We report a rare case of systemic amyloidosis with gastrointestinal and lymph node involvement. A 64-year-old woman was admitted to our hospital with dyspepsia and weight loss. Initial esophagogastroduodenoscopy (EGD) revealed nonspecific findings, and abdominal computed tomography showed necrotizing lymphadenopathy at the porta hepatis. Laparoscopic lymph node biopsy was performed under suspicion of tuberculous lymphadenopathy, but a definite diagnosis was not established. Follow-up EGD performed 6 months later revealed multiple telangiectasia-like lesions at the gastric body, and endoscopic biopsy revealed amyloid deposition. Through additional blood and urine protein electrophoresis, the patient was finally diagnosed with systemic amyloidosis associated with multiple myeloma. She was treated with dexamethasone, thalidomide, and bortezomib; however, she died 3 months after diagnosis because of pneumonia and multiple organ failure.

톡소카라증은 생간의 섭취 혹은 개의 분변으로 오염된 토양으로부터 인간에게 감염되어 호산구 증가증을 일으키는 기생충 질환으로 뇌, 눈, 폐, 간 등 다양한 장기에 증상을 일으킬 수 있다. 호산구 침윤이 일어난 장기에 따라 간 병변을 유발하거나 장벽 비후 및 복수의 증가로 나타나는 경우가 보고된 바 있으나 전신 림프절의 증대로 나타나는 것은 극히 드물다. 전신 림프절 증대로 나타난 톡소카라증은 현재까지 약 두 개의 증례 보고가 흉부와 경부, 서혜부에서 보고된 바 있다. 하지만 전신 림프절 증대로 인해 림프종으로 오인되었던 톡소카라증은 보고된 바 없어 이러한 드문 형태로 발현된 톡소카라증에 대해 증례 보고를 하고자 한다.

Multiple studies have reported on unilateral axillary adenopathy following coronavirus disease 2019 (COVID-19) vaccination, which is currently recognized as a common finding. Here, we present a series of eight adult patients with reactive axillary lymphadenopathy following COVID-19 vaccination, in whom the follow-up ultrasonography (US) showed resolution of a previously noted unilateral axillary adenopathy. From March 2021 to March 2022, 2,599 consecutive women underwent breast US in Jeju National University Hospital. We identified 10 patients with unilateral axillary lymphadenopathy following COVID-19 vaccination detected on the breast US. The 10 patients were recommended for follow-up US. Two patients were lost to follow-up, whereas the remaining eight patients underwent follow-up US, in whom resolution of the unilateral axillary lymphadenopathy was noted. Radiologists should be aware of evolving guidelines for evaluating and managing axillary lymphadenopathy to avoid false positive biopsies. Recent studies on lymphadenopathy following COVID-19 vaccination show that a prolonged duration until resolution is often observed. Therefore, a follow-up US examination at least 12 weeks after vaccination may be reasonable. Furthermore, management guidelines should include a risk-stratified approach considering both vaccination timing and the patient's overall risk of metastatic disease.

Systemic lupus erythematosus(SLE) is a multisystemic disorder of autoimmune etiology. SLE can occur commonly in young women, and the early symptoms include fever, myalgia, arthralgia, weight loss, lymphadenopathy and these nonspecific symptoms develop into skin rash, splenomegaly, serositis and encephalopathy. Diagnosis of SLE requires clinical and serologic criteria, and treatment choices are hydroxyquinolone and NSAIDs for mild disease, corticosteroids and immunosuppressant for severe disease. In lupus patient, the prevalence of lymphadenopathy is 12~59%. Although lymphadenopathy is common finding in SLE, it is hard to distinguish in early phase of SLE. A 38-year-old woman visited our hospital for cervical lymphadenopathy with polyarthritis and malaise. Multiple cervical lymph nodes enlargement was found on Neck CT, and serologic laboratory test including ANA, antiphospholipid antibody, and anti-dsDNA was positive. For excluding lymphoma, PET-CT and excisional biopsy were performed. The patient finally diagnosed with SLE, and got regular follow-up without complication.

