A 72-year-old man was followed as an outpatient at our hospital for 6 years after surgery for small cell carcinoma of left adrenal gland origin. Follow-up abdominal computed tomography showed a 6-cm mass in the left lower mesentery. The patient underwent open laparotomy. The histological diagnosis was sclerosing mesenteritis. The previous specimens of the left adrenal mass were then re-examined with a microscope, and panniculitis was found around the small cell carcinoma. Both lesions were histologically similar to IgG4-related disease (RD), but they did not completely meet the diagnostic criteria of IgG4-RD clinically or histologically.

Chylous ascites occur when the lymphatic flow is blocked or disrupted, causing a leakage of fluid into the peritoneal space. It can be caused by a number of etiologies and identifying the exact cause can be challenging. We present the case of a 77-year-old man who presented with chylous ascites.

Article Synopsis
- Sclerosing mesenteritis is a rare chronic condition that affects the mesenteric fat, involving inflammation and fibrosis without a clear cause, leading to variable symptoms, most commonly abdominal pain.
- Its diagnosis primarily relies on histological analysis, even though incidental findings have increased due to widespread CT imaging.
- The prognosis is generally good, but misdiagnosis is common, highlighting the need to consider it in cases of vague abdominal pain to prevent unnecessary treatments, though surgery might be required for severe cases like intestinal blockage.

Article Synopsis
- A 78-year-old male patient presented with persistent vomiting due to a rare case of metastatic urinary bladder cancer, which led to gastric outlet obstruction.
- Despite recent follow-up showing no disease recurrence, tests revealed duodenal stenosis and abnormal mesenteric fat swelling, initially misinterpreted as inflammation.
- A laparoscopic exploration confirmed peritoneal carcinomatosis, ultimately identifying urothelial cancer cells, highlighting the need for clinicians to think about metastatic bladder cancer in similar situations.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated disease with many important manifestations in hematopoietic and lymphoid tissue. IgG4 is the least naturally abundant IgG subclass, and the hallmark feature of IgG4-RD is markedly increased IgG4-positive plasma cells (with an IgG4 to IgG ratio >40%) in affected tissue, along with elevated polyclonal serum IgG and IgG4 in most patients. Histological diagnosis is essential, and other key features include storiform fibrosis, lymphoplasmacytic infiltrate, tissue eosinophilia, and obliterative phlebitis.

A 57-year-old male with a history of hypertension, diabetes mellitus, and dyslipidemia was found to have elevated carcinoembryonic antigen (CEA) levels during a routine health checkup, leading to an abdominal computed tomography (CT) scan. The scan identified a mesenteric mass with an irregular morphology. Subsequent blood tests indicated no signs of inflammation, and follow-up CEA levels normalized.
