This is a 29-year-old female with a palpable mass in the left breast. How would you evaluate this young woman? How would you characterize the sonographic findings? Does the mass appear benign, malignant or indeterminate? C'est une patiente de 29 ans se présentant avec une masse palpable dans le sein gauche. Comment évalueriez-vous la pathologie de cette jeune femme? Comment vous interprétez les résultats de l'examen échographique? La masse est elle bénigne, maligne ou indéterminée?

Ultrasound shows a mass that is sharply marginated, thin- rimmed, oval with long axis parallel to the skin. The mass is hypoechoic, composed of surrounding fibroglandular tissue. Internal echoes within the lesion are somewhat inhomogeneously distributed. Acoustic through transmission is present. These findings are typical of a fibroadenoma. Histology : Fibroadenomas. L'échographie montre une masse solide ovalaire à grand axe parallèle à la peau, a contours nets, de structure hypoéchogène, de contraste modéré par rapport au tissu environnant. Elle est homogène avec un faible renforcement postérieur en arrière . ces signes sont caractéristiques d'un adénofibrome. Histologie : Adénofibrome.

Fibroadenomas are the most common tumor of youth and early adulthood. With increasing age, they may hyalinize or calcify. Fibroadenomas are composed of the normal tissues of the breast just in an abnormal formation; thus, they can have carcinoma within them. But the risk of cancer within a fibro adenoma is no greater than that of other breast tissue.
Fibroadenomas are estrogen stimulated and are frequently identified in women of reproductive age, usually between the ages of 15 and 35 years, with a mean age of 30 years. Because they are hormonally stimulated, they can grow rapidly in pregnant women. Rarely are new fibroadenomas found in postmenopausal women with or without HRT. These masses, as with any new solid mass in a postmenopausal woman, should be considered highly suspicious for cancer, and tissue diagnosis is essential.
Juvenile fibroadenomas are found in adolescents and can have extremely rapid growth, to the point of deforming the breast and causing nipple displacement. They may be multiple and bilateral. Sonographically, they are indistinct from other fibroadenomas. When large, these masses can concurrently be called juvenile and giant.

Sonographic Findings :
Fibroadenomas are smooth or macrolobulated masses that are more wide than tall. Usually they measure less than 3 cm. These lesions displace rather than infiltrate surrounding tissue, making them well-marginated masses. They are typically homogeneous with low-level internal echoes but can show areas of cystic necrosis if they outgrow their blood supply. Posterior acoustic enhancement is present in a large percentage of fibroadenomas, although any acoustic transmission pattern may be present in uncalcified fibroadenomas, including posterior acoustic shadowing.. "Popcorn" calcifications can form, and sonographically these masses may completely attenuate the ultrasound beam, producing significant posterior shadowing. An ultrasound examination may not be of assistance in these cases. Peripheral vascularity may be visualized with Doppler.
