“…To make the diagnosis, ultrasound has a prominent place in the detection and monitoring of dermoid cysts [5]. However, the limitation of ultrasonography is explained by its sensitivity, which does not allow to distinguish a secondary transformation from a TKM [6], although our patient did not benefit from a CT scan, This examination allows detection and characterization based on the detection of fat density in 88% of cases and on the identification of a Rokitanski protuberance in 91% of cases, easily recognized by its rounded shape, with clear internal borders, containing teeth, adipose tissue and connective tissue taking up the contrast medium late . On MRI, the appearance of the dermoid cyst is considered less characteristic, the fat, but also the hemorrhagic lesions appear hyperintense in T1, the introduction of the fat suppression sequence allows them to be differentiated [7].…”

“…15 The great frequency of malignant transformation is reported to be between 45 and 60 years old. 13,16,17 The diagnosis of malignant transformation of mature cyst teratoma is difficult in preoperative. No diagnosis criteria can confirm the malignancy before the anatomopathological study.…”

“…The main criteria leading to the malignant transformation are the patient age and the tumor size. 13,16,17 In general, malignant teratoma has a more aggressive clinical course than mature cystic teratomas. 18 Due to the rarity of MT to SCC and the complex components of MCTs, preoperatively distinguishing between these 2 conditions is extremely difficult.…”

“…Dans 1 à 2 % des cas, une transformation maligne de cette pathologie survient [ 1 , 2 ]. L’âge de survenue dece cancer chez notre patiente a été de 58ans ce qui correspond à l’âge moyen de survenue rapporté par plusieurs auteurs et qui est de 54 ans [ 5 – 7 ]. Moins observé en périodepériménopausique, il est fréquent chez la femme ménopausée depuis quelques années.…”

“…Ils rapportent que l’âge supérieur à 40 ans est l’un de ces critères avec un pic d’incidence de cancérisation situé entre 45 et 60 ans [ 2 ]. La taille supérieure à 99 mm, l’augmentation de la taille d’un kyste dermoïde en période ménopausique ou toute croissance supérieure à deux centimètres par an en période d’activité génitale doivent aussi faire suspecter la transformation maligne d’un kyste dermoïde [ 5 ]. Parmi les éléments biologiques étudiés, Seule l’analyse du squamous cell carcinoma (SCC) pourrait apporter un indice quant à la transformation maligne du kyste dermoïde.…”
