Those who have<unk>  often present with skin lesions that do not heal with normal medication. A blood test generally reveals any change in the levels of lymphocytes in the blood, which is often associated with a cutaneous T-cell lymphoma. Finally, a biopsy of a skin lesion can be performed to rule out any other causes. The immunohistochemical features are very similar to those presented in mycosis fungoides except for the following differences: # More monotonous cellular infiltrates (large, clustered atypical pagetoid cells) in<unk>  syndrome # Sometimes absent epidermotropism # Increased lymph node involvement with infiltrates of<unk>  syndrome.
