Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis (HNL), is a rare, self-limiting disease most commonly reported in young Asian women worldwide. We present the case of a 27-year-old African American male who had three weeks of high-grade fevers, night sweats, a 10-pound weight loss, and tender unilateral posterior cervical lymphadenopathy. A complete workup of infectious, rheumatologic, and neoplastic diseases was pursued. Lymph node biopsies revealed histiocyte proliferation with areas of necrosis. These findings were diagnostic of KFD. While KFD has been reported most commonly in young Asian women, in the US, this disease must be considered in both males and females and in diverse ethnicities.

Acute myeloid leukemia (AML) is a complex disease with a variety of presentations. A large pericardial effusion is rare, occurring in less than 0.5% of all patients with AML prior to treatment. A 34-year-old male presented with dyspnea, malaise, and weight loss. On physical exam, he was noted to be hypoxic, tachypneic, tachycardic, and hypotensive. He had cervical lymphadenopathy and jugular venous distention. His WBC count was 110 bil/L with 33% blasts. Bone marrow biopsy confirmed AML with 60% blasts. Leukemic cells were also seen in the cerebrospinal fluid on lumbar puncture. An echocardiogram revealed a large pericardial effusion causing tamponade. He underwent emergent pericardiocentesis, and malignant cells were present in the pericardial fluid. Induction therapy with standard dose cytarabine and daunorubicin was initiated, and bone marrow biopsy 14 days later showed no residual AML. This case demonstrates the importance of a thorough evaluation of each organ system when caring for a patient with AML.
- Diagnostic performance of ATA, BTA and TIRADS sonographic patterns in the predication of malignancy in histologically proven thyroid nodules. [Journal Article]
- SMSingapore Med J 2018 May 18
- CONCLUSIONS: Our study showed that sonographic patterns outlined by the three guidelines have high sensitivity and NPV. Although isolated suspicious US features cannot predict malignancy risk, they should be considered when risk stratifying nodules that do not fit into particular sonographic patterns based on current guidelines.

A 24-year-old man complained of a right temporal headache for four weeks. The patient denied any trauma or previous anticoagulation use. He also reported tender right facial swelling. His physical exam was unrevealing except for right cranial nerve (CN) VI palsy, right parotid enlargement, and cervical adenopathy. Laboratory findings were significant for mild leukopenia at 3300 cells/uL. The computed tomography (CT) scan obtained showed a chronic left subdural effusion with a 4 mm midline shift and confirmed right parotid enlargement and cervical lymphadenopathy. Surgical burr hole evacuation was done and the fluid was sent for wound culture analysis. The infectious diseases service recommended initiating antibiotics, which were later stopped due to cerebrospinal fluid (CSF) cultures with no growth of any organisms. His CN VI palsy resolved during admission. The patient was discharged with follow-up for biopsy. The patient was lost to follow-up. The patient presented to the emergency department (ED) three months later, with a left-sided frontal headache. A repeat CT scan showed a new, right-sided fluid collection outside the brain parenchyma. Burr hole evacuation was done again and purulent fluid was drained. Antibiotics were held this time, but anti-tuberculous therapy was initiated empirically. The otolaryngology service was consulted and a lymph node biopsy was performed. The pathology showed histiocytic necrotizing lymphadenitis. A dural biopsy was done as well and was consistent with histiocytic necrotizing lymphadenitis involving the dura. Cultures from the subdural fluid did not grow any organism. The patient remained neurologically intact. He improved after surgery was done to drain the fluid and was managed by analgesics. The cultures from the extra-parenchymal fluid collection remained negative for pathogens and tuberculous mycobacteria. The patient was discharged with rheumatology clinic follow-up. He saw the rheumatologist six weeks after the discharge. During his clinic visit, the patient reported no recurrence of headaches, fevers, rash, or joint pain. Our patient had a rare presentation of Kikuchi-Fujimoto disease, in which he had a subdural fluid collection resulting in neurological complications that required surgical intervention.

