Ulcerative colitisCrohn’s diseaseUlcerative colitis status posttotal colectomy 20 y prior to admission.Inflammatory bowel disease

Treatment for IBDChronic corticosteroidsAzathioprine and infliximabCorticosteroids, mesalazineInfliximab infusions, oral 6 mercaptopurine (6 MP), and oral and intravenous corticosteroids Methotrexate, corticosteroidsIntravenous corticosteroids, oral 6-MP, and oral sulfasalazine

Initial symptomsFever, cough, and chest pain. Nonresolving pneumoniaPeritonitis followed by intestinal perforationNasal congestion, fullness, headache, and feversExacerbation of underlying condition.

In-hospital course: fever, septic shock, trans esophageal echocardiogram: 6 × 1.8 cm right atrial mass
Severe abdominal pain. 

CT scan abdomen and pelvis: recurrent
pneumoperitoneum
Nonhealing periosteal lesion resembling pyoderma gangrenosumHigh fever, nausea, vomiting, bloody diarrhea, and pain in right flank

Presentation form 
of mucormycosis
Pulmonary 

Bronchoscopy: soft tissue mass obstructing the bronchus intermedius suggestive of fungal pneumonia
Gastrointestinal SinusEndocarditis; suspected hematogenous spread to lungs with multiple nodal lesions with central necrosis on chest computed tomography (CT)Gastric perforationCutaneousDisseminated
(colon and right kidney)

Diagnosis of mucormycosisAntemortem
biopsy of bronchial mass: ulcerated bronchial wall with ischemic necrosis, fibrinopurulent exudates, and hyphae suggestive of mucormycosis
Postmortem: colon tissue: hyphae suggestive of Mucorales, cultures positive for Rhizopus microsporus
  
Peritoneal fluid: microscopic exam: broad irregular hyphae, culture: Rhizopus microsporus
Antemortem: sinus
biopsy: hyphae suggestive of Mucorales
Antemortem: histopathology of atrial endocardial vegetation showed mycotic hyphae.

Microbiologic cultures of atrial appendage positive for Mucor spp.
Antemortem: abdominal wall: histopathology: many broad based nonseptate hyphae admixed with necrotic tissue.Antemortem:
cutaneous
biopsy of new periosteal ulcer: hyphae suggestive of Rhizopus spp. on calcofluor white test.

Culture of periosteal ulcer grew Rhizopus spp.
Antemortem:
right kidney: histopathology: large areas of necrosis. Blood vessel walls invaded by hyphae suggestive of Mucorales.
  
Culture of right kidney positive for Absidia corymbifera

TreatmentPneumonectomy
Amphotericin B, caspofungin
VoriconazoleSurgical debridement and extensive facial tissue resection.

Amphotericin B for 30 days, 6 m course of posaconazole.
Excision of intracardiac mass. 

Liposomal amphotericin B 5 mg/kg.
Surgical debridement, cholecystectomy.

Liposomal amphotericin B (abelcet) 350 mg IV daily
Surgery not done due to medical complications. 

Liposomal amphotericin B (abelcet).
Followed by
oral itraconazole for 3 months.
Elective right nephrectomy, total colectomy.

Amphotericin B (0.7 mg/kg/d)

Outcome Worsening of infection while on antifungals with spread to left upper lobe lung and pericardium.
