Aim of Case Study

To conduct a study using Advanced Electrolysis to remove Dermatosis Papulosa Nigra effectively leaving little/no scar to the skin

what is dermatosis papulosa nigra

What is Dermatosis Papulosa Nigra?

Dome shaped- brown/black papules

Benign lesions

Usually found on upper body/face cheeks, neck

Measure 1mm-5mm in diameter

Crusting, ulceration, flaking do not occur

Cosmetically unattractive

Do not disappear without treatment

what causes dermatosis papulosa nigra

What causes Dermatosis Papulosa Nigra?

Exact cause is unknown

Variation of seborrhoeic keratosis

Genetically determined- 40-50% chance of developing if there is a family history

Possible pilosebaceous follicle that does not develop properly

who gets dermatosis papulosa nigra

Who gets Dermatosis Papulosa Nigra

Affects all black skin types e.g. 35% African American

Affects Asian/Polynesian skin types- frequency unknown

More common in females

Begins in adolescence- number and size increase with age

existing treatments for dermatosis papulosa nigra

Existing Treatments for Dermatosis Papulosa Nigra

Surgery

Cryotherapy- Liquid Nitrogen

Laser e.g. CO2, Nd YAG

Trichloroacetic acid

Natural Remedies e.g. homeopathy

Camouflage Make Up

Advanced Electrolysis

history of electrolysis

History of Electrolysis

Invented by Dr Charles E Michel 1875

Developed for Trichiasis

Uses galvanic/short wave diathermy current

Insertion of needle- emitting current

FDA approved for permanent hair removal

advanced electrolysis

Advanced Electrolysis

Methods have been developed to treat lumps/bumps and lesions with this technology

Skin tags

Milia

Telangiectasia

Seborrhoeic Keratosis

Xanthelasma

Age spots

the procedure

The Procedure

Procedure is conducted in a clean but not sterile environment

Using short wave diathermy between 15-20 RF (Radio frequency)- low to medium diathermy current

One piece stainless steel needle

procedure
Procedure
  • Tip of needle is used to sever the lesion from the skin, using a scraping technique
  • As they are superficial, they tend to lift off the skin easily
after procedure

After Procedure

No discomfort

Occasional inflammation in area treated

Slight erythema

Sometimes bleeds- before scab forms

Scab comes away at 5-7 days

Regular application of witch hazel

Aftercare advice given

aftercare advice given

Aftercare Advice Given

Avoid picking/removing crusting/scabs

Avoid swimming, sun-beds, saunas and fake tans for 48 hours

Avoid skin irritants e.g. perfume, deodorant, perfumed body lotion in treated area for 48 hours

Avoid exfoliation until scabs have come away

Avoid direct sun exposure whilst skin is healing, to prevent hyper/hypo pigmentation- wear a SPF30-50 daily

results so far

Results so far

6 people treated so far (all females- ages 38-52 years)

2 people have completed treatment

4 people still continuing treatment

Treatments all successful

Patient follow up currently between 4wks- 1year post treatment

Variance in scarring remaining dependant on skin type, area treated and adherence to aftercare

All would have the treatment repeated

results at 1 year

Results at 1 year

1 patient at 1 year

No re-growth in treated area

Slight scarring remains in some areas- faded over time- usually where scabs have been picked

Skin is smooth

Significant increase in patient self esteem

conclusion

Conclusion

Advanced Electrolysis is an effective procedure for the removal of Dermatosis Papulosa Nigra

To reach a satisfactory summary further treatment on different ethnic groups is required

Scarring is more likely to occur in some areas than others e.g. abdomen

Not following the aftercare instructions will result in a higher risk of scarring

developments for the future

Developments for the Future

To continue to monitor the long term efficacy of treatment

Work alongside doctor to record possible health/genetic patterns

Investigate different shaped probes for removal techniques

Variances on settings according to skin type and colour
