proliferativas

Proliferativas is the plural feminine form of the Spanish adjective proliferativo or proliferativa, used to describe processes, tissues, or lesions that exhibit proliferation, i.e., an increase in the number of cells. The term derives from Latin proliferare and is closely related to the concept of proliferation in biological contexts.

In biology and medicine, proliferativas describes activity characterized by rapid cell division or expansion in cell numbers. In pathology, lesions described as proliferativas arise from regenerative or neoplastic growth and are distinguished from non-proliferative degenerative or inflammatory changes. The descriptor is often used to indicate a tendency toward growth or replication within the tissue or lesion.

Common domains where the term appears include ophthalmology (retinopatía proliferativa and proliferative membranes on the retina), dermatology (lesiones cutáneas proliferativas such as certain keratinocytic proliferations and papillomatous growths), and oncology (tumors with high proliferative activity). The proliferative index, assessed by markers like Ki-67 or PCNA, is a tool used to quantify the extent of cellular proliferation in tissue samples.

Usage notes: proliferativas agrees with feminine plural nouns (por ejemplo, lesiones proliferativas). The related singular forms proliferativa or proliferativo are used to modify singular feminine or masculine nouns, respectively. In clinical and histological reporting, the term helps convey that growth through cellular multiplication is a defining feature of the condition being described.
