BACKGROUND Sarcoidosis is a multisystem granulomatous inflammatory disease that is induced by infectious or noninfectious environmental antigens in a genetically susceptible host. Tuberculosis and sarcoidosis are two diseases with similar clinical and pathologic findings. The link between these two diseases has been extensively studied. OBJECTIVE Herein we describe a case of sarcoidosis assoc...

WHAT DOES THE PATHOLOGY OF SARCOID GRANULOMA TELL US? sarcoidosis patients, achieving remissions both of cutaneous lesions and pulmonary manifestations of the disease. Similarities between Tuberculosis and Sarcoidosis have caused researchers to suspect a mycobacterial Finally, Moller and Chen presented persuasive pathogenesis since, at least, Guy Scadding's arguments [6] based, in part, on comm...

Immunological abnormalities in sarcoidosis have been previously described. Cutaneous anergy to a wide variety of antigens first prompted the suggestion that the underlying defect may be of importance in the aetiology or pathogenesis of the disorder. The thymus derived lymphocytes appear to be particularly affected, and both quantitative and qualitative in vitro defects have been described in th...

sarcoidosis of the skin which were initially treated as leprosy based on the histopathological features. Histological study in one patient showed perineural and perivascular granuloma adding on to the diagnostic confusion. It is very important for the clinicians to consider sarcoidosis as a possible diagnosis in a patient with clinical features that are not typical of leprosy. Histopathology al...