Objective: To explore the value of Positron-Emission Tomography/Computed Tomography (PET/CT) in the prognosis of extranodal NK/T cell lymphoma. Methods: The patients of NK/T cell lymphoma diagnosed from January 2007 to July 2016 in Department of Pathology of Beijing Tongren Hospital were enrolled in this study. Seventy-two in-hospital patients were examined on the invasion of adjecent tissue or organ by PET/CT. The PET/CT results were analyzed retrospectively. Kaplan-Meier method was used to analyze the prognostic value of the positive results by PET/CT on overall survival (OS). Results: There were 54 males and 18 females with median age of 44.5 years (13-75 years). According to Ann Arbor staging system, there were 16 cases (22.2%) in stage Ⅰ, 29 cases (40.3%) in stage Ⅱ, 6 cases (8.3%) in stage Ⅲ and 21 cases (29.2%) in stage Ⅳ. According to the IPI scoring system, there were 34 cases (47.2%) in the low risk group (0-1 point), 21 cases (29.2%) in the low-middle risk group (2 points), 16 cases (22.2%) in the middle-high risk group (3 points), and 1 case (1.4%) in the high risk group (4-5 points) . The median follow-up time was 29.2 months (1-118 months). The disease occured in unilateral nasal cavity in 26 cases (36.1%), bilateral nasal cavities in 36 cases (50.0%), nasopharynx, oropharynx and pharynx in 10 cases (13.9%). The tumors of 51 cases involved the surrounding tissue, including nasal wings in 29 cases (40.3%), nasal sinus in 29 cases (40.3%), maxillofacial soft tissue in 18 cases (25.0%), orbital in 12 cases (16.7%), maxilla and skull base in 8 cases (11.1%), eyelid in 6 cases (8.3%), brain tissue in 3 cases (4.2%), eyeball in 2 cases (2.8%). In addition, cervical and inguinal lymphadenopathy were found in 54 cases (75.0%) . Splenomegaly and hepatomegaly were found in 10 cases (13.9%) and 2 cases (2.8%), respectively. Survival analysis showed that the clinical stage and IPI were significantly associated the clinical prognosis (P=0.000, 0.001, respectively). Involvement of the maxillofacial soft tissue, eyelid, orbital, maxilla and skull base and brain tissue were significantly related to reduced the overall survival time (P=0.006, 0.000, 0.024, 0.001 and 0.015, respectively). Involvement of palate or tonsil, the nosewingand nasal sinus did not show significant shorter overall survival (P=0.091, 0.063, and 0.139, respectively). Cox regression multivariate analysis showed maxilla and skull base involvement was independent adverse prognostic factor (P=0.047). Conclusions: The PET/CT examination can accurately detect the extent of adjacent and distant tissues of tumor involvement of NK/T cell lymphoma by showing the tumor structure and metabolic status, thus has important value in the clinical staging and prognosis predication.

The definition of nodal and/or mucosal target volumes for radiation therapy for lymphadenopathies of unknown primary is controversial. Target volumes may include all nodal areas bilaterraly and be pan-mucosal or unilateral, selective, including the sole oropharyngeal mucosa. This review presents current recommendations in light of changes in the TNM classification, Human papillomavirus status and therapeutic advances. We conducted a systematic review of the literature with the following keywords: lymphadenopathy; head and neck; unknown primary and radiation therapy. There are no direct comparative studies between unilateral or bilateral nodal irradiation or pan-mucosal and selective mucosal irradiation. Contralateral lymph node failure rates range from 0 to 6% after unilateral nodal irradiation and 0 and 31% after bilateral irradiation. Occurrence of a mucosal primary varies between 0 and 19.2%. Initial clinical presentation and Human papillomavirus status are critical to define mucosal target volumes. Intensity-modulated radiotherapy is recommended (rather than three-dimensional irradiation) to avoid toxicities. Systemic treatments have similar indications as for identified primary head and neck cancers. Failures do not appear superior in case of unilateral nodal irradiation but comparative studies are warranted due to major biases hampering direct comparisons. Human papillomavirus status should be incorporated into the therapeutic strategy and practice-changing TNM staging changes will need to be evaluated.

Carotid body tumors are rare childhood extra-adrenal paragangliomas. We present an 8-year old female with a neck mass mistaken as reactive lymphadenopathy. Computed tomography and magnetic resonance angiography, as well as preoperative embolization and balloon test occlusion, were utilized for planning and management. Surgical excision of the tumor was successful and pathological examination revealed a benign paraganglioma. Surgical treatment is curative for these benign lesions, however rare cases have presented years later with metastatic disease. Therefore, a child, like our patient, will require lifelong surveillance for the development of potential metastasis.
