Abstract

We illustrate the sonographic findings of malignant breast masses that can mimic a cystic component with pathologic correlations. The disease entities presented in this study include infiltrating ductal carcinoma, ductal carcinoma in situ (DCIS), papillary carcinoma, mucinous carcinoma, medullary carcinoma, metaplastic carcinoma, and a malignant phyllodes tumor. Malignant masses with a cystic component are often characterized by well-circumscribed round, oval, or lobular masses, thereby appearing benign on ultrasonography. On pathology, the cystic component of a malignant mass is identified by cystic degeneration, hemorrhage, necrosis, or ductal dilatation. If the mass is well-circumscribed with a cystic component, a biopsy should be considered in the analysis of the solid component within a mass.

초음파 검사에서 낭성 부위를 가지는 것으로 보이는 유방암들을 병리소견과 함께 비교해 보고자 한다. 침윤성 관상피암, 관상피내암, 유두상암, 점액암, 수질암, 화생성암, 악성 엽상육종들이 포함된다. 낭성부위를 가지는 악성종양은 경계가 잘 그려지는 둥글거나, 난형, 혹은 소엽상 종괴로 초음파 소견상 양성 종양과 유사하게 보인다. 병리적으로 악성종양의 낭성 부위는 낭성 변성, 출혈, 괴사 혹은 유관 확장 등이었다. 경계가 잘 그려지는 낭성 부위를 가지는 종괴는 종괴 내 고형성분의 특징을 잘 분석하여 조직 검사를 고려해야 한다.
