Inflammatory papular lesions

What Are Inflammatory Papular Lesions?

Inflammatory papular lesions, also known as papulosquamous eruptions, are skin diseases that cause pink, red and scaly spots on the skin. The spots will commonly appear as clusters of small bumps that can vary in size, from just a few millimetres in diameter to larger plaques. In some cases, the lesions may develop into a thick wall of skin. Papular lesions are usually benign (non-cancerous) and can form anywhere on the skin, but they are most commonly found on the arms, legs, face, chest and back.

Types of Papular Lesions

Papular lesions can be classified into different types, based on the underlying cause. These include:

  • Psoriasis – an autoimmune disorder that causes red and scaly patches of skin
  • Pityriasis rosea – a rash that typically appears in the midsection of the body
  • Lichen planus – an itchy, non-infectious rash that typically appears on the arms and legs
  • Seborrheic dermatitis – a red, scaly rash that typically affects the scalp and face
  • Actinic keratosis – a precancerous lesion caused by prolonged sun exposure
  • Folliculitis – an infection of the hair follicles that can cause red bumps on the skin

Diagnosis and Treatment of Papular Lesions

A dermatologist can usually diagnose papular lesions by looking at the skin. In some cases, a biopsy may be required to confirm the diagnosis. Treatment typically involves identifying the underlying cause and then treating it. For example, seborrheic dermatitis can be treated with medicated shampoos or topical creams. Psoriasis may require a combination of topical creams and oral medications.
