A 46-year-old woman with lung cancer who received chemotherapy was admitted to our hospital for lower-lobe bilateral ground-glass opacity (GGO). GGO developed after the lung cancer diagnosis, deteriorated after the initiation of osimertinib, and incompletely decreased after interrupting osimertinib; therefore, flexible bronchoscopy was performed. Transbronchial lung biopsy histology and anti-granulocyte/macrophage colony-stimulating factor autoantibody positivity revealed autoimmune pulmonary alveolar proteinosis (aPAP) that did not require treatment. This rare case of aPAP comorbid with lung cancer suggested that using PAP findings to differentiate from drug-induced lung injury or lymphangitis is difficult and that osimertinib was suspected to exacerbate aPAP.

Pemigatinib is a fibroblast growth factor receptor inhibitor (FGFRi) approved for the treatment of patients with previously treated biliary tract cancer with FGFR2 fusion. Although infrequent, ocular toxicity manifested as serous retinal detachment (SRD) has been observed and is regarded as a serious side effect. We herein report the case of a 54-year-old woman with unresectable cholangiocarcinoma-initiated pemigatinib after failure of gemcitabine plus S-1 (GS). Although the patient experienced repeated SRD after pemigatinib, dose interruption and dose reduction of pemigatinib from 13.5 mg to 9 mg, and from 9 mg to 4.5 mg led to complete recovery of SRD, and continued tumor shrinkage.

Mahjong is one of the most popular Chinese tile games played in Japan. Mahjong-related seizures (MRS) are rare praxis-induced seizures. We identified three patients with MRS from February 2000 to February 2021. ⋯ They did not have features linked to idiopathic generalized epilepsy. All patients were seizure-free after behavioral adjustments, although one patient required anti-seizure medication and avoided long duration games. These changes may help other patients with MRS continue playing Mahjong.

Review Case Reports
A Case of a Pregnant Woman with IgA Nephropathy Showing Histological Preeclampsia Findings without Hypertension Treated with Steroids: A Case Report and Literature Review.
A 35-year-old woman pregnant with twins developed nephrotic syndrome (NS) at 33 weeks' gestation, but her blood pressure remained within the normal range throughout gestation and puerperium. At 34 weeks' gestation, she delivered healthy twins via Caesarean section. ⋯ She was treated with steroids, and the NS gradually resolved. This is a rare case of massive gestational proteinuria with IgAN and preeclampsia pathologically that did not meet the clinical criteria for preeclampsia.
