Subcutaneous mucormycosis caused by Mucor hiemalis Wehmer f. luteus (Linnemann) Schipper 1973.

The authors report a case of subcutaneous mucormycosis in a diabetic patient with verrucous lesions in the fourth finger of the right hand. Initially diagnosed as a fixed cutaneous sporotrichosis case, success was obtained with the use of potassium iodide with healing of the lesion in a period of nearly 5 months. At present the patient remains under clinical observation with no treatment or relapse.

Cerebral mucormycosis in diabetic mice after intrasinus challenge.

Rhinocerebral involvement is the most common form of mucormycosis in uncontrolled diabetic patients. Streptozotocin-induced diabetic and normal mice were challenged by intrasinus inoculation of Rhizopus oryzae to determine their susceptibility to infection by this route. Ninety percent of diabetic mice and no normal mice died after inoculation with 10(6) spores. Intrasinus inoculations caused minimal direct trauma and low levels of brain inocula, but progressive cerebral infections were induced in diabetic mice.

Rhino-orbitocerebral mucormycosis caused by Apophysomyces elegans.

Rhino-orbitocerebral mucormycosis (ROCM) caused by more common zygomycetes (e.g., Mucor) is known to cause rapidly fatal infections in immunocompromised patients. Apophysomyces elegans is an emerging zygomycete that has been reported to cause invasive cutaneous and rhino-orbitocerebral infections in immunocompetent individuals. Limited data exist describing the syndrome of ROCM caused by A. elegans. We describe a recent case and performed a comprehensive literature review to delineate the clinical characteristics of ROCM caused by A. elegans. Our case is a 50-year-old man with diabetes mellitus who presented with facial pain and right eye proptosis. Endoscopic sinus sampling revealed A. elegans. He was treated with liposomal amphotericin B and multiple debridements, with no disease on 1.5-year follow-up examination. Seven cases were identified on literature review, including the present case. Most patients (86%) were male, with a mean age of 40 years. Most patients (71%) did not have predisposing medical conditions. Three patients had predisposing head trauma. All presented with facial and/or periorbital pain. All had magnetic resonance imaging or computed tomography of the head showing intraorbital and/or sinus inflammation. Diagnosis was confirmed by histopathology and deep tissue culture in all cases. All patients required eye exenteration and extensive surgical debridement, in addition to intravenous amphotericin B. Six of the seven patients (86%) recovered. ROCM caused by A. elegans is rarely reported in the literature. Most such infections occurred in immunocompetent patients, often after facial trauma. Survival in ROCM caused by A. elegans is favorable in reported cases, with prompt surgical debridement and antifungal therapy.

Orbitofacial mucormycosis with unusual pathological features.

A 52-year-old man with mild diabetes and acute stem cell leukaemia developed an orbitofacial mucormycosis. Cultures showed the fungus to be Rhizopus oryzae. Vigorous treatment with amphotericin B and other bactericidal and bacteriostatic antibiotics for a concurrent sepsis failed to suppress the infections, and the patient died. On post-mortem examination characteristic haematoxylin-staining, broad, aseptate fungal hyphae were found in the right eye, orbit, and lung. A striking and unusual feature of this case is the presence of brightly birefringent crystals within the severely degenerated eye. These were found by histochemical staining and x-ray diffraction studies to be calcium salts of fatty acids, apparently liberated from necrotic adipose tissue of the orbit.

Fatal fulminant myocarditis caused by disseminated mucormycosis.

Acute fulminant myocarditis is a critical clinical condition with sudden onset of severe congestive heart failure followed by severe haemodynamic deterioration. Instituting early left ventricular support may improve outcome and result in better long term survival. The case of an immunocompromised patient who developed acute fulminant myocarditis in the setting of disseminated mucormycosis is presented.

A case of cerebral mucormycosis diagnosed in life. with eventual recovery.

A case of mucormycosis localized in the brain is reported in a subject aged 18 years who was not suffering from diabetes. As the patient displayed symptoms of cerebral compression he was operated upon and a cystic formation was excised. Microscopic examination disclosed the presence of hyphae, displaying the characteristics of mucor, in chronic granulation tissue. The mycelia had a tendency to develop in the vessels and to invade them, and a structure very similar to a sporangium could be observed. Some of the mycelia had undergone dystrophic calcification.The patient has been kept under medical supervision for two and a half years since the operation and appears to have completely recovered.

