#skin lesion

• Friction lesion — An archaic or regional term used in Romanian folk medicine to describe a superficial traumatic lesion, a bruise (ecchymosis), an inflamed callus, or an excoriation produced by friction, impact, or prolonged compression on soft tissues. In early medical reports or rural forensic evaluations, the word served as an empirical descriptor for minor skin trauma or localized edema occurring after wearing improper work equipment.
• Angiokeratoma — A benign skin lesion histologically characterized by marked dilation of capillary vessels in the superficial dermis, accompanied by reactive hyperkeratosis (thickening of the horny layer) of the overlying epidermis. Clinically manifested as small, hard, red-purple or blackish papules, this structural formation can appear isolated, in localized clusters, or as a systemic manifestation in rare genetic metabolic disorders, such as Fabry disease.
• Angiokeratosis — A well-defined systemic or dermatological pathological state, characterized by the appearance and development of multiple angiokeratoma-type lesions across extensive areas of the body. This structural phenomenon involves capillary ectasias associated with hyperkeratotic changes of the epidermis, often correlated with inborn errors of metabolism, such as lysosomal storage disorders.
• Angiolupoid — A rare clinical form of cutaneous sarcoidosis (structurally known as Brocq-Pautrier angiolupoid), characterized by the appearance of well-defined, infiltrated plaques or nodules, reddish-purple or brown in color, typically localized on the nasal pyramid or the inner canthus of the eye. Histologically, this lesion is distinguished by the association of a typical sarcoid (tuberculoid) granulomatous infiltrate with an intense component of neoangiogenesis and pronounced capillary vascular ectasias.
• Anthracoid — Resembling coal, possessing the appearance, color, or structure of a coal pustule (anthrax) or displaying the exterior physical characteristics of anthracite. In a clinical medical sense, it describes a cutaneous lesion, a black ulceration, or a severe dermatological reaction that, through its geometric configuration and central necrotic hue, partially mimics the structural evolution of a pathogenic anthrax infection without being directly caused by that specific bacillus.
