| Abstract|| |
Kikuchi's disease (KD) also known as histiocytic necrotizing lymphadenitis is rare, idiopathic, generally self-limited cause of lymphadenitis. We present a case of twenty year young female who presented in critically ill state with fever, cervical and axillary lymphadenopathy, rash, vomiting and altered sensorium and found to have neurological, hepatic, renal and dermatological involvement. Kikuchi's disease should be considered in differential diagnosis of fever and lymphadenopathy and though benign can sometimes present with multi-organ involvement. It is because of rarity of this disease with unusual complications, present case is reported.

| Introduction|| |
Kikuchi's disease (KD) is rare, idiopathic, generally self-limited cause of lymphadenitis. It is also known as histiocytic necrotizing lymphadenitis and Kikuchi-Fujimoto disease More Details. Kikuchi first described the disease in 1972 in Japan. Fujimoto et al. independently described the disease in the same year.
The disease is usually limited to lymph nodes, but the involvement of skin, liver, spleen, and even neurological involvement and fatalities have been reported. Rare neurologic complications include aseptic meningitis, acute cerebellar ataxia, encephalitis, photophobia, mononeuritis multiplex, brachial neuritis, and hemiparesis., However, only a few cases of acute kidney injury (AKI), peripheral neuropathy along with aseptic meningitis and cutaneous involvement following KD have been reported.
| Case Report|| |
A 20-year-old female patient presented with a history of high-grade fever, vomiting and myalgia for the past 4 days and rash over the abdomen, back, and upper limbs along with altered sensorium for 1 day. There was no history of a cough, dyspnea, chest pain, and any weakness. History of low-grade fever along with neck and axillary swellings for 4 months was present and she has received multiple courses of antibiotics during this period.
Her vital signs on admission were as follows: glasgow coma scale score was 10/15 (E2, M4, V4), pulse-118 beats/min, blood-pressure 70 mmHg systolic, febrile and had multiple, palpable, nontender lymph nodes 2 cm × 2 cm in both sides of the neck and left axilla. Petechial rashes were noted over the abdomen, back and both upper limbs [Figure 1]a, which decreased by the 5th day [Figure 1]b. On central nervous system examination, she was drowsy, and neck rigidity was present. Rest systemic examination and fundoscopic examination were normal.

Pertinent laboratory data showed: hemoglobin 12.6 g/dl, total leukocyte count 14,100/cu mm, platelets 1.22 lakhs/ul, and peripheral smear showed neutrophil leukocytosis. Her urine analysis revealed albuminuria with microscopic hematuria. Renal function tests (serum creatinine-2.40 mg/dl; blood urea nitrogen-67 mg/dl) were suggestive of acute renal failure; and her ultrasound abdomen was normal. Other parameters such as blood sugar, electrolytes, arterial blood gas reports, chest X-ray, and computed tomography scan head were normal. Liver function test revealed aspartate amino transferase – 408 and alanine aminotransferase – 460 with raised lactate dehydrogenase (LDH) levels of 4822 mg/dl. She tested negative for serological tests for malaria antigen, dengue, Paul Bunnell test (heterophil agglutinins and specific Epstein-Barr virus antibodies for diagnosis of infectious mononucleosis), leptospira, and HIV. Her rheumatologic markers such as rheumatoid factor, anti-nuclear antibody, anti-double-stranded DNA, anti-perinuclear neutrophil cytoplasmic antibody were also negative.
Her lumbar puncture was done, and cerebrospinal fluid (CSF) glucose was 69 mg/dl, protein was 299 mg/dl, CSF cytology showed neutrophils. However, culture and ADA were negative and suggestive of acute aseptic meningitis.
She underwent fine-needle aspiration cytology and excision biopsy from cervical lymph nodes. Histopathology showed large paracortical, well-circumscribed necrotic lesions, with a starry-sky appearance because of tangible macrophages [Figure 2]a. There was extensive karyorrhexis, fibrin deposits, plasmacytoid monocytes, phagocytic foamy histiocytes and rare plasma cells [Figure 2]b. There were no neutrophils, no follicular hyperplasia, and no atypia. Granuloma formation was not seen. There was no arteritis. Histopathology findings revealed histiocytic necrotizing lymphadenitis suggestive of KD.

She was started on injectable steroids, antibiotics, and analgesics with significant improvement in her symptoms. Four days later, she developed new lesions in lower limbs in the form of palpable purpura along with bilateral wrist drop [Figure 3]a and foot drop [Figure 3]b. We suspected vasculitis to be the cause for her condition and continued on steroids. Nerve conduction study revealed severe motor plus sensory axonal neuropathy. A diagnosis of KD with aseptic meningitis with AKI and bilateral motor plus sensory axonal neuropathy was made.

Skin biopsy could not be done as the patient was not willing for same. Clinical improvement with full recovery of sensorium and renal function was observed after 10 days. She was discharged on oral steroids and physiotherapy following which there is a gradual improvement in power of wrist and foot, but it did not improve completely when she came for follow-up after 1 month.
| Discussion|| |
KD should be considered as a differential diagnosis of lymphadenitis. The course of KD is usually benign and self-limited (resolves over a period of few weeks to 6 months). The exact cause of KD is not known but considered as an autoimmune phenomenon as several authors have reported an association with viral diseases and SLE.
Common manifestations of KD are cervical lymphadenopathy, rarely generalized lymphadenopathy, flu-like syndrome in almost half of the patients including fever, headache, vomiting, arthralgia, myalgia, and weight loss. Skin involvement includes rash, maculopapular lesions, nodules, and urticaria. Rare involvement of joints, thyroid, parotid glands, and hepatosplenomegaly with elevated levels of liver enzymes and LDH and fatal outcome from myocardial involvement has been reported., The patient had usual manifestations, i.e., fever, lymphadenopathy, as well as uncommon involvement in the form of rash, hepatic, renal as well as neurological involvement in the form of aseptic meningitis and peripheral neuropathy.
We ruled out close differential diagnoses of our case, i.e., lymphoma, leukemia, tuberculosis, infectious mononucleosis, SLE, rheumatoid arthritis, and also ruled out causes for her acute illness.
The occurrence of peripheral neuropathy is rare in KD. We presumed that neuropathy in our patient was secondary to cryoglobulinemia, which may occur without any apparent condition or it accompanies chronic infection. In cryoglobulinemia, distal symmetrical peripheral neuropathy occurs in association with Raynaud phenomenon and purpuric eruptions of the skin. It evolves over a period of few days, more in the legs than in the arms and more common in the distribution of vascular changes as seen in our patient. The mechanisms by which cryoglobulinemia disorders causes neuropathy is uncertain, however acute vasculitic neuropathy was mentioned earlier.
We treated her both with steroids and antibiotics, and she responded promptly. Immunosuppressants have been recommended in severe, life-threatening disease. However, we did not start her on cyclophosphamide as our patient responded to steroid therapy.
| Conclusion|| |
It is important to remember KD as a rare cause of lymphadenopathy in young individuals. The treatment of KD is mainly supportive, and use of corticosteroids is recommended in severe extranodal or generalized KD.
