Epithelioma - causes, symptoms, diagnosis and treatment

Epithelioma - Swelling of the skin and mucous membranes, which develops from the cells of the surface layer - the epidermis. Epithelioma different variety of clinical options from small nodules to the considerable size of tumors, plaques and ulcers. There may be benign or malignant nature. Their diagnosis includes dermatoscopy, bakposev discharge, ultrasound education, histological examination of removed tissue or biopsy material. Treatment is mainly surgical, with the malignant nature of the tumor - radiation, chemotherapy, photodynamic, using both general and local methods of influence.

    Dermatology, most authors refer to the following epithelioma skin neoplasms: basal (basal cell epithelioma) squamous cell carcinoma (spinotsellyulyarnuyu epithelium) and trihoepiteliomu (adenoidnuju cystic epithelium). Attempts by some researchers to identify the epithelium with skin cancer seems inappropriate because the benign skin tumors found among epithelial rarely undergo malignant transformation.

    Most epithelioma occurs in patients mature and advanced age. The most common is basal cell carcinoma epithelioma, which accounts for 60-70% of all cases.

    chronic solar dermatitis, radiation dermatitis, eczema, professional, traumatic dermatitis, on the site of the scar after suffering burns.

    malignancy since it has invasive growth, it grows not only the dermis and subcutaneous tissue, but also to be muscle tissue and bone structure. However, it does not tend to metastasize.

    Rare forms of basal cell carcinoma include samorubtsuyuschayasya epithelioma and calcified epithelioma Malerba. Samorubtsuyuschayasya epithelioma is characterized by the collapse of a typical bazaliomnogo nodule with formation of the ulcer. In the future, there is a slow increase in the size of the ulcer, accompanied by scarring its individual parts. In some cases, it goes into squamous cell skin cancer.

    Calcified epithelioma Malerba - a benign tumor, which appears as a child of the sebaceous gland cells. Manifested in the formation of the face, neck, scalp and shoulder girdle of the unit is very dense, rolling slowly growing nodule size from 0.5 to 5 cm.

    Spinotsellyulyarnaya epithelioma It develops from cells spinous layer of the epidermis and has a malignant course with metastasis. Favourite localization - perianal skin and genitalia, red border of the lower lip. Can flow from the node formation, plaque or ulcers. Characterized by a rapid increase in peripheral and deep tissues.

    Adenoid cystic epithelioma It is more common in women after puberty. In most cases, it is presented by multiple painless tumor size to a large pea. Colour formation can be bluish or yellowish. Occasionally found a whitish color, due to which epithelioma elements may resemble acne. In some cases, there is the appearance of a single tumor, reaching the size of a hazelnut. Typical localization of elements - the ears and face, rarely affected scalp, even rarer - the shoulder girdle, abdomen and extremities. Typically a benign and slow flow. Only in a few cases there is a transformation in the basalts.

    dermatologist trying to connect all the possible methods of research: dermatoscopy, skin ultrasound education bakposev discharge discharge ulcers. However, a definitive diagnosis to determine the clinical form of the disease, its benign or malignant, allows you to install only the histological study obtained by removing epithelioma or biopsy material of skin.

    The differential diagnosis is carried out with lichen planus, psoriasis, Bowen's disease, systemic lupus erythematosus, scleroderma, seborrheic keratosis, a disease Keir et al. Adenoid cystic epithelioma requires differentiation from hidradenitis sup-, xanthelasma, squamous cell skin cancer, common warts.

    surgical excision of education. When multiple small tumors may use cryoablation, laser removal, curettage and electrocoagulation. With deep germination and presence of metastasis surgery may wear a palliative. The malignant nature of the tumor is an indication for surgical treatment of the combination with rentgenoradioterapiey, photodynamic therapy, or general outdoor chemotherapy.

    In benign nature of the disease, timely and complete removal of the tumor prognosis. Basal cell epithelioma spinotsellyulyarnaya and prone to frequent postoperative recurrence for early detection that require constant monitoring Dermatooncology. The most unfavorable prognostic is spinotsellyulyarnaya plan form of the disease, especially in the development of tumor metastasis.
