A 26-year-old man presents to your office with fever, chills, and malaise.

Disseminated gonococcal infection (DGI) typically presents with the classic triad of polyarthralgia, tenosynovitis, and skin lesions (especially pustules on extremities). A prior urogenital infection and systemic symptoms further support this diagnosis.

Toronto Notes 2023 – Infectious Disease, STIs:

“DGI presents with arthritis-dermatitis syndrome: fever, asymmetric polyarthralgia, tenosynovitis, and vesiculopustular skin lesions. It may follow asymptomatic or unrecognized urogenital infection.”

MCCQE1 Objectives – Infectious Disease > STIs:

“Candidates must recognize systemic manifestations of gonorrhea including DGI and distinguish it from other forms of arthritis or systemic illness.”

Reactive arthritis (C) may follow STI but includes conjunctivitis and urethritis. HIV (A) does not typically cause this triad. RA (D) has different distribution and chronicity. Varicella (E) presents with diffuse vesicular rash, not joint pain.
