\nEn cas d’inflammation, le nombre de cellules m\u00e9soth\u00e9liales augmente, leur taille est tr\u00e8s variable et elles peuvent \u00eatre multinucl\u00e9\u00e9es. Le diagnostic implique (1) l’application de crit\u00e8res individuels de b\u00e9nignit\u00e9 et (2) l’\u00e9tablissement de la pr\u00e9sence d’un continuum ininterrompu de tailles (de petite \u00e0 tr\u00e8s grande). Noter les noyaux augment\u00e9s en taille, petits nucl\u00e9oles multiples et espaces entre les cellules contigu\u00ebs (appel\u00e9s “fen\u00eatres”). Pr\u00e9sence de cellules inflammatoires dans le fond.<\/p>\n

A l’instar des \u00e9panchements pleuraux, les cellules m\u00e9soth\u00e9liales des \u00e9panchements p\u00e9riton\u00e9aux peuvent avoir des dimensions extr\u00eamement variables. Elles peuvent \u00e9galement \u00eatre m\u00e9lang\u00e9es \u00e0 des cellules inflammatoires et des histiocytes.<\/p>\n
