case_images: Histopathology: superficial and deep perivascular neutrophilic infiltrate
  in the dermis and dense mixed infiltrate of neutrophils, lymphocytes,
  and medium-size atypical round cells in the lobules and septa of adipose
  tissue (Hematoxylin & eosin, X100)

case_images: C were negative. Bone marrow biopsy showed cellularity of 95% with predominance of granulocytes and their precursors, as well as megakaryocytic hyperplasia with hypo and hyperlobulated forms, compatible with chronic myeloproliferative disease. Cutaneous biopsy revealed normal-appearing epidermis, mild superficial and deep perivascular neutrophilic infiltrate in the dermis, and dense mixed infiltrate of neutrophils, lymphocytes, and medium-sized atypical round cells in the lobules and septa of adipose tissue, with surrounding megakaryocytes (Figure 3).
