Congenital neutropenia (CoN) is a heterogeneous group of inborn errors of immunity (IEI) characterized by recurrent infections and early onset of neutropenia (NP). This study aimed to investigate the demographic and clinical data of children with CoN and idiopathic neutropenia (IN) in Morocco. We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital.

Background: Idiopathic CD4+ T lymphocytopenia is a rare immune dysfunction disease that is usually found after opportunistic infections. Mycobacterium abscessus is a rapidly growing mycobacterium that can cause pulmonary infections, lymphadenitis, skin and soft tissue infections, disseminated infections, among others, as a conditional pathogenic bacterium.
Case Presentation: We present the case of a 43-year-old Chinese woman who developed disseminated Mycobacterium abscessus infection due to idiopathic CD4+ T lymphocytopenia.

Common variable immunodeficiency (CVID) is one of the most common groups of human inborn errors of immunity. In addition to infections resulting from insufficient levels of immunoglobulins and antibodies, a significant proportion of patients develop autoimmune cytopenias, especially immune thrombocytopenia, hemolytic anemia, or neutropenia. They may be the initial manifestation of CVID in a patient who has not had significant infections, and similar episodes may recur at intervals over time.

Considering its rarity, the clinical characteristics of Sweet syndrome are still unclear. We aimed to analyse clinicopathological characteristics, treatment, and outcomes of patients with Sweet syndrome according to concurrent malignancy.

Disseminated histoplasmosis is a rare yet serious fungal infection that primarily affects individuals with compromised immune systems. While it is widely known for its endemicity in the Midwest region of the USA, recent studies have indicated a noteworthy increase in sporadic cases, suggesting a widening of the endemic region for the pathology. This report describes a case of disseminated histoplasmosis in a 39-year-old female with a history of lupus, hypertension, anxiety, asthma, idiopathic edema, and fibromyalgia from a nonendemic region, who presented with cyclic fevers of unknown origin, peripheral edema, and oral sores.
