What is a well encapsulated mass?

A well-encapsulated mass refers to a distinct, clearly defined lump or growth that is surrounded by a capsule of fibrous tissue. This characteristic encapsulation often indicates that the mass is benign, as it suggests that it is contained and separated from the surrounding tissues. In medical imaging or pathology, well-encapsulated masses can be indicative of conditions such as lipomas or certain types of tumors, making their identification important for diagnosis and treatment planning.
