A lesion is an area of tissue that has been damaged or an area of skin with different color or texture than the skin surrounding it, particularly due to injury or disease.
It can occur anywhere in your body including the scalp, brain, face and so forth. It can cover a tiny or larger area depending on the cause. They can also be singular or numerous, localized (confined to a specific area) or generalized (widely distributed).
Those in this area can be in the form of blisters, swellings, bumps, rash, cysts, pus-filled sacs, discolorations, hardenings or more changes in or on the scalp skin.
Since there are many causes, understanding them may be quite complicated, their symptoms can range from relatively harmless to life-threatening. According to Drugs.com, lesions may itch, bleed, hurt or fluid-filled.
Just as we had mentioned, they have many causes. The widespread causes are an injury to the scalp, infectious diseases, allergic reactions or damage to hair follicles. Chronic diseases such as diabetes or autoimmune disorders are also among the common causes. Read on to explore more on the causes.
What is lupus? Well, according to Resources.lupus.org, “Lupus is a chronic autoimmune disease that can damage any part of the body (skin, joints, and/or organs).” It happens when the body’s natural immune defense system attacks healthy tissue instead of attacking only the invaders such as bacteria, viruses, and germs. This will cause inflammation, pain, and damage in various parts of the body including the scalp hence lead to lesions such as scalp bumps, cysts, rash and more.
The certainty about what causes lupus is not yet verified but it has been linked to inherited genes in some people. Other factors that are considered to trigger lupus include viral infections and sunlight.
Symptoms of lupus vary widely but common symptoms include swelling, scalp rash, hair loss, fever and more. Over time, the patient living with lupus may develop severe symptoms such as disorders of kidney, heart, lungs, blood cells or nervous system.
Lupus diagnosis will include physical examination, questions about your medical history or urine and blood test.

- Neonatal lupus: this is a rare type of lupus that often affects newborns
Both allergens and irritants are common causes of many skin lesions including one this part of the body. Common types of allergy that can lead to them include food allergies, allergies to certain medications or contact dermatitis (allergic eczema) such as reaction to certain hair care chemicals.

Systematic illness such as cancer and diabetes can also cause changes in skin color or texture and sore among other lesions. The reason may due to poor wound healing or poor blood circulation on the scalp. These diseases can also weaken the body immune system hence making skin here skin vulnerable to many skin infections.
Scalp Acne Lesions
These bumps or lesions formed by the collection of excess sebum and dead skin cells that block the hair follicles. When these bumps become infected, the resulting symptoms may be very severe.

Scalp conditions are frequently seen throughout childhood actually from infancy all through to puberty. There are several causes that may lead to these conditions. Usually, rashes, birthmarks, and other scalp skin conditions are experienced in infancy and many of such scalp conditions can just be benign that require no treatment. However, keen evaluation and close follow-up should employ to ensure no negative outcome.
Remember, there are situations where their appearance in a newborn can pose serious symptoms or can indicate a certain life-threatening condition that must be responded to immediately. Below are the conditions to consider in the various diagnosis of scalp lesions in the newborn:
Trauma from scalp electrode monitor
Usually, during labor, an electrode is placed on the baby scalp to continue to monitor fetal heart rate. This device requires some skin penetration levels.
Accidentally, trauma can occur during the placement or removal of the electrode and this can lead to an open wound. When secondary infections precede this, a large or deep scalp lesion may happen.
Aplasia cutis congenital
Aplasia cutis congenital is another common condition in a newborn that lead to small lesion characterized by ulceration. The lesion only affects the epidermis and partly dermis and usually heal perfectly.
Unfortunately, the lesions form a scarred area that doesn’t grow hair and they can be frequently affected by persistent scaling in childhood. The cause it this condition is not known but have been linked with teratogens and premature rupture of membranes
Going on with causes them in kids, especially newborn or infants is neonatal herpes. This condition is acquired during virginal delivery if the mother is shedding has simplex virus during this stage. The scalp lesion may present with erosions and vesicles that are on the skin surface and crust rapidly.

Such causes are usually not usually accompanied by lesions on scalp. More causes in the same category include chemotherapy, malnutrition, HIV/AIDS, and hypothyroidism.
On the other hand, we have causes of hair loss that usually accompany inflammation and scarring. These causes of hair loss can also result in bumps on the scalp because of inflammation and scarring. Therefore, this is why a lesion can be a symptom of hair loss or vice versa.
We also have to acknowledge that lesions are mostly are associated with temporary hair loss, the hair will start to grow again after lesions have healed. However, there are cases where some scalp lesions also result in permanent hair loss in the affected areas.
