Ecthyma a purulent skin disease caused mainly by streptococci penetrating the skin after minor trauma. The development of the disease is promoted by lowered resistance, metabolic disorders, and vitamin deficiency. A blister forms on the skin, most commonly on the legs. It has an inflammatory infiltrate at the base and purulent or purulent-bloody contents that dry into a crust which, after falling off, reveals a painful ulcer with steep edges and an uneven bottom covered by pus. Ecthyma heals gradually, leaving a scar. Treatment consists in the application of disinfectant and epithelizing ointments. In severe cases, when deep, multiple eruptions occur, antibiotics are administered. Prevention requires treating bruises with disinfectant solutions. ecthyma Note: This page may contain terms or definitions that are offensive or inappropriate for some readers.ecthyma [ek-thi´mah] an ulcerative pyoderm usually caused by group A beta-hemolytic streptococcal infection at the site of minor trauma, predominantly involving the shins and feet, and generally healing with variable scar formation.ecthyma gangreno´sum a condition most often seen in debilitated patients in association with septicemia caused by gram-negative organisms, characterized by lesions that begin as vesicles that rapidly progress to pustulation and gangrenous ulcers with undermined purpuric edges.ec·thy·ma (ek-thī'mă), A pyogenic infection of the skin initiated by β-hemolytic streptococci and characterized by adherent crusts beneath which ulceration occurs; the ulcers may be single or multiple, and heal with scar formation.
