Quistes retro-aeeolares en adolescentes: aspectos clínicos y ultrasonograficos / Retro-areolar cysts in adolescents: clinical and ultrasonographic aspects

Retroareolar cysts are common in pre and postmenarchic girls. Boys are rarely diagnosed with this condition. They correspond to cystic dilatations of the accessory mammary glands that open along with a sebaceous gland at the areola and can be single or multiple, uni or bilateral, palpable or incidental findings on ultrasound. They have variable morphology, thin walls, anechogenic content, sometimes calcic sediment can be observed in their lumen. Infected cysts present enlarged, hypervascularized walls; their content is echogenic, avascular and the adjacent tissue is hyperechogenic, with increased vascularization at color Doppler. If not treated, may become retroareolar abscesses. Inflamatory complications are treated with anti-inflamatory drugs and/or antibiotics. No diagnostic biopsy or puncture aspiration is required, since they are spontaneously drained at the areola. In order to appropriately advise patients and families, it is necessary to have knowledge of both the medical and the ultrasonographic aspects of them and their complications.

Los quistes retroareolares son frecuentes en niñas pre y postmenárquicas. Raramente se diagnostican en el varón. Corresponden a dilataciones quísticas de glándulas mamarias accesorias que se abren junto con una glándula sebácea en la areola, pueden ser únicos o múltiples, uni o bilaterales, palpables o hallazgos incidentales en ecografía. Los no complicados tienen morfología variable, paredes delgadas y contenido anecogénico, pudiendo observarse sedimento calcico en su lumen. Los complicados presentan paredes engrosadas, hipervascularizadas, con contenido ecogénico, avascular, tejidos adyacentes hiperecogénicos y aumento de la vascularización al Doppler color. Sin tratamiento, pueden transformarse en abscesos retroareolares. La complicación inflamatoria se trata con antiinflamatorios y/o antibióticos. No requieren biopsia diagnóstica ni punción evacuadora, puesto que se drenan espontáneamente a la areola. El conocimiento del cuadro clínico y su aspecto ul-trasonográfico permitirá orientar adecuadamente a los pacientes y sus familias.

Ductographic Findings of Breast Cancer

Ductography has become the gold standard for the evaluation of patients exhibiting pathologic nipple discharges. In nine patients (age range, 29-67 years; median age, 51 years) with invasive (n=5) or intraductal (n=4) cancer, ductographic findings were recorded, then correlated with mammographic and sonographic findings. Common ductographic findings included complete ductal obstruction, multiple irregular filling defects in the nondilated peripheral ducts, ductal wall irregularities, periductal contrast extravasation, and ductal displacement. Faint microcalcifications or ill-defined masses, which were not opacified by contrast material, were often discovered adjacent to ductal abnormalities. Mammographically and sonographically occult diffusely spreading intraductal cancers often manifested as pathologic nipple discharge. In such cases, meticulous ductographic examinations and interpretations were crucial in order not to miss breast cancers.
