Mesoappendiceal and periappendiceal lesions

A retrospective review study of 4371 appendectomy specimens over four years showed eight cases (0.18%) with a variety of mesoappendiceal and periappendiceal lesions. Most (five cases) were benign incidental pathologic findings (lymph nodes with reactive follicular hyperplasia, ectopic decidua, infarcted epiploica and peritoneal cyst), one case was a rare occurrence (inflammatory fibroid tumor), and few others (two cases) were clinically important findings (tuberculosis and schistosomiasis). They were more commonly found in young adult males with a male to female ratio of 7:1.
