Extragonadal yolk sac tumour (YST) is rare, and may present a diagnostic challenge. YST differentiation was recently reported in some somatically derived tumours in the sinonasal location and in the female genital tract, together with a SMARCB1/INI1 loss. We report two paratesticular/inguinal tumours with striking morphological and immunohistochemical similarities with YST, further expanding the spectrum of extragonadal tumours with YST‐like morphology and SMARCB1/INI1 loss.
