A skin cyst is a closed, benign sac beneath the skin filled with keratin, sebum or fluid depending on the cyst type. The most common types — epidermoid cysts (from surface skin cells), sebaceous cysts (from sebaceous glands) and pilar cysts (from hair follicles, usually on the scalp) — are almost always benign and not dangerous. They do not transform into cancer in the vast majority of cases. However, a small subset of pilar cysts can undergo malignant change (proliferating trichilemmal cysts), which is one reason histological analysis of every excised cyst is clinically important. Any lump that grows rapidly, is hard or fixed, is associated with overlying skin changes, or is clinically atypical should be assessed and excised for histological confirmation promptly — do not assume any lump is definitively benign without a pathology report.

No — skin cysts do not resolve spontaneously. Once formed, a cyst persists and most grow progressively larger over months to years. No cream, supplement, home remedy or topical treatment eliminates an established skin cyst. The only method that permanently removes a cyst is surgical excision of the entire cyst and its sac. Needle aspiration (draining the cyst with a needle) and incision and drainage (for infected cysts) are temporary measures that reduce the cyst's size or drain its contents but leave the sac in place — meaning the cyst almost always recurs, often returning larger and more adherent than before. If you have a cyst that you want permanently gone, surgical excision is the only reliable answer. Monitoring a small, stable, non-symptomatic cyst is reasonable — but it is a deferral strategy, not a resolution.

The procedure is performed under local anaesthesia as a day-surgery outpatient procedure. The skin is cleaned with antiseptic. A small elliptical incision is made over the cyst — including the punctum (the small skin pore over the cyst, where present) — to allow removal of the entire cyst sac without leaving residual sac cells that could regenerate the cyst. The cyst is carefully dissected free from the surrounding tissue along the natural plane of its outer wall, ideally removed intact without rupturing the sac. The wound is irrigated, closed in layers with fine sutures, and covered with a waterproof dressing. The excised cyst is sent for histological analysis. The whole procedure typically takes 20–40 minutes for a single cyst. You feel pressure during the dissection but no sharp pain — the local anaesthesia is very effective.

During the procedure, there is no pain — local anaesthesia numbs the area completely before any incision is made. The anaesthetic injection causes a brief sting for a few seconds; after that, the area is fully numb and the excision is pain-free. Most patients are surprised by how little they feel beyond gentle pressure and movement during the procedure. After surgery, as the anaesthesia wears off (2–4 hours post-procedure), mild soreness and tenderness develop at the wound site. This is well managed with paracetamol or mild over-the-counter pain relief and typically resolves substantially within 3–5 days. Cyst excision is consistently described by patients as producing much less post-operative discomfort than they anticipated — it is one of the most straightforward minor surgical procedures performed by a cosmetic surgeon.

Recurrence after complete surgical excision — where the entire cyst sac is removed intact — is uncommon, estimated at below 3–5%. The key is completeness: any sac remnant left in the wound can regenerate the cyst. This is why complete intact sac excision is the explicit surgical goal at Maynee — not simply removing the cyst contents or leaving a small fragment of sac "because it was adherent." Cysts that have been previously drained, aspirated or infected are often more adherent and technically more challenging to remove without partial rupture — which is one reason complete elective excision of an uninfected cyst is preferable to repeated drainage followed by a more difficult excision later. If a cyst does recur after excision at another clinic, definitive re-excision at Maynee is the appropriate next step.

Not as an immediate elective excision — but the situation needs to be managed promptly in stages. An actively infected or inflamed cyst requires immediate treatment first. If the cyst is cellulitic (red, swollen and tender but not yet a formed abscess), a course of antibiotics is prescribed to reduce the infection. If an abscess has formed (fluctuant collection of pus causing significant pain), incision and drainage (I&D) under local anaesthesia is performed to drain the pus and relieve pain immediately. Neither antibiotics nor I&D removes the cyst sac — so the cyst will almost certainly recur. Definitive complete excision of the residual cyst sac is then planned after the infection and inflammation have fully resolved, typically 4–6 weeks later. Attempting complete excision of an actively infected cyst carries higher wound complication risks and — critically — makes it almost impossible to identify and remove the complete cyst sac cleanly, significantly increasing recurrence risk. At Maynee, we manage infected cysts promptly and plan definitive excision at the right time.

Any surgical incision heals with a scar — this cannot be avoided. The question is whether the scar is noticeable — and the honest answer is that well-placed, properly closed cyst excision scars are almost always significantly less noticeable than the cyst they replace. At Maynee, every incision is planned to be as small as technically possible for the cyst's size and depth, placed in natural skin creases, Langer's lines or hair-bearing areas wherever anatomically available, and closed with fine, layered suturing technique to produce the narrowest, flattest possible scar. Scalp pilar cyst scars are hidden entirely within the hair. Neck and face cyst scars placed within natural creases become effectively invisible at 3–6 months maturity. Patients with a personal or family history of keloid or hypertrophic scarring should disclose this at consultation so the approach can be modified accordingly.

Recovery from cyst excision is typically rapid. Most patients return to desk work and light daily activities the day following surgery. Sutures are removed at 7–10 days. Strenuous exercise, heavy lifting, swimming and activities that significantly raise the heart rate should be avoided for 2 weeks to allow the wound to heal properly. Normal showering with a waterproof dressing in place can resume after 48 hours. Any swelling, bruising or tenderness at the wound site resolves within 1–2 weeks. The scar continues to mature, soften and fade over 3–6 months. Most patients find the recovery from cyst excision significantly easier and faster than they anticipated — it is one of the most straightforward outpatient surgical procedures with minimal real-world disruption to daily life.

This distinction is widely misunderstood. What most patients — and many doctors — call a "sebaceous cyst" is almost always an epidermoid cyst (epidermal inclusion cyst). True sebaceous cysts originating directly from sebaceous glands are actually quite rare. Epidermoid cysts form when epidermal (surface skin) cells are displaced into the dermis and create a sac filled with keratin — a white, cheesy material with a characteristic odour when disrupted. True sebaceous cysts form from sebaceous glands and contain sebum. Both present as smooth, round, movable lumps. The distinction can only be definitively made on histological analysis of the excised specimen — which is precisely why histology is performed on every cyst excised at Maynee. From a practical surgical perspective, the excision technique for both types is essentially the same: complete sac removal with intact excision. The clinical distinction matters primarily for the histology report and permanent medical record.

Cyst removal cost at Maynee in Chennai depends on the type, size and location of the cyst, the number of cysts to be removed, whether the cyst has been previously infected or drained (which affects surgical complexity), whether imaging (ultrasound) is required before surgery, and the histological analysis — which is included as standard for every cyst excised at Maynee. Because every cyst is different and every procedure is personalised after thorough clinical assessment, we do not publish fixed pre-set prices. A complete, transparent cost breakdown with no hidden charges is provided at your consultation after the surgeon has examined the cyst and confirmed the surgical plan. You leave with full clarity on the procedure and cost — with no obligation to proceed. There are no surprise fees.
