The diagnostic criteria and typing proposed by the Japanese Behecet Syndrome Research Committee in 1972 are as follows.
(A) Main symptoms
1.Recurrent episodes of oral ulcers.
2. Skin lesions.
(1) Nodular erythema.
(2) Subcutaneous thrombophlebitis.
(3) Positive skin prick reaction.
3.Ocular lesions.
(1) Recurrent anterior chamber pus accumulation iridocyclitis.
(2) Choroidal retinitis (retinal vasculitis).
(4) Genital ulcers
(II) Secondary symptoms
1.Arthritis (red, swollen, painful joints)
2, gastrointestinal lesions (appendicitis-like abdominal pain, black stool, etc.)
3.Epididymitis
4.Vascular lesions (occlusive vascular disorders, aneurysms)
5, central nervous system lesions (brainstem syndrome, meningoencephalitis syndrome, etc.)
(C) Classification
1.Complete type: skin, oral cavity, genitalia and eye symptoms all appear
2. Incomplete type: 3 major symptoms appear
3.Suspicious type: 2 main symptoms
4.Probable type: 1 main symptom
The diagnosis can be made by having 2 or more of the above 4 symptoms or a combination of major and minor symptoms.
The diagnostic criteria (ISG) proposed by the International Behcet Syndrome Study Group are as follows.
(A) Recurrent oral ulcers
A small or large ulcer or herpes-like ulcer found by the physician or patient that recurs at least 3 times in 1 year.
(ii) Combination of two of the following
1. Recurrent genital ulcers: ulcers found by the physician or patient or scar formation due to ulcers.
2.Ocular damage: anterior and posterior uveitis, intravitreal hemorrhage under slit lamp, retinal vasculitis.
3, skin damage: erythema nodosum, pseudofolliculitis or papular or pustular damage, or post-pubertal acne-like nodules, and the patient has not been treated with glucocorticoids.
4, skin needling reaction: positive within 24-48 hours after needling and cannot be explained by other clinical conditions.
