Planocellular carcinoma cutaneum

Description:

Planocellular cancer (spinotsellyulyarny cancer, planocellular epithelioma) proceeds from cells of an acanthceous layer of epidermis. Planocellular cancer arises on skin much less than a bazalioma.

Symptoms of the Planocellular carcinoma cutaneum:

Generally planocellular cancer is localized on a red border of an under lip, in perianal area, on external genitals.

The planocellular carcinoma cutaneum differs in the clinical current from a bazalioma. At planocellular cancer patients show complaints to a tumor or ulcer of integuments which quickly increase in sizes. At extensive damage of skin and glubzhelezhashchy fabrics and accession of inflammatory process owing to infection there are pains.

Development of planocellular cancer goes on the way of formation of an ulcer, a node, a plaque. The ulcer form of a planocellular carcinoma cutaneum is characterized by sharply raised, dense edges surrounding it from all directions in the form of the roller. Edges of an ulcer fall abruptly down, giving it a type of a crater. Ulcer bottom uneven. From a tumor plentiful serous and bloody exudate which dries up in the form of crusts is emitted. From a new growth the unpleasant smell proceeds. The cancer ulcer progressively increases in sizes, both in width, and in depth.

The cancer node reminds by outward a cauliflower or a mushroom on the wide basis, a surface its krupnobugristy. Color of a tumor brown or bright red. Consistence, as node, and its basis dense. On a surface of a node there can be erosion and ulcers. Growth of this form of a planocellular carcinoma cutaneum bystry.

The cancer tumor in the form of a plaque, as a rule, a dense melkobugristy surface of consistences, red color, bleeds, quickly extends on a surface, and later and in the subject fabrics.

Cancer on a hem is characterized by its consolidation, emergence on a surface of ulcerations and cracks. Hilly growths are possible.

In zones of regional innidiation (in inguinal area, an axillary hollow, on a neck) dense, painless, mobile lymph nodes can appear. Later they lose mobility, become painful, are accustomed to drinking with skin and break up with formation of ulcerated infiltrates.

Reasons of the Planocellular carcinoma cutaneum:

Planocellular cancer can arise against the background of a solar or senile keratosis, develop in cicatricial fabric on site of a burn, injuries, a chronic inflammation, x-ray dermatitis, a pigmental xeroderma, etc.

In recent years the importance of certain viruses of papilloma of the person in development of planocellular cancer is established. Process of carcinogenesis happens at synergy action of a virus to physical and chemical carcinogens and is caused by genetic adjustable immune mechanisms.

Treatment of the Planocellular carcinoma cutaneum:

Treatment of a planocellular carcinoma cutaneum consists tumors within healthy fabrics at a distance (surgical excision in combination with X-ray radiotheraphy, a cryolysis, laser therapy, the general and outside chemotherapy, photodynamic therapy, etc.).

The choice of a method of treatment of a planocellular carcinoma cutaneum depends on a stage, localization, prevalence of process, existence of metastasises, age and the general condition of the patient.

Electrothermic coagulation, curettage, cryolysis are more often used at small and multiple tumors, however the last is not applied at a tumor arrangement on a pilar part of the head.

At himiokhirurgichesky treatment by a method Mocha is noted the high level of an izlechennost (to 99%), the maximum of normal skin around the center remains. It is reasonable to use a method at tumors with badly defined borders. The roentgenotherapy is carried out more often at localization of a tumor in a nose, a century, lips, and also to the elderly persons incapable to transfer surgical treatment.

At a recurrence of a planocellular carcinoma cutaneum himiokhirurgichesky treatment, a roentgenotherapy, aromatic retinoids inside are shown (неотигазон, этретинат, etc.).

The main task of the dermatologist – early diagnosis of a precancerous dermatosis and at identification of its malignancy (by a cytologic or histologic research) the direction of the patient to the oncologist who will resolve an issue of the choice of tactics of treatment. Success of treatment depends on early diagnosis, removal of precancerous elements and protection of the patient against further influence of carcinogens.
