Hello dear cat lovers! Dr Duncan Houston BVSc here, your friendly vet, bringing trusted, compassionate insight into a common yet often misunderstood skin issue—the cystic hair follicle tumor in cats. Let's dive into this topic with warmth, clarity, and actionable advice you can rely on in 2025 and beyond. 😊

🔍 What Are Cystic Hair Follicle Tumors?

Cystic hair follicle tumors are growths arising from the structures that hold your cat’s hair. They often begin as small, firm cysts filled with keratin or fluid—sometimes called keratinized cysts or follicular cysts :contentReference[oaicite:1]{index=1}.

In veterinary dermatology, these tumors include:

• Trichoepitheliomas: Benign, representing multiple layers of the hair follicle :contentReference[oaicite:2]{index=2}.
• Pilomatricomas: Originating from the hair matrix, possible but rare in cats :contentReference[oaicite:3]{index=3}.
• Trichilemmal cysts: Also called pilar cysts, with a keratin core :contentReference[oaicite:4]{index=4}.

🐈 Who Gets Them & Why?

• Middle‑aged to older cats are more susceptible :contentReference[oaicite:5]{index=5}.
• Specific breeds, like Siamese, may be predisposed :contentReference[oaicite:6]{index=6}.
• Causes include genetic factors, blocked follicles, inflammation, or sun damage in hairless/white areas :contentReference[oaicite:7]{index=7}.

🔬 Signs & Symptoms

These tumors commonly appear as:

• Firm, round nodules (1–5 cm), deeper under the skin :contentReference[oaicite:8]{index=8}.
• Local ulceration or discharge if traumatized :contentReference[oaicite:9]{index=9}.
• Usually a single lump, but multiple can occur :contentReference[oaicite:10]{index=10}.

🩺 When to See the Vet

Bring your cat in if you notice:

• A new lump or bump.
• The lump is changing rapidly, ulcerated, or painful.
• Multiple lumps appear over time.

Early evaluation is key—cytology or biopsy confirms whether it's benign or malignant :contentReference[oaicite:11]{index=11}.

🧪 Diagnosis Process

Your veterinarian will likely perform:

• Fine‑needle aspiration (FNA) for cell sample :contentReference[oaicite:12]{index=12}.
• Tissue biopsy for histopathology (especially if FNA is unclear) :contentReference[oaicite:13]{index=13}.
• Additional scans (ultrasound, X‑rays) if malignant features are found :contentReference[oaicite:14]{index=14}.

💉 Treatment Options in 2025

🔹 Surgical Excision

The top treatment is complete surgical removal, ideally with clear margins. This cures benign tumors and limits malignant ones :contentReference[oaicite:15]{index=15}.

🔹 Laser or Cryotherapy

Smaller, superficial tumors can be treated with minimally invasive methods—quicker healing, less invasive care :contentReference[oaicite:16]{index=16}.

🔹 Additional Oncology Care

If malignancy is found, options include:

• Wide excision plus radiation — especially if margins are uncertain.
• Chemotherapy for rare aggressive cases.
• Follow‑up every 3 months in year one, then 6‑monthly in year two, and annually after that :contentReference[oaicite:17]{index=17}.

💚 Post-Treatment Care & Monitoring

• Use an Elizabethan collar to prevent licking.
• Manage wound healing with brand-recommended products from Woopf & Purrz.
• Check regularly for new lumps—each may need separate evaluation.
• Keep up annual check-ups via Ask A Vet app 📱.

📝 Prognosis

• Most benign hair follicle tumors have an excellent prognosis post-removal :contentReference[oaicite:18]{index=18}.
• Malignant forms are rare; with early removal and imaging, long-term outcomes are still favorable :contentReference[oaicite:19]{index=19}.

🧩 Key Takeaways

• Not all lumps are cancer. But always vet-check growths.
• Early diagnosis saves lives. FNA and biopsies clarify next steps.
• Surgery is effective. Laser, cryo, or oncology options support recovery.
• Ongoing monitoring matters. Tumors can recur or appear elsewhere.
