NEUTROPHILIC DERMATOSIS ASSOCIATED WITH CHRONIC NEUTROPHILIC LEUKEMIA

Chronic neutrophilic leukemia is an uncommon myeloproliferative disord er. We report a new case that fulfills the clinical and biologic crite ria for such a diagnosis. The hematologic disease was revealed by a ne utrophilic dermatosis that finally disappeared spontaneously after a d uration of 1 year. Despite the lack of parallelism in the course of de rmatologic and hematologic manifestations, we believe they were strong ly linked. Occurrence of neutrophilic dermatoses in the course of othe r myeloproliferative disorders is well known. However, in our case, cl inical and histologic features could not be used to distinguish betwee n atypical Sweet's syndrome and specific cutaneous lesions because of the mature appearance of both skin and blood neutrophils.
