Acquired port-wine stain related to acoustic neuroma.

Abstract

Port-wine stains are frequently seen congenital vascular malformations consisting of ectatic dermal capillaries. Acquired port-wine stain that develops later in life is an uncommon vascular lesion that is morphologically identical to a congenital port-wine stain. In the majority of acquired port-wine stains, the aetiology is unknown, but trauma is an important causative factor. Other proposed aetiologies include chronic sun exposure, hormonal changes, frostbite injury, obstruction of the peritoneovenous shunt, herpes zoster infection, and cerebral arteriovenous malformation. Here we report the first case of a patient who had an acquired port-wine stain related to a solid brain tumour.

Histopathological and Immunohistochemical Profile of Benign and Malignant Oral Vascular Lesions.

“…Whereas the precise etiology of VM in this present study is unknown, we believe that the majority of cases were a consequence of reactive vascular proliferation, perhaps triggered by mechanical, hormonal, or iatrogenic causes, which remained a vascular anomaly after resolution. The preference and localization of oral VM on the lips, buccal mucosa, and tongue, where injuries were frequently observed, supports this hypothesis (14)(15)(16)(17). We suggest that VM transpiring in late adolescence or adulthood be distinguished from the common VA of infancy and childhood and that the term "acquired VM" is an appropriate designation.…”

Port-Wine Stain and Monomelic Weakness Associated With Perineurioma: A Neuromuscular Image

“…As early as 1987, an association with defective cutaneous sympathetic innervation was recognized 4 ; however, they can also be acquired and have been associated with acoustic neuroma and trauma. 5,6 When port-wine stains occur with limb asymmetry, Klippel-Trenaunay syndrome (KTS) must be considered. KTS is characterized by limb hypertrophy, port-wine stain, venous malformations, and lymphatic insufficiency.…”

Vascular Malformations

“…[ 29 ] PWS secondary to spinal root compression and herpes zoster have also been described, adding to the neural damage theory of pathogenesis. [ 30 ] Cutis marmorata telangiectasia congenita: Cutis marmorata telangiectasia congenita (CMTC), a rare congenital vascular disorder is characterized by the presence of persistent cutis marmorata (a mottled or marbled appearance of the skin) and telangiectasia (dilated superficial blood vessels), usually on the extremities. CMTC presents as a distinctive reticular or marbled pattern of the skin at birth, which becomes more prominent in response to cold temperatures.…”
