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. 相似文献

Here, we describe a simple in vitro neural crest cell (NCC) migration assay and the effects of all‐trans‐retinoic acid (RA) on NCCs. Neural tubes excised from the rhombencephalic or trunk region of day 10.5 rat embryos were cultured for 48 h to allow emigration and migration of NCCs. Migration of NCCs was measured as the change in the radius (radius ratio) calculated from the circular spread of NCCs between 24 and 48 h of culture. RA was added to the culture medium after 24 h at embryotoxic concentrations determined by rat whole embryo culture. RA (10 μM) reduced the migration of cephalic NCCs, whereas it enhanced the migration of trunk NCCs, indicating that RA has opposite effects on these two types of NCCs. 相似文献
