Tubercles

Granulomas – treatment and types

Granulomas – treatment and types Granulomas are small nodular clusters of cells with typical dimensions of 1-2mm. Their formation is a long ongoing response to the slow destroying pathogens by the cells of monocyte-macrophage system. Granulomas...
Miliary tuberculosis of the lungs

Miliary tuberculosis of the lungs

Miliary tuberculosis of the lungs   Peribronchial are found  unevenly scattered granulomas the size of the millet grain (milium). In some of them dominate a central caseous necrosis area, and in others the necrosis is scant and surrounded...
Tuberculosis leptomeningitis

Tuberculosis leptomeningitis

Tuberculosis leptomeningitis   Leptomeninges of the dorsal surface of the brain are swollen, blood vessels are with thickened walls (Aw) –tuberculotic vasculitis (endarteriitis which can be complicated with thrombosis). The fibrinous...
Grave’s disease

Grave’s disease – pathology and pictures

Grave’s disease – pathology and pictures     Thyroid gland shows nodular structure. Colloid is highly diluted, pale with plenty  optical empty  („resorbtive”) vacuoles at the periphery, at some place – ‘garland’-...
Chronic pyelonephritis

Chronic pyelonephritis – pathology and pictures

Chronic pyelonephritis – pathology and pictures   Histological triad: 1. In interstitium mostly on the border  of cortex/medulla,  are found focal infiltrations of lymphocytes and plasma cells. 2. Renal tubules are dilated and...
Acute pyelonephritis

Acute pyelonephritis

Acute pyelonephritis   Renal cortex is focally destroyed by segmented leukocytic infiltration  among which can be found bacterial colonies. Glomeruli even in close proximity to the abscesses, stay long time unaffected. In tubules are...
Mesangiocapillary glomerulonephritis

Mesangiocapillary glomerulonephritis

Mesangiocapillary glomerulonephritis   The glomeruli are enlarged, markedly  lobulated and ‘rich’ in cells due to proliferation of mesangial cells (more than 2 cells in a plane section) and accumulation of basement membrane-like...
Crescentic glomerulonephritis

Crescentic glomerulonephritis

Crescentic glomerulonephritis   In 80% of the glomeruli are found extra capillary ‘crescents’,  which engage 2/3 of the circumference of Bauman’s capsule. The process starts intra-capillary as a result of the anti- basement membrane...
Chronic cholecystitis

Chronic cholecystitis – pathology and pictures

Chronic cholecystitis – pathology and pictures   Chronic cholecystitis can be presented  with hypertrophy or atrophy of bladder mucosa. The wall is focally infiltrated by lymphocytes and plasma cells, and in a state of exacerbation...
Acute duodenal ulcer

Acute duodenal ulcer

Acute duodenal ulcer   Acute duodenal ulcer is a mucosal defect which unlike the ‘erosion’ penetrates through muscularis mucosae to reach muscularis propria (MP). Glands in the area of the ulcerated edges are destroyed. In the edges...
