Is skin rash a common side effect of Lymphoma treatment? How can it be managed?

Skin rash is fairly common with many lymphoma treatments, including chemotherapy, targeted agents, immunotherapy, and radiation, though the exact likelihood depends on the specific drug or modality you receive. Typical rashes can be red, bumpy, dry, and itchy, and they often improve with basic skin care and topical medicines. ^{[1] [2] [3]}

Why rashes happen in lymphoma care

• Chemotherapy effects on fast-growing skin cells: Chemo can irritate and dry the skin because it affects rapidly renewing cells, leading to rashes, itching, and infections. ^{[4] [5]}
• Targeted therapy and antibody drugs: Some agents (e.g., brentuximab vedotin, BTK inhibitors, loncastuximab) can cause cutaneous reactions, including rash and photosensitivity, particularly early in treatment. ^[6] [PM10] [PM9]
• Immunotherapy (checkpoint inhibitors): These can trigger immune-related rashes ranging from mild maculopapular eruptions to more severe dermatitis; most are manageable with skin-directed therapy, and steroids are used for moderate to severe cases. ^{[7] [8] [9]} [PM33] [PM30]
• Radiation therapy to the skin: Radiation can cause localized redness and itching; when skin is treated directly, increased redness and pruritus are common and often respond to topical steroids. ^{[10] [11]}

Common rash patterns you may see

• Dry, itchy, red bumps (maculopapular eruption): Often with chemo and many biologic agents. Moisturizing and gentle skin care are first-line. ^{[1] [2] [3]}
• Photosensitivity (sun-triggered rash): Reported with certain antibody-drug conjugates such as loncastuximab and also during transplant-conditioning regimens; sun protection is key. [PM9] ^[3]
• Immune-related rash (checkpoint inhibitors): Typically appears within weeks; ranges from mild to severe. Topical steroids for mild, add systemic steroids for severe, and pause treatment if very severe. [PM33] [PM31]
• Radiation-related erythema and itch: Often localized to treated areas and managed with gentle topical care and sometimes steroids. ^{[10] [11]}

Practical prevention tips

• Moisturize daily: Use fragrance-free creams or ointments (e.g., sorbolene, aqueous cream) on damp skin after bathing to maintain the barrier. ^{[1] [2]}
• Sun protection: Wear sun-protective clothing, wide-brimmed hats, sunglasses, and apply high-SPF sunscreen (SPF 50 or higher) daily to reduce photosensitive rashes. ^{[1] [2] [3]}
• Gentle cleansing: Choose mild, non-perfumed soaps; avoid harsh scrubs that can worsen irritation. Keeping the skin clean and hydrated helps prevent flare-ups. ^{[4] [12]}
• Avoid scratching: Scratching worsens inflammation and increases infection risk; consider cool compresses or antipruritic lotions. ^{[1] [2]}
• Nail and friction care: Keep nails short and rounded; wear comfortable clothing and footwear to reduce friction and blisters. ^[12]

Step-by-step management when a rash appears

Mild rash (limited area, mild itch)

• Continue treatment unless your care team advises otherwise. [PM33]
• Topical therapy: Apply mid-potency topical corticosteroids (e.g., triamcinolone) to inflamed areas and use regular emollients to the whole body. Add oral antihistamines if itch interferes with sleep. [PM33] ^[4]
• Sun protection and gentle care: Maintain strict photoprotection and avoid irritants. ^{[3] [12]}

Moderate rash (more widespread or bothersome)

• Inform your oncology team promptly to guide adjustments. They may temporarily hold a dose depending on the agent and severity. ^[8] [PM33]
• Topical steroids plus short course oral steroids: For checkpoint-inhibitor rashes, clinicians often add oral corticosteroids if topical therapy is not enough. [PM33] [PM31]
• Antibiotics for certain targeted-therapy rashes: Some acneiform or follicular rashes (more common with EGFR inhibitors, but similar principles can apply) respond to topical or oral antibiotics due to anti-inflammatory effects. [PM20] [PM21] [PM22]

Severe rash (blistering, extensive skin detachment, fever)

• Stop the implicated therapy and seek urgent care immediately. This may indicate severe immune-related dermatitis or rare syndromes (e.g., Stevens–Johnson). [PM31] [PM33]
• Hospital-based management: Systemic corticosteroids and specialist dermatology input are standard; additional immunosuppressive agents may be used if steroid-refractory. [PM30] [PM33]

Drug-specific notes

• Brentuximab vedotin: Red, bumpy, itchy rash can occur; moisturizers, sun protection, and clinician-guided therapies help; tell your team about new or worsening rashes. ^[6]
• BTK inhibitors (ibrutinib, acalabrutinib, zanubrutinib): Rashes can occur and may be milder with newer agents; ongoing monitoring and supportive care improve tolerability. [PM10]
• Loncastuximab tesirine: Rash/photosensitivity is common early; management includes dose delay/discontinuation if needed and steroids/antihistamines, with strong sun protection. [PM9]
• Checkpoint inhibitors (e.g., nivolumab): Immune-mediated rashes sometimes require systemic steroids; therapy may be paused, and rash typically resolves, though recurrence can happen upon rechallenge. ^{[8] [9]}
• Radiation for lymphoma: Skin-directed radiation often causes redness and itch where treated; topical steroids frequently help. ^{[10] [11]}

When to contact your care team

• New rash that spreads quickly, blisters, or is painful. These could signal a serious reaction that needs urgent assessment. [PM33]
• Rash with fever or feeling unwell. Systemic symptoms raise concern for severe immune-related events. [PM31]
• Any rash that interferes with sleep or daily activities despite basic care. Early intervention helps avoid treatment interruptions. ^[4] [PM30]

Everyday skin-care checklist

• Apply fragrance-free moisturizer twice daily, especially after bathing. ^{[1] [2]}
• Use SPF 50 sunscreen, reapply every 2–3 hours outdoors; wear protective clothing and hats. ^{[1] [3]}
• Cleanse with mild, non-perfumed soap; avoid hot water and harsh exfoliants. ^{[4] [12]}
• Avoid scratching; consider cool compresses and antihistamines at night for itch. ^{[1] [4]}
• Keep nails short and avoid friction; choose loose, breathable clothing. ^[12]

Key takeaways

• Yes skin rashes are common across several lymphoma treatments, often presenting as red, bumpy, dry, and itchy skin. Basic skin care, moisturizers, sun protection, and topical steroids usually help, and your team may add antihistamines or short courses of oral steroids when needed. ^{[1] [2] [4]}
• Immune therapy rashes may need graded management, from topical treatments to systemic steroids and temporary drug holds in more severe cases. [PM33] ^[8]
• Photosensitivity is a frequent pattern with some agents, so daily high-SPF protection and covering up are important. [PM9] ^[3]
• Serious symptoms (blistering, fever) require urgent evaluation and stopping the causative drug until assessed. [PM31] [PM30]
