A 21 year old woman presented with multiple lobulated lesions on the labia majora. The surface of most of the lesions was ulcerated revealing a glistening surface. All lesions were excised. The histopathology revealed features suggestive of lobular capillary haemangioma (pyogenic granuloma). Pyogenic granuloma is considered as a reactive hyperproliferative vascular response to trauma or other s...

The management of vascular anomalies is an extremely challenging area and is as as divergent as the nature of the lesions. Traditionally, embolization with the resection of the lesion has been used. The purpose of this report is to present a case treated successfully using sclerosing solution injections alone. METHODS: Management of the arterio venous malformation using Intralesional injections...

Starting with a case report, we made a detailed review of the literature, with the purpose of identifying and analyzing the type of iatrogenic vascular lesion following knee arthroscopy and the method of vascular repair. A PubMed literature search was undertaken to locate all reported cases of major vascular iatrogenic injuries during arthroscopic knee procedures. We identified 39 papers which ...

Hemangiomas are tumors of blood vessels identified by rapid endothelial cell proliferation in early infancy followed by involution over time. All other abnormalities are malformations resulting from anomalous development of vascular plexuses. This lesion in the oral cavity is not common. Despite its benign origin and behaviour, it is always of clinical importance to the dental profession and re...

A 24-year-old woman presented with asymptomatic hyperpigmented bilateral patches on her temples, eyelids and forehead since birth. Furthermore, the patient had a congenital grey patch, compatible with Mongolian spot, on her buttock. She had no vascular or other cutaneous lesion. Histopathologic examination revealed bipolar dendritic melanocytes dispersed in a ribbon-like pattern between the col...

In our case, the history, clinical findings, negative biochemistry and CT and MIBG scans indicated that the lesion might be a non-catecholamine-secreting paraganglioma. The final diagnosis of a vascular malformation was unexpected but revealed an interesting differential diagnosis of a rare pathology. Retroperitoneal vascular malformations of the choledochus, kidney and pancreas have been descr...

The development of an iatrogenic vascular lesion, such a renal pseudoaneurysm or arteriovenous fistula, is a rare complication of partial nephrectomy. These lesions should be considered in patients presenting with an enhancing mass in the resection bed shortly following partial nephrectomy. Early timing following surgery, large relative size, and the presence of recurrent hematuria suggest the ...

17-β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) is an important enzyme involved in the final steps of androgen synthesis and is required for the development of normal male external genitalia. 46,XY individuals with deficiency of this enzyme present a wide clinical spectrum from a female appearance of the external genitalia through ambiguous genitalia to a predominantly male genitalia with m...

OBJECTIVE The objectives of this study were to determine the role of response gene to complement 32 (RGC-32) in vascular lesion formation after experimental angioplasty and to explore the underlying mechanisms. METHODS AND RESULTS Using a rat carotid artery balloon-injury model, we documented for the first time that neointima formation was closely associated with a significantly increased exp...
