Myoid (muscular) hamartoma is a rare form of benign breast hamartoma composed of differentiated mammary glandular and stromal structures, fatty tissue and areas of smooth muscle from which its name originates. It is considered to be a variant of a mammary hamartoma. We report the clinical presentation, imaging appearances and treatment of the initial and recurrent presentation of this rare tumour in a 61year old female, which mimicked malignancy. Although rare, myoid hamartoma's can reoccur and when they do they imaging appearances of benign and malignant tumours can overlap tend to mimic malignancy and histological diagnosis is mandatory.
肌样（肌肉性）错构瘤是一种罕见的良性乳腺错构瘤，由分化的乳腺腺管和间质结构、脂肪组织和平滑肌区域组成，其名称即源于此。它被认为是乳腺错构瘤的一种变体。我们报告了一名61岁女性的这种罕见肿瘤首次及复发时的临床表现、影像学表现及治疗情况，其表现类似恶性肿瘤。尽管肌样错构瘤罕见，但可复发，复发时其影像学表现可与良性和恶性肿瘤重叠，易被误诊为恶性肿瘤，因此组织学诊断必不可少。
