Aseptic abscesses syndrome K50.-

Systemic disease of unclear etiology associated with inflammatory bowel disease (e.g., Crohn's disease), intra-abdominal aseptic abscesses, fever, abdominal pain, and leukocytosis.

In a larger collective, the mean age in patients with "aseptic abscess syndrome" was 29 years (SD = 14).

Inflammatory bowel disease (IBD) may precede abscess formation, occur concurrently with it, or manifest later. The main clinical manifestations of AA are fever (90%), abdominal pain (67%), weight loss (50%). The abscess formations involve the spleen in > 90% (Fillman H et al 2020). They can occur unifocally but also multifocally, with additional involvement of the abdominal lymph nodes in about 50% of patients, the liver in about 40%, the lungs in 17%, the pancreas in 7%, and the brain in 7%.

Dermatologic:

• About 20% of patients had neutrophilic dermatosis (20%).
• 10% suffered from recurrent polychondritis.
• An association with Sweet syndrome (Sutton E et al. 2018) and systemic lupus erythematosus (Andonopoulos AP et al. 1986) was occasionally reported.

Other symptoms: monoclonal gammopathy of undetermined significance(MGUS).

Neutrophilia; detection of antineutrophil cytoplasmic autoantibodies with perinuclear, cytoplasmic, or atypical pattern (negative for antiproteinase 3 and negative for antimyeloperoxidase.
