"Signal characteristics"
"Desmoplastic fibroblastomas are rare and usually occur in the adult population with a median age of 50-60 years. There is no known gender predilection 1."
"Desmoplastic fibroblastomas usually occur in the subcutaneous tissues but the involvement of skeletal muscle and fascia is common. The extremities and limb-girdle areas are most commonly involved such as the shoulder, upper arm, lower limb, the back, the forearm or the hand and feet. There are also cases occurring in the head and neck region 1-4."
"Desmoplastic fibroblastomas are benign tumours. There are no reports of recurrences after surgical excision 1."
"Desmoplastic fibroblastomas have been described as well-defined soft tissue masses often adjacent to dense connective tissues and associated with muscle, deep muscular fascia, joints and tendons 2-5."
