Sarcoidosis and lymphoma share immunopathological characteristics that suggest a complex, interconnected relationship. This article examines the multi-faceted mechanisms linking sarcoidosis to lymphoma, a phenomenon called sarcoidosis-lymphoma syndrome (SLS). SLS is hard to diagnose, requiring distinct criteria and imaging to differentiate overlapping features and histological differences.

The most common site for a pilonidal sinus is the sacrococcygeal region, typically affecting hirsute males. Hair entrapment beneath the skin triggers a granulomatous reaction, leading to the formation of a sinus tract. Here, we present a rare case of concurrent pilonidal abscess in both the nape of the neck and the natal cleft.

Introduction: Programmed death-1 (PD-1) is a negative regulator of immune responses. Upon deletion of PD-1 in mice, symptoms of autoimmunity developed only after they got old. In a model experiment in cancer immunotherapy, PD-1 was shown to prevent cytotoxic T lymphocytes from attacking cancer cells that expressed neoantigens derived from genome mutations.

Chronic granulomatous disease is the inborn error of immunity with the highest frequency of invasive aspergillosis. In this context, invasive aspergillosis is frequent in adolescence, with rare cases before one year of age. We present a case of chronic granulomatous disease and invasive aspergillosis in a four-month-old infant.

Interferon-γ (IFN-γ) is a key mediator in antitumor immunity and immunotherapy responses, yet its clinical applications remain restricted to chronic granulomatous disease and malignant osteopetrosis. IFN-γ effectiveness as a standalone treatment has shown limited success in clinical trials and its potential for synergistic effects when combined with immunotherapies is under clinical exploration. A particularly compelling combination is that of IFN-γ with Toll-like receptor (TLR) agonists that holds significant promise for cancer treatment.
