Pyoderma, chancreL08.0

Covisa and Berjarano 1927

Chronic pyoderma reminiscent of syphilitic primary (chancre). The diagnosis has largely lost its significance in international literature.

Derby, well demarcated, raised above the skin level, associated with vigorous inflammatory collateral edema, initially superficially eroded, later ulcerated, mies only slightly painful, crusted infiltrate. Regional moderately ductal swelling of the lymph nodes.

Ulcus durum: syphilis serology; lymphadenopathy.

Anthrax of the skin: extremely rare; acute event. At the site of inoculation, development of a less conspicuous red spot: increasing infiltration with then rapid formation of an inflammatory nodule or pustule; rapid spread, hemorrhagic blister; blackish necrosis with considerable collateral swelling. Fever.

Ecthyma contagiosum: ulcers appearing as if punched out. Lower leg

cutaneous leishmaniasis: travel history (where the olive tree grows)

Keratoacanthoma: nodular lesion with central horny plug. No inflammatory quality

Lymphomatoid papulosis: marked chronicity; histology with CD30+proliferates is diagnostic (the forms of "chancroid pyoderma" depicted in many places often correspond to "lymphomatoid papulosis".

Adapted to the situation.

In an early phase of the disease, moist compresses with disinfecting solutions such as polihexanide (Serasept, Prontoderm), quinolinol (e.g., Chinosol 1:1000 or R042 ) or potassium permanganate (light pink) are useful.

Ointment dressings with disinfecting additives such as Polyvidon iodine ointment (e.g. Betaisodona® ointment).

In addition, wound treatment appropriate to the stage.
