Lipoma and skin cyst

Epidermoid cystLipoma beneath the skin
Lipoma and skin cyst · anatomical diagramA lipoma lies in the fatty tissue beneath the skin; an epidermoid cyst is a well-defined cyst in or under the skin.Simplified illustration of the condition; not an individual medical finding.

Lipomas and skin cysts are common causes of benign lumps beneath the skin, but differ in structure. A lipoma consists of fatty tissue. The German term “Atherom” commonly refers to certain skin cysts filled with skin material. Not every lump is one of these. Examination therefore comes before removal. Benign, unremarkable findings do not always need treatment; growth, pain or inflammation may change that decision.

When to seek medical help

A rapidly growing, deep or poorly mobile lump should be assessed promptly. Redness with fever or spreading inflammation requires urgent examination.

Causes and risk factors

The cause of a lipoma is often unclear; it sometimes runs in families. Skin cysts develop from skin or hair-follicle structures. They are not a sign of general poisoning and cannot reliably be prevented through detox regimens. A recurrent lump after previous treatment is assessed again. Larger or deep changes need more detailed assessment before apparently simple removal is planned.

Typical symptoms

Lipomas are often soft, slow-growing and somewhat mobile. Skin cysts tend to feel round and smooth; a small pore may be visible. Either may be troublesome because of pressure or location. An inflamed cyst becomes painful, red and warm and may discharge fluid. Rapid growth, fixation to deeper tissue or an unusual appearance needs assessment. Absence of pain alone does not prove a lump is harmless.

Diagnosis

We assess size, depth, consistency, skin changes and progression. Ultrasound may clarify location and structure in selected cases. Deep, large, fast-growing or otherwise unusual lumps may need further imaging or specialist assessment before surgery. Removed tissue is examined microscopically according to the findings. Assessment helps avoid unnecessary procedures and direct suspicious changes to appropriate care.

Non-surgical treatment

A confidently diagnosed, symptom-free lump can often be observed. Medicines do not reliably make a lipoma disappear. Inflamed cysts need treatment of infection according to severity; an abscess may need drainage. Squeezing or puncturing them yourself is unhelpful and can worsen inflammation and scarring. Definitive removal may be postponed until severely inflamed tissue has settled. Progress and warning signs are discussed.

Surgical options

Removal may be appropriate for symptoms, growth or another suitable indication. The cyst capsule matters for recurrence risk; lipoma location and how clearly it is defined are considered. Selected skin and soft-tissue procedures, including lipoma and skin-cyst removal, are part of our outpatient service at the external surgical centre. Anaesthesia and extent depend on the findings. Scarring, bleeding, infection, sensory changes and possible recurrence are discussed during individual consent.

Aftercare and rehabilitation

Wound checks and removal of stitches where necessary follow excision. Movement and loading depend on location and wound tension. Histology results are discussed if testing was arranged. A small skin wound does not mean heavy lifting or forceful stretching is immediately appropriate. Increasing redness, warmth, discharge and pain should be checked. Any later new lump is examined again.

Common questions

Is every soft lump a lipoma?

No. Examination establishes whether it appears to be a lipoma or needs further investigation.

Can I squeeze a skin cyst?

This is not recommended. The capsule often remains, and pressure can worsen inflammation and scarring.

Will removal leave a scar?

Yes. A skin incision leaves a scar. Its size and appearance depend on location, findings and healing.

Arrange a consultation

We discuss which treatment is suitable for your findings and which procedures are available within our outpatient service during a personal consultation. Outpatient operations take place at an external surgical centre.
