[Primary solid tumors of the epididymis. Apropos of 4 cases of benign tumor and one case of malignant mesothelioma].
Based on a series of 5 tumours of the epididymis, the authors recall the relative frequency of primary solid tumours of the epididymis. They present 2 benign mesotheliomas and discuss the various histogenetic theories for their development, one fibroma, one haemangio-fibro-leiomyoma and one malignant mesothelioma of the cord, invading the epididymis. These are rare tumours (Broth's review of the literature revealed 278 cases in the world, consisting of 209 benign tumours (75%) and 69 malignant tumours (25%). The most frequent benign tumour is the mesothelioma (75% of the benign tumours), formerly referred to as an "adenomatoid tumour". Its histogenesis is still controversial (epithelial or mesothelial origin). The mesothelial theory is the more widely accepted. According to the majority of authors, malignant mesothelioma of the epididymis does not exist, but our case of malignant tumour questions this concept. The other tumours consist of benign and malignant mesenchymal, epithelial or dysembryoplastic tumours. The borderline with spermatic cord tumours is not always easy to define. The authors recall the value of comparative scrotal ultrasonography for the topographical diagnosis of tumours of the epididymis and testicular tumours and the differential diagnosis with certain epididymal cysts.
