Three atypical manifestations of granulomatosis with polyangiitis: lateral medullary syndrome, anterior cheek mass and melting scleritis of eye

: Granulomatosis with polyangiitis (GPA, formerly Wegener granulomatosis) is a vasculitis with various organ involvement. There have been a few cases of CNS stroke and rare cases of lateral medullary infarction (LMI) as a manifestation of GPA. Also there have been reports of sinuses, nose and laryngeal masses mistakenly referred as carcinomas and subsequently GPA was diagnosed in their pathological reports. Another severe fulminant manifestation can be necrotizing scleritis leading to perforation of sclera. Therefore, here we present some rare and fulminant manifestations of GPA in 3 separate cases for further emphasis of the unusual manifestations of GPA that should always be kept in mind.
