Three stages characterize the evolution of necrolytic acral erythema lesions: early, well-developed, and late. Scaly, erythematous papules or plaques with a distinctively dark or worn center first emerge. When the lesions reach a well-developed stage, they combine to create a thick, hyperpigmented plaque that is clearly defined and has adhering ...
Annular erythema of infancy (AEI) consists of self-limited eruptions of erythematous, annular to polycyclic patches and plaques. It is an idiopathic figurate erythema. [1] Over several days, a single lesion disappears without leaving behind any scale or hyperpigmentation. Mostly affecting the trunk, face, and extremities, this rash has no symptoms.
Psoriatic plaque, showing a silvery center surrounded by a reddened border. Psoriasis vulgaris (also known as chronic stationary psoriasis or plaque-like psoriasis) is the most common form and affects 85–90% of people with psoriasis. [13] Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery-white, scaly ...
Alopecia mucinosa, also known as Follicular mucinosis, Mucinosis follicularis, Pinkus' follicular mucinosis, and Pinkus' follicular mucinosis–benign primary form, is a skin disorder that generally presents, but not exclusively, as erythematous plaques or flat patches without hair primarily on the scalp, neck and face.
Keratitis–ichthyosis–deafness syndrome (KID syndrome), also known as ichthyosiform erythroderma, corneal involvement, and deafness, presents at birth/infancy and is characterized by progressive corneal opacification, either mild generalized hyperkeratosis or discrete erythematous plaques, and neurosensory deafness.
Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, [1] [2] is a skin disease characterized by the sudden onset of fever, an elevated white blood cell count, and tender, red, well-demarcated papules and plaques that show dense infiltrates by neutrophil granulocytes on histologic examination.
The thicker the scale, the more frequently it breaks free at the edges while staying attached in the middle. The central punctum of the papule frequently develops into a vesiculopustular structure, experiences hemorrhagic necrosis , ulcerates, and is covered in reddish-brown crusts.
Erythrokeratodermia with ataxia is a condition characterized by erythematous, hyperkeratotic plaques with fine, white, attached scales distributed almost symmetrically on the extremities. [ 1 ] See also
