Papula is a medical term that refers to a small, raised, and usually solid skin lesion. These lesions are typically less than one centimeter in diameter and can vary in color, ranging from pink to red or even brown. Papula is derived from the Latin word "papulae," which means pustule or blister.
Papula is a common characteristic of various skin conditions and diseases, including acne, eczema, psoriasis, and certain types of dermatitis. They can also be associated with insect bites or allergic reactions.
Papula formation can occur due to a variety of factors. It may result from an infection, such as the formation of a papule in acne caused by the accumulation of dead skin cells, oil, and bacteria in hair follicles. Alternatively, papulae can develop as a response to an allergen or irritant, leading to an inflammatory reaction in the skin.
The appearance of papulae can vary depending on the underlying cause. Some may be dome-shaped, while others may appear flat or even blistered. Papulae are usually palpable, meaning they can be felt when touching the affected area of the skin.
Although papulae typically resolve on their own over time, treatment options may be necessary depending on the underlying cause and the severity of symptoms. Treatments may include topical medications, oral medications, or interventions like cryotherapy or surgical removal.
Overall, papula is a term used in dermatology to describe a small, raised skin lesion that can be caused by various conditions or factors.