A rare presentation of zygomycosis (mucormycosis) and review of the literature.

Zygomycosis (mucormycosis) is a rare fungal infection seen most often in association with prolonged neutropenia. Intestinal zygomycosis is extremely rare and difficult to diagnose, but it is important not to miss, because early medical and surgical treatment can improve survival. This report describes a 56 year old woman who developed this infection while receiving chemotherapy for acute lymphoblastic leukaemia. Medical and surgical measures proved unsuccessful because there was a delay in diagnosis and institution of appropriate treatment.

Presentation and outcome of rhino-orbital-cerebral mucormycosis in patients with diabetes.

AIM: To report presentation and outcome of rhino-orbital-cerebral mucormycosis (ROCM) exclusively in patients with diabetes mellitus. METHODS: Retrospective, non-comparative, interventional analysis of the medical records of 35 patients with ROCM among 22 316 patients with diabetes seen over the last 12 years. RESULTS: A cohort of 23 men and 12 women with a mean (SD) age of 47.3 (14.4) years (range 18-70 years) was studied. Five patients had type 1 diabetes mellitus, 29 had type 2 diabetes mellitus, and one had secondary diabetes. Nine patients had ROCM as the first clinical manifestation of diabetes. The mean (SD) blood glucose at presentation was 20.6 (8.3) mmol/l (range 10.0 to 53.3 mmol/l) and 17 patients had ketosis/ketoacidosis. Ophthalmic symptoms and signs were pronounced: external ophthalmoplegia (89%), proptosis (83%), visual loss (80%), chemosis (74%), and eye lid gangrene (14%). Non-ophthalmic manifestations included sinusitis (100%), nasal discharge/ulceration (74%), infranuclear VI nerve palsy (46%), palatal necrosis (29%), cerebral lobe involvement (20%), and hemiparesis (17%). Computed tomography/magnetic resonance imaging showed involvement of paranasal sinuses in all patients with ethmoid (86%) and maxillary (80%) sinuses being most frequently involved. Orbital involvement was observed in 80% of patients with cavernous sinus thrombosis in 11%, and internal carotid occlusion and hydrocephalus in 3% each. All were treated with amphotericin B (3-3.5 g) and 26 (74%) patients underwent appropriate surgery. Twenty one patients (68%) survived with a mean (SD) follow up of 39.6 (34.1) months (range 10 months to 11 years). Factors related to poor survival included delay in diagnosis and treatment (p<0.05), facial and/or eye lid gangrene (p<0.05), hemiplegia (p<0.05), cerebral invasion by mucorales (p<0.05), and treatment with amphotericin B alone (p<0.05). CONCLUSIONS: In patients with diabetes and ROCM, ROCM was the presenting manifestation in one fourth of the patients. Ophthalmic and extensive cerebral involvement predominated in the clinical picture. Delay in treatment due to late presentation and associated complications were major determinants of the survival outcome in these patients.

Pneumonectomy in pulmonary mucormycosis complicating Behçet's disease.

A 37 year old man with Behçet's disease who was maintained on prolonged corticosteroid therapy, developed diabetic ketoacidosis and pneumonia. Secondary infection with mucor intervened with abscess formation cured by pneumonectomy. The association of Behçet's disease and mucormycosis has not been previously reported, although diabetes mellitus was almost certainly the predisposing cause. Surgical treatment offers the best chance of survival in similar cases.

Systemic aspergillosis and mucormycosis in 23 cats.

The clinical and pathological features of 23 cats with systemic opportunistic mycosis--aspergillosis and mucormycosis--are described. The diagnoses were made post mortem by histology. The history and characteristics of the pathological lesions of the 29 cases of feline mycosis described in the literature are compared with this series. It appears that the incidence of such mycoses is increasing.

Rhizomucor pusillus mucormycosis combined with chlamydiosis in an African grey parrot (Psittacus erithacus erithacus).

This paper describes a case of mucormycosis combined with chlamydiosis in an African grey parrot (Psittacus erithacus erithacus). The clinical signs included diarrhoea, an unsteady gait and a twisted neck. Smears of the spleen, liver and contents of the cloaca stained strongly positive for Chlamydia species. Histologically, hyphae typical of Zygomycetes were observed invading through the walls of blood vessels of the spleen. Rhizomucor pusillus was isolated as a pure culture from the intestines, lungs and liver.
