This paper reports a case of a woman with acquired hypertrichosis lanuginosa in relation to a breast carcinoma. Stomatological symptoms such as glossitis and taste changes are frequently associated. A review of the literature is made.

This work reviews all the data actually known about the epidemiology and the etiopathogenesis of the oral cancer. Based on an exhaustive literature review, this paper analyses the epidemiological and etiopathogenic factors of the oral cancer.
The authors report their experience with reconstruction of loss of mandibular substance due to wide or complicated resections for cancer. A series of 8 reconstructions using a latissimus dorsi osteo-myocutaneous pediculated flap and the 10th rib helped to define the advantages and disadvantages of this form of complex flap. Since a latissimus dorsi pediculated flap has classically been used in maxillo-facial reconstruction, an osteo-myocutaneous flap, including a portion of the 10th rib, is naturally appropriate for the reconstruction of a major loss of substance involving the mandible and related structures. The separation technique and trans-cervical transposition are described. The advantages of this form of flap are the ease with which it may be detached and the reliability of the vascular pedicle. The principal disadvantages are the relatively large volume, the difficulty in dissociating the cutaneous layer from the bony layer and the difficulties involved in the fixation of the bone graft to a prosthetic plate. Problems with rehabilitation are also discussed.
This study reviews the various lymphoid tumors affecting the bony maxilla. If cervico-facial localizations of lymphoid tumors are frequent, they are relatively rare within the bony maxilla. Hodgkin's-like lymphomas are exceptionally rare: non-Hodgkin's lymphomas, among which are Burkitt's lymphomas and Ewing's sarcomas, are slightly more frequent. Granulocytic sarcomas, myelomas and plasmacytomas are rarely found in the maxilla. The different epidemiological, etiological, clinical, radiological, histological and therapeutic characteristics of each tumor is described along with a review of the recent literature.
A case of extraarticular temporomandibular ankylosis due to progressive ossifying myositis is reported. The local pathology appeared 13 years after the initial generalized symptomatic onset. CT scan helps to the diagnosis. Despite surgical therapy, the pathology reappears so we conclude to the unique efficiency of medical therapy: corticosteroids by pulse therapy. A review of the literature on the subject was made. A discussion ends the publication.
The reconstruction of palatal defects of tumoral, malformative or traumatic origin remains a surgical challenge. The various surgical techniques available are reviewed in this paper, together with prosthodontic palatal obturators. One case of palatal reconstruction with a buccinator mucomuscular island flap is reported. The advantages of the buccinator flap seem noteworthy when compared with the disadvantages of the currently used flaps.
In this clinical single-blind trial, the potential analgesic effect of pirprofen (Rengasil) was compared to the analgesic effect of piritramid (Dipidolor). The two compounds were tested intramuscularly in patients submitted to maxillofacial surgery. Pirprofen and piritramide seem to have an equivalent analgesic effect but pirprofen (Rengasil) seems to act a little faster and to be better tolerated than piritramid. Therefore, pirprofen may be utilized with success to treat postoperative pain in patients who undergo maxillofacial surgery: its advantage is avoiding secondary effects of the morphinomimetic compounds.

This review analyses the epidemiology, the clinical aspects, the diagnosis and the therapy of the epithelial malignant tumors of the parotid gland. The diagnostic approach by means of modern radiological technics and the therapeutical problems were particularly emphasized.
The vascular tumors of the jaw bones are rare. Misdiagnosed, these tumors represent a vital danger for the patient submitted to a surgical work in this area. The treatment of these vascular tumors is oft difficult and leads yet too much to maxillofacial mutilations. The superselective embolisation has permit a more conservative therapeutic approach to these lesions.
The rare cartilaginous tumors of the jaw bones are either benign or malignant. Their histogenesis is oft not clear, their histology and differential diagnosis always difficult. The clinical and radiological characteristics are very poor and of no aid for the diagnosis; the treatment must always be surgical. On the light of the recent literature, this work analyses these different characteristics of the cartilaginous tumors of the jaw bones. The benign tumors are the osteochondroma, the chondroblastoma, the chondromatosis synoviae and the myxoid fibroma. The malignant tumors are the various chondrosarcomas: among them, the mesenchymal chondrosarcoma is separately described.
This is a clinical report of a nevus cell nevus arising on the palatal mucosa. The incidence, the etiology, the differential diagnosis and the treatment of this mucosal pigmented lesion are reviewed.
Non-odontogenic cystic lesions and so-called "pseudocystic" lesions of the jaws are reviewed, summarizing most recent data from the literature and with illustrations. Pseudocyst lesions include the aneurysmal bone cyst, the solitary bone cyst and Stafne's lacunae. Non-odontogenic cystic lesions, characterized by the presence of a non-odontogenic epithelial lining, are represented by the nasopalatin cyst, the nasoalveolar cyst and an entity currently covering globulomaxillary, midline palatin, midline mandibular and midline alveolar cysts.
The osseous tumors of the jaw bones are relatively rare but very oft malignant. This work analyses the different epidemiological, clinical, radiological, histological and therapeutic features of the benign and malignant osseous tumors of the jaw bones, with regard to the most recent literature. The described benign tumors are the osteoma and osteomatosis, the osteoblastoma and osteoid osteoma, the desmo-osteoblastoma and the exostosis. The osteosarcoma is the unique malignant osseous tumor encountered.

The records of 63 patients having had ultrasound examinations with grey-scale B-mode scanners have been reviewed, to determine what contribution ultrasound made to the diagnosis of superficial maxillofacial masses, when compared with clinical examination and other methods of investigation. Most of the ultrasound parameters described in the literature are found in the cases we have examined. Despite the fact that the ultrasound image is often compatible with the disease, diagnosis using ultrasound was much less accurate than expected. From this series, it is concluded that ultrasound examination is not recommended for the diagnosis of all maxillofacial pathology, especially when the echographist has no special experience in this field of pathology, when ultrasound findings are not correlated with clinical ones, and when the ultrasound report is not precise and exhaustive.
