An unusual mole: an adult case of Dabska tumour.

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.

Coblation debulking of a paediatric laryngeal plexiform neurofibroma: a pragmatic response to a rare tumour.

Laryngeal neurofibroma is a rare but important differential diagnosis in a patient presenting with stridor. In paediatric patients, these lesions present a management conundrum: complete surgical resection is the established treatment of choice, but an aggressive approach can be detrimental to developing anatomy. We report the case of a plexiform neurofibroma affecting the right hemilarynx of a 3-year-old boy. Endoscopy revealed a large tumour, involving the right aryepiglottic fold and extending into the piriform sinus, ventricle and the false cord. Given the patient's young age and the challenging tumour location, the lesion was debulked, rather than resected, using coblation (low-temperature plasma radiofrequency ablation). At 30 months follow-up, the neurofibroma has mildly increased in size-in line with expectations that these lesions exhibit slow growth throughout childhood-but there are no significant respiratory symptoms and there is no functional impairment.
