Summary
Metaplastic carcinoma is a rare tumour which is often confused with other benign and malignant pathologies. This heterogenous tumour characteristically contains areas of adenocarcinoma mixed with other non ductal mesenquinal tissue, generally with a spindle, squamous, or chondroid phenotype, or osseous differentiation. Although these tumours are large, at the time of diagnosis they don’t usually present with local or distant metasteses.
We analyze the clinical and pathological features with a follow –up series of 7 cases of metaplastic breast carcinoma.
The purpose of this study is to characterize the clinical course, treatment, and prognostic factors of this type of tumour.
Resumen
El carcinoma metaplásico es un tumor poco frecuente que a menudo se confunde con otras afecciones, tanto benignas como malignas. Es un tumor heterogéneo que se caracteriza por contener áreas de adenocarcinoma combinadas con otras de tejido mesenquimal no glandular, de fenotipo generalmente fusiforme, escamoso, condroide o con diferenciación ósea. A pesar de ser tumores de tamaño grande, en el momento del diagnóstico no suelen presentar afección metastásica axilar ni a distancia.
En este trabajo analizamos el comportamiento clinicopatológico y el seguimiento de 7 casos de carcinoma metaplásico mamario (CMM).
El objetivo de este estudio es caracterizar el curso clínico, el tratamiento y los factores pronósticos de este tipo tumoral.
