Melanoma and Malignant melanoma Symptoms
Melanoma symptoms and signs:
Melanoma occurs in middle-aged and elderly are more prone male than female. Made a good foot lower extremities, followed by the trunk, head and neck and upper limbs. The main symptoms of Melanoma is rapid growth for the nodular melanoma. Available at the beginning of melanosis occur in normal skin, or pigmented nevi occur more deeper black, followed expanding lesion damage, hardness increased with the feeling pain and itching. Melanoma lesions showed some uplift, plaque and nodular, and some were mushroom or cauliflower-like. To the subcutaneous tissue when the growth of subcutaneous nodules or masses were type to occur four weeks while the proliferation of stellate spots or small nodules. Performance is common melanoma regional lymph node metastasis and worse to the regional lymph nodes and treatment. Advanced by the blood flow to the lungs, liver, bones, organs from the brain.
Symptoms and signs of malignant melanoma:
The beginning of malignant melanoma is a pigmented spots, ranging from brown to black, and often non-uniform color, the depth of different rules is not the edge of the future can be gradually expanded, uplifted into a plaque, nodule or mass, or even diabrosis bleeding, the last shift.
Melanoma symptoms and signs include:
1. color: the majority of malignant melanoma are brown, black, red, white or blue mixed uneven skin mole when the color change appears to be especially vigilant.
2. Edge: serrated change was often uneven, the expansion of tumor spread to the surrounding or self-induced degeneration.
3. the surface: not smooth. Often accompanied by rough and desquamative scales shaped or flake. Sometimes oozing fluid or lesions can be higher than the surface.
4. skin lesions may appear the edema or loss of radiance of your skin or change the original white, gray around skin focus.
5. paresthesia: local often itching, burning or tenderness. When the occurrence of any such changes, prompted a strong malignant melanoma may occur.
According to clinical manifestations, malignant melanoma can be divided into the following four types: in situ melanoma, superficial spreading melanoma, nodular melanoma, lentigo malignant melanoma.
Different types of cutaneous malignant melanoma of the corresponding clinical symptoms:
1. superficial spreading malignant melanoma: the most common, accounting for about 70%. Occurred in about 50 years of age, while women made in the limbs of men occur in the trunk. The degree of malignancy between the freckle and between nodular. Early performance brown, brown, blue or black, most of the rose was red or pink, and its edge was jagged, and the disappearance of skin texture. Radiation continued growth of 1 ~ 12 years, the incidence of lymph node metastasis during the period less than 5%.
2. freckle malignant melanoma: 10% ~ 15% for the four types in a minimum degree of malignancy. Occur in the head, neck, and other exposed parts of the back of the hand, was particularly prevalent in the 60 to 70 years old, mostly women. Clinical performance for larger, flat or slightly higher than the surface of the brown-yellow or brown lesions. When the radiation growth when accompanied by vertical growth, and local uplift was focal, color is still brown, lymph node metastasis rate was 25%.
3. nodular malignant melanoma: In order to grade IV in one of the highest type, accounting for about 12 percent, occurred in about 50 years old, male to female ratio was 2:1, a good hair in the back. Clinical gray with pink color for the nodules, when the lesions continue to grow into a blue color when a black, was jam Forest polyp-like dome-shaped or block-like structures, only the vertical growth of its growth pattern, the rapid disease progression, generally lasted for several months to 1 year, and earlier occurrence of ulcer and lymph node metastasis. Poor prognosis of this type.
4. stain-like acral melanoma malignant melanoma: The main fat in the palms, soles of the feet and a radiation lesion for growth pale brown, brown or black, not above the surface, if a visible pale brown or irregular brown stripes to the proximal nail bed by the expansion of radiation sustained growth of around 1 year and not enter a timely manner to deal with the vertical growth phase, nodular lesions were uplifted, lymph node metastasis rate is increased, prognosis were poor.
