Pulmonary mucormycosis is a relatively uncommon but an important opportunistic fungal infection in immunocompromised patients. It may be acquired by inhalation of spores into the lungs. The pathogenic hallmark of mucormycosis is vascular invasion resulting in thrombosis and tissue infarction/necrosis. The diagnosis can be difficult since presentation does not differ from other forms of pneumonia. Risk factors include neutropenia, haematologic malignancies, uncontrolled diabetes mellitus, skin burns and deferoxamine therapy in dialysis patients...

Pleuropulmonary manifestations of systemic lupus erythematosus (SLE) have been reported to be of variable prevalence, depending on the diagnostic methods used. The objective of this study was to determine the anatomopathological prevalence and the nature of lung involvement associated with SLE and to define if there were differences in the grade and type of pulmonary involvement in patients who had died at different time periods, before or after 1996. Complete autopsy studies of 90 patients with SLE diagnosis carried out between 1958 and 2006 and their clinical records were studied...

Mucormycosis is an infection caused by a class Zygomycetes fungi. The rhinocerebral and pulmonary are the most common clinical presentations. Renal mucormycosis is a very rare form. To date, only 25 cases have been reported in the literature. We describe the case of a patient with leukemia who developed isolated renal mucormycosis and review the literature.

We show the records about diagnosed mycoses in a hospital in Mexico City in two periods of time: from 1967 to 1977 and from 1993 to 1997. In the former 15,429 patients were studied and in the latter, 5,998. Striking differences among frequency, etiological agents and clinical outcome, were observed. The most frequent infections in both lapses were the superficial ones, however the most recent scores showed a notorious increase in opportunistic infections. We diagnosed only one histoplasmosis case during the period from 1993 to 1997...

Hospital San Juan de Dios and Sor María Ludovica in La Plata, between 1980 and 1997. Mucormicosis is a frequently fatal, opportunistic fungal infection, that affects immunocompromised patients. The risk factors include diabetes mellitus, leukemia, lymphoma, burns, etc. We present three cases of cutaneous mucormicosis in children 3, 10 and 11 years old, who had been sent to the hospital due to compound fractures in a car crash; one case of pulmonary mucormicosis in an adult 28 years old with prolonged corticotherapy and rhinocerebral mucormicosis in a patient 38 years old with a diagnosis of acute lymphoid leukemia...

The possibility of contact endoscopy in the nasal mucosa, using a contact microlaryngoscope is examined. With contact endoscopy it has been possible to visualize in vivo and in situ (60x, 150x) the superficial cell layers of the nasal epithelium, previously stained with methylene blue. Normal mucosa and cases with pathology (chronic rhinitis, nasal polyposis, inverted papilloma, mucormicosis and carcinoma) were assessed with contact endoscopy (50 patients). Squamous epithelium, ciliated epithelium, glandular ostia, mucus secretions, microvascular networks, inflammatory cell infiltrates, tissue inclusions, nuclear abnormalities, and fungal hyphae have been made visible...

Rhinocerebral mucormycosis is a severe, often fulminant, infection. However, there is evidence of more benign mucormycosis limited to paranasal sinuses and the orbit. We report a case of paranasal mucormycosis treated successfully with endoscopic nasosinusal surgery and amphotericin B.
