Fibrosarcoma : Clinical Features
Image Description
Clinical Presentation: Adult-type fibrosarcoma usually presents as a solitary, painless, slow-growing, palpable mass, measuring 5-10 cm in size. The overlying skin is usually intact. Ulceration may occur if the tumor is located superficially or experiences rapid growth. If neglected, it may develop into a large fungating, ulcerated mass as seen in this image.
Most patients are between 30 and 50 years of age (range 5 to 75 years; median age 50 years). Fibrosarcoma can occur virtually at any location. The most common sites are deep soft tissues of the extremities (lower > upper), trunk, and head and neck region. It arises from intramuscular and intermuscular fibrous tissue, aponeuroses, tendons, and fascial coverings. The tumor may surround the bone and cause periosteal reaction, mimicking parosteal osteosarcoma.
Rare fibrosarcomas arise in the subcutis from dermatofibrosarcoma protuberans or in tissues damaged by radiation, heat, and scars.
