We present the case of a 55-year-old man who underwent transsacral local excision for a rectal submucosal tumor-like lesion suspected to originate from tuberculosis. The lesion, 2 cm in size, was found incidentally in the posterior wall of the lower rectum during anal fistulectomy. The lesion was apart from the primary crypt of the anal fistula. Barium enema and colonoscopy revealed a protuberant submucosal growth with a shallow depression of the overlying mucosa. Although computed tomography and magnetic resonance imaging showed a well defined round mass within the rectal wall, digital rectal examination suggested extramural origin. Since repeated endoscopic biopsies were negative, we selected the transsacral approach for excisional biopsy to achieve histological diagnosis. The lesion was confined to the rectal wall and the full-thickness rectal wall was excised. Histologically, a foreign-body granuloma with acute inflammation was the main component of the lesion. Caseating granulomas and Langhans' giant cells, consistent with tuberculosis, were also found. [ABSTRACT FROM AUTHOR] |
