Duodenal tuberculosis with gastric outlet obstruction: a case report of successful diagnosis and treatment, with review of literature.

Background: Duodenal tuberculosis (TB) is extremely rare, and its diagnosis is challenging owing to the lack of specific symptoms and radiological or endoscopic findings. When it leads to gastric outlet obstruction (GOO), diagnosing it accurately and providing appropriate treatment is crucial. However, this is often overlooked.

[A Case of Gastric Neuroendocrine Carcinoma with Rapidly Increasing Liver Metastasis].

A 53-year-old woman, who had been operated with Bt plus Ax plus Ic for right breast cancer 2 years before, revealed an isolated hepatic metastasis at the S4 edge on follow-up computed tomography. The surgical approach is not recommended for distant metastases from breast cancer because of the lack of survival benefits according to the breast cancer guidelines. Nevertheless, the operation could be performed safely and easily for this patient owing to the location and size of the tumor.

A new method to optimize resection area using a radiation treatment planning system and deformable image registration for breast-conserving surgery after neoadjuvant chemotherapy.

Background: We devised a breast-conserving surgery (BCS) utilizing a new image-processing and projection technique using a radiation treatment planning system (RTPS) and deformable image registration (DIR) for patients with breast cancer after neoadjuvant chemotherapy (NAC). RTPSs and DIR are commonly used in planning radiation treatment. The purpose of this pilot study was to evaluate the feasibility of our procedure.

We report 4 patients with occult breast cancer(OBC)who underwent breast conserving therapy(BCT)after neoadjuvant chemotherapy(NAC). All patients complained of axillary tumor and were diagnosed by core needle biopsy. Pathological examination of the axillary lymph nodes proved that 3 cases were adenocarcinomas and 1 case was squamous cell carcinoma, but imaging studies could not depict any primary lesions in the breast and other organs.
