Résumé

Prérequis : Les lipomes du colon sont des tumeurs adipeuses bénignes qui sont habituellement sous muqueuses. Les petites lésions sont asymptomatiques et peuvent être détectés de façon fortuite. Les lipomes géants peuvent être symptomatiques.
But : rapporter un cas de lipome géant colique symptomatique.
Observation : Il s’agit d’une femme âgée de 67 ans qui présente des douleurs abdominales persistantes pour lesquelles le transit baryté a montré une large masse polypoïde obstruant la lumière du colon transverse. La colonoscopie a objectivé une tumeur sessile à surface ulcérée réduisant la lumière colique. La malignité n’a pu être exclue et une résection chirurgicale a été proposée. L’étude anatomopathologique a conclu à un lipome colique. Douze mois plus tard, la patiente était asymptomatique.
Conclusion : L’éventualité diagnostique d’un lipome géant est importante à considérer afin de bien porter les indications thérapeutiques.
