[ 30 ] Plaque : A plaque has been described as a broad papule, or confluence of papules equal to or greater than 10 mm, [ 30 ] or alternatively as an elevated, plateau-like lesion that is greater ...
It is most common on skin exposed to mechanical abuse—wear and tear—such as the upper and lower extremities. Patients experience papules, pustules, or even plaques and nodules at the infection site. [3] The white to red papules and pustules often have a perifollicular location. Hair shafts can be easily removed from the pustules and papules ...
The symptoms of a disseminated gonococcal infection include fever, tenosynovitis, arthralgias, and a few vesiculopustules over the distal ends of the extremities that may have purpura or hemorrhagic necrosis. The symptoms of Rocky Mountain Spotted Fever, which is spread by ticks, include photophobia, headache, fever, chills, and myalgias.
The dermis is the layer of skin between the epidermis and subcutaneous tissue, and comprises two sections, the papillary dermis and the reticular dermis. [10] The superficial papillary dermis interdigitates with the overlying rete ridges of the epidermis, between which the two layers interact through the basement membrane zone. [10]
Perioral dermatitis is frequently histologically similar to rosacea with the two conditions overlapping considerably. There is a lymphohistiocytic infiltrate with perifollicular localization and marked granulomatous inflammation. Occasionally, perifollicular abscesses may be present when pustules and papules are the dominant clinical findings. [7]
A papule can be flesh colored, yellow, white, brown, black, blue or purplish, or varying shades of red. [4] [6] The intensity of redness might indicate how long the papule has been present. [6] There may be just one or many, and they may occur irregularly in different parts of the body or appear in clusters. [2] It may progress to a pustule or ...
The main symptoms and signs of a skin abscess are redness, heat, swelling, pain, and loss of function. There may also be high temperature (fever) and chills. [15] If superficial, abscesses may be fluctuant when palpated; this wave-like motion is caused by movement of the pus inside the abscess. [16]
Often intensely itchy, the red papules and pustules can also be associated with blisters and scales and are always remote from the primary lesion. [5] It is most commonly a blistering rash with itchy vesicles on the sides of fingers and feet as a reaction to fungal infection on the feet, athlete's foot. [6]
