[Thyroid papillary microcarcinoma. Salah Azaiz Institute experience].

The incidence of thyroid papillary microcarcinoma appears to be increasing and therapeutic modalities remain controversial. This retrospective study concerns 25 cases, from 1978 to 1999. The circumstances of diagnosis were: a cervicotomy for thyroid nodule (88% of cases), cervical node metastases (8%), and osseous metastases (4%). The sensitivity of ultrasounds was 22.2%, that of scintigraphy was 9.1% and that of extemporaneous histological examination was 18.2%. Multifocality was found in 16% of cases and bilaterality in 16.6%. Treatment modalities were guided by histological examination. Adjunctive radioiodine ablation was used for 20% of the patients. The treatment of the osseous metastases was completed with external irradiation. The average follow up was 4.8 years (4 months to 19 years), with a rate of survival without disease of 100%.

[Thyroid oncocytomas].

OBJECTIVE: Thyroid oncocytomas are rare tumors. They put problems of differential diagnosis enter malignant and benign forms. The modalities of the surgical treatment are controversial, in form as benign as malignant. Their prognosis is also debated. MATERIAL AND METHOD: Our retrospective study concerns 111 thyroid oncocytomas, so 6.5% of thyroid operated in our centre between 1981 and 2001. The sex-ratio of the patients was 0.16 with an average age of 41 years (15 to 72 years). RESULTS: All the fixed nodules, those associated to a recurrential paralysis, to tangible nodes or/and to microcalcifications on the radiography of the neck was malignant. Histological extemporaneous exam was not decisive in 16% of cases, among which 33% showed themselves malignant in the definitive exam, which put in evidence 9 carcinomas (8%). We treated benign oncocytomas by a loboisthmectomy for the isolated nodules, and the subtotal or total thyroidectomy for multinodular glands. For oncocytic carcinomas, we realized a total thyroidectomy with ganglionic taking and histological extemporaneous exam, followed by evidment in case of invasion (2 patients). For the 5 patients having presented a residual fixation, we obtained a white cartography after radioactive iodine administration. For the benign oncocytoma, we did ot notice any recurrences with an average drop of 28 months (2 months to 7 years). For carcinoma, 8 patients on 9 presented an actuarial survival without disease with an average drop of 44 months (18 months to 8 years). CONCLUSION: The diagnosis of malignancy of thyroid oncocytomas can be strongly evoked on however fickle clinical and radiological criteria; it can be eliminated only after definitive anatomo-pathological exam.

[Mucous malignant melanoma of the neck and face. Experience at the Salah Azaiz Institute (Tunis)].

The mucosal melanoma of the head and neck is rare and of late diagnosis. This retrospective study concerns 17 cases brought together in 30 years. Sex-ratio was of 1.1, the average age of 58 years. Tumoral seats were the following ones: nasal cavity and paranasal sinus (n = 10), nasopharyngeal cavity (n = 2), gingival seat (n = 2), palate (n = 1), laryngeal seat (n = 1), middle ear (n = 1). Tumoral extension was classified an follows: stage I: 52.9%, stage II: 17.6%, stage III: 29.4%. Melanomas were achromic in 23.5% of cases. On the therapeutic plan, 47.1% of the patients were treated in a purpose palliative because of the importance of the tumoral extension. Seven patients (41.2%) were treated surgically; three among them received an additional radiotherapy for an insufficient tumoral excision or adenopathy in break capsular. Two patients (11.8%) were treated by exclusive radiotherapy. The rates of survival were 17.6% in 2 years, and 5.9% in 5 years. The average duration of survival was of 18.1 months. The causes of failure were essentially local and metastatic.
