An 86-year-old male noticed a purple macule on the left cheek after a shaver injury in Sep. 1999. Histological examination of the macule revealed a diffuse proliferation of anaplastic cells with large nuclei in the dermis and subcutaneous tissue. The tumor cells were positive for CD56 and TdT. EBER and TCR gene rearrangement were negative. Based on these findings, we diagnosed this case as blastic NK cell lymphoma. Radiation therapy was performed and the number of the tumor cells reduced remarkably histologically. However macule recurred on forehead and chest four months later.
