Background Kikuchi–Fujimoto disease, which was originally described in young women, is a benign condition characterized by necrotizing lymphadenitis and fever. Even though the clinical course is usually self-limiting, it can be associated with recurrences and rarely can be associated with systemic lupus erythematosus or can be complicated with hemophagocytic lymphohistiocytosis. We report the case of a 17-year-old Sri Lankan Sinhalese schoolboy who presented with fever and cervical lymphadenopathy diagnosed as Kikuchi–Fujimoto disease and was complicated with hemophagocytic lymphohistiocytosis subsequently. Later he fulfilled the criteria for systemic lupus erythematosus. Case presentation A 17-year-old previously healthy Sinhalese schoolboy presented with high-grade fever associated with chills and rigors associated with loss of appetite and loss of weight for more than 40 days. On examination, he had bilateral firm matted tender cervical lymphadenopathy and firm hepatomegaly. An excision biopsy of his right cervical lymph node revealed necrotizing lymphadenitis and immunohistochemistry of a lymph node biopsy favored Kikuchi disease. Initial antinuclear antibody and anti-double-stranded deoxyribonucleic acid tests were negative and his C3 and C4 levels were normal. An infections screening was negative. He was treated with steroids. While in hospital he developed hemophagocytic lymphohistiocytosis and renal impairment. Later his antinuclear antibody titer became positive in 1:160 and fulfilled the diagnostic criteria for systemic lupus erythematosus. He was managed with steroids and immune suppressive drugs and showed remarkable improvement. Conclusion Although Kikuchi–Fujimoto disease is uncommon in male patients, it needs to be considered in patients with lymphadenopathy and fever. The disease can be complicated with hemophagocytic lymphohistiocytosis and the patients need continuous monitoring for the possible development of systemic lupus erythematosus later in the course.
BackgroundMelioidosis is an emerging infection in South Asia caused by Burkholderia pseudomallei with various clinical presentations that include pneumonia, bacteraemia, arthritis, and deep-seated abscesses. Various cutaneous manifestations have been described in association with melioidosis. However Sweet Syndrome secondary to melioidosis has not been reported in the literature. Herein we describe the first case of Sweet syndrome secondary to melioidosis.Case presentationA 53-year-old previously healthy Sri Lankan female presented with high-grade fever, painful oral ulcers, odynophagia and multiple bilateral cervical lymphadenopathies for 1 month. She also had a loss of appetite and weight. She had oral ulcers and bilateral blepharitis. Dermatological examination revealed multiple tender papules with a mamillated appearance and targetoid lesions with a yellowish centre over the face, upper trunk and upper limbs. She also had multiple tender subcutaneous nodules over the extensor aspect of upper limbs. Her inflammatory markers were significantly elevated. Aspirate from a submental lymph node abscess revealed the growth of Burkholderia pseudomallei. Melioidosis antibody titer was > 10,240. The histology of the skin lesions of the face and left forearm showed a prominent neutrophilic infiltrate in the dermis and the morphological features were in favour of Sweet syndrome with panniculitis. She was started on intravenous meropenem 2 g daily and showed rapid clinical improvement with the disappearance of skin lesions as well as a reduction in inflammatory markers.ConclusionSweet syndrome is an uncommon inflammatory disorder known to be associated with upper respiratory tract and gastrointestinal infections, malignancies and the use of certain drugs. Melioidosis is an emerging infection with various cutaneous manifestations. This is the first case of melioidosis causing the secondary sweet syndrome. It emphasizes the importance of considering melioidosis as a potential aetiology in patients with Sweet syndrome.
Background. Disseminated tuberculosis (TB) has been increasingly recognized in adults in the recent times due to increased prevalence of immune suppression. Here we describe a case of 47-year-old female who presented with disproportionate ascites where the diagnosis of disseminated TB was delayed. Case Report. A 47-year-old previously healthy female presented with generalised body swelling with disproportionate ascites and loss of appetite and weight for four-month duration. She denied any contact or past history of TB and reported no respiratory symptoms. Physical examination revealed significant ascites. There was no lymphadenopathy or hepatosplenomegaly. Respiratory system examination was normal. Her Erythrocyte Sedimentation Rate (ESR) was above 100. Tuberculin skin test was positive with 17mm. Contrast Enhanced Computed Tomography (CECT) abdomen revealed chronic liver disease with ascites. Diagnostic laparoscopy was in favour of miliary TB and the peritoneal biopsy revealed granulomatous inflammation with caseous necrosis, suggestive of TB. The patient was started on antituberculosis treatment and subsequently improved. Conclusion. TB peritonitis due to disseminated TB should be considered in the differential diagnosis of disproportionate ascites. Even though the diagnosis is difficult, diagnostic laparoscopy and biopsy is very helpful. It is important to have an early diagnosis since delay in treatment can be detrimental in most cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
