The central punctum of the papule frequently develops into a vesiculopustular structure, experiences hemorrhagic necrosis, ulcerates, and is covered in reddish-brown crusts. There may be postinflammatory hyper- and hypopigmentation as well as varioliform scars.
Fibrous papules are also termed facial angiofibromas and were formerly and incorrectly termed adenoma sebaceum (fibrous papules are unrelated to sebaceous glands [4]). They develop in up to 8% of the general adult population and occur as 1 to 3 [5] pink to red, [4] dome-shaped papules in the central areas of the face, nose, and/or lips. [6]
A papule may have a rounded, pointed or flat top, and may have a dip. [2] It can be polygonal but is never rectangular or square. [6] It can appear with a stalk, be thread-like or look warty. [3] Ulceration, oozing, bleeding or thin blood vessels may be present in a papule. [6] It can be soft or firm and its surface may be rough or smooth. [2]
Stasis papillomatosis is a disease characterized by chronic congestion of the extremities, with blood circulation interrupted in a specific area of the body. [1] A consequence of this congestion and inflammation is long-term lymphatic obstruction . [2] It is also typically characterized by the appearance of numerous papules. [3]
A maculopapular rash is a type of rash characterized by a flat, red area on the skin that is covered with small confluent bumps. It may only appear red in lighter-skinned people. The term "maculopapular" is a compound: macules are small, flat discolored spots on the surface of the skin; and papules are small, raised bumps.
In dermatology, a target lesion or bull's-eye lesion, named for its resemblance to the bull's-eye of a shooting target, is a rash with central clearing. It occurs in several diseases, as follows: Target lesions are the typical lesions of erythema multiforme, in which a vesicle is surrounded by an often hemorrhagic maculopapule. Erythema ...
Usually appearing as a cluster of erythematous papules and papulo-pustules, the lesions are umbilicated, 2-4 mm in diameter, and develop central necrosis within a few days. An adherent hemorrhagic crust forms, but it falls off after 3–4 weeks, leaving varioliform scars.
Discrete papular lichen myxedematosus is typically identified by the presence of violaceous, flesh-colored, or reddish, waxy papules that range in size from 2 to 5 mm and that symmetrically affect the trunk and limbs.
