Sarcoidosis is a multisystemic disorder of unknown cause characterized by the formation of immune granulomas in involved organs. It is an ubiquitous disease with incidence (varying according to age, sex, race and geographic origin) estimated at around 16.5/100,000 in men and 19/100,000 in women. The lung and the lymphatic system are predominantly affected but virtually every organ may be involved. Other severe manifestations result from cardiac, neurological, ocular, kidney or laryngeal localizations. In most cases, sarcoidosis is revealed by persistent dry cough, eye or skin manifestations, peripheral lymph nodes, fatigue, weight loss, fever or night sweats, and erythema nodosum. Abnormal metabolism of vitamin D3 within granulomatous lesions and hypercalcemia are possible. Chest radiography is abnormal in about 90% of cases and shows lymphadenopathy and/or pulmonary infiltrates (without or with fibrosis), defining sarcoidosis stages from I to IV. The etiology remains unknown but the prevailing hypothesis is that various unidentified, likely poorly degradable antigens of either infectious or environmental origin could trigger an exaggerated immune reaction in genetically susceptible hosts. Diagnosis relies on compatible clinical and radiographic manifestations, evidence of non-caseating granulomas obtained by biopsy through tracheobronchial endoscopy or at other sites, and exclusion of all other granulomatous diseases. The evolution and severity of sarcoidosis are highly variable. Mortality is estimated at between 0.5-5%. In most benign cases (spontaneous resolution within 24-36 months), no treatment is required but a regular follow-up until recovery is necessary. In more serious cases, a medical treatment has to be prescribed either initially or at some point during follow-up according to clinical manifestations and their evolution. Systemic corticosteroids are the mainstay of treatment of sarcoidosis. The minimal duration of treatment is 12 months. Some patients experience repeated relapses and may require long-term low-dose corticosteroid therapy during years. Other treatments (immunosuppressive drugs and aminoquinolins) may be useful in case of unsatisfactory response to corticosteroids, poor tolerance and as sparing agents when high doses of corticosteroids are needed for a long time. In some strictly selected cases refractory to standard therapy, specific antiTNF-alpha agents may offer precious improvement. Some patients benefit from topical corticosteroids.

We report a case of acute Epstein-Barr virus (EBV) infection in which the clinical syndrome and pattern of F-18-2-fluoro-2-deoxy-D-glucose (FDG) uptake mimicked malignant lymphoma. A 53-yr-old man presented with 2 wk of high fevers, night sweats, sinus congestion and severe fatigue. The patient was treated for 1 wk with broad-spectrum antibiotics for acute sinusitis without any improvement. Persistence of fevers and presence of abnormal lymphadenopathy seen on the abdominal computed tomography (CT) were concerning lymphoma with B symptoms. FDG positron emission tomography (PET) showed avid FDG uptake in numerous abdominal/pelvic nodes, liver, spleen and bone marrow. These findings were highly suspicious for lymphoma. Patient underwent a pelvic lymph node biopsy which showed large granular lymphocytes that were predominantly T cells. Bone marrow biopsy showed diffuse infiltration with plasmocytoid cells that were not kappa lambda restricted. Additional diagnostic workup became available showing positive EBV IgM titers and negative IgG levels indicating acute infectious mononucleosis. Lymph node biopsy stained positively with EBV-encoded RNA. We concluded that patient's abnormal FDG PET was most likely secondary to acute EBV infection. After 2 months, follow-up FDG PET/CT showed marked improvement in lymphadenopathy and decreased hypermetabolic activity in the liver and spleen. Other than EBV, there are many other FDG-avid non-malignant conditions that may lead to false-positive PET scans. FDG accumulates in inflamed and infected lesions with increased glucose metabolism. This case underscores the importance of maintaining a broad differential and restricting use of PET scans for staging.

Wegener's Granulomatosis (WG) is a rare, Multisystem disease of the medium and small sized arteries and veins. It most commonly involves the upper respiratory tract, lungs, and kidneys and often presents as chronic fatigue, upper respiratory infection, sinusitis, and otitis media. Symptoms can include fever, weight loss and fatigue, though these are not usually the primary presenting complaints. development of the disease is highly skewed across ethnicities, with up to 98% of cases being reported in caucasians. We present the case of a 56-year-old African-American male who presented primarily with complaints of uncontrollable fever of unknown origin (FUO) for past two weeks with accompanying sore throat, nasal congestion, night sweats, malaise, and unexplained weight loss of 10 pounds over the past month. Treatment with antibiotics for one week prior to admission showed no relief of symptoms. Chest x-ray showed focal course markings in the right upper lobe. Urinalysis revealed microscopic hematuria and leukocyturia. Chest and abdominal CT scans revealed a right lower lobe pulmonary nodule and heterogeneous areas of enhancement in the spleen. Head CT revealed right mastoid opification. Labs revealed proteinase-3 antibody titer > 100, which is characteristic of WG. Steroids and cyclophosphamide were started with relief of presenting symptoms. Renal biopsy showed pauci-immune P-ANCA associated crescentic and focally necrotizing glomerulonephritis and vascilitis. This case is unique in that the patient presented with primary complaint of FUO. WG should be considered as a rule-out in cases of uncontrollable FUO, even if none of the classic triad of symptoms is present. Though rare, WG should be considered in cases involving non-Caucasian patients.

Patients who have non-Hodgkin's lymphoma or Hodgkin lymphoma most often present for medical attention because of signs or symptoms referable to enlarged lymph nodes or other disease-related symptoms (such as fevers, night sweats or fatigue). Less often, enlarged lymph nodes or splenomegaly may be incidental findings during evaluation for other medical issues. Determination of the extent of disease and accurate assessment of responses are necessary for appropriate management. Newer technologies have improved the ability to evaluate patients and to conduct clinical trials, leading to more effective therapies. This article addresses the advances in staging and evaluation of patients who have lymphoma, specifically examining the use of positron emission tomography.

