Progressive changes of Warthin’s tumour after thin needle biopsy are well known. The predominating histopathological feature is in addition to pavement metaplasia coagulation necrosis which is rarely associated withcomplete eradication of the original structure of thetumour. An absolute rarity is the finding of a granulomatous inflammation which completely absorbs the necrotic tumour. So far only one such case was described. We recorded a similar case of a bilateral Warthin tumour with complete regression which occurred after thin needle aspiration biopsy. It involved a 61-year-old man with bilateral swelling of the parotid gland which developed asymptomatically for six months. Ultrasonography and thin needle biopsy proved a Warthin tumour. The patient was indicated for surgery to be implemented in a month time. Eight days before the planned operation he developed bilaterally a necrotizing inflammation in the parotid area. Under general anaesthesia an incision was made with evacuation of mucopurulent contents. The microscopic finding confirmed necrosis without signs typical forWarthin’s tumour. Bacteriological examination and histopathological evidence for the presence of molds and bacteria in the removed debris was negative which rules out the possibility that a bacterially infected node was involved or another affection of the glandular parenchyma.
