Despite multiple consultations, no diagnosis was made, and she developed painful swelling with a limping gait. A biopsy was done on July 14, 2023, confirmed metastatic EMC. FDG PET/CT revealed widespread metastases, including in the lungs, pleura, mediastinal, hilar, inguinal, right external iliac nodes, left labia majora, left iliac bone, left tibia, and left foot.
