Kikuchi Disease Clinical Presentation

History
Kikuchi disease most frequently manifests as a relatively acute onset of cervical adenopathy associated with fever and a flulike prodrome.
- Lymphadenopathy
- Cervical nodes are affected in about 80% of cases.
- Posterior cervical nodes are frequently involved (65-70% of cases).
- Lymphadenopathy is isolated to a single location in 83% of cases, but multiple chains may be involved.
- Cases of generalized adenopathy involving axillary, inguinal, and mesenteric nodes are unusual.
- A flulike prodrome with fever is present in 50% of cases. The following are less common symptoms:
- Headache
- Nausea, vomiting
- Malaise, fatigue
- Weight loss
- Arthralgias, myalgias
- Night sweats
- Rash (up to 30%)
- Thoracic/abdominal pain
Physical
- Lymphadenopathy
- Lymphadenopathy is isolated to 1 location in 83% of patients, although multiple nodal chains may be involved.
- Cervical nodes are affected in 80% of patients; of these, 65-70% involve posterior triangle cervical nodes.
- Less commonly affected nodes include those in axillary, mediastinal, celiac, abdominal, and inguinal locations.
- The nodes are usually described as painless or mildly tender.
- The nodes tend to be 2-3 cm in diameter, although masses of multiple nodes may reach 6 cm.
- The nodes are usually firm and mobile, but they are not fluctuant or draining.
- Extranodal findings
- Skin[20, 21]
- The incidence of skin involvement varies from 5-30%.
- Findings are varied and nonspecific and include maculopapular lesions, morbilliform rash, nodules, urticaria, and malar rash, which may resemble that of SLE.
- Skin lesions resolve in a few weeks to months.
- Hepatosplenomegaly
- This finding is not uncommon.
- Monitor lactase dehydrogenase (LDH) levels.
- Neurologic involvement
- Neurologic involvement is rare but has included conditions such as aseptic meningitis, acute cerebellar ataxia, and encephalitis.[22]
- Patients with aseptic meningitis may report headache, but they do not exhibit nuchal rigidity or positive Kernig or Brudzinski signs. Cerebrospinal fluid (CSF) findings are similar to those noted in patients with aseptic meningitis of viral etiology.
- Rarely involved extranodal sites include the bone marrow, myocardium, uvea, and thyroid and parotid glands.
- Arthritic involvement was reported in the case of a 14-year-old body.[2]
- Widespread involvement of multiple organ systems in Kikuchi disease has been described in solid-organ transplant patients.
