Objective: The clinical presentation, outcome, and risk factors for mortality in children with Fever of Unknown Origin (FUO) were determined. Methods: Medical records of pediatric patients admitted for FUO from January 2009 to December 2013 were reviewed. Clinical manifestations, physical exam findings, diagnostic work-ups and final diagnosis were determined, as well as the relationship between final diagnosis and risk for mortality. Results: Fifty-seven patients with FUO were included. Weight loss, cough, colds, and rashes were common symptoms while pallor, lymphadenopathies, and hepatomegaly were common physical exam findings. All patients underwent Phase I evaluation for FUO, while 73.7% underwent further diagnostic tests. A specific etiology was established in 96.5% of cases: infectious, 43.9%, connective tissue disease, 38.6%, and hematologic/oncologic, 14%. Two cases remained to have no specific diagnosis. Majority of patients had a benign course and were discharged improved (84.2%). The mortality rate is 15.8% and was not associated with any disease category (p-value 0.204). Conclusion FUO in children occurs across all age groups. Its clinical presentations are varied and non-specific and common signs and symptoms are pallor, lymphadenopathies, weight loss, cough, colds. and joints pains. Infection is the most common cause of FUO in children, followed by connective tissue diseases and hematologic and oncologic diseases. The mortality rate from FUO is 15.8%.

Aortic dissection most often presents with the severe chest pain and may have variable symptoms including fever. However, fever of unknown origin as the predominant manifestation of aortic dissection seems to be extremely rare. We report the case of a patient who sustained a prolonged spiking fever with unknown origin for 17 days following acute aortic dissection. The case serves as a reminder that prolonged fever may be the principal residual sequelae after aortic dissection.

Objective: To present a unique case of intravascular lymphoma of the inferior turbinate because of its rarity, unusual clinical presentation and difficulty in establishing a diagnosis. Design: Case Report Setting: A tertiary hospital Patient: A 66-year-old male admitted to the hospital due to intermittent high grade fever of six months duration. Result: The patient presented with fever of unknown origin, and exhaustive laboratory, ancillary procedures and biopsies to rule in/out infectious, autoimmune and oncologic causes were performed to arrive at a diagnosis. Nasal endoscopy revealed an enlarged, hypertrophied and violaceous right inferior turbinate with watery to mucoid discharge and septal deviation to the right confirmed by CT scans of the paranasal sinuses. Functional Endoscopic Sinus Surgery (FESS), septoplasty and turbinoplasty with biopsy revealed intravascular lymphoma. Chemotherapy was deferred due to the deteriorating medical condition and the patient expired seven months after the initial onset of symptoms. Conclusion: Patients who present with fever of unknown origin should undergo a thorough otorhinolaryngologic examination to exclude primary ENT conditions and ensure proper management. Given its rarity and multiplicity of presentation, it is extremely difficult to make a diagnosis of intravascular lymphoma. A high index of suspicion of intravascular lymphoma is necessary so that timely acquisition of tissue biopsy of any lesion involved will make a definite diagnosis. (Author)
LYMPHOMA FEVER FEVER OF UNKNOWN ORIGIN CASE REPORTS

Cytologic examination of the body cavity fluid is very important because the specimens represent a significant percentage of nongynecologic samples and this cytologic examination may be the first, best or only chance for making the diagnosis of an underlying malignancy. The purposes of body cavity fluid examination are to correctly identify cancer cells and if possible, to identify the tumor types and primary sites when presented with unknown primary tumor sites. The most important basic differential diagnosis is that of benign and reactive disease vs malignant disease. Reactive mesothelial cells are a consistent population in body cavity fluid, and these are the most versatile cells in the body. Due to the specific environment of the body cavity, the exfoliated reactive mesothelial cells may show significant morphologic overlap with the morphology of cancer cells. With a focus on the differential points between reactive mesothelial cells and metastatic adenocarcinoma cells, the practical diagnostic approaches, the diagnostic clues and the pitfalls to achieve a correct diagnosis are presented in this review.

Relapsing polychondritis is a rare autoimmune disease of unknown etiology with episodic but potentially progressive inflammatory manifestations. Auricular, articular and nasal manifestations are the most frequent disturbances. Fever is one of the manifestations of this disease but it rarely appears as an initial presentation. In this situation, the diagnosis is delayed until other manifestations are obvious. We report a case of relapsing polychondritis, which was presented as fever of unknown origin. Ten months after the onset of fever, auricular chondritis appeared and gave us the key to diagnosis.

Extra-nodal malignant lymphoma is often characterized by a lack of typical symptoms and positive results of auxiliary examinations, which make diagnosis difficult. In some cases, fever can be the only clinical manifestation. For the lymphoma patients presenting with persistent fever with a duration over 3 weeks, characteristics of fever including time of fever attack, fever type and effects of drugs may have significant value in the diagnosis, especially in the early stage of the disease or in rare cases.

We report a case of adenocarcinoma detected in the right pleural effusion of a 75-year-old woman. Investigations failed to reveal the site of the primary lesion, and the case was treated as primary unknown cancer. The pleural effusion disappeared after chemotherapy; however, as there was serious bone marrow suppression, the clinical course was observed at an outpatient clinic without chemotherapy. A search for the primary lesion was repeated, but it was not found. One year after first admission, a chest X-ray showed left pleural effusion. Adenocarcinoma was detected in the effusion and a tumor mass obtained from the pleural cavity. Ovarian cancer was diagnosed based on the histological, serological and MRI findings. Thus, this was a rare case of ovarian cancer in which the diagnosis was confirmed by repeated evaluation and in which the initial diagnosis had been primary unknown cancer with malignant pleural effusion only.
