What is a desmoplastic response?

A desmoplastic reaction is a host response, characterized by a fibrotic connective tissue. It classically occurs due to the presence of malignant cells, and was initially described in breast cancer. Histologically desmoplasia may involve very few cells or an abundance of them.

What is desmoplasia pathology?

Desmoplasia describes a histological pattern characterized by a hyalinized stroma and a minimal cellular infiltrate. In non-cutaneous neoplasms, this pattern of stromal response is classically associated with malignancy, whereas in cutaneous pathology, desmoplasia is observed in malignant as well as benign neoplasms.

Are benign cells anaplastic?

This lack of differentiation, or anaplasia, is often what determines whether a tumor is malignant or benign. Tumors that show increased mitosis, but are still differentiated into the right kind of tissue, are often benign.

What is desmoplastic tumor?

Desmoplastic small round cell tumors, or DSRCT, are tumors that grow in the abdomen and pelvic area of the body. Desmoplastic small round cell tumors are a type of soft tissue sarcoma, which is a type of cancer that forms in the connective tissue of the body.

What is tumor desmoplasia?

In medicine, desmoplasia is the growth of fibrous or connective tissue. It is also called desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, or scar tissue (adhesions) within the abdomen after abdominal surgery.

What is a desmoplastic reaction?

A desmoplastic reaction is a host response, characterized by a fibrotic connective tissue. It classically occurs due to the presence of malignant cells, and was initially described in breast cancer.

What are desmoplastic small round cell tumors?

Desmoplastic small round cell tumors are a type of soft tissue sarcoma, which is a type of cancer that forms in the connective tissue of the body. Connective tissues include fat, muscles, tendons, lymph and blood vessels, and nerves.

What is desmoplasia in dermatology?

Desmoplasia (also known as a desmoplastic reaction) is the term used by pathologists to refer to the growth of fibrous tissue around disease, usually cancer. However in dermatopathology, desmoplasia may also be seen with benign, as well as malignant, conditions.

What is the difference between desmoplasia and oligocellular?

Histologically desmoplasia may involve very few cells or an abundance of them. The oligocellular form comprises a very low number of spindled tumor cells, thinly dispersed (usually as single cells) in a fascicular pattern, separated by bundles of sclerotic collagen, forming an extensive extracellular matrix.
