In 1987 a 73 year old man was diagnosed with a malignant sarcoma of the anus. It was originally regarded as a leiomyosarcoma. Fourteen years later the original diagnoses of the specimen was reviewed and the diagnosis was changed to GIST (gastrointestinal stromal tumour). This diagnosis was confirmed with appropriate immunohistochemical staining on the tumour tissue. This is the first case of GIST in the anus diagnosed in Iceland.
