Spindle cell haemangioendothelioma in an arteriovenous fistula of the ring finger after blunt trauma

Multiple mucinous and lipomatous variant of eccrine angiomatous hamartoma associated with spindle cell hemangioma: a novel collision tumor?

“…Although SCH initially presents as a distinctive low‐grade variant of angiosarcoma and can be classified into vascular tumors of intermediate or low‐grade malignant potential, it has been suggested that spindle cell hemangioendothelioma may be a non‐neoplastic, reactive process arising in association with a local congenital or acquired vascular malformation 4,7,16–18 . SCH can be associated with epithelioid hemangioendothelioma, congenital lymphedema, Maffucci's syndrome, Klippel–Trénaunay syndrome, early onset varicosities, Kasabach–Merritt syndrome, and arteriovenous fistula 4–7,19–21 . As we had evaluated bony abnormalities of our patient using MRI, possibility of Maffucci's syndrome can be ruled out.…”

“…4,7,[16][17][18] SCH can be associated with epithelioid hemangioendothelioma, congenital lymphedema, Maffucci's syndrome, Klippel-Trénaunay syndrome, early onset varicosities, Kasabach-Merritt syndrome, and arteriovenous fistula.

Spindle Cell Hemangioendothelioma of the Temporal Muscle Resected with Zygomatic Osteotomy: A Case Report of an Unusual Intramuscular Lesion Mimicking Sarcoma

“…However, recent evidence indicates that the majority of lesions are partially or exclusively intravascular [6]. Therefore, “recurrence” is defined as contiguous or multifocal spreading of the lesion along an affected vessel [6, 7, 10]. Overall, prognosis is excellent and no metastases from SCH have been reported to date [6].…”

Les anomalies vasculaires de la main de l’enfant

“…Congénital ou acquis dans les premières années, il s'agit de plaques rouges infiltrées, parsemées de papules rouges, douloureuses au toucher [9]. D'autres tumeurs vasculaires rares ont été décrites au niveau de la main de l'enfant : l'hémangioendothéliome épithélioïde [10], l'hémangioendothéliome à cellules fusiformes [11] et quelques cas de tumeurs malignes (angiosarcomes, lymphangiosarcome, angioleiomyome) [12].…”
