CT Findings of Axillary Tuberculosis Lymphadenitis: A Case Detected by Breast Cancer Screening Examination.

We report the first description of CT findings of axillary tuberculous lymphadenitis confirmed by the pathological specimen. The breast cancer screening examination is one of the prime methods of detection of axillary tuberculous lymphadenitis. The most common site of axillary tuberculous lymphadenitis is the deep axilla. Screening mammography often fails to cover the whole axilla. The presence on the contrast-enhanced CT of unilateral multiple circumscribed dense nodes, some of which have large and dotted calcifications, might suggest tuberculous lymphadenitis in axillary region.

[A case of advanced gastric cancer diagnosed as stage IV responding to combined modality therapy and surviving for a long duration].

A 47-year-old woman was diagnosed as advanced gastric cancer of cardia(poorly-differentiated adenocarcionoma), with multiple para-aortic lymph node and liver metastasis, in March, 2005. We attempted neo-adjuvant chemotherapy with docetaxel(DOC), cisplatin(CDDP), and S-1(DCS). After 3 courses of DCS, we confirmed that the para-aortic lymph nodes and liver metastasis became small. Then, we were able to perform total gastrectomy, splenectomy, and D2 lymph node dissection. Additionally, we performed an intraoperative radiofrequency ablation to the scar of the liver metastasis. Histopathologically, we identified lymph node metastases in #1 and #16b1 pre. S-1 and DOC were administered as adjuvant chemotherapy. At seven years since the operation, the patient has shown no signs of recurrence. Combined modality therapy for advanced gastric cancer diagnosed with stage IV can be an effective treatment, so we hope that it will be established as a standard therapy.

Resected pleomorphic carcinoma of the gallbladder.

Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.
