What Is Epithelial Carcinoma?

Squamous cell carcinoma, referred to as squamous cell carcinoma, also known as epidermoid carcinoma. It is a malignant tumor that originates from the skin or mucosal spinal cells. The disease may be related to long-term sun exposure or exposure to tar substances and arsenic agents.

Overview of Epithelial Cancer

It often occurs on the basis of certain skin diseases, such as chronic ulcers, lupus vulgaris, chronic discoid lupus erythematosus, leukoplakia, burn scars, and dermatitis. Malignant degree is higher than basal cell carcinoma and prone to metastasis. The key lies in early diagnosis and early treatment.

Epithelial cancer signs

1. Common in the elderly over 50 years old, mostly occur at the junction of skin and mucous membranes.

2. At the beginning, it is a round and swollen dry verrucous nodule or a red hard plaque with a few scales on the surface, and then an ulcer occurs, which gradually expands, invades to the deep, and the edge valgus or forms a cauliflower-like mass. , Stench and conscious pain, lymph node metastasis and visceral metastasis can occur in the late stage.

Frequently occur in men over 50 years of age, and are common on the face, scalp, lower lip, back of the hand, forearm, genitals, etc.

Especially the junction of skin and mucous membrane is more likely to occur. It is dark red and hard wart-like nodules at the beginning, and the capillaries on the surface are dilated, with horny matter attached in the center, which is not easy to peel off. It can bleed after peeling. The skin lesions gradually expand, forming a hard red plaque with a few scales on the surface, a clear border, infiltration to the surroundings, and a harder touch. It rapidly expands to form ulcers. The ulcers invade the surroundings and deep, which can reach muscles and bones, and damage each other Adhesion forms a hard mass, which is not easy to move. The base of the ulcer is flesh red, with necrotic tissue, pus, odor, and bleeding. The edge of the ulcer is bulged and valgus with obvious inflammation and conscious pain. If it occurs at the junction of skin and mucous membrane, solid moisture and friction are more likely to bleed, develop faster, can form cauliflower-like, destructive, have obvious pain, easy to transfer, and poor prognosis.

The lesions are rough, desquamated, and ulcerated, and the adjacent lymph nodes and regional lymph nodes are enlarged and fixed. Most lung squamous cell carcinomas originate from a central main bronchi, lobar bronchi, or segmental bronchi.

Description of Oncology, Ophthalmology, and Disease Squamous cell carcinoma is also called skin-like carcinoma, which starts from the skin covered by squamous epithelium. The edge of the eyelid at the junction of the skin and conjunctiva is its multiple site. These cancers are more malignant than those with basal cell carcinoma. It has developed rapidly and caused great damage. It can destroy the eye tissue, invade the paranasal sinuses or the skull, and can be transferred to the ear or submandibular lymph nodes through the lymphatic vessels, and even cause systemic metastases. Occurs frequently in middle-aged and elderly people, and occurs in the skin and mucous membrane transition of the eyelid margin.
