In a 70-year-old male patient with untreated diabetes a febrile orbital apex syndrome of rapid onset revealed a rhino-orbito-cerebral zygomycosis. Biopsies of the ethmoidal mucosa showed numerous colonies of the Rhizopus genus. Despite medical treatment (amphotericin B) and surgery (ethmoidectomy), the patient died within one week. Rhino-cerebral zygomycosis is a rare disease which occurs in diabetic and immunocompromised patients.

Eight documented cases of pulmonary zygomycosis were analyzed retrospectively with regard to radiographic and clinical features. Predisposing factors were diabetes mellitus in six cases, lymphoblastic lymphoma in one case, and surgery to correct a tracheoesophageal fistula in one case. Two of the patients with diabetes had also undergone renal transplantation for diabetic nephropathy and were immunosuppressed. The more usual radiographic findings of pulmonary zygomycosis represent a spectrum that comprises a normal chest radiograph, a lung abscess, subacute or chronic pneumonia that often evolves into a lung abscess, and rapidly progressive fatal pneumonia. Awareness of the various presentations of pulmonary zygomycosis is important because early diagnosis and appropriate therapy clearly have been shown to improve the survival rate of these patients. Zygomycosis should be included in the differential diagnosis when patients with diabetes mellitus, patients with leukemia or lymphoma, or immunocompromised patients present with or develop perplexing pulmonary abnormalities.

Aspergillosis, cryptococcosis and zygomycosis (mucormycosis) are overall the most common systemic mycoses but histoplasmosis is particularly endemic in parts of central USA and other areas worldwide. Orofacial lesions caused by systemic mycoses have rarely been reported in the past though they have been recorded particularly in outdoor workers from geographic areas with a high prevalence of infection and occasionally in immunocompromised individuals. Increasing world-wide travel, and the dramatic increase in numbers of immunocompromised persons, especially those with human immunodeficiency virus (HIV) disease, have been responsible for an increase in reports and other studies of orofacial disease in systemic mycoses and new opportunists are now being recognized. Those in Oral Medicine and Pathology must now be aware of the possibility of a systemic mycosis as the cause of chronic oral ulceration, chronic maxillary sinus infection, or bizarre mouth lesions, especially in patients with HIV disease, lymphoproliferative disorders, or diabetes mellitus, or in those who have been in endemic areas. Diagnosis and management should be undertaken in consultation with a physician with appropriate expertise, as pulmonary and other systemic infection may well be present. This paper reviews the eight main systemic mycoses.

Mucormycosis (synonymous with phycomycosis and zygomycosis) is a devastating fungal infection which usually involves patients with diabetes mellitus, often complicated by ketoacidosis, and malignant neoplasms, commonly leukemia and lymphoma. Clinical manifestations include rhinocerebral, pulmonary, disseminated, isolated cerebral, gastrointestinal and cutaneous disease. Common to all forms of mucormycosis is vascular invasion with production of necrotic tissue. The diagnosis is achieved by demonstrating broad, non-septate hyphae with right-angle branching in a tissue biopsy specimen. Successful treatment consists of early diagnosis, intensive systemic antifungal therapy with amphotericin B, aggressive surgical debridement and control of the underlying disease. In our experience with mucormycosis at Huntsville Hospital, the patients were immuno- compromised and the infection was restricted to the lung. Despite use of amphotericin B in all patients, the only one who survived underwent surgical section of infected tissue.

Zygomycosis, an invasive fungal infection, is usually seen in persons with diabetes, particularly in those with diabetic ketoacidosis. The infection most frequently occurs in the rhinocerebral region and rapidly spreads, causing a swift demise. Rarely, the infection is confined to the cutaneous tissues. We describe a 31-year-old man seropositive for human T lymphotropic virus type I who had diabetic ketoacidosis with zygomycosis confined to the right arm. The lesion was presumed initially to be a bacterial infection but did not respond to conventional antimicrobial therapy. The arm lesion was cultured, and Rhizopus arrhizus was isolated. The patient responded well to a combination of amphotericin B and extensive surgical debridements. Our case emphasizes the importance of maintaining a high index of suspicion of cutaneous zygomycotic infections in the impaired host, especially of those in patients with diabetes, who do not respond to initial antimicrobial treatment.

Diabetes mellitus produces serious complications in several major organ systems. The pulmonary complications, although uncommon and not well recognized, may be life-threatening. We describe a 20-year-old patient with diabetic ketoacidosis in whom pulmonary zygomycosis developed. This condition was complicated by stenosis of the left upper lobe bronchus despite successful treatment of the zygomycosis. Bronchial obstruction has become a well-recognized complication of pulmonary zygomycosis. In addition to infections caused by Zygomycetes, mycobacteria, viruses, and bacteria, the pulmonary complications described in patients with diabetes include pulmonary edema, disordered breathing during sleep, and reductions in elastic recoil of the lungs, diffusing capacity of the lungs for carbon monoxide, and bronchomotor tone. Other reported complications are respiratory alkalosis, cardiorespiratory arrest, pneumothorax, pneumomediastinum, plugging of the airways with mucus, and aspiration pneumonia attributable to diabetic gastroparesis.

Zygomycosis of the basal ganglia should be recognized as a syndrome in intravenous drug users associated with a culture-negative cellular CSF, fever, lethargy, and lesions apparent on contrast-enhanced CT scans of the head. The infection is most likely the result of intravenous inoculation of fungal spores. This entity is different from the rhinocerebral zygomycosis seen with diabetes mellitus and other diseases. In the rhinocerebral form, there are external signs of the disease with involvement of the orbit, paranasal sinuses, and palate. In these drug users, infection was directed to areas deep within the brain.

Mucormycosis (or zygomycosis) is an opportunistic fungal infection which usually is seen in patients who are immunosuppressed or who have diabetes. It is uncommon in healthy persons and also is uncommon in Australia. We report a case of a 45-year-old, otherwise-healthy man with an indolent lung infection that was caused by Absidia corymbifera, who was cured by a combination of surgical and medical therapy.

A 15-year-old boy presented with unilateral nasal polyps. Pathological examination showed submucosal granulomas and fungal organisms with occasionally septate hyphae. These organisms were identified by the Centers for Disease Control, Atlanta, as being members of the class of fungi known as Zygomycetes (formerly Phycomycetes). Based on strong morphological and clinical criteria, we believe the causative organism to be Entomophthora coronata. The patient had no evidence of diabetes mellitus or compromised immunity. This patient represents an unusual case of nasal polyps caused by an organism that has rarely been diagnosed in North America.

An alcoholic man with uncontrolled diabetes mellitus had right conjunctivitis, facial numbness, and periorbital edema progressing to bilateral visual loss, and left ptosis in association with a large necrotic palatal ulcer due to zygomycosis. The infection progressed to bilateral retinal vein engorgement; left-sided ophthalmoplegia, fixed dilated pupil, and absent corneal reflex; and right-sided ophthalmoplegia, ptosis, and facial nerve paralysis. Work-up revealed disease of both ethmoid sinuses and the right maxillary sinus, with bilateral thromboses of the cavernous sinuses. An aggressive combined therapeutic attack (three Caldwell-Luc procedures, exploration of orbit walls, control of diabetes, systemic and local amphotericin therapy) led to survival with a three-year follow-up thus far.
