R22.33

Clinical Causes: Inflammatory conditions such as tendinitis or bursitis Infections leading to abscess formation or cellulitis Benign tumors like lipomas or cysts Malignant tumors including sarcomas or metastases Lymphatic or vascular obstructions causing swelling Trauma or injury resulting in hematoma or swelling Allergic reactions causing localized swelling Swelling due to systemic conditions such as edema related to heart, kidney, or liver problems

Key Symptoms: Noticeable lumps or masses on one or both upper limbs Localized swelling around the affected area Possible pain or tenderness in the area of swelling Changes in skin color or texture over the lump Limited movement or stiffness if swelling affects joints or muscles In some cases, redness or warmth indicating inflammation or infection Possible systemic symptoms such as fever if infection is present

Diagnosis Path: Medical history review, including duration and any associated symptoms Physical examination to assess the size, consistency, mobility, and tenderness of lumps Imaging studies such as ultrasound to evaluate the nature of the mass MRI or CT scans for detailed visualization if necessary Laboratory tests including blood work to identify infections or systemic causes Biopsy or fine needle aspiration if malignancy is suspected

Treatment Protocols: Observation and monitoring if the lump is benign and not causing symptoms Medications such as anti-inflammatory drugs for swelling and pain Antibiotics if an infection is diagnosed Surgical removal of benign masses or malignant tumors Drainage procedures for abscesses or cystic growths Addressing underlying systemic conditions that contribute to swelling, such as heart or kidney disease Physical therapy to restore movement if affected by swelling or mass
