Bilateral tumoral infiltration of the Achilles tendons revealing chronic myelomonocytic leukemia

Extrahematologic manifestations, such as symptoms of rheumatic disease, have been recorded in association with myelodysplastic syndromes, including chronic myelomonocytic leukemia (CMML). We report the case of a 51-year-old woman with tumoral infiltration of the Achilles tendons bilaterally, indicating CMML. This diagnosis was confirmed at postmortem examination.
