Abstract
Dermal scars follow different kinds of injury to the skin including that of the breast. Any lesion
on the female breast raises suspicion especially when it mimics breast cancer. Nodular keloidal
lesions on the breast may generate some anxiety and scare in the light of public awareness and
aggressive preventive campaigns about breast cancer. The psychosocial strain of a false alarm can be
severe.
Eleven cases of hypertrophic/keloidal lesions of the breast were examined for pattern and extent
among female patients presenting at a dermatology clinic who expressed fears about the possibility
of underlying disease apart from the scar lesion. None of the cases had any clinical evidence to
suggest breast malignancy. Future and larger studies may need to evaluate the anxiety cost of breast
cancer scare among black women who develop scars on the breast.
Introduction
For women, the breasts represent an important part of the body, especially from the sexual,
functional and cosmetic point of view, having also an important emotional and psychological
connotation [1]. Breasts have been a symbol of femininity and sexuality since civilization began, so
it is not unusual for a woman with any breast lesion to feel that the disease has attacked her body
image along with her breast tissue [2]. Women are self-conscious about their breasts and are on the
lookout for any suspicious lesions that mimic breast cancer. False alarms are not only
psychologically stressful, but they also often force patients to undergo uncomfortable follow-up tests
or even surgery, only to discover that they are cancer free.
Scars arise after almost every dermal injury including tattoos, superficial scratches and
complicate surgery in predisposed individuals. Keloids can develop in any place that an abrasion has

occurred as a result of pimples, insect bites, scratching, burns, or other skin trauma. They are more
common in some sites such as central chest, the back and shoulders and the ear lobes [3]. Individuals
with pigmented skin are more prone to severe skin scarring than white people [3]. Women are more
likely to develop heavy scar as are young people under the age of about thirty [4]. There is also a
genetic susceptibility to keloids [5].
A scare means sudden mass fear and anxiety over anticipated events or situation: a general state
of alarm; a panic: when a subject receives a lot of public attention and worries many people, often
unnecessarily [6]. In a situation where "early detection" is emphasized and where new high-tech
screening tests are being promoted for breast cancer, it is increasingly possible that everyone with
any breast lesion will experience a cancer scare. Studies on how people react when they endure a
cancer scare have had mixed results. The psychosocial strain of a false alarm can be severe and may
continue after women are declared free from cancer. Many women experience anxiety, worry,
despondency, sleeping problems, and negative impact on sexuality and behaviour, and changes in
their relationships with family, friends, and acquaintances and in existential values [7,8]. For every
cancer survivor, there are several "cancer scare survivors" who are convinced, that they may have
cancer when they do not [8].
Can keloidal/hypertrophic scar generate a scare of breast cancer? Keloids are new growths even
though benign. Any new lesion on the breast draws attention for clarification. Severe keloidal lesions
may be so aggressive that they may be reminiscent of neoplastic disease [9]. Since keloid scars are
nodular skin lesions that in severe forms resemble neoplasms, they can cause much physical and
mental distress especially when located in sensitive areas like the breasts and nipples [9]. There is a
need to highlight breast keloid as a possible avenue for breast cancer scare. Since the breasts are a
common site for the keloid prone, there is a need for the caregiver to prioritize how to allay the fears
of the affected women.
Case Selection
Eleven cases of hypertrophic/keloidal lesions of the breast were examined for the pattern and
extent among female patients presenting at a dermatology clinic who expressed fears about the
possibility of underlying disease apart from the scar lesion. The pictorial documentation of the
different cases was to show the varieties in location and extent among women with breast scars over
a time period. The predisposing factors for the emergence of keloidal breast lesions and the body
sites affected were identified and documented. None of the patients had any past medical history of
breast cancer. A thorough examination of both breasts was carried out by the attending dermatologist
with tissue diagnosis where necessary for confirmation.
Results
Eleven out of seventy cases (16%); diagnosed with hypertrophic/keloidal scars over a five year
period had the breasts affected (Figures 1-11). All eleven cases were female gender. The age range
was between 20 to 60years. There was a family history of keloid in eight out of the eleven but no
family history of breast cancer. There was no history of breast lump, dimpling, nipple eczema or
nipple discharge in any of the patients. Symptoms of the scar lesions included itching, pain,
perceived disfigurement and fear of breast cancer. In one case keloidal lesions followed a surgical
intervention to remove an initial smaller keloid resulting in the recurrence in a linear fashion along
the excision lines and stitches (Figure 9a and 9b).

Palpation of both breasts did not reveal any breast lump or significant axillary
lymphadenopathy. Five out of the eleven cases had only one breast affected while the remaining had
bilateral scar lesions on both breasts. Four of the cases had hypertrophic scars (Figure 1- 4) while the
remaining seven had keloidal scars (Figure 5-11). The nipple was the main involvement area in one
of the cases with bilateral breast keloidal scar (Figure 6) and it started following a period of
breastfeeding. There was anxiety about the exact nature of the scarred lesions in all cases. Skin
biopsy confirmed the diagnosis of scar tissue in relevant cases.

