Shankriform pyoderma is a bacterial infection of the skin resembling a syphilitic chancroid.
Causes and pathogenesis of shanriciform pyoderma. The causative agent of the disease are staphylococci and streptococci. The disease develops with a decrease in the defenses of the body (the state of immunodeficiency) and the irrational therapy of the underlying disease (scabies, etc.)
Symptoms of shanriciform pyoderma. The disease often begins with the appearance of a bubble, after the opening of which there is erosion or ulcer. Ulcers of round or oval shape, the bottom is even, pink-red in color, with raised edges, with a slight purulent discharge. In most cases, lesions are covered with hemorrhagic crusts of different thicknesses. On the periphery of the focus can be a narrow inflammatory rim. The sizes of ulcers are comprehended in diameter 1-2 cm. The ulcerative defect has a seal in the base. However, unlike a solid chancre, a dense infiltrate with shan-formiform pyoderma goes beyond the ulcer defect. Subjective sensations are absent. Regional lymph nodes are dense, painless, not welded together and with the underlying tissues. The lesion is single, but can be multiple. Simultaneously, in patients other than shanriciform pyoderma, there may be other eruptions of pyoderma. In eradicable erosion or ulcers, staphylococci and streptococci are commonly found. For the exclusion of syphilis, careful investigations of the separated ulcers on pale treponemia and serological studies are necessary.
Histopathology. Significant acanthosis, edema, proliferation of lymphatic and blood vessels, perivascular and diffuse infiltrate, consisting of polymorphonuclear neutrophils, eosinophils, lymphoid elements and histiocytes are noted.
Differential diagnosis. Shankriform pyoderma should be differentiated from syphilitic chancre, soft chancre, venereal lymphogranuloma, etc.
Treatment of shanriciform pyoderma. Assign antibiotics of a wide spectrum of action (sispres, kefzol, cloforan, etc.), sulfonamides, topical aniline dyes, antibacterial and antiseptic ointments.