Multicentric Castleman disease (MCD) is an uncommon systemic lymphoproliferative disorder that may cause multiple organ damage. Castleman disease-associated diffuse parenchymal lung disease (DPLD) has not been well studied. A 32-year-old man was referred to our hospital for progressive generalized weakness, light-headedness, and dyspnea on exertion for more than one year. Laboratory evaluations showed profound anemia, an elevated erythrocyte sedimentation rate, and an increased C-reactive protein level with polyclonal hypergammaglobulinemia. Chest radiography, computed tomography (CT), and positron emission tomography-CT scan demonstrated diffuse lung infiltration with multiple cystic lesions and multiple lymphadenopathy. In addition to these clinical laboratory findings, bone marrow, lung, and lymph node biopsies confirmed the diagnosis of idiopathic MCD (iMCD). Siltuximab, an interleukin-6 inhibitor, and glucocorticoid therapy were initiated. The patient has been tolerating the treatment well and had no disease progression or any complications in 4 years. Herein, we report this case of human herpesvirus-8-negative iMCD-associated DPLD accompanied by multiple cystic lesions, multiple lymphadenopathy, and polyclonal hypergammaglobulinemia with elevated immunoglobulin G (IgG) and IgG4 levels. We recommend a close evaluation of MCD in cases of DPLD with hypergammaglobulinemia.

BACKGROUND: Kawasaki disease (KD) sometimes presents with only fever and cervical lymphadenopathy before other clinical signs materialize. This lymphadenopathy-first-presenting Kawasaki disease (LKD) may be misdiagnosed as bacterial cervical lymphadenitis (BCL). We investigated characteristic imaging and clinical data for factors differentiating LKD from BCL. METHODS: We compared imaging, clinical, and laboratory data of patients with KD and BCL. We included patients admitted to a single tertiary center between January 2015 and July 2018. RESULTS: We evaluated data from 51 patients with LKD, 63 with BCL, and 218 with typical KD. Ultrasound imaging revealed multiple enlarged lymph nodes in both LKD and BCL patients. On the other hand, computed tomography (CT) showed more abscesses in patients with BCL. Patients with LKD were younger and showed higher systemic and hepatobiliary inflammatory markers and pyuria than BCL patients. In multivariable logistic regression, younger age and higher C-reactive protein (CRP) retained independent associations with LKD. A comparison of the echocardiographic findings in LKD and typical KD showed that patients with LKD did not have a higher incidence of coronary artery abnormalities (CAA). CONCLUSIONS: LKD patients tend to have no abscesses on CT and more elevated systemic hepatobiliary inflammatory markers and pyuria compared to BCL patients. The absence of abscess on CT, younger age, and elevated CRP were the most significant variables differentiating LKD from BCL. There was no difference in CAA between LKD and typical KD.

Progressive transformation of germinal centers (이하 PTGC)는 드물게 나타나는 양성 림프절 질환으로, 주로 만성적인 림프절 비대의 형태로 나타난다. 주로 한 개 또는 여러 개의 림프절의 무통성 비대로 나타나며, 가장 흔히 침범하는 부위는 경부 림프절, 다음으로 액와부와 서혜부 림프절로 알려져 있다. 일부 환자들에서는 조직병리에서 림프종이 함께 존재하기도 하지만, PTGC 자체는 전암병변으로 인식되지는 않는다. 조직학적으로 PTGC로 진단되는 경우도 적지만, 이에 대한 영상의학적 소견은 거의 보고된 바가 없다. 이에 저자들은 침윤성 유방암 환자에서 수술 후 반대편 액와부 림프절 비대로 나타나 전이성 림프절로 오인한 PTGC 증례의 영상 소견을 보고하고자 한다.

Disseminated mycobacterial infection after bacillus Calmette-Guerin (BCG) vaccination is a very rare disorder, occurring mostly in patients with immunologic deficiency. We report a case of disseminated BCG infection in a 16-month-old girl with severe combined immunodeficiency. Plain radiographs showed multiple osteolytic lesions in the femora, tibiae, humerus, and phalanges. Abdominal sonography and CT scanning revealed multiple nodules in the spleen, and portocaval lymphadenopathy.

Langerhans' cell histiocytosis is a relatively rare disorder of children, characterized by abnormal proliferation of Langerhans' cells. It usually presents as multiple osteolytic lesion with lymphadenopathy or cutaneous manifestations. We experienced a case of Langerhans' cell histiocytosis involving bone and lymph node, diagnosed by fine needle aspiration cytology of the lymph node. The patient was a 10-year old girl with left inguinal lymphadenopathy. Fine needle aspiration cytology from the lymph node disclosed very cellular smear consisted of Langerhans' cells, eosinophils and lymphocytes. The Langerhans' cells had eccentric oval to reniform shape nuclei with grooving and abundant pale cytoplasm. The diagnosis was confirmed later by histologic study of bone lesion.