We present an unusual case of supraclavicular benign hibernoma in a 12-year-old girl who presented with chest discomfort, night sweats, shortness of breath, fatigue, and pruritus. This is the first case of hibernoma being reported as symptomatic in the world literature. Symptoms persisted for 1 year till excision biopsy. Biopsy of supraclavicular lump revealed a hibernoma. Symptoms resolved within 2 months of excision and 1-year follow-up showed no recurrence of symptoms or supraclavicular swelling.

Quality of life (QoL) in patients with myelofibrosis (MF) is severely compromised by severe constitutional symptoms (i.e. fatigue, night sweats, fever, weight loss), pruritus, and symptoms from frequently massive hepatosplenomegaly. Given that no current instrument of patient reported outcomes (PRO) exists that covers the unique spectrum of symptomatology seen in MF patients, we sought to develop a new PRO instrument for MF patients for use in therapeutic clinical trials. Utilizing data from an international Internet-based survey of 458 patients with MF we created a 20-item instrument (MFSAF: Myelofibrosis Symptom Assessment Form) which measures the symptoms reported by >10% of MF patients and includes a measure of QoL. We subsequently validated the MFSAF in a prospective trial of MF patients involving patient and provider feedback, as well as comparison to other validated instruments used in cancer patients. The MFSAF results were highly correlated with other instruments, judged comprehensive and understandable by patients, and should be considered for evaluation of MF symptoms in therapeutic trials.

We report the first known case of both Noonan syndrome and Whipple's disease occurring in the same patient. A 36-year-old female with history of Noonan syndrome developed fatigue, anorexia, arthritis of the knees and hands with a diffuse hyperpigmented rash, night sweats, and an unintentional fifteen pound weight loss over 4 mo. Small bowel enteroscopy demonstrated mild edematous yellowish mucosa without friability. Random small bowel biopsies revealed extensive periodic acid-Schiff positive material within the foamy macrophages. She was treated with a 12 mo course of trimethoprim-sulfamethoxazole DS with clinical improvement to baseline status.

Brucellosis which is a endemic in Turkey, is a systemic infection which can affect any organ or system in the body. Since signs and symptoms of brucellosis resemble many other diseases, misdiagnosis and related increase in morbidity rate, are common. In this report, a case of brucellosis complicated with endocarditis, pyelonephritis, sacroileitis and thyroiditis, was presented. The case was a 32-years-old female patient in whom the diagnosis of brucellosis was delayed by 12 months since it was not taken into consideration during the clinical follow-up of the patient in various clinical centers. The patient was admitted to our center with the complaints of fever, headache, back pain, night sweats, fatigue, loss of appetite, weight loss, dysuria and polyuria. The patient had a history of consumption of raw milk and dairy products. Positive Brucella tube agglutination test (1/1280) and isolation of Brucella spp. in blood cultures led to the diagnosis of brucellosis. Sacroileitis was diagnosed upon pain on right hip joint movements, pain and restriction at the same joint in FABER test. The detection of vegetation during echocardiography, cardiac murmur during physical examination and the determination of increased ESR and CRP levels led to the diagnosis of endocarditis. Abdominal ultrasonography and urinalysis results (hematuria, proteinuria and pyuria) revealed pyelonephritis and increased free T3 and T4, decreased TSH and positive anti-thyroid autoantibodies (anti-TG, anti-TPO) revealed thyroiditis. Treatment was started with combination of rifampisin (1 x 600 mg/day) and doxycycline (2 x 100 mg/day). After the diagnosis of endocarditis, trimethoprim-sulfamethoxazole (3 x 960 mg/day) and streptomycin (1 x 1 g/day) were added to the treatment. Valve replacement surgery was planned, however, the patient didn't accept surgical intervention and antimicrobial treatment continued with streptomycin for 21 days and other antibiotics for six months. The patient exhibited significant improvement after the medical treatment. Although sacroileitis is a frequent complication of brucellosis, endocarditis, thyroiditis and pyelonephritis are among the rare complications. In cases of brucellosis with multiorgan involvement including endocarditis, successful results may be achieved by aggressive antimicrobial treatment. In endemic areas, brucellosis should always be taken into consideration in patients with fever of unknown origin and multisystem involvement.

A 53-year-old diabetic woman with the diagnosis of myelodysplastic syndrome was admitted to our hospital with symptoms of anorexia, malaise, fatigue, night sweats, and weight loss. The radiological evaluation revealed waxing and waning pulmonary nodules. A diagnosis of pulmonary tuberculosis was reached by pathologic examination of a wedge biopsy. We did not find a similar case in the literature. Clinicians should keep tuberculosis in mind as a possible etiology of waxing and waning pulmonary nodules.

We report 2 patients with epididymo-orchitis, caused by Brucella melitensis, accompanied by severe delay of diagnosis. In 1 patient the correct diagnosis was only suspected after his wife had been diagnosed with brucellosis. Our cases illustrate that diagnosing brucellosis can be difficult in nonendemic areas, especially when physicians are unfamiliar with it. Important clues pointing to brucellosis as cause of epididymo-orchitis are a travel history to endemic areas, unresponsiveness to empiric antibiotic treatment, and a preceding period of episodic subfebrile temperature, night sweats and fatigue. Serology is the diagnostic test of choice because it is faster and more sensitive than blood cultures. Delay of diagnosis may lead to serious complications. Therefore, alertness for brucellosis is warranted, also, if not especially, in nonendemic areas.
