Where is a sebaceous cyst typically located?

Explanation:
Sebaceous (epidermoid) cysts are benign skin lesions that arise from blocked sebaceous glands or hair follicles and reside in the dermis or subcutaneous tissue just beneath the skin. Because of this origin, they sit superficially, near the skin surface, rather than deep inside breast tissue or within muscle. In breast ultrasound, this means you’d expect a well-defined lesion that lies just under the skin/dermis, not a lesion within the breast parenchyma, pectoralis muscle, or the nipple-areolar complex. The other locations would suggest a different process related to deeper breast structures or skin involvement.
