RESUMO
Over one hundred cases of carcinomas located on the thyroglossal duct have been reported worldwide. Most of these tumors originally were differentiated thyroid cancers. Their biological behavior is the same as that of tumors of the thyroid gland itself. On the basis of one case discovered in an 11-year-old girl, who presented with regional and systemic metastases, we discuss the various aspects of their origin, diagnosis and treatment. As far as the latter is concerned, we think that these tumors can not always be treated by exeresis of the thyroglossal duct. On the basis of the analysis of situations in which these tumors may be encountered, we propose a carcinological surgery, which might possibly be more aggressive, on the thyroid and cervical lymphatic tissues.

In this article we present the tenth case, according to the literature, of adenocarcinoma occurring at a long standing ileostomy originally performed for ulcerative colitis. Study of this and previous cases demonstrates common factors such as a previous history of ulcerative colitis, a long interval until the appearance of symptoms, together with a similar clinical and pathological characterisation with invasion of neighbouring skin layers close to the ileostomy. Several pathogenic hypotheses are considered. We believe that local excision in oder to obtain the diagnosis is a better option than a sampling biopsy and that surgery should include a wide resection of the abdominal wall and intestine in order to comply with therapeutic criteria in malignant disease.
