GOMEZ DELGADO DE LA FLOR, Mario  and  HUAYANAY SANTOS, Jorge Luis. Mamografía y Ecografía en la evaluación de las lesiones no palpables de la mama y su correlación anatomo-patológica. Rev Med Hered [online]. 2002, vol.13, n.4, pp.135-139. ISSN 1018-130X.

Objective: To evaluate the mammographic and ultrasonographic characteristics of non palpable lesions of the breast (NPL) and to establish their anatomical-pathological correlation. Material and Methods: Descriptive study retrospective type carried out on the Instituto de Enfermedades Neoplásicas where patients with NPL detected by mammography and meet all inclusion criteria were included among March 1, 1997 and February 28, 1999. Results: 104 patients were studied with NPL. 22.1% of the NPL were breast cancer. 53 gave mass effect in mammography: oval form 18 benign (B), 1 malignant (M) (p <0.05), distortion architecture 1 B, 8 M (p <0.05), speculed margins 1 B, 10 M (p <0.05), 51 were isolated microcalcifications (MC), 3 masses associated to MC, 48 that gave mass effect were evaluated by ultrasonography : defined border 20 B, 1 M (p <0.05), spiculed 0 B, 6 M (p <0.05), heterogeneous echoes 4 B, 8 M (p <0.05), homogeneous hypoechogenic echoes 30 B, 2 M (p <0.05). Conclusions: In the lesions that gave mass effect on mammography the oval form and bounded margins were benign, the distortion of the architecture and the spiculed borders were associated with malignancy. In the lesions evaluated by ultrasonography the defined borders and internal homogeneous hypoecoghenic echoes were benign and the spiculed borders and heterogeneous echoes were malignant.
