Benign fibrous histiocytoma

Benign fibrous histiocytoma (BFH) is a type of tumor that originates from fibroblast cells, which are responsible for producing collagen and other types of connective tissue. Despite its name, BFH is not related to histiocytes, a type of immune cell.

Overview

BFH is a common type of soft tissue tumor, often found in the dermis layer of the skin. It is typically benign, meaning it does not spread to other parts of the body. However, it can recur locally if not completely removed.

Symptoms and Diagnosis

BFH often presents as a painless, firm nodule on the skin. It can occur anywhere on the body, but is most commonly found on the lower legs. The size of the tumor can vary, but it is typically less than 2 cm in diameter.

Diagnosis of BFH is typically made through a biopsy, where a small sample of the tumor is removed and examined under a microscope. The tumor cells in BFH are characterized by their spindle shape and arrangement in a storiform (cartwheel) pattern.

Treatment and Prognosis

The primary treatment for BFH is surgical removal of the tumor. This is typically done through excision surgery, where the entire tumor and a small margin of healthy tissue around it are removed to ensure complete removal of the tumor.

The prognosis for BFH is generally good, as it is a benign tumor. However, there is a risk of local recurrence if the tumor is not completely removed. Regular follow-up appointments are recommended to monitor for any signs of recurrence.
