Objetivos

Aportar nuestra experiencia en el estudio del carcinomaductal in situde la mama (CDis), correlacionando radiopatologicamen-te las calcificaciones vistas en la mamografía con su localización histo-lógica dentro del tumor.

Material y método

Se revisan retrospectivamente 20 casos deCDis, diagnosticados por calcificaciones en la mamografía, que repre-sentan un 81% (20/24) del total de CDis. Se analizan características ra-diológicas de las calcificaciones como forma de agrupación, numero,distribución, tamaño, forma y densidad. Anatomopatológicamente seclasifican en tres subtipos y se estudia la localización del calcio dentrodel tumor, Se correlacionan los datos histológicos con los manifesta-dos en la mamografía.

Resultados

En el análisis mamográfico la forma de agrupaciónmás frecuente fue la «focal no segmentaria» con un 65% (13/20) y elnúmero de microcalcificaciones de 5 a 10 con un 45% (9/20). Predo-minó la heterogeneidad de tamaño y forma (80% / 75%), y la morfolo-gía más frecuente fue la redondeada (65%). Histológicamente el 95%de las microcalcificaciones se identificaron dentro del tumor, corres-pondiendo en los tipos III a calcio en componente necrótico, y en lostipos I y II a calcio en las cribas o micropapilas del tumor. Se detectómultifocalidad y microinfiltración en los tres subtipos histológicos.

Conclusiones

Existe una buena correlación radiopatológica de lasmicrocalcificaciones en los CDis En los grados I y II las calcificacio-nes en la mamografía son predominantemente redondas y pequeñas, ehistológicamente se corresponden con depósitos cálcicos laminados opsamomatosos en las cribas o micropapilas del tumor. En el grado IIIlas calcificaciones son redondas o alargadas (moldeadas) y se corres-ponden con calcificación amorfa de material necrótico intraductal.

Objectives:

To contribute our experience in the study of ductal car-cinoma in situof the breast (DCis), correlating the radiological andpathological features of the calcifications detected by mammographywith their histological location within the tumor.

Material and methods

Out of 24 cases of DCis, 20 diagnosed onthe basis of calcifications detected on mammography (81%) were reviewed retrospectively. The authors assessed the radiological featuresof the calcifications such as cluster formation, number, distribution, size, shape and density. They were classified into three pathologicalsubtypes, and the location of calcium within the tumor was studied.The histological data were correlated with the mammographic findings.

Result

Mammography showed that «nonsegmented focal» clusterswere the most common type (13 of 20 cases) and that 45% of the tu-mors (9 of 20) presented 5 to 10 microcalcifications. Heterogeneity ofsize and shape predominated (80% and 75%, respectively), while 65%of the lesions had a round morphology. The histological findings sho-wed that 95% of the microcalcifications were located in the interior ofthe tumor, and consisted of calcium with a necrotic component in gra-de III lesions, and calcium in the cribriform cells or micropapillae ofthe tumors in grades I and II. Microfocality and microinfiltration weredetected in all three subtypes.

Conclusions

There is a good radiologic-pathologic correlation of mi-crocalcification in DCis. The calcifications observed in mammogramsfrom grade I and II lesions are predominantly round-shaped and small insize. Histological analysis identifies them as laminated or psammomatouscalcific deposits in the cribriform cells or micropapillae of the tumor. Ingrade III lesions, the calcifications are rounded or elongated, and corres-pond to amorphous calcifications comprised of intraductal necrotic tis-sue.
