[Odontogenic myxoma: About four cases and review of the literature].

Objective: Odontogenic myxoma is an uncommon tumor that represent less than 0,5% of all bone tumors and only 3 to 6% of odontogenic tumors. The aim of this article was to catalogue the clinical cases diagnosed microscopically as odontogenic myxoma and to describe their clinical and radiographic characteristics, comparing these to the data found in the current literature.

Design: Histological and immunocytochemical examinations were performed on odontogenic myxomas from four Tunisian patients in a period of 23 years.

[Facial infantile aggressive fibromatosis: a frequent localization of an exceptional tumor!].

Introduction: Although fibromatosis is considered as benign tumor, it can have significant morbidity, particularly when it occurs in the head and neck. Their propensity for infiltrative local growth with encroachment on vital structures and their tendency to recur make fibromatoses of the head and neck extremely challenging lesions.

Case Report: We report the case of a 10-year-old boy with desmoid fibromatosis of the upper lip.

[Mandibular fracture: a 10-year review of 685 cases treated in Charles-Nicolle Hospital (Tunis-Tunisia)].

Introduction: The epidemiology and treatment of mandibular fracture vary from one country to another. The aim of this study was to present the current demographic pattern and treatment regimens of mandibular fractures in Tunisia.

Methods: The medical records and radiographs of 685 patients treated for mandibular fracture at the Maxillofacial and Plastic Surgery Department in the Tunis Charles-Nicolle Hospital between 1995 and 2004 were retrospectively studied.

[Fractured zygoma: a review of 356 cases].

Introduction: Fractures of the zygomatic complex with its accompanying functional and esthetic deficits are a fairly common phenomenon in the practice of maxillofacial and plastic surgery. The purpose of this paper is to provide a review, based on collected data, on the topic of "fractured zygoma". The review is presented under the headings of epidemiology, fracture patterns, treatment modalities and complications.

[Columella defects: yet a challenge!].

The repair of nasal defects is thought to be the most ancient of facial reconstructive procedures, dating back to at least 3000 BC in India. In spite of the development of nasal reconstruction concepts, leading to remarkable esthetic and functional improvements, columella reconstruction is yet a contemporary challenge. Columella defects may result from trauma, infections, carcinoma resection, syphilis, bilateral cleft lip, etc.

[Epidemiology of maxillofacial traumatology in Tunis].

Introduction: The aim of this study was to assess the epidemiology of maxillofacial trauma in Tunisia over a 10-year period.

Methods: This retrospective study was carried out between 1995 and 2004 on patients admitted for maxillofacial trauma in the department of maxillofacial and plastic surgery of the Charles-Nicolle Hospital in Tunis. The selected relevant parameters were: age, gender, etiology, time of trauma, type of fracture and associated lesions.

B-cell lymphoma of the mandible: a case report.

Introduction: The mandible is an infrequent localisation of primary osseous non-Hodgkin's lymphomas. Few cases of mandibular non-Hodgkin's lymphomas (NHL) have been reported.

Case Report: A rare condition of primary malignant non-Hodgkin's lymphoma of the mandible in 53-year-old man, was reported at the Department of Maxillofacial and Plastic Surgery in Charles Nicolle Hospital (Tunis, Tunisia).

[Place of the precocious surgical treatment in facial hemangioma].

Infantile cutaneous hemangioma is a benign vascular tumour present at 10% of the infants. It forms part of the group of the vascular tumours in the classification of international society for vascular anomalies (ISSVA). Usual surgical attitude is abstention and surgery is proposed only in order to treat sequelae.

[Amniotic band syndrome and facial malformations].

Amniotic band syndrome (ABS) is a collection of fetal congenital malformations affecting mainly the limbs, but also the craniofacial area. The pathogenic mechanism is still unclear. The facial malformations in ABS are multiple, polymorphous, and asymmetric.

[Mandibular aggressive fibromatosis].

Introduction: Aggressive fibromatosis is a rare histologically benign fibrous tumor with a potential for locoregional aggression. Treatment is not well defined and several therapeutic approaches have been proposed. Surgical treatment is the reference, chemotherapy, radiotherapy and homonotherapy being proposed as complementary treatment or for inoperable tumors.

Lipomatous hemangiopericytoma (adipocytic variant of solitary fibrous tumor) of the orbit. A case report with review of the literature.

Hemangiopericytoma (HPC) of the orbit is a rare tumor presenting with slowly progressive proptosis, ocular motility impairment and visual loss. In 1995, a newly variant of HPC termed lipomatous hemangiopericytoma (LHPC), was described. Only two cases arising in the orbit have been previously reported.

[Adenomatoid odontogenic tumor: two cases].

Introduction: Adenomatoid odontogenic tumor, initially referred to as adenoameloblastoma, is a rare and benign odontogenic tumor. No recurrence has been reported after enucleation-resection.

Case Reports: We report two cases of adenomatoid odontogenic tumor, which illustrate the radiological and anatomic features of this tumor.

[Primary malignant melanoma of the nasal cavity presenting as a large tumor of the cheek].

Introduction: Malignant melanoma of the nasal cavity is a rare tumor usually causing unilateral nasal obstruction and nasal bleeding. Diagnosis is achieved with immunohistochemistry analysis. Surgery is proposed for curative treatment.

[Primary mucinous carcinoma of the skin. A case report].

Primary mucinous carcinoma of the skin is a rare sweat-gland neoplasm with a high recurrence rate. We report a new case of a primary recurrent mucinous carcinoma of the face in a 59-year-old man. Histopathologic examination of the neoplasm showed epithelial islands floating in mucoid material compartmentalized by fibrous septa.

[Malignant transformation of a dermoïd cyst of the scalp. A case report].

Dermoïd cysts are benign tumours, resulting of an embryologic defect. They usually have good prognosis, only a single case of malignant transformation of a sublingual dermoid cyst has been brought back in literature. We report a case of carcinomatous transformation of a dermoïd cyst of the scalp, in a 54 years old man.
