ICD-10: C49.1

The ICD-10 code C49.1 refers to a specific diagnosis of a malignant neoplasm (cancer) affecting the connective and soft tissues of the upper limb, including the shoulder. This classification is part of the broader category of soft tissue sarcomas, which are tumors that arise from the connective tissues of the body, such as fat, muscle, nerves, fibrous tissues, blood vessels, and lymphatic tissues.

Clinical Description

Definition

C49.1 is designated for malignant tumors that originate in the soft tissues of the upper limb, which encompasses the arm, forearm, hand, and shoulder region. These tumors can vary significantly in their histological types, aggressiveness, and clinical behavior.

Types of Tumors

Soft tissue sarcomas can be classified into various subtypes, including but not limited to:
- Liposarcoma: A malignant tumor of adipose (fat) tissue.
- Fibrosarcoma: A tumor arising from fibrous connective tissue.
- Rhabdomyosarcoma: A malignant tumor of skeletal muscle.
- Synovial sarcoma: A tumor that typically occurs near joints and tendons.

Symptoms

Patients with C49.1 may present with a range of symptoms, including:
- A noticeable lump or mass in the upper limb.
- Pain or discomfort in the affected area.
- Swelling or changes in the skin over the tumor.
- Limited range of motion in the shoulder or arm.

Diagnosis

Diagnosis typically involves a combination of imaging studies (such as MRI or CT scans) and a biopsy to confirm the presence of malignant cells. The histological examination will help determine the specific type of sarcoma, which is crucial for treatment planning.

Treatment Options

Surgical Intervention

Surgery is often the primary treatment for soft tissue sarcomas, aiming to remove the tumor along with a margin of healthy tissue to minimize the risk of recurrence.

Radiation Therapy

Radiation therapy may be used either as an adjunct to surgery (to reduce the risk of local recurrence) or as a primary treatment in cases where surgery is not feasible.
