Turban Tumor (Cylindroma)

What is Turban Tumor (Cylindroma)?

A turban tumor is a type of cutaneous adnexal neoplasm more formally called a cylindroma. The name “turban” comes from the way multiple lesions can coalesce on the scalp, creating a thick, hair‑bearing mass that resembles a turban. Cylindromas are benign (non‑cancerous) tumors that arise from the eccrine (sweat‑gland) or apocrine lineage of the skin.

While most cylindromas are isolated, they can appear in clusters, especially in individuals with an inherited syndrome called familial cylindromatosisBrooke‑Spiegler syndrome. In those cases, dozens to hundreds of lesions may develop over a lifetime, most often on the scalp, face, neck, and occasionally on the trunk. Although the tumors are usually harmless, they can be disfiguring, bleed, become infected, or very rarely undergo malignant transformation into a cylindro‑carcinoma.

Common Causes

Turban tumors are not caused by lifestyle factors; instead they arise from genetic or molecular abnormalities. The most common causes are:

• Mutations in the CYLD gene – loss‑of‑function variants on chromosome 16q12‑13 are the hallmark of familial cylindromatosis.
• Brooke‑Spiegler syndrome – an autosomal‑dominant condition caused by CYLD mutations that produces cylindromas, spiradenomas, and trichoepitheliomas.
• Familial cylindromatosis – another name for the same CYLD‑related disorder, often confined mainly to the scalp.
• Spontaneous (sporadic) CYLD mutations – isolated cylindromas can arise without a family history.
• Radiation exposure – rare case reports suggest that therapeutic or occupational radiation may trigger tumor formation in predisposed individuals.
• Chronic sun damage – UV injury can act as a co‑factor, especially on sun‑exposed scalp skin.
• Immunosuppression – organ‑transplant recipients and patients on long‑term immunosuppressants have a slightly higher risk of developing adnexal tumors.
• Other genetic syndromes – rare overlaps with conditions such as multiple endocrine neoplasia type 1 (MEN‑1) have been described.
• Trauma or chronic irritation – persistent friction on the scalp (tight headgear) may promote coalescence of existing lesions.

Associated Symptoms

Most cylindromas are painless and asymptomatic, but the following features are frequently reported:

• Soft, firm, or rubbery nodules that range from a few millimeters to several centimeters.
• Lesions are usually pink, red, or flesh‑colored; over time they may become bluish or brownish.
• Hair growth persists through the tumor, giving the scalp a “bushy” appearance.
• Itching or mild tenderness, especially if the lesion rubs against clothing or a hat.
• Bleeding or ulceration after trauma or when the tumor is scraped.
• Secondary infection (redness, warmth, purulent discharge) if the surface breaks.
• Cosmetic concern or psychological distress due to visible scalp “mass.”
• Very rarely, rapid growth, ulceration, or a painful nodule may signal malignant change.

When to See a Doctor

Consult a dermatologist or primary‑care physician promptly if you notice any of the following:

• New nodules on the scalp, face, or neck that continue to enlarge over weeks‑months.
• Rapid change in size, color, or shape of an existing lesion.
• Persistent pain, itching, or bleeding that does not resolve with basic wound care.
• Signs of infection (redness, warmth, pus, fever).
• Family history of cylindromas, Brooke‑Spiegler syndrome, or other skin adnexal tumors.
• Any lesion that begins to ulcerate or develop a foul odor.

Diagnosis

Diagnosing a turban tumor usually follows a stepwise approach:

Clinical Evaluation

• Thorough skin exam focusing on the scalp, face, neck, and any other affected sites.
• Documentation of lesion number, size, distribution, and any changes over time.
• Family history and review of systemic symptoms.

Biopsy

A punch or excisional biopsy is the gold standard. Histology shows nests of basaloid cells surrounded by thick hyaline basement‑membrane material, creating the classic “jigsaw puzzle” pattern. Immunohistochemistry (e.g., positive for cytokeratin 5/6, p63) helps confirm the diagnosis.

Genetic Testing

If multiple cylindromas are present or there is a suggestive family history, testing for CYLD gene mutations is recommended. Results guide counseling, surveillance, and family‑member screening.

Imaging (rarely needed)

• Ultrasound or MRI may be ordered if a deep lesion is suspected or to evaluate involvement of underlying bone.
• CT scans are used only when there is suspicion of malignant transformation extending beyond the skin.

Treatment Options

Therapy is individualized based on tumor size, number, location, patient age, and cosmetic considerations.

Medical (Non‑Surgical) Approaches

• Topical or intralesional therapies – limited data, but topical imiquimod or intralesional corticosteroids have been used for small, symptomatic lesions.
• Laser ablation – CO₂ or Nd:YAG lasers can vaporize superficial tumors with good cosmetic outcomes.
• Electrodesiccation & curettage (EDC) – effective for isolated nodules; repeated sessions may be needed.
• Targeted molecular therapy – early‑phase trials are exploring inhibitors of the NF‑κB pathway, which is overactive in CYLD‑mutated cells. Not yet standard of care.

Surgical Treatments

• Excisional surgery – complete removal with clear margins is curative for solitary lesions.
• Mohs micrographic surgery – preferred for cosmetically sensitive areas (face, scalp) because it spares healthy tissue while ensuring tumor clearance.
• Scalp reconstruction – for large “turban” masses, skin grafts or rotational flaps may be required after tumor removal.

Management of Multiple Tumors

When dozens of tumors are present, a staged approach is common:

• Prioritize removal of the largest, symptomatic, or potentially malignant nodules.
• Combine laser, EDC, and limited excisions to reduce tumor burden while preserving scalp integrity.
• Regular follow‑up (every 6–12 months) for early detection of new lesions.

Supportive & Home Care

• Gentle cleansing with mild, fragrance‑free soap; avoid scrubbing the lesions.
• Apply petroleum‑jelly or a non‑stick dressing if a tumor ulcerates to keep it moist and prevent crusting.
• Use loose‑fitting hats or headbands; avoid tight hair accessories that may cause friction.
• Promptly treat any secondary infection with topical antibiotics (e.g., mupirocin) or oral agents as prescribed.

Prevention Tips

Because most turban tumors are genetically driven, primary prevention is limited, but patients can adopt measures that reduce secondary complications and possibly slow new tumor formation:

• Sun protection – wear a wide‑brimmed hat, use SPF 30+ sunscreen on exposed scalp, and avoid peak UV hours.
• Regular skin checks – self‑examination monthly and professional dermatologic exams annually (or more often if you have a known CYLD mutation).
• Avoid chronic irritation – keep headgear loose, limit excessive hair styling heat.
• Maintain good scalp hygiene – keep hair clean but avoid harsh chemicals.
• Quit smoking – tobacco can impair wound healing after tumor removal.
• Genetic counseling – families with CYLD mutations benefit from counseling to understand inheritance patterns and testing options.

Emergency Warning Signs

Key Take‑aways

• Turban tumors (cylindromas) are benign skin adnexal neoplasms often linked to CYLD gene mutations.
• They most commonly appear on the scalp, forming a “turban”‑like mass when many lesions coalesce.
• Most are painless, but they can bleed, become infected, or very rarely turn cancerous.
• Diagnosis relies on clinical exam and biopsy; genetic testing is advisable for multiple or familial cases.
• Treatment ranges from surgical excision and Mohs surgery to laser or electrodessication, with a tailored approach for patients with many lesions.
• Regular monitoring, sun protection, and early specialist referral are essential to manage existing tumors and catch any malignant change promptly.
