Fig. 1From: Alveolar rhabdomyosarcoma confined to the bone marrow with no identifiable primary tumour using FDG-PET/CT a Histological and genetic characteristics of bone marrow infiltrating cells. Top left Infiltration of the bone marrow by medium to large atypical cells (×40), right top corner (×100); top right Gelelectrophoresis of PAX/FKHR RT-PCR including positive and negative controls for PAX7- und PAX3-FKHR fusions in two dilutions (neat and 1:50), below results of Sanger sequencing; bottom panel the atypical cells express desmin, CD56 and MyF4. b Left panel Whole body positron emission tomography (PET-CT); top right panel PET-CT indicating one single increased uptake in the right thyroid gland revealing follicular neoplasia; bottom right panel haemangioma in the 9th thoracic vertebraeBack to article page
