Carcinomas of the thyroid with unusual presentation. About two cases.

Two cases of thyroid carcinoma with unusual presentation are reported. In the first case, a follicular carcinoma was associated with hyperthyroidism from a hot nodule located in the same lobe. This condition is not so infrequent as indicated by the literature and should warrant pathological examination at the time of excision of the hot nodule. In the second case, both anaplastic and follicular carcinomas were coexisting in the same tumour of a young adult. This occurrence is rather exceptional in the early period of life and is usually the fact of elderly people with long-standing goiters. The favourable outcome of this patient is also contrasting with the bad prognosis associated with anaplastic carcinoma of the thyroid. Another interesting feature is the existence of an anaplastic carcinoma of the thyroid in a family member of this second case.
