Sarcoidosis is a multisystem disorder of unknown etiology characterized by the presence of non-caseating granulomas in the organs affected. Sarcoid arthropathy is a rare manifestation, and sacroiliitis is an unusual first manifestation of the disorder

Sir, Common variable immunode¢ciency (CVID), one of the most frequent of the primary speci¢c immunode¢ciencies, is a heterogeneous group of syndromes characterized by a de¢ciency in antibody synthesis associated with panhypogammaglobulinaemia and recurrent bacterial infections (1). The occurrence of non-caseating granulomas in di¡erent organs, including the skin, has been described previously. ...

A 77-year-old Japanese woman presented with asymptomatic abdominal lymphadenopathy. Soluble interleukin-2 receptor (sIL2R) and angiotensin-converting enzyme (ACE) levels were elevated, and a pathological examination of lymph-node biopsies revealed non-caseating granulomas, which was consistent with sarcoidosis. Fluorodeoxyglucose-positron emission tomography did not show a clear accumulation in...

Background Blau Syndrome (BS), a rare autoinflammatory disease characterized by non-caseating granulomas, is caused by gain-of-function mutations in NOD2. Crohn’s disease (CD) is associated with intestinal granulomas, and SNPs in NOD2. Emperipolesis, the ‘inside round about wandering’ of lymphocytes within other cells is a typical feature of Rosai-Dorfman disease, and seen occasionally in malig...

Sarcoidosis is a multisystemic inflammatory disease that commonly affects the lungs and lymphatic system and is characterized by the formation of non-caseating granulomas. Although the association between sarcoidosis and malignant diseases has been well described, it remains controversial whether this association is merely a coincidence or the consequence of a common pathophysiological mechanis...

Sarcoidosis is a granulomatous disorder mostly could involve intrathoracic structures. The gastric involvement is rare and the symptoms may be non-specific. We herein report a case of a 56-year-old female patient who was admitted due to chest tightness and discomfort. Computed tomography (CT) of the thorax revealed bilaterally nodular lesions in the lower lobes of the lung and pleural effusion ...

Clinically recognizable gastrointestinal (GI) system involvement with sarcoidosis is extremely rare. We present a case of a 51-year-old Caucasian male who was evaluated for abdominal pain, elevated liver enzymes, leukopenia, thrombocytopenia, severe peripheral arthralgias, and chronic watery diarrhea. He had a history of mediastinal and periaortic lymphadenopathy. Extensive laboratory work up f...

Sarcoidosis is a multi-organ disease of unknown etiology characterized by non-caseating granulomas. Here we report the case of a 78-year-old white male with a past medical history of diabetes mellitus, hypertension, and chronic kidney disease stage III with a baseline serum creatinine of 2.5 mg/dl. The patient had a prior admission history for acute kidney injury (AKI) attributed to dehydration...

Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world ́s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study is to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of t...

Sarcoidosis is a chronic and systemic disorder characterized by the formation of non-caseating granulomas. Very few cases of isolated gastrointestinal sarcoidosis have been reported, and even fewer, if any, report gastrointestinal sarcoidosis within multiple gastrointestinal sites concomitantly. We present a 42-year-old white man with chronic diarrhea and abdominal pain for more than 3 years. M...
