RESUMEN
RATIONALE: Light-chain deposition disease (LCDD) is a rare condition characterized by the abnormal deposition of monoclonal light chains (LCs) in multiple organs, leading to progressive organ dysfunction. Herein, we report a case of plasma cell myeloma initially diagnosed as LCDD on liver biopsy performed for prominent cholestatic hepatitis. PATIENT CONCERNS: A 55-year-old Korean man complained of dyspepsia as the main symptom. On abdominal computed tomography performed at another hospital, the liver showed mildly decreased and heterogeneous attenuation with mild periportal edema. Preliminary liver function tests revealed abnormal results. The patient was treated for an unspecified liver disease; however, his jaundice gradually worsened, prompting him to visit our outpatient hepatology clinic for further evaluation. Magnetic resonance cholangiography revealed liver cirrhosis with severe hepatomegaly of unknown cause. A liver biopsy was performed for the diagnosis. Hematoxylin and eosin staining revealed diffuse extracellular amorphous deposits in perisinusoidal spaces with compressed hepatocytes. The deposits, which morphologically resembled amyloids, were not stained by Congo red but stained strongly positive for kappa LCs and weakly positive for lambda LCs. DIAGNOSES: Therefore, the patient was diagnosed with LCDD. Further systemic examination revealed a plasma cell myeloma. INTERVENTIONS: Fluorescence in situ hybridization, cytogenetics, and next-generation sequencing tested in bone marrow showed no abnormalities. The patient initially received bortezomib/lenalidomide/dexamethasone as the treatment regimen for plasma cell myeloma. OUTCOMES: However, he died shortly thereafter because of coronavirus disease 2019 complications. LESSONS: This case demonstrates that LCDD may present with sudden cholestatic hepatitis and hepatomegaly, and may be fatal if patients do not receive appropriate and timely treatment because of delayed diagnosis. Liver biopsy is useful for the diagnosis of patients with liver disease of unknown etiology.

BACKGROUND: The association between COVID-19 infection and the development of autoimmune diseases is currently unknown, but there are already reports presenting induction of different autoantibodies by SARS-CoV-2 infection. Kikuchi-Fuimoto disease (KFD) as a form of histiocytic necrotizing lymphadenitis of unknown origin. OBJECTIVE: Here we present a rare case of KFD with heart involvement after COVID-19 infection. To our best knowledge only a few cases of COVID-19-associated KFD were published so far. Based on presented case, we summarize the clinical course of KFD and its association with autoimmune diseases, as well we discuss the potential causes of perimyocarditis in this case. METHODS: We reviewed the literature regarding cases of "Kikuchi-Fujimoto disease (KFD)" and "COVID-19" and then "KFD" and "heart" or "myocarditis" by searching medical journal databases written in English in PubMed and Google Scholar. RESULTS: Only two cases of KFD after COVID infection have been described so far. CONCLUSION: SARS-CoV-2 infection can also be a new, potential causative agent of developing KFD.

A 31-year-old immunocompetent, heterosexual man with no relevant medical history presented with 1 week of jaundice, abdominal pain, cough and headache. Examination revealed scleral icterus, right upper quadrant tenderness and hepatomegaly. Initial investigations revealed hyperbilirubinaemia and elevated transaminases. Serum studies were positive for antinuclear antibodies, antimitochondrial antibodies, and herpes simplex virus IgM. Despite being started on intravenous acyclovir, his bilirubin and transaminase levels continued to rise. He was subsequently tested for syphilis given his maculopapular rash on the soles of his feet and it returned positive. He improved clinically with the initiation of penicillin. In this case, we will discuss the presentation, diagnosis and treatment of syphilitic hepatitis.

ABSTRACT: The 2019 novel coronavirus disease (COVID-19) has spread worldwide, infiltrating, infecting, and devastating communities in all locations of varying demographics. An overwhelming majority of published literature on the pathologic findings associated with COVID-19 is either from living clinical cohorts or from autopsy findings of those who died in a medical care setting, which can confound pure disease pathology. A relatively low initial infection rate paired with a high biosafety level enabled the New Mexico Office of the Medical Investigator to conduct full autopsy examinations on suspected COVID-19-related deaths. Full autopsy examination on the first 20 severe acute respiratory syndrome coronavirus 2-positive decedents revealed that some extent of diffuse alveolar damage in every death due to COVID-19 played some role. The average decedent was middle-aged, male, American Indian, and overweight with comorbidities that included diabetes, ethanolism, and atherosclerotic and/or hypertensive cardiovascular disease. Macroscopic thrombotic events were seen in 35% of cases consisting of pulmonary thromboemboli and coronary artery thrombi. In 2 cases, severe bacterial coinfections were seen in the lungs. Those determined to die with but not of severe acute respiratory syndrome coronavirus 2 infection had unremarkable lung findings.

We report findings on abdominal imaging in critically ill children admitted with MIS-C. On sonography, hepatomegaly, nephromegaly, gallbladder wall edema, ascites, intestinal inflammation and mesenteric lymphadenopathy were seen, while CT showed fluid-filled small bowel loops, mural thickening of the terminal ileum, diffuse lymphadenopathy, and moderate ascites.

Newborn screening (NBS) of cystic fibrosis (CF) is not available currently in Hungary. Pediatricians should be able to recognize the illness based on the symptoms alone. Lack of NBS causes differential diagnostic challenges for physicians and delayed diagnosis of CF. We present a case of a two-year-old girl who was transferred to our hospital as a suspected Covid-19 patient with one week history of fever and coughing in March 2020. As Covid-19 was excluded, the severity of the clinical picture pointed towards an acute exacerbation of an underlying chronic condition. Her symptoms such as tachypnea, wheezing, lung crackles, hepatomegaly and clubbing of the fingers were all consistent with undiagnosed CF. In the end, sweat chloride level and genetic test verified the diagnosis. This case emphasizes the need of NBS in Hungary.

The clinical manifestations of coronavirus disease 2019 (COVID-19) are non-specific and multi-inflammatory. They vary from mild to severe manifestations that can be life-threatening. The association of SARS-CoV-2 infection and pseudoaneurysm formation or rupture of an already existing aneurysm is still unexplored. Several mechanisms may be involved, including the direct destruction to the artery by the viral infection or through the release of the inflammatory cytokines. We are presenting a case of a 13-year-old girl with a ruptured cerebral pseudoaneurysm of the left middle cerebral artery (M2 segment) with severe intracerebral hemorrhage as the earliest manifestation of COVID-19 infection.
