Objectives: Chronic granulomatous disease is a rare phagocyte disorder characterized by an increased susceptibility to infections and inflammatory complications. We describe two patients with chronic granulomatous disease (CGD) complicated by macrophage activation syndrome (MAS) (secondary hemophagocytic lymphohistiocytosis) treated with intravenous immunoglobulin (IVIG).
Methods: A report of two cases of CGD complicated by MAS who were successfully treated with IVIG was made, and a comparison was made with ten other cases reported in the literature.
Results: MAS is a severe potentially fatal complication of CGD. Most cases are associated with Burkholderia cepacia and leishmaniasis infection. The treatment of these patients varies between centers, and one example is the use of the HLH-2004 protocol. IVIG could be an effective first line option for this complication in CGD patients.
Conclusions: The exaggerated inflammatory response characteristic of CGD patients could play a role in the development of this complication. IVIG appears to be a safe and effective first line treatment in these patients.

Although idiopathic granulomatous mastitis (GM) of the breast is a benign condition, it can be locally aggressive and frequently chronic, causing significant pain and distress to the patient. Treatment often involves multiple disciplines including general practice, breast surgery/physicians, rheumatology and/or immunology. Traditional options for treatment include observation, oral steroids, methotrexate and/or surgery, all with variable outcomes.

Objective: Pulmonary involvement in chronic nonbacterial osteomyelitis (CNO) is rare. Limited awareness results in diagnostic challenges, especially because malignancy or infection needs to be considered.
Methods: Based on a survey shared among centers participating in the Kerndokumentation Deutsches Rheumaforschungszentrum (Germany), this study investigated clinical and imaging presentations, demographic features, treatment response and outcomes of pulmonary involvement in CNO (pCNO).

Chronic inflammatory diseases show significant heterogeneity in their phenotypes, with diverse immune cells and mediators interacting in response to various stimuli. This review proposes the concept of the 'inflammazone' framework - which maps the distribution of immune components driving disease pathogenesis - using sarcoidosis and psoriasis as examples. Sarcoidosis features granulomatous inflammation with macrophages and CD4 T cells, which can spread to lymph nodes and other organs.

Basidiobolomycosis, a rare fungal infection seen in immunocompetent patients, is a chronic granulomatous infection affecting the skin and subcutaneous tissue. It is caused by the fungus . Gastrointestinal basidiobolomycosis usually has non-specific clinical manifestations, and its diagnosis requires a high index of suspicion.

The diagnosis and management of complex neurological conditions such as New-Onset Refractory Status Epilepticus (NORSE) and central nervous system (CNS) infections caused by non-tuberculous mycobacteria (NTM) pose substantial difficulties in intensive care units (ICUs). This article combines a case report and a literature review that explores the diagnostic dilemmas and therapeutic strategies for these critical conditions. We report the case of an 83-year-old female with chronic granulomatous meningitis secondary to NTM, presenting a challenging diagnostic and complex management complexity typical of such a rare disease through a period time of five years.
