A 63-yr-old woman, known case of ulcerative colitis, was diagnosed with sclerosing cholangitis 2 years back. She was admitted for investigation of abdominal discomfort, fatigue with elevated alkaline phosphatase and deranged liver function test. Imaging studies (computerised tomography and magnetic resonance imaging) demonstrated a normal biliary tree with focal hepatic lesion which was showing...

In patients with malignancy, the common etiologies of granuloma formation are tumor related sarcoid reaction, sarcoidosis, tuberculosis and other granulomatous diseases. Often, the finding of granulomas in malignant patients may obscure the primary malignancy or may mislead towards treatment of infectious and other etiologies. Hence, their proper recognition and necessary follow up is needed to...

Mast cells and eosinophils actively participate in tissue repair and are prominent components of Schistosoma mansoni granulomas. Since pentoxifillyne (PTX) is an immunomodulatory and antifibrotic substance, we aimed to characterize, by morphological techniques, the effect of this drug on fibrosis developed inside murine hepatic schistosomal granulomatous reaction, beyond the quantification of e...

BACKGROUND Bartonella henselae (B. henselae) is considered a rare cause of granulomatous hepatitis. Due to the fastidious growth characteristics of the bacteria, the limited sensitivity of histopathological stains, and the non-specific histological findings on liver biopsy, the diagnosis of hepatic bartonellosis can be difficult to establish. Furthermore, the optimal treatment of established he...

Burkitt lymphoma (BL) is a highly aggressive subtype of non-Hodgkin lymphomas (NHL). Lymphoma related granulomatous reaction rarely occurs in sporadic BL. Herein, we describe the first case of HIV related Burkitt lymphoma with florid granulomatous reaction. A 41-year-old HIV-positive Chinese male presented lymphadenopathy in the right cervical region for 3 months. The enlarged lymph node biopsi...
