed near the parotid region. The so-called “fatty ball of Bichat” is occasionally the site of an angioma, which may press upon Stenson’s duct and be accompanied by calculus in the parotid gland, the superficial veins being much dilated. (Souchon.)
Fatty tumors, as well as sarcoma in this same tissue, are prominent. The most frequent tumors of the face are the epitheliomas of the lip, nearly always of the lower lip, occurring oftener in men than in women. A growth of this character at this site is regarded as an expression of the result of irritation, which may be produced by a carious tooth or by constant friction of a pipe-stem, or from many other causes. It frequently develops at the site of an old chronic fissure. These growths spread from small beginnings, and if, when small, they were extirpated there would be fewer cases of cancer of the lip spreading to and involving the face and neck. Every ulcer of the lip whose base becomes indurated, and from which the syphilitic element can be excluded, should be excised, the ensuing defect being repaired by a plastic operation. (See above.)
