Delayed and Synchronous Recurrence of Breast Cancer Metastases in Multiple Organs: A Case Report.
The most common sites of breast cancer metastasis include the lymph nodes, bones, lungs, liver, and brain. Gastrointestinal tract metastasis is rarely seen, and hypopharyngeal metastasis is extremely rare. We herein report a case of late distant recurrence of breast cancer and synchronous metastasis to the hypopharynx, stomach, ileum, bones, and lymph nodes almost 24 years after surgery. To our knowledge, this is the first case of synchronous metastasis to the hypopharynx, gastrointestinal tract, and other organs, especially after a long interval following primary mastectomy.

Medium-vessel Vasculitis Presenting with Myalgia Following COVID-19 Moderna Vaccination: A Case Report.
Coronavirus disease 2019 (COVID-19) vaccines have been delivered worldwide to prevent the spread of the disease, and almost all Japanese have received the mRNA vaccines "BNT162b2" (Pfizer-BioNTech) or "mRNA-1273" (Moderna). These vaccines have shown efficacy and safety with only minor adverse drug reactions. ⋯ However, only a few investigators have reported medium-vessel vasculitis following vaccination. We herein report a case of medium-vessel vasculitis presenting with myalgia as the initial clinical manifestation following COVID-19 Moderna vaccination.
