papul

A papule is a small, solid, raised lesion on the skin. Typically, papules are less than 1 centimeter in diameter. They can vary in color, from skin-colored to pink, red, or even brown. The surface of a papule may be smooth or rough, and it can be firm or soft to the touch.

Papules are a common skin finding and can be caused by a wide range of conditions. They are not a disease in themselves but rather a sign of an underlying dermatological issue. Some common causes of papules include acne, insect bites, allergic reactions, viral infections like warts, and inflammatory skin conditions such as eczema or psoriasis.

The exact appearance and accompanying symptoms of papules can provide clues to their cause. For instance, itchy papules might suggest an insect bite or allergic reaction, while papules that develop into pus-filled lesions could indicate acne or a bacterial infection.

Diagnosis of papules usually involves a visual examination by a healthcare professional. In some cases, further investigation such as a skin biopsy or allergy testing might be necessary to determine the precise cause and guide appropriate treatment. Treatment depends entirely on the underlying condition causing the papules.
