Long-term therapeutic outcomes of facial arteriovenous malformations: A retrospective bi-centric study of 30 cases.

INTRODUCTION: Among vascular malformations, arteriovenous malformations (AVM) are potentially the most invasive and destructive especially when located on the face. Their management is still subject to controversy and yet no consensus exists. Our aim was to report long-term therapeutic outcomes for patients with facial AVM managed either by embolization alone or by resection with/without preoperative embolization. MATERIAL AND METHODS: A bi-centric retrospective study was carried out covering the period from 2001 to 2018 including 30 patients with a facial AVM. Outcomes were categorized as follows: with 1=controlled disease, 2=improved disease (residual, no expansion), 3=persistent or stable disease (neither improved nor worsened), and 4=recurrent or worsened disease. RESULTS: The initial treatment modality was embolization (n=5, 16.7%), surgical resection (n=16, 53.3%), and surgical resection after embolization (n=9, 30%). The follow-up period ranged from 12 to 216 months with a median of 54.9 months. Taking all treatment modalities together, disease control was achieved in 60% of the cases. Disease control was achieved in 77.8% of the cases after embolization followed by surgery, in 68.7% after surgery alone and in none of the cases after embolization alone. CONCLUSIONS: According to our results, optimal treatment is based on a combination of embolization followed by a well-conducted surgical treatment.

[Adipocytic tumors of the salivary glands: A retrospective study]. / Tumeurs adipeuses des glandes salivaires: étude rétrospective.

INTRODUCTION: Adipocytic tumors are the most common soft tissue mesenchymal tumors. Their occurrence in salivary glands is rare. We studied the epidemiology, the diagnostic and the therapeutic features of the salivary adipocytic tumors followed in our department. PATIENTS AND METHODS: A retrospective study was conducted in our department between January 1997 and December 2011. Nine cases of adipocytic tumors of the salivary glands were found. Data were collected from medical records and processed by Excel. RESULTS: Mean age was 44 with a clear predominance of males (sex ratio: 3.5). In 8 cases the tumors were benign (7 lipomas and 1 lipofibroma). The only malignant tumor was a metastatic myxoid liposarcoma. Parotid was the main location (8 cases/9). Ultrasonography and MRI were prescribed. The treatment was tumor and parotid gland removal with conservation of the facial nerve excepted in the malignant case. One transient facial palsy, two earlobe dysesthesia and one retromandibular depression were observed. No recurrence was noted. DISCUSSION: Our study confirmed the epidemiological profile of these adipocytic salivary gland tumors, which are rarely observed, but mainly in the parotid gland. They are often benign and lipoma is the main histological type.

[Intraorbital dermoid cyst. Case report and review of the literature]. / Kyste dermoïde intraorbitaire. À propos d'une observation et revue de la littérature.

Periorbital dermoid cysts are benign tumors most often seen in young children. Intraorbital location, though rare, should not be overlooked. Good quality imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures, as well as in planning the surgical approach. The authors report a case of a 46-year-old male with an intraorbital dermoid cyst presenting with progressive left proptosis. Appearance on imaging (CT and MRI) was consistent with intraorbital dermoid cyst. The tumor was extirpated. Histopathologic examination confirmed the diagnosis of dermoid cyst. We also present a review of the literature.
