Skin Diseases You Should Know About

Atypical moles, also known as dysplastic nevi, are skin lesions caused by abnormal growth of skin cells that produce pigment. They may develop as new lesions or changes in existing lesions. Atypical moles can be congenital, meaning they develop at birth. Congenital melanocytic nevus is a common form of birthmark. It is a cluster of color cells that develops on the surface of the skin and may also affect deeper tissues.

Pityriasis alba

Pityriasis alba may be self-limiting or require treatment with topical steroids and sunscreen. If the patches are extensive, a treatment with psoralens plus ultravolet A (PUVA) may be prescribed for a limited time. Ultimately, the disease may heal on its own, though it can take months to clear up. A steroid cream may help to reduce dryness and speed up repigmentation.

Pityriasis alba usually clears up on its own without treatment, but many parents choose to get it treated for cosmetic reasons. In the meantime, the rash is best avoided by applying a moisturizer and sunscreen to the affected areas. The itchiness may also be controlled with an over-the-counter hydrocortisone cream.


Vitiligo is a skin disease that is caused by a lack of pigmentation in the skin. This skin disorder has no known cure. However, there are treatments available to help you improve the appearance of affected skin. Treatments vary depending on the severity and location of the disease.

Vitiligo typically starts as a simple spot on the skin, which becomes increasingly pale and eventually white. Patches of vitiligo may have irregular shapes and irregular edges. The most common areas affected are the face, elbows, knees, and back of the hands and feet. However, the disease can affect areas other than the face, such as the eyelids, hair, and mouth.

Those with vitiligo should get regular check-ups with a dermatologist to check for changes in the color of moles and skin tone. This disease can be hereditary or caused by exposure to certain chemicals. While there are no known causes, it may run in families and may be caused by a genetic predisposition to the autoimmune system.

Melanocytic nevus

Melanocytic nevi are benign skin lesions that begin in early childhood and continue to grow throughout an individual’s life. Although they do not require treatment, they are often associated with a small risk of melanoma. Because of this, it is important to monitor CMNs to determine whether they are on the brink of developing into malignancy.

Melanocytic nevi can be congenital or acquired. An acquired nevus is not present at birth, and is blue in color. It can range in size from very small to large, and may be asymmetric or multiple. A biopsy may be necessary to confirm a diagnosis.


Dermatomyositis is a condition in which there is muscle involvement in the skin. It is uncommon in adults and children, and is generally asymptomatic. Symptoms include firm, yellow-white, or skin-colored nodules that may extrude through the skin. These nodules may also lead to secondary infections. In the case of children, dermatomyositis can result in bone formation.

Dermatomyositis is classified as an idiopathic inflammatory myopathy. The traditional management of dermatomyositis is primarily focused on the proximal muscle weakness. However, secondary skin changes are also common and may result in significant morbidity and disability. Hence, proper diagnosis is crucial for the management of this skin disease.

Erythema infectiosum

Erythema infectiosom is a common skin infection in children. It is usually harmless and causes a rash that has a lacy pattern. It may also be associated with a fever. Treatment for the disease focuses on supportive management.

Erythema infectioum is caused by a virus called parvovirus B19. The virus is contagious and is spread through contact with infected individuals or through respiratory secretions. Children with the illness typically develop red rashes on their faces and limbs. The rash can last from a few days to weeks, or sometimes for years. The infection can also affect adults and unborn children.

Erythema may also appear on mucous membranes. Its color and pattern vary based on the type of erythema present and the amount of blood flowing through it. In some cases, the erythema can cause sores or blisters. In severe cases, it can be life-threatening.
