Lichenoid drug eruption

Lichenoid drug eruption is a skin disorder that is characterized by the appearance of lichen planus-like rashes due to certain medications. It is also known as drug-induced lichen planus.

Causes

Lichenoid drug eruption is caused by a reaction to certain medications. These can include nonsteroidal anti-inflammatory drugs (NSAIDs), antimalarials, beta-blockers, and certain diuretics. The exact mechanism of how these drugs cause the reaction is not fully understood.

Symptoms

The symptoms of lichenoid drug eruption are similar to those of lichen planus. They include flat-topped, shiny, violet-colored bumps on the skin. These bumps can be itchy and painful. The rash usually appears on the wrists, ankles, and lower back, but can appear anywhere on the body.

Diagnosis

The diagnosis of lichenoid drug eruption is usually made based on the appearance of the rash and the patient's history of medication use. A skin biopsy may be performed to confirm the diagnosis.

Treatment

The treatment for lichenoid drug eruption involves discontinuing the medication that caused the reaction. Topical corticosteroids may be used to help reduce inflammation and itching. In severe cases, oral corticosteroids may be needed.
