1.1 Cutaneous sarcoidosis Sarcoidosis is a multisystem granulomatosis disease of unknown etiology, characterized pathologically by noncaseating granulomas in involved tissues1,2. It mainly involves the lungs but may also be associated with systemic manifestations3. The disease most commonly affects the lungs, lymph nodes, liver, spleen, phalangeal bones, parotid glands, eyes, and skin4. Skin in...

Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV) block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patie...

We present the case of a patient who presented with signs and symptoms associated with a Klatskin tumor. After endoscopic retrograde cholangiopancreatography (ERCP) and biopsy, she was found instead to have granulomatous infiltration of the extrahepatic biliary tree consistent with biliary sarcoidosis. The patient was treated successfully with systemic corticosteroids and azathioprine. She late...

GVHD: graft-versus-host disease HLA: human leukocyte antigen HSCTs: hematopoietic stem cell transplants INTRODUCTION Approximately 25,000 allogeneic hematopoietic stem cell transplants (HSCTs) are performed annually. Cutaneous complications are common and include a spectrum of acute and chronic graft-versus-host disease (GVHD). Mechanisms implicated in the rare development of sarcoidosis after ...

The relation between non-specific delayed cutaneous hypersensitivity and bird fancier's lung was investigated in 13 patients with the disorder. They were compared with 50 subjects who had no reason to have decreased non-specific delayed cutaneous hypersensitivity (control group) and 34 patients with pulmonary sarcoidosis. In addition, 13 patients with bird fancier's lung (11 of the original gro...

BACKGROUND In recent years we have observed with increasing frequency granulomatous papular lesions involving the knees, for which we proposed the term papular sarcoidosis of knees. OBJECTIVES To evaluate the clinicopathological features of papular sarcoidosis of the knees. METHODS Patients with papular lesions of the knees and histopathologically sarcoid granulomas were included in the stu...
