ICEECE2012 Poster Presentations Thyroid cancer (108 abstracts)
Department of pathology, Algiers, Algeria.
Introduction: Apart from pulmonary and bone localizations, distant metastases from well differentiated thyroid carcinomas are very rare. Among them the adrenal ones are exceptional, and have generally a poor prognosis. The proof of the thyroid origin is not easy except if there is a histological confirmation by a CT guided biopsy of the adrenal tumor as in this observation
Observation: A woman aged 56 was referred to our unit for pulmonary metastases of a well differentiated thyroid carcinoma whose diagnosis was made by transthoracic puncture of one of the pulmonary nodules that reacted with anti thyroglobulin antibodies. In fact she was operated on twice (in 2005 and 2009) for thyroid disease diagnosed as an oncocytic metaplasia, and then she was lost in sight. During her hospitalization numerous bone and pulmonary metastases were found. Echosonography and CT scan showed two larges adrenals. A CT scan guided biopsy of the left adrenal confirmed the thyroid origin.
Conclusion: Adrenal metastases due to follicular thyroid cancer are exceptional. They may be uni or bilateral. Their prognosis is poor as they are diagnosed at the late stage of the disease as in our observation. A CT scan guided biopsy (when possible) is very helpful for the histological proof.
