[Papillary carcinoma arising from dyshormonogenetic goiter]. / Cancer papillaire sur goitre dyshormonogénétique.

INTRODUCTION: Dyshormonogenetic goiter is a genetically determined thyroid hyperplasia due to an enzyme defect in thyroid-hormone synthesis. Malignant transformation is one of the most serious complications, rarely reported in the literature. OBSERVATION: We report a new case of a 13-year-old boy with goitrous hypothyroidism who consulted for a voluminous goiter. Total thyroidectomy was performed. Histopathological examination revealed multiple foci of papillary carcinoma with a lymph node metastasis. CONCLUSION: Dyshormonogenetic goiter is a rare entity, representing one of the causes of congenital hypothyroidism. It is morphologically characterized by architectural and cellular pleomorphism that may mimic thyroid malignancy and cause difficulties in differential diagnosis.

[Feminizing testicular syndrome with multiple hamartomas and bilateral paratesticular leiomyomas]. / Syndrome du testicule féminisant associé à des hamartomes multiples et à des léiomyomes paratesticulaires bilatéraux.

INTRODUCTION: Complete androgen insensitivity syndrome or testicular feminization syndrome (TF) is the most common form of male pseudohermaphrodism, caused by a failure of androgen receptor binding. Patient with male genotype 46 XY, has a female morphotype with well developed external sexual organs. EXEGESIS: - We report the case of a 29 year-old girl with a TF syndrome discovered during the exploration of a primary amenorrhoea. Bilateral orchidectomy was performed. The testis were immature; they showed bilateral leiomyoma of the tunica albuginea and multiple hamartomas on the right side. CONCLUSION: Benign tumors are developped in 80% of cases of TF and they are generally hamartomatous nodules of testis. Association of paratesticular leiomyoma to synchronous hamartoma has never been described, its histogenesis is discussed.
