Sarcoidosis is a multisystemic disorder of unknown etiology which is characterized by the formation of non-caseating granulomas in involved tissues. Cardiac involvement is one of the least common manifestations and it can occur at any point of time during the course of sarcoidosis. Here we present the case of 2 patients with known sarcoidosis who develop cardiac abnormalities in the absence of ...

Tumour necrosis factor alpha (TNFalpha) antagonists are an established therapeutic option in Crohn's disease and rheumatoid arthritis. In recently published studies these agents have been used with great success, but little is known about any side effects or long term consequences. They increase the frequency of infections with mycobacteria, where TNFalpha is thought to be an important host def...

Recurrence of testicular tumors in young males generally prompts rapid investigation and treatment. We report 3 patients with past histories of treated testicular cancer referred with radiographic evidence suggestive of intrathoracic metastases. In each case chest imaging demonstrated mediastinal/hilar lymphadenopathy. In one case pulmonary nodules were also identifi ed. In all three patients f...

Cutaneous metastatic Crohn’s disease (MCD) is a rare but challenging dermatologic manifestation of disease. It histologically defined as the presence non-caseating granulomas at skin sites separated from and non-contiguous to gastrointestinal tract. should be distinguished much more frequent contiguous cutaneous manifestations that present perianal or, less common, peristomal with direct extens...

Solitary pulmonary caseating granulomas (SPCGs) are a characteristic type of tuberculomas associated with infection with non-tuberculous mycobacteria (NTM) and other microbes; however, their significance remains unclear. The aim of the present study was to describe the clinical characteristics of patients with SPCGs in terms of diagnosis, presence of lung cancer and treatment status. A retrospe...

INTRODUCTION Sarcoidosis is recognized as a multiorgan disorder characterized by the presence of non-caseating granulomas in the involved tissues. It has been suggested that sarcoidosis might be due to the exposure to infectious or non-infectious agents in genetically susceptible individuals. In particular, Propionibacterium acnes and Mycobacterium tuberculosis have been considered causative mi...

Patients with sarcoidosis have a high risk of development of malignant lymphoma, and this association was coined the term "sarcoidosis-lymphoma syndrome". Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a distinct clinicopathological entity, and the stomach is the most common site. The occurrence of this type of lymphoma in the esophagus is extremely ra...

Treatment of tuberculosis is currently hindered by prolonged antibiotic regimens and the emergence of significant drug resistance. Alternatives and adjuncts to standard antimycobacterial agents are needed. We propose that a direct attack utilizing photosensitizers and light-based treatments may be effective in curtailing Mycobacterium tuberculosis in discrete anatomical sites in the most infect...

A 64-year-old woman visited our hospital for diarrhea that had persisted for 6 months. She had been treated for diabetes insipidus for 10 years. Her serum CA 19-9 and CEA level, and fecal tests were normal, and the tuberculin skin test was negative. Computed tomography (CT) (Fig. 1) showed hypertrophy of the colon (white arrows) and appendix walls (red arrow) and enlargement of many lymph nodes...
