A 63-year-old woman with adult T-cell leukemia (ATL) lymphomatous type developed a mild dry cough. Computed tomography revealed lung lesions with a tree-in-bud appearance during intensive chemotherapy. Antibodies against Mycobacterium avium complex were positive. ⋯ Finally, M. abscessus subsp. massiliense was also identified. Sequential use of antimicrobials, including macrolides, was introduced during intensive chemotherapy, and the patient successfully underwent allogeneic hematopoietic stem cell transplantation (AHSCT). This is the first case report of a patient with ATL complicated by M. massiliense lung infection, who was successfully treated with haploidentical AHSCT using various combinations of antimicrobials.

Spontaneous abdominal wall hematoma is a relatively uncommon condition triggered by various factors, including anticoagulation therapy and trauma. However, reports of unprovoked cases without anticoagulants that recur shortly after treatment are limited. ⋯ This case highlights the possibility that patients with underlying predisposing factors may experience early hematoma recurrence at the same site, even in the absence of apparent triggers. Clinicians should monitor these patients to promptly identify and address potential recurrences.

Alice in Wonderland syndrome (AIWS) is extremely rare, occurring more often in young individuals than in older adults. Symptoms of this syndrome typically include an altered body image, size perception, and time perception. ⋯ Two patients with isolated cortical venous thrombosis in the right occipital area experienced transient visual symptoms of AIWS. Furthermore, a literature search indicated that AIWS with visual distortions is associated with right occipital lobe lesions, supporting the findings of our study.

Gastrointestinal pseudo-obstruction (GIPO) is a phenotype of the paraneoplastic neurological syndrome (PNS). We herein report a case of small-cell lung carcinoma (SCLC) with GIPO elicited by an immune checkpoint inhibitor (ICI). A 75-year-old man with SCLC developed intractable intestinal obstruction after receiving one course of anticancer drugs (durvalumab, etoposide, and carboplatin). ⋯ Corticosteroid treatment did not improve the GIPO, and the patient died. There are few reports of GIPO after ICI treatment in patients with lung cancer, so a further investigation will be required to elucidate the mechanism by which ICIs elicit PNS. Checking for neuronal antibodies may help identify patients with SCLC who are at risk of developing PNS due to ICI treatment.

A 52-year-old man who had been using a proton pump inhibitor (PPI) and a potassium-competitive acid blocker (P-CAB) for 14 years underwent esophagogastroduodenoscopy and was found to have three neuroendocrine tumors (NETs) in the gastric body. Following detailed examinations, parietal cell dysfunction was excluded, and the NETs did not meet the criteria for the Rindi classification types I-III. The lesions were ultimately considered to be associated with the long-term use of the PPI and P-CAB. We performed endoscopic submucosal dissection of the lesions, with no recurrence or new lesions noted after discontinuation of the PPI and P-CAB.
