Behcet disease is a systemic inflammatory vasculitis of unknown etiology, though likely autoimmune in nature.

Areas of involvement include:

Oral ulcers

Genital ulcers

Ocular disease

Cutaneous lesions

Neurologic disease

Vascular disease

Cardiac disease

Gatrointestinal disease

Articular involvement

The sensitivity and specificity of findings for Behcet Disease are listed below. See the left navigation bar to change the display.

Poorly Diagnostic Findings

Finding	Sensitivity	Specificity	Comments, Study
Genital Ulcer	Sensitivity = 57%		Genital ulcers occur in 57-93% of patients. Perineal, perianal and groin lesions can occur in both sexes. For males: Scrotum lesions are most frequent (90%) while penile lesions are infrequent. For females: vulvar, vaginal and cervical lesions are common Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519
Oral ulcer	Sensitivity = 47%		Oral ulcers are the major manifestation of Behcet disease. They usually occur in 47-86% of patients. The oral ulcers can precede onset of other symptoms by many years. See article for description of the lesions: Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519
Cutaneous lesions	Sensitivity = 38%		Skin involvement occurs in 38-99% of patients. Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519

Findings With Unspecified Accuracy

Finding	Sensitivity	Specificity	Comments, Study
Uveitis	No accuracy specified.		Ocular disease is commonly bilateral and tends to occur 2-3 years after onset of Bechet disease syndromes. However, it is the presenting feature in 10-20% of patients. Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519
Blurred Vision	No accuracy specified.		Part of ocular disease Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519
Photophobia	No accuracy specified.		Part of ocular disease Study: Behçet's disease--a contemporary review. Mendes D, Correia M, Barbedo M, Vaio T, Mota M, Gonçalves O, Valente J. J Autoimmun. 2009 May-Jun;32(3-4):178-88. Epub 2009 Mar 26. PMID 19324519
Pathergy	No accuracy specified.		Sensitivity and specificity not specified The pathergy test consists of the intradermal puncture of the skin with a 20 gauge or smaller needle 5mm obliquely into the patient's flexor aspect of the avascular forearm skin under sterile conditions and without injecting saline. The test is considered positive when an indurated erythematous small papule or pustule forms within 48 hours. Study: Behçet's disease--a contemporary review.
