RED PAPULE, ACUTE

By Gary M. White, MD


It is very common for people to develop a single, red, inflamed papule or papulonodule. The face is a common location. Rarely is this cancer. Acne, a bug bite, folliculitis, ruptured cyst etc., all may be found. Watchful waiting for a few weeks usually allows for the lesion to resolve spontaneously. There is no hard and fast rule, but single lesions growing past say a month should be considered for a biopsy to rule out squamous cell carcinoma.
