1. [Therapeutic approach of differentiated thyroid carcinoma in children and adolescents].
Diferentiated thyroid cancer is uncommon in children and adolescents. It presents as a solitary thyroid nodule, as multinodular goiter, or as a neck mass that is noted accidentally by the patient, the family or by the physician. Surgery is the treatment of choice and most of the specialists consider that total thyroidectomy with central cervical lymph nodes dissection must be applied in all patients. Some specialists prefer a more conservative surgical treatment in order to avoid complications. Postoperatively, ablation treatment with iodine-131, for the eradication of the remaining normal or malignant thyroid tissue is indicated in the majority of patients. Thyroid hormone is administered for life. Follow-up is continued for many years.
2. [Cutaneous melanoma; diagnostic procedures and their evaluation in diagnosing and mapping sentinel nodes. Part 2].
The second part of this review describes the advantages, and evaluates the radionuclide-guided methods for sentinel lymph node localization and also evaluates the intraoperative application of the blue dye technique in melanoma. By combining the two techniques, the detection rate rises to 96%-98%. The presence of cancer cells in the sentinel node is histopathologically shown by using hematoxylin-eosin and by using sensitive techniques for the detection of micrometastases. Immunohistochemical tech-niques specific for epithelial markers and polymerase chain reaction examination are also applied. Sentinel lymph node biopsy suggests whether regional elective lymphade-nectomy shall be performed.
3. [Radiological assessment of invasion of the mandible by squamous cell carcinomas of the oral cavity].
Three cases of invasion of the mandible by squamous carcinomas of the oral cavity are presented in this study. The current literature is reviewed and the diagnostic capabilities of contemporary imaging methods are emphasised. The detection of the location and extent of the possible infiltration of the mandible is a determinant factor concerning the choice of treatment and prognosis.

An unusual case of pleomorphic adenoma displaying numerous horny pearls is described. The tumour arose in the right lateral lingual border of a 33-year-old man. In many pearls the cores were organized in two separate portions with distinct structural and histochemical features. The narrow peripheral portion had a compact structure and was rich in keratin since it contained cystine and was coloured with acid dyes of intermediate molecular size. The central portion was characterized by a loose texture and its histochemical profile (affinity for acid dyes of large molecular size, weak alcianophilia, vivid binding of colloidal iron) resulted from the existence of acidic mucosubstances in the cell coating of the neoplastic keratinized cells. These observations suggest that certain similarities exist between the processes of normal keratinization and squamous metaplasia in pleomorphic adenoma.
