Résumé

Introduction

Les tumeurs testiculaires à cellules de Leydig (TTCL) sont rares, elles représentent entre 1 et 3 % de l’ensemble des tumeurs testiculaires, ce sont les plus fréquentes des tumeurs des cordons sexuels et du stroma. Ces tumeurs se développent le plus fréquemment (55 %) chez les sujets jeunes de 15 à 35 ans, mais elles peuvent se voir aussi chez les enfants lors de la première décennie (20 %) et chez les hommes après 50 ans (25 %). Le mode de révélation le plus fréquent chez l’adulte est la gynécomastie, par contre chez l’enfant, c’est la pseudopuberté précoce isosexuelle. Elles posent le problème de leur diagnostic biologique devant des formes non palpables et du choix de leur traitement chirurgical en raison de la difficulté diagnostique entre les formes bénignes et malignes.

Matériel et méthodes

Nous rapportons quatre présentations différentes de cette pathologie dont les paramètres étudiés seront l’âge, le mode de révélation, le profil hormonal, le type de traitement et le mode évolutif.

Résultats

L’âge moyen de nos patients était de 37 ans et demi. Le mode de révélation était deux fois sur quatre en rapport avec une grosse bourse unilatérale, une fois pour grosse bourse bilatérale, une fois en rapport avec une gynécomastie. Dans tous les cas, la testostérone était normale ou basse et l’estradiol normal ou élevé. Les quatre patients ont subi une orchidectomie associée à une énucléation controlatérale chez un seul des patients. L’évolution était favorable pour tous nos patients, avec un recul moyen de 15 mois.

Conclusion

Le but de cette revue est de présenter, sur la base de quatre observations cliniques différentes et de l’analyse de la littérature, les différents aspects cliniques, biologiques, radiologiques pathologiques et thérapeutiques des TTCL.

Abstract

Introduction

Leydig cell tumors of the testis are uncommon, and represent 1 to 3% of all testicular tumors, it’s the most common of sex cord stromal tumors. They can be found in all age groups, but they mainly occur in subjects aged 15 to 50 years (50%), 25% occurring in older men and a little less than 20% in children aged 5 to 9 years. The most common revealing symptom is gynecomastia in adults, whereas in children it is isosexual pseudo-precocious puberty. They pose a problem during diagnosis, nonpalpable tumors, and during the choice of surgical treatment, because it is difficult to make a clear distinction between benign and malignant tumors.

Material and methods

We describe four different presentations of this disease. The parameters studied were: age, revealing symptom, hormonal profile, type of treatment, and mode of evolution.

Results

The average age of our patients was 37.5 years. The first revealing symptom was a unilateral increasing size of purse in two cases, a bilateral increasing size of purse in one case, and gynecomastia in the last one. In all cases testosterone was normal or low, and oestradiol was normal or elevated. Our four patients underwent an orchidectomy, associated with an enucleation of the contralateral testis in only one case. A favorable evolution was observed in every case for a mean follow-up of 15 months.

Conclusion

On the basis of four different clinical observations and the analysis of the literature, the aim of this review is to present the various clinical, biological, radiological, pathological and therapeutic aspects of Leydig cell tumors of the testis.
