A papule is a small, well-defined bump in the skin. It may have a rounded, pointed or flat top, and may have a dip. It can appear with a stalk, be thread-like or look warty. It can be soft or firm and its surface may be rough or smooth. Some have crusts or scales. A papule can be flesh colored, yellow, white, brown, red, blue or purplish. There may be just one or many, and they may occur irregularly in different parts of the body or appear in clusters. It does not contain fluid but may progress to a pustule or vesicle. A papule is smaller than a nodule; it can be as tiny as a pinhead and is typically less than 1 cm in width, according to some sources, and 0.5 cm according to others.

A benign compound nevus occurring most often in children before puberty, composed of spindle and epithelioid cells located mainly in the dermis, sometimes in association with large atypical cells and multinucleate cells, and having a close histopathological resemblance to malignant melanoma. The tumor presents as a smooth to slightly scaly, round to oval, raised, firm papule or nodule, ranging in color from pink-tan to purplish red, often with surface telangiectasia. (Dorland, 27th ed)

丘疹，为局限性、实质性、直径小于1cm的表浅隆起性皮损。丘疹表面可扁平、圆形脐凹状或粗糙不平呈乳头状,颜色可呈紫红色、淡黄色或黑褐色。形态介于斑疹与丘疹之间稍隆起的皮损称为斑丘疹，丘疹顶部有小水泡时称丘疱疹，丘疹顶部有小脓疱时称丘脓疱疹。而斑块则是由丘疹扩大或较多丘疹融合而成的直径大于1cm的隆起性扁平皮损。

丘疹为一局限性隆起皮肤表面的实质性损害，可能是代谢产物的沉积、表皮或真皮细胞成分的局限性增殖，或真皮局限性细胞浸润形成。丘疹在人体皮肤的各个部位都有可能发生，是皮肤病的最基本的皮损类型，见于多种不同的疾病。
