[Lacrimal sac melanoma].

RESULTS: Mean stage (NOSPECS classification) at time of surgery was 4.5 (range 2-6). Mean stage postoperatively was 2.4 (range 0-5). Comparison of the mean stages showed significant improvement of ocular protrusion: 1.55 (range 1-2) postoperatively versus 2.4 preoperatively. Among the patients with optic neuropathy (stage 6, n=12), 83% (10/12) normalized PEV with normal or clear improvement in visual acuity three months postop. Diplopy remained unchanged in 45% (5/11) and improved in 45% (5/11), worsening in one patient. Clinical regression of the exophthalmia, irrespective of the intensity initially, was noted in 93% of patients at six months postop. All patient had overall improvement in the position of the eyelids at rest..

[Inflammatory myofibroblastic pseudotumor of the tongue].

INTRODUCTION: Inflammatory myofibroblastic tumor (IMT) is a new entity recently described, first in the lung. IMT are found throughout the body. CASE: We report a very rare tongue localization in a 22-year-old white woman. After a first diagnosis of fibrosarcoma, a new examination of the slide and immunohistochemical examination led to the definitive diagnosis of inflammatory myofibroblastic tumor of the tongue and not fibrosarcoma. DISCUSSION: IMT are rarely encountered in the head and neck region. Only 2 cases of IMT of the tongue have been reported in the world literature. Diagnosis of IMT is immunohistochemical. Spindle cells were reacted for smooth-muscle actin and vimentin. Treatment is surgical. The contribution of radiotherapy is not clear because of the small population of patients studied.

[Teratoid cyst: a rare tongue tumor in children].

BACKGROUND: Dermoid cysts are rare benign tumours (only 20 cases have been reported) with 3 different histological types. Only 5 cases of teratoid cyst of the tongue have been described in the world literature, characterized by a respiratory cilied epithelium. OBSERVATION: We report the sixth case, in a one-year-old boy with a macroglossia and permanent protrusion of the tongue. Ultrasonography showed a kystic, ovoid, homogeneous cyst. Treatment was a surgical resection. DISCUSSION: This case is similar to the other cases reported in the literature.

[The C0 line: from Delaire's analysis of craniofacial structure to modeling it on a computer spreadsheet].

BACKGROUND: We developed a computer spreadsheet allowing mathematical modelization of Delaire's craniofacial architecture analysis. METHOD: An orthonormed drawing field was defined from the classical C1 line and the new C0 line. The cartesian coordinates defined anatomic points in this orthonormed field. Lines were drawn from the coordinate equations defined on the basis of the laws of plane geometry. These formulae were then entered into the spreadsheet. RESULTS: The spreadsheet automatically calculates the line equations, the angles separating these lines, and the coordinates of the constructed points, in the defined orthonormed field. This calculation is achieved using the coordinates of the user-measured anatomic points. A new order in line drawing allows simplification of manual drawing. DISCUSSION: We present the advantages and inconveniences of this new method which does not modify the final drawing result nor the interpretation of Delaire's analysis.
