A Rare Case of Chest Wall Castleman's Disease with Calcification.

Castleman's disease with calcification of the chest wall is very rare, and there have been few reports of such cases to date. A 57-year-old woman was referred to our hospital for a tumor with calcification on her left lateral chest wall, which was detected on chest computed tomography. Findings of her chest magnetic resonance imaging suggested schwannoma or a solitary fibrous tumor, and therefore, we performed surgery for diagnostic and therapeutic purposes.

Leiomyosarcoma of the transverse colon with lymph node metastasis and malignant transformation: a case report.

Background: The concept of GIST was established in 1998, clearly differentiating between gastrointestinal leiomyosarcoma and GISTs among gastrointestinal mesenchymal tumors. Lymph node metastasis is extremely rare in true gastrointestinal leiomyosarcoma, and there are no reports of malignant transformation from leiomyoma.

Case Presentation: The patient was an old woman who had undergone endoscopic mucosal resection for an Is polyp on the left side of the transverse colon at the age of 73.

[A Case of Synchronous Liver Metastasis of Ascending Colon Cancer with Pathological Complete Response to S-1/Oxaliplatin (SOX) and Bevacizumab].

A 77-year-old man was diagnosed with ascending colon cancer with synchronous liver metastasis. Per our policy we first only performed a right hemicolectomy (pSSN2H2M0, stage IV). We then planned S-1 and oxaliplatin (SOX) plus bevacizumab (Bmab) chemotherapy as a neoadjuvant for the resection of liver metastasis.
