Dear Editor:
Sebaceous hyperplasia (SH) is a common benign skin
lesion composed of sebaceous glands. It is characterized
by a yellow or flesh-toned papule that is commonly found
on the face
1
. Treatment of SH is usually for the cosmetic
reasons only. Although many kinds of treatment modalities
have been applied to treat SH, a successful, long-standing
eradication of SH remains difficult
2
.
A 55-year-old man presented with a several-year history of
multiple papules on the face. Physical examination reveal-
ed multiple yellow or flesh-toned papules on both cheeks
and lateral canthus (Fig. 1A). Magnification with dermato-
scopy showed yellowish papules with overlying telangiec-
tasias. He did not present with subjective symptoms that
are frequently associated with skin lesions. On the basis of
clinical findings, the patient’s condition was diagnosed as
SH. After 1-hour application of topical anesthesia (EMLA
cream, AstraZeneca AB, Södertälje, Sweden), we made a
small, ∼1 mm diameter opening in each papule using the
carbon dioxide laser, then squeezed the papules using an
acne extractor to induce shrinkage of the sebaceous
lobules. Sebaceous contents were easily discharged
through the small papule openings, and the size of the
lesions decreased after squeezing. After squeezing, the
small papule openings were shot by the carbon dioxide
laser to remove the shrunken sebaceous lobules. The
treatment was tolerable to the patient, and there were no
bleeding or other signs of severe tissue damage. Most of
the lesions were flattened after the procedure, and small
crusts made by the carbon dioxide laser disappeared after
10 days of the treatment (Fig. 1B). After 3 months of the
treatment, there were neither signs of recurrence nor
specific side-effects related to the treatment.
Various treatment modalities for SH have been used such
as isotretinoin, cryosurgery, the pulsed-dye laser, and the
carbon dioxide laser
2-5
. However, a long duration of
down-time between treatments is necessary, as various
kinds of laser therapy and cryosurgery inevitably cause
epidermal damage. In addition, adverse effects such as
persistent erythema, edema, infection, and persistent
hyperpigmentation are not uncommon. Although the
non-ablative lasers and isotretinoin can be used to avoid
these limitations, the high cost may be a burden to
patients. In this case, we used a simple method that
required making an opening in the multiple SHs, using a
carbon dioxide laser, with the subsequent squeezing by
an acne extractor. Different from the conventional uses of
the carbon dioxide laser, we used the laser only to make
very small openings and to eradicate the shrunken
sebaceous lobules. Because we made minimal epidermal
changes, there were no side-effects related to the laser
treatment such as persistent erythema, edema, infection,
and persistent hyperpigmentation. In addition, the patient
did not feel discomfort during the procedure.
In summary, we report a case of SH that was effectively
improved by the pin-hole technique with the carbon
dioxide laser. We think that this method may be used as
an alternative therapy for the treatment of SH. Further
study is warranted to determine the longevity of the
clinical results observed.
