Angiomyolipoma of the parotid gland: a case report.

Angiomyolipoma is a hamartomatous process that most frequently occurs as a single lesion or multiple foci in the kidneys of patients affected by tuberous sclerosis. Angiomyolipoma can also arise in extrarenal sites, among which the liver is the most frequently recorded. Only rare cases of angiomyolipoma located in the head and neck region (ear and oral and nasal cavity) have been described. The purpose of the present article is to report a case of angiomyolipoma of the parotid gland. A 68-year-old woman appeared for treatment with a slow-growing nodule located in her right parotid gland. Ultrasound examination revealed a heterogeneous nodule with well-defined margins. The nodule was surgically removed by total parotidectomy and showed the characteristic appearance of angiomyolipoma, with an admixture of fat smooth muscle cells, and tortuous, thick-walled blood vessels. Careful physical examination of the patient failed to reveal features of tuberous sclerosis. Angiomyolipoma should be considered in the differential diagnosis of mesenchymal lesions involving the salivary gland.

[Changes in the peroneal flap and its use in reconstructive surgery of the lower limb. Apropos of an experience of 10 cases]. / Variations sur le thème lambeau péronier et ses applications en chirurgie reconstructrice du membre inférieur. A propos d'une expérience de dix cas.

A peroneal fasciocutaneous flap supplied by the peroneal septocutaneous vessels and raised from the lateral side of the lower leg was reported by Yoshimura in 1983. This flap which can be used as a proximally or distally pedicled or free flap is very useful for leg skin coverage. This flap has a great potential for skin cover and composite reconstruction of the lower limb due to its multiple structural facets (cutaneo-aponevrotic or composite flap), its possible extensions to other vascular territories and the variable geometry of its mode of transfer. 8 reconstructions have been performed. Their indications are described: 4 proximally pedicled flaps (3 with the fibula), 4 reverse-flow island flaps (1 with Soleus and Peroneus longus muscles). The authors stress the importance of preoperative assessment of the feasibility of a given flap which may be limited by post-traumatic, surgical or anatomic modifications. In particular, the uppermost septocutaneous artery which corresponds inconstantly to the "circumflex peroneal artery" can only be visualized by preoperative arteriography. This artery supplies a proximal peroneal flap which can be used as an island or a free flap. We have used this new variety as a free flap in 2 cases and were satisfied with the results. These various clinical applications without any significant complication or flap failure confirm the biological performance and the safe procedure of peroneal flaps.

[Traumatic lesions of the supra-hepaticocaval veins or lessons from failure. Apropos of 5 cases]. / Les lésions traumatiques des veines sus hépatico-caves ou les leçons de l'échec. A propos de 5 observations.

Strategic therapeutic principles in 5 cases of injury to supra-hepaticocaval veins were based on vascular exclusion of liver prior to any approach to the lesion. An approach to the intrapericardial inferior vena cava by sternotomy is proposed together with the use of an endocaval shunt introduced through the atrium.

[Three cases of renal artery's aneurysm with high blood pressure (author's transl)]. / Trois cas d'anévrysme de l'artère rénale avec hypertension artérielle.

The authors report three cases of renal artery's aneurysm that caused high blood pressure. Their surgical treatment led to the cure of this high blood pressure. In one case, were applied ex situ surgery's procedures but with local replantation. Then, the authors argue the connexions between renal artery's aneurysms and high blood pressure as well as the indications for their treatments.
