Histoplasma Duboisii

In fact, Histoplasma duboisii is acquired mostly through skin opening and the digestive route [10]. Dissemination of Histoplasma duboisii through bloodstream or lymphatic system might explain its multiple locations. [scirp.org]
The latter was proved by culture and histopathology to be due to Histoplasma duboisii. The fungus was confined to the skin. H. duboisii may be more prevalent, and further studies in Dindir area are needed. [ncbi.nlm.nih.gov]

Treatment
Typical treatment of severe disease first involves treatment with amphotericin B, followed by oral itraconazole.Liposomal preparations of amphotericin B are more effective than deoxycholate preparations. [en.wikipedia.org]
Both patients with cutaneous disease responded to treatment, although one was lost to follow-up. [ncbi.nlm.nih.gov]
Treatment options are not yet well codified. But medical treatment is the first alternative and may include surgery or contention with brace. Amphotericin B, ketoconazole and itraconazole are the most used molecules. [scirp.org]
Prognosis
It is worth considering this pathology at least for three reasons: it usually mimicks a malignant jaw tumor; it may constitute a migrant pathology; and prognosis is commonly favorable with amphotericin B treatment. [ncbi.nlm.nih.gov]
What is the prognosis of histoplasmosis? People with mild symptoms of histoplasmosis usually resolve the disease on their own without treatment. In more severe cases, the prognosis is good for those who receive appropriate treatment. [medicinenet.com]

Prevention
There is no vaccine or preventive medication against Histoplasmosis. Information last updated: December 11, 2017 [iamat.org]
How Can One Prevent Histoplasmosis? There is no vaccine to prevent histoplasmosis. The CDC recommends people "avoid areas with accumulations of bird or bat droppings, especially if you have a weakened immune system. [emedicinehealth.com]
Prevention and Vaccine: The Centers for Disease Prevention and Control recommend avoiding areas that may have bat droppings or bird guano, specifically people who are immunocompromised. [7] Also, workers with high-risk exposure should practice safe precautions [austincc.edu]
The maintenance phase is directed at preventing relapse. [hivinsite.ucsf.edu]
