PTCH1 and embryonal rhabdomyosarcoma: Nineteen patients (51%) had embryonal RMS (ERMS) (including three highly differentiated ERMS with PTCH deletion), eight (22%) had spindle cell RMS (SRMS) (three VGLL2‐, one NTRK‐, and two (B)RAF‐fusions), six (16%) had alveolar RMS (ARMS) (all FOXO1‐ or PAX3‐fusion), two had unclassified RMS, and two poorly differentiated RMS were retrospectively diagnosed as rhabdoid tumors (RT) with loss of INI1 expression.
