Targetoid hemosiderotic hemangioma, also known as a hobnail hemangioma is a skin condition characterized by a central brown or purplish papule that is surrounded by an ecchymotic halo. [1] [2] It may appear similar to melanoma. It was first described by Santa Cruz and Aronberg in 1988. [2]
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.
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.
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
Gottron's sign is a pathognomonic cutaneous manifestation associated with dermatomyositis (DM), which is an inflammatory disorder affecting the skin and muscles. [1] The primary lesion of dermatomyositis appears as a violaceous, macular erythema with a symmetric distribution, which may progress and become poikilodermatous (atrophic with telangiectasia and pigmentary changes) and indurated (as ...
Common symptoms include pruritic erythematous papules, [3] with a size of 1–3 mm, [4] and a central punctum, [5] as well as macules and urticaria. [2] Individuals frequently describe repeated or long-term episodes of papular outbreaks, often appearing in clusters and accompanied by severe itching sensations. [ 6 ]
The lacrimal caruncle is found at the medial canthus of the eye. [1] It consists of skin, hair follicles, sebaceous glands, sweat glands, accessory lacrimal tissue and other tissues that are present in the skin and accessory lacrimal glands. [1] [2] Its non-keratinized epithelium resembles the conjunctival epithelium. [2]
Porokeratosis may be divided into the following clinical types: [1]: 532 Plaque-type porokeratosis (also known as "Classic porokeratosis" and "Porokeratosis of Mibelli" [2]) is characterized by skin lesions that start as small, brownish papules that slowly enlarge to form irregular, annular, hyperkeratotic or verrucous plaques.
