SAEM Clinical Images Series: Connect the Dots
The patient is a 39-year-old female with past medical history of polysubstance use disorder and seizures who presents to the Emergency Department complaining of bilateral leg pain, primarily in her joints. She states that she was seen by her PCP today and was given a shot of Toradol, but she reports that her pain has continued to worsen to the point that she has difficulty ambulating. She states that two days ago she developed pruritic blisters on her feet and her feet began to swell. She reports the blisters have worsened and have spread to her hands and forearms as well as her calves and thighs. She denies ever having similar symptoms in the past. She reports some subjective fevers and chills as well as cough and congestion, but denies sore throat, chest pain, abdominal pain, vomiting, diarrhea, dysuria, vaginal bleeding, or vaginal discharge.

This patient has disseminated gonococcal infection.
Disseminated gonococcal infection (DGI) is a serious complication of untreated gonorrhea, potentially leading to severe complications such as septic arthritis, pustular skin lesions, tenosynovitis, and in rare cases, endocarditis or meningitis. DGI is characterized by fevers, polyarticular joint pain, and skin lesions. The diagnosis of disseminated gonorrhea should be considered in any patient presenting with polyarticular joint pain or swelling in the setting of petechial or pustular skin lesions, especially in high risk populations. The skin lesions of disseminated gonorrhea most commonly appear on the distal extremities, and may involve the palms and soles. Patients may also present with acute septic arthritis without an obvious source. Patients with gonoccocal bacteremia may show signs of perihepatitis, meningitis, endocarditis, or osteomyelitis. Disseminated gonococcal infection results from the hematogenous spread of N gonorrhoeae, and typically develops within 3 weeks of primary mucosal infection. Patients with disseminated gonoccocal infection should be admitted for intravenous antibiotics (ceftriaxone). Any sexual partners should be treated as well.
Take-Home Points
Consider disseminated gonorrhea when you have a patient with polyarticular joint pain/swelling with pustular skin lesions.
Complications of DGI may be severe; admission and aggressive treatment with intravenous antibiotics is warranted.
