Sweet's Syndrome (SS); aka Acute Febrile Neutrophilic Dermatosis Neutrophilic Dermatoses Unknown at this time. More common in carriers of HLA-B54. Unknown Affects all races. Rare. One study found the incidence to be 3 per 10,000 amongst new dermatologic patients in Iran. [99] Fevers, often for many days-weeks. Fever may preclude or happen at the onset of other SS symptoms. [97] 1/3 to 2/3 of patients have recurrent Sweets symptoms. Other cases involve a single episode of symptoms in their lifetime. Three forms: Classical/idiopathic SS, drug-induced (DISS), or malignancy-associated Sweet's syndrome (MASS). [97] Adulthood, more frequently in middle-aged women, but also in men. It rarely presents in infants or children. [96] Sweet's presents in response to some trigger, such as infection, inflammation (IBD/Crohns/UC), autoimmune diseases, vaccinations, cancers, or certain medications. [96] Cutaneous pathergy. Multiple painful and tender skin lesions varying from papules and vesicles to wide, thick, swollen plaques. The most common areas for the rash is on the neck, face, upper chest, back and limbs. Some have sores only in areas that are exposed to the sun. [96] Lesions can be annular (ringed), pseudovesicular, and may look like atypical pyoderma gangrenosum. [96] Apthous, or mucosal ulcers (even ocular ulcers at times). [96] Some have erythema nodosum. [97] Skin biopsy: Neutrophillic inflammation and leukocytoclasia without vasculitis.

[96] Neutrophillic dermatosis of the hands (variant Sweet's) causes violaceous nodules, mostly on the top of the hands and digits than on the palms. [96] Histocytoid Sweet's is associated with malignancies or rheumatoid arthritis, with myeloid cell infiltration on the biopsy instead of neutrophils. Nodules, lesions, or plaques are oval, red to violet or brownish. [96] Fevers lasting many days to weeks before the onset of symptoms and during flare. [97] (Fever may be absent in MASS presentations). Headache, fatigue and malaise are common. [96] Neuro-Sweet's disease (rare). A few cases with CNS involvement, aseptic meningitis, and/or encephalitis. [97] Some cases with pustules or plaques in the exterior auditory canal and the tympanic membrane.

[97] Some cases with concurrent aortic stenosis, cardiomegaly, vascular dilation, neutrophillic myocardial infiltration, and heart failure, or other cardiac conditions. [97] A few cases with pharangeal mucosal infiltration, swelling and upper airway obstruction, pleural effusion, bronchial pustules and inflammation.

[97] Pregnancy can trigger idiopathic SS [96] [97] Hepatomegaly, splenomegaly in some cases. Some cases with: neutrophillic inflammation in the intestines, or in the hepatic portal. Inflammatory bowel disease (IBD), Crohns, or ulcerative colitis may trigger Sweet's. Hematuria, proteinuria, glomerulonephritis. [97] Splenomegaly. Some with lymphadenopathy.

Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis (PFAPA) – aka Marshall Syndrome Idiopathic Currently unknown. No genetic testing available. Currently unknown. Affects all races. [40] Unknown. PFAPA is the most common non-infectious recurrent fever disorder. [40] Periodic fevers and symptoms lasting 3-6 days, recurring every 21-28 days. Extremely predictable frequency of days between the onset flares in most cases. Patients are symptom-free between flares. No specific triggers have been identified–flares come at regular intervals, often monthly. [40] If there are any persistent symptoms between flares, evaluation for autoinflammatory periodic fever syndromes is essential. Early childhood, usually between 2-5 years of age. A few adult-onset cases are documented. Most teens outgrow it. [40] Aphthous ulcers (stomatitis), and pharyngitis with exudate, (but no infection) is a classic finding. [40] [41] Skin rashes are not typical, or a part of the PFAPA diagnostic criteria-if rashes occur with flares, or are persistent between flares, other autoinflammatory diseases should be considered. High fevers for 3-6 days, with chills and malaise. Some patients have headaches with flares. Other neurological symptoms are not noted. [41] Not noted. [40] [41] Not noted. [40] [41] Flares of fevers, stomatitis and pharyngitis are not associated with respiratory illness. [40] [41] Abdominal pain, and diarrhea are often present with flares. [40] [41] Cervical adenopathy or lymphadenopathy during flares. [40] [41] Arthralgias, fatigue and malaise. No permanent joint or bone issues noted, and patients are symptom-free between PFAPA flares. [40] [41] Not noted. [40] [41] Not noted. [40] [41] High: ESR, CRP, WBC during flares only. All normal labs when not flaring, or between flares. [40] [41] IgD may be elevated in patients with PFAPA (and these patients were negative for MVK mutations). [126] PFAPA symptoms overlaps with a number of other autoinflammatory periodic fever syndromes, so genetic testing and attention to clinical findings may be helpful.

Novartis Pharmaceuticals Canada Inc. provided The NOMID Alliance (now known as the Autoinflammatory Alliance) with an unrestricted grant in 2012 to help with the initial development & printing costs for the first comparative chart in print. An unrestricted grant from Swedish Orphan Biovitrum AB (Sobi) in 2013 supported many projects, including: the printing of the final comparative chart that we distributed at the 2013 ACR meeting, and 2014 PRYSM meeting, in addition to mailings to doctors worldwide. The NOMID Alliance has received a number of unrestricted grants at various times from Regeneron, Novartis & Sobi for grant-specific projects.
