Piodermitele secundare au o mare importanta in patologia cutanata deoarece de cele mai multe ori modifica tabloul clinic a numeroase dermatoze, ingreunand diagnosticul precoce al acestora si implicit tratamentul lor.

Piodermitele primitive si cele secundare depasesc 25% din totalul consultatiilor de dermatologie, morbiditatea cea mai mare fiind in randul copiilor.

Autorii au studiat 140 cazuri de piodermite secundare la pacientii internati in Clinica de Dermatologie a Spit. „N. Gh. Lupu" in intervalul iulie 1998 - iunie 1999. Varsta pacintilor a variat intre 6 luni si 80 ani, predominand insa varstele extreme iar repartitia pe sexe a fost egala. Dermatozele cele mai frecvent piodermizate au fost ulcerele cronice de gamba pe fondul insuficientei venoase cronice
(26 cazuri), dermatitele alergice ezematiforme (24 cazuri), scabia si pediculoza (29 cazuri) si dermatofitiile (17 cazuri), dintre care tinea pedis a avut complicatiile cele mai grave - erizipel si limfagita, celulita.

Piodermitele grave la pacientii atopici sunt prezentate detaliat cunoscandu-se rolul de superantigen al Staph. auriu hemolitic si implicatiile acestuia in aptogenia bolii. Piodermitele subnevice pun de asemeni probleme de diagnostic si tratament.

Autorii subliniaza in concluzie aspectele actuale ale piodermitelor avand in vedere si asocierea acestora cu sindromul de imunodeficienta dobandita.

Secondary bacterial infections are a very interesting chapter of skin pathology because they change clinical aspect of the basic dermatosis and the early diagnosis is more difficult.

Primary and secondary piodermas represent more than 25% of the total dermatologic clinical examination and the greatest morbidity is in children.

The authors studied 140 cases of secondary pyodermas between July 1998 - June 1999 in the patients of Dermatologic Department of "N. Gh. Lupu" Hospital. The greatest morbidity was in childhood and in the older patients. The most proeminent complicating preexisting skin lesion were: 26 cases of ulcus cruris, 24 cases of allergic dermatitis, 20 cases of scabia and pediculosis, 17 cases of dermatomycoses.

Severe cases of pyodermas in atopic patients are also presented, usually associated with Staph. aureus which is known as an superantigen and which may trigger or aggravate atopic dermatitis. The subnaevus pyoderma is very interesting in differential diagnosis with malignant melanoma.

The treatment is more difficult in immunodeficient patients.
