[Sarcoidosis of the thyroid: A case report]. / La sarcoïdose thyroïdienne: à propos d'un cas.

OBJECTIVE: To present a case of thyroid sarcoidosis revealed by a multinodular goiter and cervical and mediastinal adenopathies. METHODS: We summarize the clinical presentation of a thyroid sarcoidosis. A review of literature regarding this topic is also presented. RESULTS: A 48-year-old woman presented dysphagia without dyspnea. Clinical and radiological explorations find a multinodular goiter with cervical and mediastinal adenopathies. The symptomatic side of the goiter and the association with adenopathies justify the surgery. Total thyroidectomy and mediastinal lymphadenectomy are processed. Histopathological examination of the thyroid reveal a goiter without malignity, a vesicular nodule, and non necrotizing granulomas consistent with sarcoidosis, as in the adenopathy. CONCLUSION: The interest here, is the difficulty to make the diagnostic without histopathology, between a thyroid cancer with lymphadenopathies and extrapulmonary sarcoidosis (involving thyroid and adenopathies).

[Covering of parotid and cervical lymph nodes metastasis of cutaneous squamous cell carcinoma of the head, about 18 cases]. / Prise en charge des métastases cervico-parotidiennes des carcinomes épidermoides de la face, discussion à partir d'une série de cas.

AIM: To describe 18 cases of patients treated for advanced cutaneous squamous cell carcinoma (CSCC) of the head metastasing to cervical lymph nodes and parotid gland. To estimate their survival and the risk factors of metastases. PATIENTS AND METHODS: 18 cases of patients affected by CSCC of the head, metastatic to parotid and cervical lymph nodes were afterward analyzed. Two populations were differentiated: the patients already treated for their CSCC, with secondary appearance of metastases in the Population A, the patients by whom the metastase is concomitantly discovered to the CSCC in the Population B. RESULTS: The treatment consisted of a parotidectomy and neck dissection, possibly associated with excision of the primary tumour. Adjuvant radiotherapy was systematic. Metastatic progression was on lungs most of the time (57%), in patients of the population B (80%), or of whom primitive CSCC was of bad forecast (group 2) (78%). The mortality was bound to the complications induced by distant metastases (63%), at 5 years it was superior in the population B (100%) than in the population A (77%). CONCLUSION: CSCC of the head, metastatic to parotid and cervical lymph nodes have a severe prognosis for survival in spite of an optimal curative treatment applied to fragile old patients.
