AI Article Synopsis
- Palisaded neutrophilic granulomatous dermatitis is a rare skin condition in children linked to autoimmune diseases, with its exact cause not fully understood but potentially involving immune complex deposition.
- An 11-year-old girl with polymorphic skin lesions and polyarthralgia was diagnosed with systemic lupus erythematosus and lupus nephritis, necessitating various treatments including steroids and immunosuppressants.
- Recognizing this skin condition is crucial as it may be an early indicator of systemic lupus erythematosus in young patients.
Article Abstract
Background: Palisaded neutrophilic granulomatous dermatitis is a rare cutaneous manifestation in children associated with autoimmune pathologies. The exact pathogenesis of this disease is still unknown. However, it has been suggested that the deposition of immune complexes could initiate this pathology.
Case Report: We describe the case of an 11-year-old female patient who presented with polymorphic lesions in extremities associated with polyarthralgia. She was diagnosed with systemic lupus erythematosus and lupus nephritis. Because of the skin lesions, histopathological and immunohistochemical skin studies (CD68, CD163, myeloperoxidase) were performed, which resulted in palisaded neutrophilic granulomatous dermatitis. Due to renal involvement, treatment was administered with methylprednisolone pulses, hydroxychloroquine, mycophenolate mofetil, antihypertensives, and nonsteroidal anti-inflammatory drugs. The clinical response was favorable during follow-up.
Conclusions: Palisaded neutrophilic granulomatous dermatitis associated with systemic lupus erythematosus is unusual. Therefore, its recognition is important, as it may appear as the initial manifestation of this autoimmune disease.

Tattooing has become a popular global trend in industrialised countries, with the highest prevalence rates of up to 30-40 % in the adult population younger than 40 years. Common tattoo inks may contain heavy metals, polycyclic aromatic hydrocarbons, and primary aromatic amines, toxic if exceeding permissible limits. It is estimated that about 14.

Granulomatous mastitis is a chronic inflammation of the breast, mostly of unknown etiology. The treatment would be definitive if the causative organism were isolated. It is characterized histologically by granulomas, formed mostly by polymorph nuclear neutrophils and central necrosis.

Cystic neutrophilic granulomatous mastitis (CNGM) is a rare type of granulomatous lobular mastitis (GLM) with a distinct histologic pattern characterized on histopathology by clear lipid vacuoles lined by peripheral neutrophils ("suppurative lipogranulomas"), often containing gram-positive bacilli and strongly associated with Corynebacterial infection (in particular, Corynebacterium kroppenstedtii). Cystic neutrophilic granulomatous mastitis has a distinct histopathologic appearance, but the imaging appearance is less well described and has been limited to case reports and small case series published primarily in pathology literature. Mammographic findings of CNGM include focal asymmetry, skin thickening, and irregular or oval masses.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are autoimmune inflammatory small-vessel disorders with potentially life-threatening organ manifestations. Recent disease definitions and classification criteria allow distinction between granulomatosis with polyangiitis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA), and non-granulomatous microscopic polyangiitis (MPA). The discovery of ANCA-autoantibodies directed against proteolytic enzymes of neutrophil granules-has enabled earlier diagnosis of AAV and paved the way to stage-adapted treatments.

Introduction: Tuberculosis remains the leading cause of death from infectious diseases among adults worldwide. To date, an overarching review of the immune response to in humans has not been fully elucidated, with innate immunity remaining poorly understood due to historic focus on adaptive immunity. Specifically, there is a major gap concerning the contribution of the immune system to overall bacterial clearance, particularly residual bacteria.
