Exempel på granuloma

• Occasionally, the presence of larvae stimulates the granuloma formation responsible for the deleterious effects of ocular toxocariasis.

• Diagnosis is performed by histological examination of the tissue and the characteristic lesion is a granuloma surrounding a larva.

• They are also postulated to stimulate other cells for granuloma formation.

• The reason for partial recovery is that the healing process produces scarring and granuloma formation, known as neuroma.

• By 60 days post-infection eggs were regularly seen and livers contained egg granulomata.

• Histological examination of the resected aneurysm revealed myocardium which was almost totally replaced by dense fibrous tissue and numerous caseating granulomata.

• The granulomas and necroses were usually located in the tissue adjacent to the peritoneum.

• In the late stages (cutaneous scars), fibroblasts proliferated at the periphery of and finally invaded the granulomas with fibrotic substitution (data not shown).

• Alterations consisted of thickened air sac walls (fig. 1e), lesions or granulomata at the site of worm attachment, sometimes involving underlying tissues.

• The lung biopsy showed numerous focal granulomata full of histocytes, lymphocytes, polymorphs and eosinophils with infrequent giant cells.

• The infant was extubated after surgical excision of laryngeal granuloma and discharged 1 month later.

• When many females were present, however, fibrous changes with granulomata surrounding eggs usually occurred in the lungs.

• According to findings, cases were grossly classified as noninfectious (lymphoproliferative) and chronic infectious (caseating granulomata).

• Lesions appeared as small firm grey-white nodules characteristic of schistosome egg granulomas.

• Sections of liver and lung from several animals showed the characteristic pathology associated with schistosomal egg granulomata.
