| pyogenic granuloma | Granuloma pyogenicum, an acquired small rounded mass of highly vascular granulation tissue, frequently with an ulcerated surface, projecting from the skin or mucosa; histologically, the mass resembles a capillary haemangioma. Synonym: granuloma telangiectaticum. (05 Mar 2000) |

| granuloma, pyogenic | A usually solitary polypoid capillary haemangioma of the skin and gingival or oral mucosa, often associated with trauma or local irritation, representing a vasoproliferative inflammatory response. It presents as a small erythematous papule that enlarges and may become pedunculated and may become infected and ulcerate with accompanying purulent exudate. The haemangioma without suppuration is called angiogranuloma. Pyogenic granuloma is not a granuloma: the name refers to the mass of inflamed, highly vascular granulation tissue. (12 Dec 1998) |

| recurrent pyogenic cholangitis | Repeated attacks of cholangitis, commonly noted among Asians living in Asia, associated with the presence of multiple intrahepatic and extrahepatic bile duct stones and strictures. (05 Mar 2000) |
| pyogenic | <microbiology> Producing pus, pyopoietic which is the liquid inflammatory product made up of cells and a thin fluid called liquor puris Origin: Gr. Gennan = to produce (18 Nov 1997) |
| pyogenic arthritis | Acute inflammation of synovial membranes, with purulent effusion into a joint, due to bacterial infection; the usual route of infection is hemic to the synovial tissue, causing destruction of the articular cartilage, and may become chronic, with sinus formation, osteomyelitis, deformity, and disability. Synonym: purulent synovitis, pyarthrosis, pyogenic arthritis, suppurative synovitis. (05 Mar 2000) |
| pyogenic bacterium | A bacterium that causes a pyogenic infection, such as the pyogenic cocci (staphylococci, streptococci, pneumococci, meningococci) and Haemophilus influenzae. (05 Mar 2000) |
| pyogenic fever | <microbiology> The invasion of bloodstream by pyogenic organisms. Origin: Gr. Haima = blood (18 Nov 1997) |
| pyogenic infection | Infection characterised by severe local inflammation, usually with pus formation, generally caused by one of the pyogenic bacteria. (05 Mar 2000) |
| pyogenic membrane | A layer of pus cells lining an abscess cavity which have not yet autolyzed. Synonym: prophylactic membrane. (05 Mar 2000) |
| pyogenic pachymeningitis | Suppurative inflammation of the dura, often spreading from a neighboring osteomyelitis. (05 Mar 2000) |
| pyogenic salpingitis | A form of acute salpingitis usually occurring with puerperal infection. (05 Mar 2000) |
| actinic granuloma | An annular eruption on sun-exposed skin which microscopically shows phagocytosis of dermal elastic fibres by giant cells and histiocytes. Synonym: Miescher's granuloma. (05 Mar 2000) |
| amoebic granuloma | A nodular, tumour-like focus of proliferative inflammation sometimes developing in chronic amoebiasis, especially in the wall of the colon. Synonym: amoebic granuloma. Origin: amoeba + G. -oma, tumour (05 Mar 2000) |
| apical granuloma | Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment. (12 Dec 1998) |
| beryllium granuloma | A sarcoid-like granulomatous reaction to exposure to inhaled beryllium, or skin cuts by fluorescent lamps. (05 Mar 2000) |
| bilharzial granuloma | A granulomatous lesion formed around schistosome eggs embedded in tissues in cases of schistosomiasis (bilharziasis); typically these granulomata are found in intestinal tissues (Schistosoma japonicum or S. Mansoni infection), bladder tissue (S. Haematobium), and hepatic tissue (all human schistosomes). Synonym: bilharzial granuloma. (05 Mar 2000) |
