Do you know what types of benign skin tumors there are?

Benign skin tumors refer to skin diseases that grow on various parts of the body surface and usually do not become malignant. As a group of skin diseases, benign skin tumors include pigmented nevi, dermoid cysts, sebaceous cysts, xanthelasma, hemangiomas and other types. The following will introduce the symptoms of these benign skin tumors. I hope it will be helpful to you!

Types of benign skin tumors:

1. Moles are also called pigmented moles. Black moles are the most common. Generally, people will have 20 to 30 black moles of varying sizes. Some are born with them, while others grow later. They are like millet or beans, painless and non-itchy, slightly protruding from the skin surface, and some have hair. There is also a benign skin tumor mole, which is warty or nipple-like papules, or composed of nodules in sheets or lines. It can also have irregular damage, with varying degrees of keratinization and desquamation on the surface, which is clearly demarcated from healthy skin and distributed unilaterally or symmetrically. No matter what kind of mole, it may become malignant after growing for several years, so be vigilant about moles. Especially when a mole is found to suddenly increase in size, change in color, become inflamed and ulcerated, become red, swollen, painful and itchy, and small satellite moles appear around it, it may be malignant. You should seek medical attention immediately, undergo surgical excision and do a pathological examination.

2. Dermoid cysts and epidermal cysts are subcutaneous cystic tumors. The formation principle of this benign skin tumor is that the epithelial tissue or epidermal stratum corneum grows into the cystic cavity. The former can be sucked out with a syringe, and oily substances with a sour smell can be sucked out. Sebum, keratin, hair, fibrous tissue and calcification can be found in the cyst. It is often found in the chest, breast, sacrum, scrotum and other parts. The latter is prone to occur in the head, neck, behind the ears, back and palms and soles. These two benign tumors may also become malignant, so early surgical removal is advisable.

3. Sebaceous cysts are also referred to as "pimples". This benign skin tumor often occurs in the skin and subcutaneous tissue of the head, face, and trunk. It is a single or multiple soft, hard round or oval nodules that are movable. The sebaceous gland openings can be seen on the surface, and white porridge-like substances with a sour smell can often be squeezed out. Once infected, local redness, swelling, ulceration, and pus may occur. Sebaceous cysts are mostly caused by excessive secretion of sebaceous glands or obstruction of sebaceous gland openings. Therefore, people with oily skin or those who do not pay attention to skin hygiene are prone to sebaceous cysts.

4. Xanthelasma and xanthomas. The former is more common in middle-aged and elderly women before and after menopause and patients with hypertension and liver and gallbladder diseases. It is manifested as mung bean-sized or soybean-sized orange-yellow patches at the inner canthus of both upper eyelids, which are higher than the skin. The latter is more common in children and can be nodular, flat or papular, and is prone to occur on the limbs, buttocks, palms, etc. It can be treated with freezing, cauterization or laser, and larger ones can be surgically removed.

5. Hemangiomas are the most common benign skin tumors and are often found after or shortly after birth. The shape, size, and formation principle of hemangiomas vary greatly, and the treatment methods must vary according to the disease and the individual. Generally speaking, when the tumor is small, medication, freezing, laser, radiation, copper needles, etc. can be considered for treatment. When the tumor is large, it should be surgically removed. Hemangiomas can grow with age, but some parents are afraid that their children will suffer from surgery when they are young, so they delay seeking medical treatment, causing the hemangioma to grow larger, the risk of surgery to increase accordingly, and the postoperative effect is often not ideal.

Generally, benign skin tumors are often found on the face, limbs, and hands. In addition to affecting the appearance, they may also cause obvious functional impairment or deformity, bringing great pain to the patient's life. Some benign skin tumors may even turn into malignant skin tumors as they age.
