We report a case of a 77-year-old man presented with gradual lymph nodes enlargement in inguina, neck and axilla for 6 months. Biopsy revealed that part of the lymph node was replaced by several large granuloma-like nodules composed of mild atypical tumor cells, resembling epithelioid cells. Mitotic figures were hardly found. Immunohistochemistry showed that tumor cells were positive for S-100, CD68 and CD45. Ki-67 labeling index was 5%. To the best of our knowledge, this is the first case of IDCS showing granuloma-like growth pattern with mild atypical tumor cells. %A Ye, Ziyin %A Liu, Fang %A Cao, Qinghua %A Lin, Hangliang %P 274-277 %9 journal article %U https://www.termedia.pl/Interdigitating-dendritic-cell-sarcoma-of-lymph-node-mimicking-granuloma-a-case-report-and-review-of-the-literature,55,18082,1,1.html
