Report of a new American histoplasmosis caused by Histoplasma capsulatum in a young adult Haitian, and review of the digestive disorders as reported in the previous medical papers. In the present case, the first localization detected was a granulomatous hepatitis which lead to the disclosure of an ulcerous entercolitis. Tuberculosis and Crohn disease were first suspected, but their treatment induced a worse turn of the patient's condition and compelled to a laparotomy, which shown ulcerous entercolitis with associated lymph-nodes. Per operative pathological examination gave evidence of Histoplasma capsulatum yeasts. Treatment, first with miconazole and later on with amphotericin B could not prevent the death of the patient affected by a deficiency of cell mediated immunity. Disseminated histoplasmosis is rare: 1 out of 5,000 cases of American histoplasmosis-digestive disorders are generally detected by surgery or post-mortem examination. They occur in 20 p. 100 of the cases envolving the whole digestive tract from mouth to anus, giving mucous ulcerations, difficult to detect by X ray. Endoscopic control with biopsies has therefore a great value. In Histoplasma duboisii, histoplasmosis digestive disorders are very unusual and localized to intestine. They may be detected by surgery, or by endoscopies. In the reported case, in spite of the geographical origin of the patient, the diagnosis of American histoplasmosis was not retained because of the negativity of the immunological tests and of the biopsies performed before surgery. An afterward checking of these biopsy specimens gave evidence of a few yeasts. Special dyeing technique may have made the diagnosis somewhat earlier; this is important because new non toxic imidazole drugs seem to be active against these yeasts.

Medical records from 39 cats with hepatic disease, examined at the Veterinary Medical Teaching Hospital, University of Florida, between 1987 and 1992 were retrospectively evaluated for alterations in red blood cell (RBC) morphology. Diagnoses included: hepatic lipidosis, neoplasia, cholangiohepatitis, hepatitis/hepatopathy, systemic histoplasmosis, and portocaval shunt. A total of 56 laboratory data sets were studied which included complete blood counts and serum chemistry results. Stained blood smears were evaluated from 51 of the data sets. Twenty-two cats (56%) were determined to have poikilocytosis on the basis of blood smear evaluation. Eleven (28%) cats had moderate to marked poikilocytosis (2+ to 4+). Acanthocytes accounted for 62.6 -/+ 22.1% of morphologically abnormal RBC and were observed in blood smears from 100% of cats with poikilocytosis. Elliptocytes (ovalocytes) comprised 19.5 -/+ 15.8% of poikilocytes and were found in smears from 82% of cats with poikilocytosis. Keratocytes (7.0 -/+ 6.8%), schistocytes (3.6 -/+ 4.4%), and blister cells (2.6 -/+ 6.4%) were present in lower numbers and in fewer cats. Serum total cholesterol values were significantly greater (p < 0.05) in cats with moderate to marked alterations in RBC morphology. Cats with hepatic lipidosis were significantly (p < 0.04) more likely to have poikilocytosis than cats with other types of hepatic disease.

Histoplasmosis is an endemic mycosis in the Ohio and Mississippi River valleys and can cause disseminated infection in immunocompromised hosts. Disseminated histoplasmosis is often respiratory in nature and most cases in transplant patients occur within 2 years post-transplantation. A 32-year-old male on mycophenolate and tacrolimus who underwent an orthotopic liver transplantation 10 years prior presented with generalized body aches, fevers, mild congestion, dysuria and elevated transaminases. Liver biopsy revealed epithelioid granulomas with narrow-based budding yeast, suggesting histoplasma. Liver involvement in disseminated histoplasmosis is well characterized however the disease is usually pulmonary in origin. Only three other case reports describe isolated granulomatous hepatitis, and this is the first to our knowledge to occur in a liver transplant allograft. A high index of suspicion is essential for diagnosis and prompt treatment of histoplasmosis in transplant patients considering their immunocompromised state.
