Muscular hamartoma of the breast: a rare breast lesion containing smooth muscle
Hamartoma of the breast is an uncommon entity, usually presenting as a well-demarcated breast mass. Microscopically, the lesion is composed of mammary glandular component, fibrous stroma, adipose tissue, and smooth muscle in variable proportions. Among the variants of breast hamartoma, muscular hama...
