Very often, on the surface of the skin, besides the usual moles or eels, strange tumors can be observed. The appearance of a growth of uncertain nature should cause concern and become a pretext for immediate visits to a dermatologist. Neoplasms can carry a number of problems, including the development of skin cancer. Even the most innocent warts must be checked by a doctor for goodness. What are the types of skin growths and what they threaten.
Types of growths
Skin growths are divided into three main groups – benign, malignant and precancerous. And each group has its own subspecies.
Such neoplasms on the skin do not pose a direct threat to their wearer, unless they are subjected to various kinds of mechanical effects.
Cutaneous neoplasm, which is formed during the blockage of the sebaceous glands. Externally, the growth resembles a small dense bump, with a clearly defined contour. Such a bump to the touch is very elastic and mobile. When probing does not cause pain and other discomfort. A lump can suppurate and even break through. At breakthrough, a purulent-sebaceous fluid is released from the growth. During the period of inflammation, the temperature rises, atheroma can hurt. An eruption is formed in places of a large accumulation of sebaceous glands – on the scalp, neck, back, in the groin area.
A hemangioma is a vascular tumor, it can be:
- Capillary – growth on the surface of the skin, can reach large sizes. Color from red to bluish. Often grows to the side.
- Tricky – limited subcutaneous knotted growth. The skin in the area of tricky hemangioma usually turns red. Such tumors often appear in newborns in the neck and head.
A tumor that develops on the walls of the vessels of the lymphatic system. The tumor is characterized by very slow growth. In the lymph nodes grows exaggerated skin tumor, it is painless. The neoplasm is cystic, consisting of several isolated or combined cysts. The disease mainly affects children, but can also develop in adults. This disease usually occurs in the fetus during fetal development. The disease is not dangerous, but it tends to grow instantly under the influence of adverse environmental factors. In this case, immediate surgical excision is required.
Lipoma or Wen
A neoplasm that develops under the skin from fat cells. Externally, the wen looks like atheroma. Subcutaneous bump is completely painless. It feels like a hard and moving ball when probing. Lipoma can develop anywhere on the body where there is subcutaneous fatty tissue. Anger is single or multiple. One wen can grow in size from a large pea to an average sized apple. The tumor brings its owner aesthetic discomfort.
Papillomas and warts
Skin galls that form from epithelial tissue. Such growths can be spherical (in the form of a papilla), horny (filiform) or flat. Neoplasms are small, painless. Can develop anywhere on the body. The growths can be flesh-colored, brown, red and even black. The appearance of warts indicates the presence in the body of HPV – human papillomavirus.
Nevus and moles
These are congenital or acquired flat growths in the form of one or several spots. Such growths are small or large clusters of cells that are overflowing with the natural coloring pigment – melanin. Neoplasms can be different in color (from beige to dark brown), texture, shape and size. Such growths do not bear special harm to health.
Scaling, which is formed from a cluster of connective tissue. Externally, the fibroma resembles a wart on a thin stalk. An eruption is similar to a collection of small spherical skin nodes. The surface of the fibroids can be smooth or loose. The growth color varies from solid pink to dark brown. Fibroma grows very slowly, does not cause discomfort (except for mechanical inconvenience caused by clothing or the place of its location). If there is no effect on the fibroid, it is safe.
A cutaneous neoplasm that is formed from nerve cells. Most often develops on the basis of stress and nervous over-excitement. Often the growth is located in the area of fatty subcutaneous tissue and under the skin itself. Externally, the tumor is a dense tubercle, with a pigmented outer skin ball. Nodos quickly grow on the skin, very rarely alone. Most often, the back, neck, elbows and knees are affected.
This category of skin lesions often appears by transforming a benign growth into a malignant one. Such growths require immediate identification and disposal of them.
Neoplasm arising as a result of incorrect removal of a mole (nevus) or its degeneration into a malignant form. Melanoma is a type of skin cancer. The disease is very aggressive, quickly spreading over the skin. Such a tumor very soon gives metastases throughout the body, to the internal organs and even to the brain.
Squamous cell skin cancer, which is formed from the cells of the basal layer of the epidermis, in the form of flat, single purulent wounds. Small nodular wounds — tumors rapidly progress and develop into mushroom-like ulcerous growths. Most often, wounds appear on the face, the cheeks, the wings of the nose, the area behind the ears and the ears, the lower eyelid are affected. This type of cancer does not metastasize to the internal organs and does not diverge strongly on the skin.
A malignant neoplasm on the skin in the form of extensive dark spots (from the color of boiled blood clots to black), which merge into large areas of damage. The disease is diagnosed in most cases in HIV-infected people, in the later stages of the course of the disease. Sarcoma lesions: hands, legs and feet. This disease is a consequence of serious problems with internal organs, it can not be cured, you can only remove a little drug-induced symptoms.
A tumor that occurs as a result of damage to adipose tissue. This is a large subcutaneous rounded growth (single knot), it can grow up to 20 centimeters. By itself, the growth is uneven, with irregular outlines. When probing can be firm and elastic. This growth often occurs in people over the age of 50 years and mostly in men. Liposarcoma occurs by degenerating a lipoma or atheroma into a malignant tumor. The growth is growing very slowly, does not spread metastases to internal organs.
The new growth developing in connecting soft tissues. Most often the growths affect the skin of the lower extremities.
Fibrosarcoma can be placed externally or subcutaneously. The cutaneous appears above the skin, such a growth has clearly visible borders and a dark blue or brown tint.
Subcutaneous fibrosarcoma is located deep under the skin and unobtrusive. We see only a small venous tubercle.
Despite the terrible name of the category, most of these tumors, if quickly identified, can be removed and cured without serious harm to health.
At the initial stages of tumor development, it is located in the upper layers of the epidermis. On the skin appears clearly delineated plaque brownish hue, with flaky surface. Under its surface is hidden weeping purulent layer of the epidermis. Often the disease develops after 40 years, mainly in men. Bowen’s disease affects the genitals, the skin of the face, hands, and oral mucosa. If you do not identify the disease in time and do not begin treatment, it starts up metastases and enters the stage of invasive cancer. Treatment is usually carried out topically, by medication.
The disease develops through the regeneration of pigment spots. Occurs in people with hypersensitivity to the negative effects on the skin of solar ultraviolet rays. This pigmentation is most often seen on the skin of the hands, face, back and chest. It thickly covers the entire skin with dark brown spots. Spots can act as growths over the surface of the skin and contain purulent blood malaria.
An eruption resembles a rash first, after an accumulation of small skin spherical nodes that are connected to a common spot. Over time, the flat outgrowth becomes dense loose crust on its surface. At the initial stage of development, the growth of the skin color, in the process of progression, darkens to brown. The upper scales of keratoma may flake off, the wound begins to bleed.
Formed by the growth of epidermal cells of the thorny skin layer. A cone-shaped elevation forms on the skin, which looks like a small horn. The horn has a multi-layered and scaly structure. Usually, a dry growth appears in the elderly behind the ears, on the fingers and toes, on the feet, and in the hardened parts of the skin.
