Syringomas

Syringomas are benign tumours of the eccrine sweat ducts — not milia, not sebaceous, and not treatable by extraction.

Syringomas — assessed at IN Eternity Clinic Singapore
In short

Syringomas are small, benign growths of the sweat ducts, usually clustered on the lower eyelids and upper cheeks. They look like milia but are solid, so there is nothing to squeeze out. Treatment, most often pinpoint CO2 laser, aims to make them less visible rather than clear them for good, and new ones can appear. See syringoma removal in Singapore.

Key facts
  • What they are: benign growths of the eccrine sweat duct, sitting in the upper dermis.
  • Where they appear: most often the lower eyelids and upper cheeks, usually on both sides; sometimes the neck, chest or genital skin.
  • Key clue: skin-coloured or slightly yellow, flat-topped bumps of 1–3 mm in clusters. Milia are white, round and can be emptied; syringomas cannot.
  • Who gets them: more common in women and in Asian skin, often appearing from the teenage years onwards; some families have several affected members.
  • What treatment aims for: less visible bumps, not clearance. Because the duct sits in the dermis, removing the surface alone leaves the source behind.
  • Recurrence: common. Treated syringomas can partly return and new ones can form, so touch-ups are part of the plan.
  • Assessed by: Medical Director Dr Sin Yong at IN Eternity Clinic, 9 Scotts Road, Singapore.

Mechanism

What is actually happening

Small skin-coloured to slightly yellow papules, typically 1 to 3 mm, clustering symmetrically under the eyes and on the upper cheeks, arising from the intraepidermal portion of the eccrine duct.

The distinction

How it is told apart

The commonest misdiagnosis is milia. Milia are white and discrete; syringomas are skin-coloured, flatter, and cluster in sheets. Milia can be de-roofed and emptied. Syringomas cannot — there is nothing inside to express.

Assessment

What is established first

Distribution and symmetry, colour against surrounding skin, onset age, family history, and whether the pattern is eruptive.

Approach

What is typically done

Because the lesions sit within the dermis and are numerous, management focuses on reducing prominence rather than clearing them entirely. Ablative approaches are used cautiously around the eyelid, where skin is thin.

When treatment waits

When it is deferred

Syringomas are persistent and recurrence after treatment is common. Anyone promising permanent clearance is overstating what the tissue allows.

In practice

How syringomas are treated at IN Eternity

The first step is to confirm that the bumps are syringomas and not milia, sebaceous hyperplasia or flat warts, which look similar under the eyes but are treated differently. Under magnification syringomas are firm, flat-topped and have no central opening.

The usual method is pinpoint CO2 laser on the DEKA Tetra Pro platform, which vaporises each bump in fine, controlled passes, sometimes with fine electrocautery for very small lesions. A systematic review of syringoma treatment found that destructive methods such as laser and electrosurgery were the most reported, and that recurrence and pigment change were the main drawbacks. Around the eyes, depth is kept conservative and the eye is protected throughout.

What to expect

Syringoma treatment: recovery and number of sessions

Each treated bump forms a small crust that lifts within about a week; the skin underneath is pink for a few weeks and needs strict sun protection, because darkening after treatment is a real risk in Asian skin. Larger clusters are usually treated in stages, a few weeks apart, rather than all at once.

Most people see the bumps become flatter and less noticeable after one to three sessions. Some remain or return, and the plan includes reviewing and touching them up rather than chasing complete clearance in one go.

“Syringomas are solid, so there is nothing to squeeze. An offer to extract them is a sign they have been mistaken for milia.”

Frequently asked

What are syringomas?

Syringomas are benign tumours of the eccrine sweat ducts — not milia, not sebaceous, and not treatable by extraction.

How are syringomas told apart from similar conditions?

The commonest misdiagnosis is milia. Milia are white and discrete; syringomas are skin-coloured, flatter, and cluster in sheets. Milia can be de-roofed and emptied. Syringomas cannot — there is nothing inside to express.

What is assessed before treating syringomas?

Distribution and symmetry, colour against surrounding skin, onset age, family history, and whether the pattern is eruptive.

When is treatment deferred?

Syringomas are persistent and recurrence after treatment is common. Anyone promising permanent clearance is overstating what the tissue allows.

Can syringomas be removed permanently?

No method reliably removes them for good. Laser and electrocautery can make them much less visible, but because the sweat duct sits deep in the skin, some can return and new ones can appear over the years.

Is it safe to laser syringomas under the eyes?

Yes, when done with fine, conservative settings and eye protection by a doctor who treats this area routinely. The lower eyelid skin is thin, which is why depth is kept modest and larger clusters are treated in stages.
