INTRALESIONAL INJECTIONS Meaning and
Definition
-
Intralesional injections refer to a medical procedure involving the direct administration of drugs or medications into a specific area or lesion within the body. These injections are typically performed using a fine needle, which allows the medication to be delivered directly into or near the target area.
This technique is commonly used in dermatology, specifically to treat various skin conditions, such as cysts, warts, keloids, psoriasis, and acne. By injecting medication directly into the affected area, intralesional injections provide a localized treatment option that can minimize side effects compared to systemic treatments.
The injected medication can vary depending on the specific condition being treated. For instance, corticosteroids are frequently used to reduce inflammation and suppress immune responses in conditions like psoriasis or keloids, while chemotherapeutic agents may be employed to target and destroy cancerous cells in certain types of skin cancers.
Intralesional injections are typically performed in a clinical setting by healthcare professionals, including dermatologists, plastic surgeons, or other specialists. The injections are administered under sterile conditions to minimize the risk of infection or other complications. The number and frequency of injections can vary depending on the patient's response to treatment and the severity of the condition being treated. Close monitoring is often required to assess the efficacy of the injections and to manage any potential side effects.

Etymology of INTRALESIONAL INJECTIONS
The word "intralesional" consists of two parts: "intra-" and "lesional".
1. "Intra-" is a prefix derived from Latin, meaning "within" or "inside". It is commonly used in medical terms to indicate a procedure or treatment performed inside a specific location or area of the body.
2. "Lesion" comes from the Latin word "laesio", meaning "injury" or "damage". In medical terminology, a lesion refers to an abnormal change or tissue damage caused by disease, injury, or trauma.
Therefore, the term "intralesional" describes an injection that is administered directly into a localized area of tissue damage or lesion rather than into a vein, muscle, or other broader anatomical site.
"Injections" refer to the act of introducing a substance, usually a medication or therapeutic agent, into the body using a needle and syringe.
