Intra-abdominal desmoplastic small round cell tumor has been described in the
literature since 1989. It is characterized by the occurrence in ages less than 40 with
male predominance, an intra-abdominal location, and small round to oval shaped tumor
cells with divergent differentiation in the background of the desmoplastic stroma.
We recently experienced this tumor in an inguinal lymph node of a 36-year-old man. It
is suspected that it metastasized from a lower intra-abdominal tumor.
Immunohistochenlical stains for keratin, epithelial membrane antigen, vimentin, S-100
protein and neuron specific enolase were positive. This is the first documented case in
Korea. Herein, we report on this tumor with a review of literature.
