abstract
aKeloid
Keloid disorder (KD) is a fibroproliferative ailment of the cutaneous
connective tissue secondary to dysregulation in various skin repair
and healing processes. This disorder is characterized by excess collagen and/or glycoprotein depositions in the dermis. Age of onset
of KD is not well documented. Based on clinical observations, various
authors have reported the onset of KD to be between the ages of 10 and
30 years. We report on an African American female who developed bilateral auricular keloids at the age of 9 months. To our knowledge, this
is the youngest age at which a patient has been documented to have
developed KD. Pediatrics 2013;131:e313–e317

Keloids are benign skin tumors that form
as a result of injury or inflammation of
the dermis, typically in individuals who
are genetically predisposed to this disorder. Rarely, keloids may develop de
novo, without a previous noticeable irritation of the skin.
On June 19, 2009, at the age of 3.5 years,
the patient underwent surgery under
general anesthesia, and her keloids
were excised from both earlobes. The
tissue specimens were examined
pathologically and confirmed to be KD
(Figs 2 and 3).
Age of onset of keloid disorder (KD) is
not well documented. Based on clinical
observations, various authors have
reported the onset of KD to be between
the ages of 10 and 30 years.1–3 Mode of
inheritance of KD is not known. Several
theories have been proposed, including autosomal recessive,4 autosomal
dominant with incomplete penetrance,5
and variable expression.
Postoperatively, bilateral pressure earrings were prescribed, but they were
not well tolerated and not used. Within
2 months of surgery, both keloids relapsed, and despite several intralesional
triamcinolone injections, they continued
to grow, mostly anteriorly. On October 6,
2011, at the age of 5 years, the patient
presented to the corresponding author.
On examination, she was found to have
gross bilateral anterior earlobe keloids
(Figs 4 and 5), with minimal posterior
earlobe keloids at the previous surgical
sites.
Keloids are characterized by formation
of excess scar tissue beyond the
boundaries of the precipitating wound.
Although benign, keloids can cause
aesthetic or functional problems, all
of which negatively affect the individual’s quality of life. Our patient developed bilateral auricular keloids when
she was 9 months old, subsequent to
earlobe piercing that had been performed at the age of 3 months. At 6.5
years of age, she is still challenged by
this disorder.
PATIENT PRESENTATION
The female patient described here was
born to African American parents on
January 31, 2006. At 3 months of age, the
pediatrician pierced her earlobes. No
immediate complications or infections
followed. When the child was 9 months
old, her mother detected hard lumps in
both earlobes. On October 18, 2006, the
child’s pediatrician noticed and documented keloids in the posteriors of
both earlobes. Over the next several
months, the keloids grew gradually. At
3 years of age, the patient was referred for surgical removal of the
keloids. Figure 1, the only extant preoperative photograph, depicts the
appearance of the left earlobe keloid
before surgery.

TIRGAN et al
The child had normal growth and development. She was breastfed until the
age of 9 months. She had no other
keloids. The only known family history of
KD was found in the child’s mother.
A single, dark spot on her left upper
arm, on examination, had the appearance of a small, flat keloid.
With parental consent, the child underwent cryotherapy with monthly
topical applications of liquid nitrogen to
her keloids under local anesthesia.
Within 5 months, and after receiving 2
treatments to the right anterior earlobe
keloid and 3 treatments to the left anterior earlobe keloid, both keloids
nearly flattened (Figs 6 and 7). Magnetic pressure disks were prescribed
at this juncture; however, they were not
well tolerated and were not used. By
mid–June 2012, both keloids showed
evidence of early relapse. Cryotherapy
was resumed in late June 2012.
DISCUSSION
This case is a true representation of
a disorder that is difficult to treat. Although keloids can occur at any age,
they tend to develop more rapidly

Sanders et al10 presented data on 15
patients with keloids in the head and
neck region. Among them, a 10-year-old
boy with preauricular keloids was the
youngest. Orimolade et al11 described
the case of a 6-year-old boy who had
developed keloids in the pretibial area
subsequent to chronic osteomyelitis
with purulent discharge. Bermueller

with auricular keloids after surgical excision and/or medical therapy by corticoid injection. A retrospective study at

