Lesione
Scegliere le efflorescenze giuste:
An erosion is a superficial non-scarring defect.
There is a bizarre ulcer with fibrinous debris and islands of re-epithelization.
No vesicle or blister is seen.
A fissure is a long thin defect, not seen here.
Diagnosi
Scegliere la diagnosi giusta:
Uncommon sexually transmitted disease, usually seen in tropical lands, but occasionally epidemics in focal areas in Western lands. Caused by Calymmatobacterium granulomatis.
Herpes simplex can cause big ulcers, especially in HIV-infected patients, but otherwise the lesions are more superficial.
Burns usually spare the body folds, and there is no history.
Hidradenitis suppurativa involves the groin and axillae. Individual lesions look like boils and heal with fistulas and scarring.
Artifact is a diagnosis of exclusion, but this lesion really does not appear self-induced. Often such lesions are a bit too linear or rectangular, if made with an instrument, or look splattered if made with a caustic.
Terapia
Scegliere la o le terapie giuste:
This the is recommended regimen for granuloma inguinale, which responds well. Healing with scarring is anticipated.
Surgical treatment is not indicated. The antiobiotic regimen is that for neurosyphilis and is not indicated here.
This is another possible approach.
There is no good topical therapy for granuloma inguinale. In addition, the peroxide would be so painful that the patient would not complete the treatment.
