A histiocytoma originates from histiocytes. The most common type of histiocytoma is a malignant fibrous histiocytoma (MFH), which account for up to 24 percent of all soft tissue sarcomas. MFHs are classified into five subtypes by histology: angiomatoid, giant cell, inflammatory, myxoid and storiform. The prognosis of a histiocytoma is determined primarily by the tumor's grade, size and degree of metastasis. The following steps will show how to treat a histiocytoma.
Treat most histiocytomas surgically. The aggressive nature of these tumors usually requires prompt action to completely remove it. The preferred technique is a radical or wide resection and followed by close monitoring with Magnetic Resonance Imaging to check for recurrence.
Consult with the orthopedic surgeon before performing a biopsy on a suspected histiocytoma. The biopsy tract may need to be removed along with the mass in some cases, and an orthopedic consultation can minimize the extent of the surgery.
Verify that a dermatofibroma is benign. This type of histiocytoma on the skin rarely requires treatment after it has been definitively identified. The patient should report any changes to a physician as with any skin lesion.
Use complete excision, including the subcutaneous fat on dermatofibromas that have not been diagnosed, are cosmetically unacceptable or are particularly symptomatic. A biopsy shaped like an inverted pyramid can be cosmetically desirable and still provide enough tissue for a histological analysis.
Treat dermatofibromas with shaving or cryosurgery for cosmetic reasons. However, the chance of recurrence is more likely with these procedures.