Ear piercing is by far the leading cause
of earlobe keloid formation in genetically predisposed individuals. Ear
piercing is a widespread practice,
commonly performed by nonmedical
personnel in jewelry shops, stores, and
malls. Parents often choose to have
their daughters’ earlobes pierced at
very early ages. The practice of ear
piercing has never been the subject of
scientific research. The results of a recent online consumer survey,14 however, revealed that 38% of participants
claimed to have had their infant
daughters’ ears pierced. The same
survey indicated that 52% of parents
had chosen to have the piercings performed at jewelry stores; 19% had chosen body-piercing parlors; and only 13%
had elected to have the procedure performed at a physician’s office (Table 2).
Lane et al15 reported that keloids are
more likely to develop when ears are
pierced after age 11 years than when
they are pierced before that age, even
in patients with a family history of KD.
He recommended that patients with
a family history of keloids should consider avoiding ear piercing altogether,
and, if this is not an option, piercing
should be considered during early,
rather than late, childhood.
Although the conclusion of Lane et al15
holds true in a great majority of patients,
the case we have presented here defies
this finding and testifies to the continuing gaps in our understanding of the
pathogenesis and genetics of KD.
Some authors have suggested that
the typical latency in earlobe keloid

development may be due to hormonal
stimulation at puberty16 or during
pregnancy.17 Clearly, neither of these
conditions applied to this patient. One
can only hypothesize that the breastfeeding and passage of mother’s hormones to her infant daughter may have
played a role in the young child’s development of keloids.
KD’s true incidence and prevalence in
the United States are unknown.9 To the
best of our knowledge, no population
study has ever been undertaken to assess this disorder’s epidemiology. Based
on clinical observations, we do know
that the disorder is most common
among Africans and African Americans,16,18 Asians, and Indians from India.
The pathogenesis of KD is for the most
part unknown and poorly understood,
and beyond the scope of this article. The
acknowledged culprit in keloid formation, however, is the wounding of the
skin and subsequent dysregulated
wound healing, a complex, dynamic
process that normally results in the
restoration of the skin’s anatomic
continuity and function.
The tendency of earlobe keloids to
worsen after surgical excision (as exemplified in this case) is most probably
secondary to the retriggering of the
same dysregulated wound-healing
mechanisms by the excision itself: a
new dermal injury more extensive than
the original wound from the piercing.
Keloids may develop in an earlobe’s
anterior, its posterior, or in both sides.
They may appear as pedunculated,
sessile mononodular, or sessile multinodular, or they can take a complex
form. Keloid nodules may be superficial
or have a root and be buried deep inside the earlobe tissue. Generally, it is
agreed that with surgery alone, the
recurrence of earlobe keloids is unacceptably high; therefore, multimodality
treatment protocols have been proposed
to reduce the recurrence rate.19–24
Most therapeutic approaches to earlobe keloids incorporate surgical excision with immediate postoperative
steroid injections, followed by some
form of pressure device, such as
a pressure earring or magnetic disk.
Cryotherapy for earlobe keloids as
monotherapy has also been reported as
effective.25 On keloids’ recurrence after
a multimodal approach, treatment
becomes challenging. As shown in this
case, cryotherapy can be used to
debulk such recurrent keloids.
Although some practitioners use adjuvant radiation therapy to reduce
keloids’ recurrence rate after surgery,16 this modality carries an unacceptable risk of inducing secondary
neoplasms26 and should therefore be
avoided in treating pediatric and young
adult patients.
CONCLUSIONS
Thorough and scientific population and
epidemiology studies of KD are needed.
Scant data exist concerning KD’s incidence and prevalence in children
aged ,10 years. The case presented
here is the youngest patient ever
reported to have developed keloids.
Ear piercing is the leading cause of
earlobe keloid formation in the young.
Although most ear piercings take place
outside of physicians’ offices, many
pediatricians offer this service. Given
the difficulty of treating keloids, pediatricians need to be aware of the risk
of keloid formation and, at a minimum,
should obtain a thorough family history
of KD, especially from African American
and Asian children, before performing
ear-piercing procedures.
