An unusual mole: an adult case of Dabska tumour

Abstract

In 1969 Dabska and her colleagues described for the first time this rare malignant tumour, also later known as a malignant endovascular papillary angioendothelioma of childhood. Overall, depending amongst other factors on its location, it is thought to have a generally favourable prognosis and a wide local excision seems to be the treatment of choice. We here present a very rare and unusual case of a 63 year old woman with a 20 year history of slow-growing right buccal dermatological lesion which resembled a common mole. The histopathological diagnosis of Dabska Tumour was made following the hematoxylin and eosin (H&E) biopsy. The analysis revealed multiple delicate interconnecting vascular channels with papillary plugs, some of which containing hyalinized core, projecting into the lumen lined by atypical plumped endothelial cells.
