ABSTRACT
Arteriovenous hemangiomas are found mainly in the limbs and scalp, and are common in women and children. However, there have been very limited reports concerning posttraumatic arteriovenous hemangioma, and none was reported in the medical literature regarding posttraumatic arteriovenous hemangioma of hypothenar eminence causing neurologic symptoms. We report a case of arteriovenous hemangioma of hypothenar eminence after recurrent trauma that was successfully treated by an excision of the mass and vein graft.

Vulvar ateriovenous hemangioma is a rare pathologic lesion, encountered in Bartholin's glands of vulva. Little has previously described in the litherature. A painless vulvar mass occurred accidently in a healthy women after cesarean delivery. There was no obvious lesion on the skin. Excisional biopsy revealed a vascular lesion in the subcutaneous layer, consistent with arterio-venous hemangioma. The mass was sucessfully treated by excision, and the patients was asymptomatic for five months later. so, we report this case with a brief review of literatures.

We experienced three cases of arteriovenous hemangioma in middle-aged patients. Each of them an asymptomatic small red to purple papule on the face and arm, which showed typical microscopic features of proliferating variously sized vessels in the dermis. An interesting finding was the increased number of mast cells identified in the stroma and perivascular channels, which may be associated with angiogenesis in inflammatory and neoplastic processes. Although arteriovenous hemangioma has been reported infrequently, its true incidence is considered to be higher than expected. Thus biopsy should be performed for exact diagnosis of small vascular lesions.

Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.
