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...

  Chronic granulomatous disease (CGD) is a rare inherited disorder characterized by inability of phagocytes to generate oxygen radicals needed for intracellular killing of phagocytic microorganisms. We report a 2.5-year-old Iranian female with multiple liver abscesses. She was admitted in surgical ward because of abdominal pain and fever for one month duration that had no response to conventio...

BACKGROUND Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolut...

Dermal granulomatous inflammation was identified immediately adjacent to seven (77%) of nine atypical fibroxanthomas arising in sun damaged skin. Concomitant elastophagocytosis was observed in five (56%) of these seven patients. Similar inflammation with elastophagocytosis was found in association with only two (6%) of 36 epithelial tumours arising on the same background (10 basal and 10 squamo...

Acute inflammation is traditionally described as the influx of polymorphonuclear leukocytes (PMNs) followed by monocyte-derived macrophages, leading to resolution. This is a classic view, and despite subpopulations of lymphocytes possessing innate immune-regulatory properties, seldom is their role in acute inflammation and its resolution discussed. To redress this we show, using lymphocyte-defi...

Objective(s) Air pouch is a well-established inflammatory model in which fluid extravasations; leukocyte migration, angiogenesis and other parameters involved in the inflammatory response can be measured. In this study, the influence of gender on inflammatory parameters has been examined in the air pouch model. Materials and Methods To induce air pouch, adult male and female Wistar rats were...

Etiopathogenesis of pulmonary granulomatous lesions can be very varied. Pathologists find pulmonary granulomatous lesions in autopsies frequently. Diagnostics of pulmonary granulomatous lesions is based on anamnesis data, clinical examinations and morphological changes. In some cases, especially in long-term ill patients, morphological finding remains the only way to explain the case. We provid...
