case_images: She had an excisional left inguinal lymph node biopsy which revealed an enlarged lymph node with effaced architecture due to diffuse proliferation of neoplastic spindle cells (Figures 1-6). Positive tumor markers included CD4, CD30, CD45, CD43, CD68, and CD163, with a 37% MIB-1 proliferative index, consistent with HS (Figures 1-6).

case_images: Positron emission tomography (PET) scan assessment of tumor burden before CHOEP chemotherapy initiation. Increased uptake in the bilateral supraclavicular (SUV 10.9), paratracheal (SUV 12.1), hilar (SUV 12.9), periportal (SUV 10.3), left inguinal (SUV 16.9) lymph nodes, pulmonary nodule (SUV 6.1), and right hepatic lobe (SUV 4.7). CHOEP: cyclophosphamide, Adriamycin, vincristine, etoposide, and prednisone.
