Introduction: Although the association between cancer and sarcoidosis or sarcoid reaction is known, sarcoid reaction associated with Merkel cell carcinoma is rare. Case presentation: We report the case of a 57-year-old Japanese woman with Merkel cell carcinoma in the inguinal area associated with sarcoid reaction. Fluorodeoxyglucose positron emission tomography demonstrated elevated fluorodeoxy...

The equine sarcoid affects horses of all ages, types, and colours without obvious sex predilection and is commonly encountered worldwide. It is by far the commonest equine skin neoplasm (Jackson, 1936; Thomsett, 1979; Pascoe and Summers, 1981; Genetzky, Biwer and Myers, 1983; Marti, Lazary and Gerber, 1993; Broström, 1995). Although the sarcoid has been recognised for centuries (Erk, 1976), it ...

•Preoperative diagnosis of sarcoid reactions is important to avoid overtreatments.•Sarcoid reactions could act as a favorable prognostic factor in ovarian cancer.

Background Cardiac involvement is a major risk factor for sudden death in patients with systemic sarcoidosis. Pathologically, cardiac sarcoid lesions can be classified as early (mainly lymphocytic, similar to lymphocytic myocarditis), intermediate (active granulomatous), and late phase (primarily scar). These pathological processes can affect the myocardial extracellular space volume (ECV) in c...

A 77-year-old woman was admitted to our hospital because of a mass lesion in the left lung. The tumor was pulmonary carcinoid associated with sarcoid reactions in the regional lymph nodes and scattered in the resected lung parenchyma. Pulmonary carcinoid with sarcoid reactions is extremely rare. This appears to be the first case report in which tumor-related sarcoid reactions were studded withi...

While case reports have appeared in radiology literature previously about sarcoid involvement of the tibia, the spine and the pelvis, there are no case reports describing involvement of the humerus. We report a case of sarcoid involvement of the humerus secondary to pulmonary sarcoidosis. While the imaging findings are non-specific, they follow the pattern of imaging characteristics described i...

BACKGROUND Propionibacterium acnes was found in lungs and lymph nodes of patients with sarcoidosis and may induce hypersensitivity type granuloma formation. Data regarding the immune response to P. acnes of European sarcoid patients are scarce. METHODS We assessed the total IgG and IgA amount and specific antibodies to P. acnes and to Staphylococcus aureus, serving as a control, in BAL fluid ...

BACKGROUND This study aims to analyze the structure and quantities of cellular elements in sarcoid granulomas. METHODS We investigated 34 transbronchial lung biopsy samples obtained from 34 sarcoid patients. The quantity and composition of the cellular elements inside a granuloma were determined by the quantitative stereometry method, employing the numerical density as a stereological method....

From 1992-2004, single lung transplantation has been performed in seven patients with end-stage pulmonary sarcoidosis at the Danish National Centre for Lung Transplantation. The objective was to assess whether recurrent sarcoid granulomas in the lung graft are derived from recipient or donor immune cells. Three patients had sarcoid recurrence in the lung graft, but none had clinically overt ext...
