[Lymphangioma with epithelial hyperplasia included in a Bardet-Biedl syndrome]. / Lymphangiome avec hyperplasie épithéliale associé à un syndrome de Bardet-Biedl.

INTRODUCTION: The Bardet-Biedl syndrome is a rare autosomal recessive disorder, which associates obesity, pigmentary retinopathy, hexadactyly, hypogenitalism, renal dysfunction and mental retardation. Other abnormalities can be observed in the Bardet-Biedl syndrome, but few cutaneous abnormalities have been described. CASE REPORT: A 41 year-old woman, suffering from a Bardet-Biedl syndrome diagnosed when she was 7 Years old, presented with an atypical pseudo verruca-like, dark red lesion of the interbuttock area that had developed over fifteen Years and had become a handicap. The histological examination revealed a double component: epithelial, papillomatous and acanthosic on the one hand and vascular and lymphatic on the other, suggesting a lymphangioma with epidermal hyperplasia. Magnetic resonance imaging of the sacral area revealed a median subcutaneous lesion, extending deeply to the third coccygial vertebra. DISCUSSION: Such a lymphangioma is unusual. Because it occurred during a rare polymalformative syndrome, we suggest that it may represent a new clinical sign that can be observed during the Bardet-Biedl syndrome.

[Colonic angiodysplasia. Rare cause of low digestive hemorrhage in young patients]. / Angiodysplasie colique. Cause rare d'hémorragie digestive basse du sujet jeune.

We report the following observation of a diffuse kind of colic angiodysplasia in a young subject. Usually to be find in old subjects and regarded as been degenerative origine, angiodysplasiae have been reported in young subjects and we are led to ponder over their nature. The contribution of diagnostic and therapeutic means and their respected place have been specified. In particular the significance of vascular radiology and the angiographic signs of this arterioveinous malformation have been developed.

[Retroperitoneal lymphocele: a rarely reported complication of abdominal aortic surgery. Apropos of a case]. / Lymphocèle rétropéritonéale: complication rarement décrite de la chirurgie aortique abdominale. A propos d'un cas.

The authors present a case of a retroperitoneal lymphocele following prosthetic reconstruction of the abdominal aorta followed by a discussion about the principal differential diagnosis of a retroperitoneal collection following surgery on abdominal aorta. To date, only ten cases have been reported in this post-operative; it is probably a more frequent complication; the radiologist must play a major role both in the detection and the treatment of such collections.
