Diffusion transfer method of skin cancer

Diffusion transfer method of skin cancer

Diffusion transfer method of skin cancer:

    
Diffusion transfer method of skin cancer, what does? You know the spread of skin cancer metastasis way? The following describes cnaizheng "diffusion transfer method of skin cancer":

    
Mainly through blood and lymph node metastasis. Skin cancer usually spread through blood.

    
(1) lymphatic system: lymphatic invasion of cancer cells, the flow with the lymph nodes, where the formation of new cancer, will revert to other lymph node metastases.

    
(2) hematogenous metastasis: cancer cell invasion of capillaries, the body can flow with the blood weeks, the formation of new lesions. Venous invasion of cancer cells before transfer to the lungs, and then throughout the body; digestive tract cancer cell invasion of the portal vein first, and then transferred to the liver; vertebral venous system and the lumbar, sacral, thoracic and abdominal anastomosis between the veins, etc. Traffic branch, no vein graft, and directly to the spine, pelvis and brain metastases.

Clinical manifestations of squamous cell carcinoma

Clinical manifestations of squamous cell carcinoma
Clinical manifestations of squamous cell carcinoma:

    
Squamous cell carcinoma of the clinical manifestations, what does? You know squamous cell carcinoma of the performance? Cnaizheng described below, "squamous cell carcinoma of the performance":

    
Squamous cell carcinoma accounts for about 90% of skin cancer. 30 to 50 years old and more hair. Often by keratosis, leukoplakia and other precancerous conditions transformed. Since the beginning of the dark red, hard, higher than the leather of the nodules, the surface of the cuticle after shedding a red erosion surface, accompanied by bleeding, exudate, lesion gradually expanded. Rapid growth, early that the formation of ulcers. Some were nodular or cauliflower-like, to the deep violation of smaller, portable base; some were butterfly-shaped, deep infiltration of the obvious, devastating, often involving the bone. Squamous cell carcinoma is often accompanied by purulent infection, with odor, pain. Common regional lymph node metastasis, large squamous cell carcinoma, the stench very, purulent secretions are more easily bleeding; the risk of neck lymph node metastasis. The predilection for mucocutaneous junction of the fastest growing squamous cell carcinoma, mucosal disease are more likely to transfer.

    
Most squamous cell carcinomas occur in chronic ulcers, leukoplakia, coloring on the basis of diseases such as dry skin. Good site for the eyelids, nose, lips, temporal, cheek, forehead, limbs, foreskin, glans, trunk may also occur. Compared with basal cell carcinoma, squamous cell carcinoma of the development of rapid, easy a transfer. According to statistics, transfer of lower limbs are more skin cancer, followed by hand back and face and neck, a rare blood metastasis, lung metastasis is the most common organ. Damage to the slow development of basal cell carcinoma, regional lymph node metastasis usually rare, and no distant metastasis.

    
Generally divided into 4 types, the most common is the nodular ulcerative type.

    
1, nodular ulcerative type: since the beginning of the epidermal to the emergence of a small pea-sized grain of rice, wax-like nodules, very hard texture, the surface expansion of a small number of capillaries, slightly out of the skin surface, or just do not like erythema and uplift, or slightly nodular surface of the skin with mild depression down. Nodules can be gradually expanded or new lesions appear, fused with each other, forming a disk-shaped wax-like luster plaques, often forming the central brown, brown or dark gray mark, and then scab occurs ulcer, gradually expanded to form round, oval or plastic ulcers, size of a ring or coins that range, marginal ulcers, and rolled up a solid, often translucent and uneven skin inflammation around the bottom was pearl-like or wax-like appearance, sometimes damage to the surface completely covered by callus. Ulcers and deep slow expansion to the surrounding, such as rat-bite-like, forming a typical basal cell carcinoma clinical form, named for the erosion of ulcer, ulcer scar may be part of the healing occurs, also be extended to the subcutaneous tissue and even cartilage and bone. Organizations can be destroyed from the pit-like. Occurs on the face can damage the nose, ears, eyes and maxillary sinuses and other parts of the cartilage and bone tissue, causing bleeding or intracranial invasion or mutilation.

    
2, pigment type: nodules of relatively shallow, the same damage and nodular ulcerative type. Because it contains more pigment, damage to the edge of a pearl luster addition, there are point-like or reticulate dark brown or dark brown pigment spots, the central parts of pigmentation is also visible, exposing callus easy bleeding, dark brown crust and even under carbon black particles, similar to malignant melanoma, easily misdiagnosed.

    
3, hard porphyritic or fibrosis type: common in head and neck, as the hard yellow or yellow-white patches, slightly elevated, ill-defined, it seems like a hard spot disease can be maintained long-term integrity and ultimately ulceration.

    
4, superficial: superficial skin lesions, occurred in the trunk, one or a few pieces were infiltrated erythema, scaling, or crusted surface, edge or the entire lesion is slightly elevated, at least part of a small pearl-like edges or lines dike-like shape. This type may eventually fibrosis. Like psoriasis, eczema or seborrheic dermatitis. Damage to the slow development of basal cell carcinoma, regional lymph node metastasis usually rare, and no distant metastasis.


  

Treatment for basal cell carcinoma

Treatment for basal cell carcinomaTreatment of basal cell carcinoma:

    
Treatment of basal cell carcinoma, what does? You know the treatment of basal cell carcinoma it? Cnaizheng described below "basal cell carcinoma treatment":

    
Treatment of basal cell carcinoma 1, surgical treatment: apply to all of skin cancer, all tumors should be completely removed. Advanced squamous cell carcinoma with deep invasion or lymph node metastasis, the need for regional lymph node dissection. Before and after surgery should be considered systemic chemotherapy or regional perfusion chemotherapy.

    
Treatment of basal cell carcinoma 2, radiotherapy: basal cell carcinoma is very sensitive to radiation. Squamous cell carcinoma is only moderately sensitive to radiation. High cure rate in patients with early radiotherapy. Radiotherapy is also applicable to the site of lymph node metastases before and after surgery for adjuvant therapy.

    
Treatment of basal cell carcinoma 3 and chemotherapy: the rule of law as a comprehensive one, or palliative therapy.

    
Treatment of basal cell carcinoma 4, anti-cancer traditional Chinese medicine as a comprehensive treatment of one of the measures that are not suitable for surgery and radiotherapy and chemotherapy or relapse after surgery.
