[Two Resected Cases with Superficial Basaloid Squamous Carcinoma of the Esophagus].

We report 2 resected cases of superficial type basaloid squamous cell carcinoma of the esophagus. Case 1 is a 67-year-old man who underwent endoscopic submucosalresection for superficialel evated type esophagealcancer of the middle thoracic esophagus. Because the pathological diagnosis of the resected specimen was basaloid squamous cell carcinoma invading to the submucosal layer with lymphatic vessel invasion, esophagectomy was indicated. The resected specimens showed no tumor in the esophagus. However, metastasis was diagnosed in the dissected mediastinall ymph nodes. Left cervicall ymph node recurrence was detected 1 years 10 months after surgery, and lymphadenectomy was performed after irradiation therapy. He survived 4 years after the first operation. Case 2 is a 60-year-old man who underwent esophagectomy for superficial elevated type adenosquamous cell carcinoma with submucosal invasion. The pathological diagnosis revealed basaloid squamous cell carcinoma with submucosal invasion. The pathological diagnosis revealed basaloid squamous cell carcinoma invading the submucosal layer with lymphatic and blood vessel invasion. The patient died of recurrent disease in the lungs and liver 3 months after surgery. Although these 2 cases were superficial type esophageal basaloid squamous cell carcinoma, both had severe vessel invasion and lymph node metastasis. In basaloid squamous cell carcinoma, adjuvant therapies are needed after surgery, even if the lesion is diagnosed as superficial type. Multimodality treatment is needed for greater survival benefit.

Postoperative enteroenteric intussusception in patients with Crohn's disease: report of two cases.

Postoperative enteroenteric intussusception is a rare complication in adult patients with Crohn's disease. We treated two patients with Crohn's disease accompanied by an ileal obstruction, each of whom underwent an elective resection. In both, the upper left quadrant of the abdoment became progressively distended following ileocecal resection and each required surgical treatment after diagnosis of postoperative enteroenteric intussusception by abdominal computed tomography scanning, as the intussusception could not be reduced by conservative treatment. There were no Crohn's lesions found in the intussuscepted specimens, and the condition was thought to have been caused by a segment of thickened and fibrotic intestine that had developed because of long-standing bowel dilatation from obstructive Crohn's lesions. In one of the patients, the intussusceptum was irreducibly incarcerated and required a resection, whereas it was able to be manually reduced in the other.
