Fatal necrotizing Candida esophagitis in a patient with leukocytoclastic cutaneous vasculitis and ankylosing spondylitis

Esophageal infection by Candida spp. is a common opportunistic entity in immunocompromised hosts; however, systemic fungal dissemination due to perforation or transmural necrosis, also known as necrotizing Candida esophagitis (NCE), is rare. We report the case of a 61-year-old male patient with diagnosed ankylosing spondylitis, severe arteriosclerosis, and vasculitis under immunosuppressive therapy who presented NCE with fungal and bacterial septicemia diagnosed at autopsy. Necrotizing esophagitis is a rare manifestation of Candida infection, which may be a final complication in severely ill patients. Unfortunately, it may be underdiagnosed, and we call attention to this devastating complication in patients with leukocytoclastic cutaneous vasculitis and ankylosing spondylitis.

Pulmonary histoplasmoma: a disguised malady

Histoplasmosis is a mycosis caused by the dimorphic fungus, Histoplasma capsulatum, which is transmitted via dust and aerosols. Lung involvement is the most common, with a varied clinical presentation. Although it is not the only source of infection, H. capsulatum is frequently found in bat guano, which is the reason why it is highly prevalent among caving practitioners. The solitary histoplasmoma of the lung is an unusual and chronic manifestation of this entity, which mimics, or at least is frequently misconstrued, as a malignancy. Almost invariably, the diagnosis of this type of histoplasmosis presentation is achieved after lung biopsy. The authors present the case of a young woman who sought medical care because of chest pain. The diagnostic work-up revealed the presence of a pulmonary nodule. She was submitted to a thoracotomy and wedge pulmonary resection. The histologic analysis rendered the diagnosis of histoplasmoma. Thisreport aims to call attention to this diagnosis as the differential diagnosis of a pulmonary nodule.

Amyloidosis: an unusual cause of portal hypertension

Amyloidosis comprises a group of diseases that occurs in five to nine cases per million patients per year worldwide irrespective of its classification. Although the hepatic involvement in primary amyloidosis is frequent, the clinical manifestations of liver amyloidosis are mild or even absent. The authors report the case of an aged man who complained of diffuse abdominal pain and marked weight loss and presented clinical signs of hepatopathy. Clinical workup revealed portal hypertension with ascites, hemorrhoids, and esophageal varices. The laboratory tests showed the cholestatic pattern of liver enzymes, hyperbilirubinemia, renal insufficiency and massive proteinuria accompanied by the presence of serum pike of monoclonal lambda light chain protein. The outcome was unfavorable, and the patient died. The autopsy findings revealed the diagnosis of amyloidosis predominantly involving the liver and kidneys. The bone marrow examination demonstrated the deposition of amyloid material associated with clonal plasma cells infiltration. The authors call attention to portal hypertension as a rare manifestation of primary amyloidosis. Meanwhile, this diagnosis should be taken into account whenever the hepatopathy is accompanied by laboratory abnormalities consistent with hepatic space-occupying lesions concomitantly with other organs involvement. In the case reported herein, kidney involvement was also present with renal failure, massive proteinuria with monoclonal serum gammopathy, what reinforced the diagnostic possibility of primary amyloidosis
