Masson's tumour: Differential diagnosis of neck lump in children

Intravascular Papillary Endothelial Hyperplasia of the Vocal Cord: A Case Report and Review of the Literature

“…It is important to exclude malignant vascular neoplasm during differential diagnosis of IPEH in order to prevent misdiagnosis and inappropriate overtreatment, because IPEH is a benign condition [2,6]. The best treatment for IPEH in the head and neck region is complete surgical excision [2,5,8,11,15], but sometimes this is not feasible. Adjuvant radiotherapy or chemotherapy for remaining parts of a lesion after incomplete re-section or in cases of multiple intracranial lesions, could contribute to lesion stabilization and short-term regression [11].…”

“…Although recurrence of IPEH is rare, it has been reported after incomplete resection [2]. There have been no reports of metastatic cases, suggesting that the condition is strictly benign [2,6,8,15]. The prognosis of IPEH is usually good, but fatal clinical courses have been reported in some patients with intracranial hemorrhages [11].…”

“…In addition, IPEH has been referred to as Masson’s pseudo-angiosarcoma, endovascularite proliferante thrombopoietique, intravenous atypical vascular proliferation, intravascular angiomatosis, vascular angiomatosis, intravascular endothelial proliferation, reactive papillary endothelial hyperplasia, and intravascular papillary endothelial hyperplasia [4–6]. The condition typically exists within the lumen of dilated vascular spaces or preexisting vascular lesions [2,6–8]. It is more common in women, and can occur at any age [6,8].…”

“…The condition typically exists within the lumen of dilated vascular spaces or preexisting vascular lesions [2,6–8]. It is more common in women, and can occur at any age [6,8]. The associated clinical manifestations and radiology findings are nonspecific, and diagnosis is based on histopathology analysis [5,9].…”
