EJD, vol. 31, n◦ 2, March-April 2021 in this process, although gene analysis was not performed in the present case. The present patient and the previously reported patient [3] were followed for more than four and six years, respectively, after the development of subcutaneous metastasis. Cutaneous/subcutaneous metastases of GIST does not always predict poor prognosis. In conclusion, subcutaneous nodules in patients with a history of GIST should be biopsied immediately. If a spindle cell tumour such as a leiomyoma, leiomyosarcoma or dermatofibrosarcoma protuberans is suspected, subcutaneous metastasis of GIST should be considered as a differential diagnosis, even many years after the primary GIST resection.
