definitive diagnosis should be based on the presence or absence of extracutaneous disease at diagnosis. Testicular B-cell lymphoma can also affect the skin and its pathologic and immunophenotypic characteristics are indistinguishable from those of PCDLBCL, leg type; routine testicular examination is therefore recommended in appropriate cases. We have reported a case of systemic DLBCL diagnosed following the detection of a cutaneous lesion without other signs or symptoms. One particularly interesting aspect of this case was the presence of a solitary lesion that clinically resembled a primary cutaneous lymphoma.
