Non-tuberculous mycobacteria (NTM) are one of the predominant microbes observed in immunocompromised patients with structural lung disease. Especially in immunocompromised patients, the treating physician needs to be aware of concurrent lung infections with opportunistic pathogens. In this case report we present a man in his 60s with severe chronic obstructive pulmonary disease (COPD) and bullous emphysema, who was diagnosed with but with persistent clinical deterioration despite relevant treatment for NTM. A subsequent bronchoalveolar lavage (BAL) revealed elevated galactomannan antigen which, when seen in relation to imaging-findings of cavitating opacities with aggravating surrounding consolidation, raised suspicion of concurrent subacute invasive aspergillosis. Antifungal treatment was initiated but due to intolerable side effects was discontinued after only a few weeks. This case highlights the importance of concurrent testing for pulmonary aspergillosis in NTM patients and vice versa before treatment initiation and if the disease and symptoms are progressing despite relevant treatment.

Invasive pulmonary infections are a significant cause of morbidity and mortality in patients with hematological malignancies and hematopoietic stem cell transplantation (HCT) recipients. A delay in identifying a causative agent may result in late initiation of appropriate treatment and adverse clinical outcomes. We examine the diagnostic utility of PCR-based assays in evaluating invasive pulmonary infections from bronchoalveolar lavage (BAL).

Verruca vulgaris is a cutaneous infection predominantly caused by human papillomavirus (HPV) type 1, 2, and 4. In immunocompromised individuals infected with human immunodeficiency virus (HIV) infection, HPV leads to a higher prevalence of infections and also has a greater likelihood of being infected with atypical types such as genital-associated HPV in extragenital sites. This case report describes a 48-year-old male patient who presented with skin-colored verrucous papules on the hands and feet, with no evidence of genital lesions.

Background: Antimicrobial resistance is a global public health emergency. Patients undergoing hematopoietic stem cell transplantation (HCT) are at increased risk for severe infections with multidrug-resistant (MDR) organisms, although more data are needed on the relative burden of MDR Enterobacterales (MDR-E) in immunocompromised populations. In this study, we compare the prevalence of Enterobacterales resistance in cultures from patients undergoing HCT with that of non-HCT patients seeking care at a large healthcare system in North Carolina, USA.

Background: Classic Hodgkin lymphoma (CHL) is an extremely common non-acquired immunodeficiency syndrome (AIDS) defining malignancy and its incidence is rising. CHL is usually present in the lymph node and extranodal involvement is rare. Primary CHL of the gastrointestinal (GI) tract is exceedingly rare.

Necrotizing fasciitis is a potentially life-threatening infection that can lead to rapid muscular and fascial necrosis, often resulting in sepsis. In addition to the rapid disease progression, diagnosing this disease in children can be challenging as they cannot accurately communicate their symptoms. Spontaneous necrotizing fasciitis secondary to Clostridial infection has rarely been described in the literature but occurs in neutropenic patients with significant morbidity and mortality from myonecrosis and gas gangrene.
