BACKGROUND In HIV-1-positive patients there have been no prospective studies that show an increase in cutaneous neoplasms. OBJECTIVE We observed HIV-1-positive patients to determine whether or not there was an increased incidence of cutaneous malignancies. METHODS A total of 724 HIV-1-positive patients were examined during a 36-month period for the(More)
Although cytomegalovirus has previously been reported in cutaneous lesions of patients infected with the human immunodeficiency virus, these reports are not common despite the prevalence of this infection and the significant pathologic characteristics that it induces in HIV disease. Rare reports of possible epidermal involvement by cytomegalovirus have(More)
Microsporidia are obligate intracellular protozoal parasites that infect a variety of cell types in a broad range of invertebrates and vertebrates. They have recently come to medical attention due to the increased frequency with which members of two microsporidian genera, Enterocytozoon and Encephalitozoon, are being diagnosed in patients with the acquired(More)
We studied renal tissues from 203 patients with acquired immunodeficiency syndrome (AIDS). Of the 203 patients, 20 showed light-microscopic changes characteristic of AIDS-associated nephropathy (AAN). Fifteen of the 20 (group A) were examined by immunohistochemistry using Mycoplasma fermentans (incognitus strain)-specific monoclonal antibodies and electron(More)

OBJECTIVE These cases were reviewed to determine whether there was a specific pattern of response to(More)
Bacillary angiomatosis (BA) is a pathological process characterized by prominent vascular proliferation secondary to organisms of the genus Rochalimaea.
