[Congenital granular-cell tumor].

Tumour consisting of nodes (15 x 10 x 8 mm, 2 cm and 0.3 cm in size) on the alveolar processes of the maxilla and mandibula is found in a newborn. Histological diagnosis is granular-cell myoblastoma.

[Carcinoma cuniculatum. Apropos of 4 cases with orofacial involvement].

Carcinoma cuniculatum, a rare variant of verrucous carcinoma, was first described in the foot. The authors report 4 cases of uncommon localizations of this tumor, involving oral cavity and face, 3 of them having a 6-year follow-up. The specific histological and clinical features of this tumor are remembered and the difficulties of its diagnosis are emphasized. This slow-growing, ulcerated proliferation, invading the surrounding tissues, is often responsible for chronic suppuration, but very rarely metastasizes to the regional lymph nodes. The surgical treatment consists in a wide excision; neck dissection is theoretically useless, and radiotherapy is strictly contraindicated because of the risk of transformation into an anaplasic carcinoma. For all these reasons, carcinoma cuniculatum must be considered as an anatomoclinic entity, and deserves to be known by the clinicians and the pathologists.

Adenomatoid odontogenic tumour (adenoameloblastoma)--a review.

The adenomatoid odontogenic tumour (AOT) is a rare benign neoplasm of odontogenic origin. A review of the available published literature reports on AOT from Africa reveals that 33 cases appear to have been reported and that the tumour tends to occur in young patients, from 10-28 years with a mean age of 16.2 years. Females are affected more than males, with a female:male ratio of 3:2. 65.6% of cases were in the maxilla and 34.4% in the mandible, the majority of which (92.3%) are located in the anterior region of the jaws. 66.7% of the cases are associated with unerupted teeth. Clinically, AOT shows increasingly painless swellings which may eventually cause facial deformity. Tentative clinical diagnosis based on radiology is not pathognomonic for AOT; histopathological confirmation is necessary since incorrect diagnosis may lead to mutilating surgery whereas the lesion is benign with limited growth potential and treatment requires only simple surgical enucleation. Recurrence is rare.

[Osseous metastases in upper and lower jaws].

18 cases of metastases to the jaws in the last 10 years obtained from the Clinic of Maxillofacial Surgery and the Department of Pathology, University Hospital Zürich, are described. They were seen in patients with carcinoma of the breast, lung, prostate gland, uterus and seminoma of the testis. In 16 cases the metastases were situated in the mandible, in 2 cases in the maxilla. The average age of these patients was 61.6 years with no sex predilection. The initial symptoms were pain swelling. In 4 cases a pathologic fracture was diagnosed. The majority of the metastatic lesions are osteolytic in nature. The metastases were diagnosed, in average 3.3 years after diagnoses of the preliminary tumor. In 2 cases the metastases were diagnosed before the occult primary tumor. Death usually ensues 1 year after diagnoses.

Multilobular osteochondrosarcoma of the canine skull: 16 cases (1978-1988).

The medical records of 12 dogs with multilobular osteochondrosarcoma (MLO) and examined at the Veterinary Teaching Hospital, Colorado State University from August 1979 to January 1987 were reviewed. Medical records of 1 dog with MLO and 3 dogs with MLO examined at the Ontario Veterinary College, University of Guelph and the Veterinary Medical Teaching Hospital, University of California, Davis, respectively, were also reviewed and included in the study. The mean age of affected dogs was 7.5 years, a single breed did not appear to be overrepresented, and males were affected as frequently as were females. All of the primary lesions affected either the mandible, maxilla, or cranium. Excision was the only treatment in 11 dogs, 2 dogs had radiotherapy in addition to excision, and 1 dog had radiotherapy and chemotherapy after excision. Twelve treated dogs had follow-up information available. Of the 12 treated dogs, 7 (58%) had local recurrence, with median time to recurrence of 14 months. Seven dogs (58%) developed metastatic disease after treatment, with median time to metastasis of 14 months. The median disease-free interval was 12 months, and the median survival time was 21 months. Excision with histologically complete surgical margins appeared to offer good opportunity for long-term tumor control. The role of adjuvant chemotherapy and radiotherapy in the management of MLO remains unclear.

[Esthesioneurocytoma of the upper jaw].

The authors present a new case of aesthesioneurocytoma with an atypical localisation. They review the clinical, radiological and histological features of these tumours. They stress the importance of mixed surgical/radiotherapy treatment and suggest the desirability of routine estimation before and after treatment of U. M. A. and U. V. A. Dopamine in the urine.

[The maxillo-mandibular desmoid fibroma. Synthesis of knowledge about a rare entity. Apropos of 3 cases].

Three cases of maxillo-mandibular desmoplastic fibroma are added to the 41 cases already described in the literature. A synthesis of the actual knowledge concerning the tumor is presented. The tumor is mainly composed of fibrous tissue with bundles of mature collagen, and can be easily confused with a low grade fibrosarcoma. Most of the patients are caucasian males. It is a young people tumor (0 to 30 years) with a peak between 6 to 15 years. The mandible was involved in 36 cases and the maxilla in 8 cases. The left side was involved in a ratio of 2 to 1 compared to the right side. In the mandible, the tumor was observed most frequently in the body and at the angle of the jaw. Pain or tumefaction were the most prevalent clinical features. The etiology of the tumor is unclear but trauma is often implicated. When the treatment is conservative, recurrences are frequent. The maxillo-mandibular desmoplastic fibroma should be recognized early to avoid local tissue destruction.

Maxillary resection for odontogenic myxoma: report of case.

A brief overview of the literature and a report of a resection of an odontogenic myxoma involving the right maxillary sinus are presented. We believe that a lesser surgical procedure might have compromised the patient's health by possible further surgical procedures with a resulting greater facial deformity or morbidity. Through careful evaluation and planning, problems of management were minimized.

[The combined use of cryosurgery and solcoseryl in treating malignant neoplasms].

Antitumour efficacy of a combined use of cryosurgery and solcoseryl in mice with Lewis carcinoma was studied. Solcoseryl improves results of cryosurgery. An increase in antitumour effect with a combined use of cryodestruction and solcoseryl is supposed to be followed by the rise of oxygen tension in tissues. Solcoseryl injection followed by cryosurgery of cancer of mouth cavity mucosa in patients considerably accelerates the wound surface regeneration. Thus solcoseryl increases the treatment efficacy of the cryosurgical method.

[Aneurysmal cysts located in the maxilla or mandible (author's transl)].

Aneurysmal cysts of the mandible and maxilla are rare conditions, though not exceptional, which are seen in particular in the child and adolescent. A part from facial asymmetry and tumefaction, it is rare to find other clinical manifestations. No neurological signs were seen in the present study. An aneurysmal cyst gives a radiological appearance of non-characteristic lysis compatible with a large range of diagnoses. Histological study permits early diagnosis but must always involve the whole specimen with careful examination to detect any other associated lesion. The pathogenesis of the condition remains obscure and, at the extreme, it may be questioned whether the aneurysmal cyst is a separate entity or a particular form of chronic osteopathy.
