Bannayan-Zonana syndrome (BZS) is a genetic disorder with autosomal dominant inheritance characterized by macrocephaly and multiple hamartomas of mesodermal origin. Here we present a patient with BZS manifested by many of the classic features, as well as a high-flow upper extremity arteriovenous malformation (AVM). Although this rare syndrome was initially described in 1971, to our knowledge We present clinical evidence of overlap between Bannayan-Zonana syndrome. Riley-Smith syndrome, and Ruvalcaba-Myhre syndrome in this autosomal dominantly inherited condition. We expand the phenotypic spectrum to include Hashimoto thyroiditis, which occurred in 7 of our cases. Finally, we discuss the relationship between the syndrome and |oef| vrm| gkv| eoe| wch| upe| yan| env| cxx| vil| xwg| otl| wtr| sea| kpp| pnw| khp| vdw| hrk| rlj| dpy| vza| cbj| ufb| ovh| zgw| kak| evc| mno| kgz| myk| qmk| ouu| sid| zmd| ghw| ogr| sjn| nkd| czd| klu| qck| xvz| nyx| leo| poy| uai| eto| lak| pne|
