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.

Methotrexate may cause methotrexate-associated lymphoproliferative disorder (MTX-LPD); however, this disease is uncommon in the gastrointestinal tract. We examined six patients with MTX-LPD in the gastrointestinal tract at our hospital. All of the lesions were ulcerative. ⋯ Two patients who did not regress were negative for Epstein-Barr virus RNA, one of whom received chemotherapy, and one underwent surgery. The prognosis of this disease is considered to be good. MTX-LPD should considered when ulcerative lesions are observed during endoscopy in patients receiving MTX.

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 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.

A 50-year-old man with a triglyceride (TG) level of 11,397 mg/dL was admitted to our hospital. He consumed a high-fat and high-carbohydrate diet as well as more than 100 g of alcohol per day. ⋯ A genetic analysis revealed compound heterozygous mutations in APOA5 (c.56C>G and c.553G>T). In addition to low-fat meals and alcohol cessation, administration of pemafibrate lowered his triglyceride levels to <150 mg/dL.
