What is Keratoacanthoma lips and oral mucosa -
Keratoacanthoma (keratoacanthoma) is a benign epidermal tumor. Important role in its development belongs to chemical carcinogens, UV radiation. Suggested a possible hereditary nature of the lesion.
Symptoms of Keratoacanthoma lips and oral mucosa:
Keratoacanthoma may be localized on the red border of the lips, very rarely on the tongue. The disease begins with the formation on the lip grayish-red, dense knot with a little funnel-shaped depression in the center. The tumor grows quickly, within a month of the nodule reaches 2 cm in diameter. In its centre there is a well marked groove, filled with easy-to-remove Horny masses. Keratoacanthoma almost painless, movable, not soldered to the underlying tissues.
For keratoacanthoma characteristic cyclical flow with periods of growth, stabilization and spontaneous involution.
There are two outcomes of keratoacanthoma. The most frequent is its spontaneous disappearance with formation of atrophic pigmented scars or she is transformed into a cancer. Spontaneous disappearance of keratoacanthoma observed within the period of 3 months, however, there are persistent persistent options.
Histologically, keratoacanthoma is a sharply limited, somewhat protruding above the surrounding tissues, as it were pushed epithelial tumor with crater-shaped cavity, lined by epithelium and filled with a Horny mass. The epithelium is in a state of acanthosis. Often seen epithelial outgrowths penetrate deeply into connective tissue stroma. They observed cellular polymorphism, sometimes the appearance of dyskeratosis. The connective-tissue stroma there is an inflammatory infiltrate of plasma and lymph cells.

- cutaneous horn-
- warty precancer-
- squamous cell cancer.
