Cowden syndrome (CS) is an autosomal dominant syndrome characterized by the development of hamartomas and an increased cancer risk. Most CS patients harbor mutations in the phosphatase and tensin homolog (PTEN) gene. We herein report a 70-year-old patient with CS who presented with lower extremity weakness caused by multiple thoracic dural arteriovenous fistulas. ⋯ However, spinal dural arteriovenous fistulas (AVFs) are extremely rare. Furthermore, in our case, the number of AVFs increased, and both lower limbs became flaccid four months after embolization. Therefore, we suggest that physicians carefully observe the changes in symptoms for prolonged periods after embolization.

A 59-year-old woman was diagnosed with a pancreatic neuroendocrine tumor (P-NET; Grade 3, Ki67: 25%) with multiple liver and lymph node metastases and started chemotherapy with streptozosin (500 mg/m2/day) in combination with lanreotide acetate (120 mg). After six courses of (daily) streptozosin, the patient had progressive disease, as assessed by computed tomography (CT), and peptide receptor radionuclide therapy (PRRT) was started as second-line treatment. As PRRT was remarkably successful and the tumor shrank, surgery was performed to resect the primary pancreatic tumor, liver metastases, and lymph node metastases. CT evaluation performed six months after the surgery showed a complete response.

A 71-year-old woman diagnosed with unresectable locally advanced pancreatic cancer was initially treated with gemcitabine and nab-paclitaxel as first-line therapy. The tumor exhibited no significant progression; however, after 12 cycles, the patient developed drug-induced interstitial pneumonia, leading to the discontinuation of gemcitabine and nab-paclitaxel therapy. ⋯ Although rarely reported, S-1-induced hyperammonemia is potentially a significant adverse effect. Here, we herein report the case of a patient with pancreatic cancer.

Objective This study assessed the impact of dietary therapy and reduced body weight on the loss of skeletal muscle in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). Methods This was a single-center retrospective observational study. We enrolled 129 patients with MASLD who had undergone dietary therapy at our facility. ⋯ A logistic regression analysis revealed that type 2 diabetes mellitus (T2DM) was an independent variable related to severe skeletal muscle loss (odds ratio, 2.69; 95% CI: 1.13-6.42, p =0.03). Conclusion Weight loss is associated with skeletal muscle loss during dietary treatment for MASLD. T2DM is a risk factor for severe skeletal muscle loss.

Inflammatory myofibroblastic tumors (IMTs) are rare sarcomas composed of myofibroblastic and fibroblastic cells, accompanied by inflammatory cell infiltration. Many IMTs exhibit clonal rearrangement of anaplastic lymphoma kinase (ALK). ⋯ The patient was treated with lorlatinib; however, the response duration was approximately two months. Similar case reports need to be compiled and evaluated to elucidate the efficacy of lorlatinib in post-allo-HSCT IMT with ALK rearrangement.
