Reactive arthritis in India: a dermatologists' perspective.

BACKGROUND: The mucocutaneous lesions in Reiter syndrome (RS) or reactive arthritis are seen quite frequently.

MATERIALS AND METHODS: The case records of patients admitted with the diagnosis of RS from January 2006 to December 2010 were reviewed. Data regarding the demographic details; course of musculoskeletal, mucocutaneous, and ophthalmic involvement; body surface area affected; morphology of lesions; investigations undertaken; and treatment instituted were recorded. Based on these, the disease was classified as complete or incomplete RS.

RESULTS: The case records of 11 patients were evaluated. There were seven males and four females. Only two patients had complete RS, whereas nine patients had incomplete RS. Arthritis and mucocutaneous involvement were seen in all 11 patients, whereas preceding urethritis/dysentery was seen in 4 patients and eye symptoms in 4 patients. Enthesitis was seen in eight patients (72.7%). Circinate balanitis/vulvitis was present in six patients and keratoderma blenorrhagicum in eight patients. The most frequent radiologic finding was juxta-articular osteopenia in eight patients.

CONCLUSION: RS may not show the typical triad in all cases, although musculoskeletal disease is seen in a significant proportion of patients. In the absence of typical signs and symptoms, cutaneous manifestations may help establish the diagnosis of RS.
