Neutrophilic dermatosis of the dorsal hands is a variant of Sweet's syndrome. We herein describe an 83-year old woman with a neutrophilic dermatosis of the dorsal hands associated with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon. To our knowledge, and after a search in PubMed, the association of Sweet's syndrome with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon has not previously been reported.
