Actinic elastosis, also known as solar elastosis, is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin, [2] or in the conjunctiva of the eye, [3] which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging.
Annular elastolytic giant-cell granuloma (also known as "Giant cell elastophagocytosis," [1] "Meischer's granuloma," [2] "Miescher's granuloma of the face" [1]) is a cutaneous condition characterized histologically by a dermal infiltrate of macrophages.
Dermatitis is a term used for different types of skin inflammation, typically characterized by itchiness, redness and a rash. [1] In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. [1]
Keratosis pilaris (KP; also follicular keratosis, lichen pilaris, or colloquially chicken skin. [1]) is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps, with varying degrees of reddening or inflammation.