Discussion
Hypertrophic scars and keloids are common problems, especially in individuals of African
descent [3]. Both keloids and hypertrophic scars are characterized by abundant deposition of
collagen and glycoprotein. Keloids differ from hypertrophic scars both clinically and histologically.
Clinically, keloids extend beyond the original wound, whereas hypertrophic scars remain within the
borders of the original wound [10]. Histologically, keloids are composed of disorganized, thick,
Page 8 of 12
hyalinized collagen with a prominent mucoid matrix, whereas hypertrophic scars are characterized
by fewer, more organized, collagen fibers with a scanty mucoid matrix. The fibroblast concentration
has also been reported to be more prominent in hypertrophic scars [11].
Spontaneous Keloidal scars may occur but most follow varieties of trauma from sometimes
forgotten or unnoticed insults to the skin. Surgical procedures on the breast including breast
augmentation, reduction, therapeutic excision and radiation therapy can result in breast keloids. All
causes of primary breast dermatosis may result in scarring on healing in the predisposed individual.
In most of the times the underlying injury may not be identifiable. In one study six out of seventy
patients with scleroderma exhibited keloidal lesions [12].
Dermatitis artefacta a psycho- dermatological self inflicted wounds affecting the breast in 27
women was reported [13]. The patient usually denies the participation in the injury and there is
absence of a rational motive for such process. Hypertrophic/keloidal scars may follow such
mutilation of the skin but of the 27 reported cases in the reported series however, none presented
clinically with keloidal or hypertrophic lesions of the breast. The clinical presentations included
blisters, cigarette burns, excoriations and dermatitis. The author concluded that self-induced
dermatitis of the breast is of difficult diagnosis and should be considered when organic disorders
have been excluded. This may explain the origin of the primary wounds of some scars whose injury
may not have been identifiable.
The skin of the breast is subject to both inflammatory and neoplastic process that any skin is
subject to. One of the primary goals of diagnosing a breast skin lesion is to rule out a malignant
process such as metastatic carcinoma or Paget’s disease of the breast, a non-invasive cancer but
associated with deeper cancers. Paget’s disease of the breast is a malignant condition that outwardly
may have the appearance of eczema, with skin changes involving the nipple of the breast. Paget’s
disease can cause flaky or scaly skin on the nipple, straw-colored or bloody nipple discharge, skin
and nipple changes in only one breast or the flattened nipples [14]. Healing of the eczematous nipple
may be followed with formation of scars.
Unusual keloid-like nodules or scars on the chest that fail to respond to therapy may be primary
or metastatic malignancies, and adequate histological verification should be obtained to avoid delay
in the proper treatment [15]. Carcinoma en cuirasse was reported to have presented like a keloid in a
63year old woman [15]. It is a form of metastatic cutaneous breast malignancy occurring most
commonly on the chest as a recurrence of breast cancer, but it can be the primary presentation.
Histologically, the tissue resembles fibrosis with a few tumor cells exhibiting an ’’Indian file’’ pattern,
where the tumor cells forms small lines between collagen bundles. The tumor cells are often
overlooked as they appear much like fibroblasts, but with larger, angulated, more deeply basophilic
nuclei [15]. The ability to identify cutaneous presentations of breast carcinoma and to obtain
histologic verification is critical to avoid delay in proper treatment.
A post excisional biopsy scar may occur on the breast producing various degrees of skin
thickening, subcutaneous scarring and dystrophic calcification especially if it was infected. This will
result in visible changes during radiological investigations and mammography. A surgical scar is an
area of fibrosis that is seen on mammogram as an area of architectural distortion or an ill-defined
mass mimicking carcinoma. A surgical scar should be located in relative proximity to the incision
site. Finding of a post-surgical scar in patients with breast cancer treated with conservation therapy
may be suspicious of tumor recurrence. On mammography, a benign surgical scar looks similar to
carcinoma. A hypo echoic tract connecting from the mass lesion to the thickened skin at the incision
site is helpful in diagnosis of a surgical scar. The atypical may be suspicious enough to cause a scare.

It is important for radiologists to be familiar with the spectrum of mammographic abnormalities
associated with post biopsy changes and keloidal scars on the breasts [16,17].
Some therapeutic modalities are common to both breast cancer and keloidal scars. The basis for
their use in patients with keloidal scars may generate some anxiety in the patient if appropriate
counseling is absent. Tamoxifen, a synthetic, nonsteroidal antiestrogen anti breast cancer drug has
been shown to inhibit keloid fibroblast proliferation and decrease collagen production [18]. The
addition of Tamoxifen may lead to improved wound healing in keloids by decreasing the expression
of TGF-b1 [18]. Topical estrogen has been associated with keloid formation. When topical estrogen
is applied to normal elderly skin wound margins immediately before wounding and for 24 hours
post-wounding it increased the extent of wound heal. The deposition of matrix at day 7 was
enhanced in elderly males and females by topical estrogen. Estrogen treatment stimulates matrix
deposition [19].
Radiotherapy, also used in treatment of breast cancer, was first introduced as a treatment for
keloid scars in 1906 [20]. Keloids remain the commonest type of benign diseases treated by
radiotherapy [21]. This can be attributed to the fact that these scars are particularly refractory to most
other treatment modalities. Radiation can be used as a monotherapy or combined with surgery to
prevent recurrence of keloids following excision. Radiotherapy as monotherapy has been
controversial largely due to concerns over post irradiation cancer occurring in some patients [22].
There are only anecdotal reports in the literature of malignancies following treatment of keloids with
radiotherapy. Botwood et al report a case of a patient who developed bilateral breast carcinomas 30
years after treatment of chest wall keloids with radiotherapy [23].
Aggressive or morbid keloids, a severe variant of familial keloid is more common in darker
skinned individuals than in white subjects, further advocating the genetic component [24].
No single therapeutic modality is best for all keloids. The location, size, and depth of the lesion;
the age of the patient; and the past response to treatment determine the type of therapy used.
Prevention is key, but therapeutic treatment of hypertrophic scars and keloids includes occlusivee
dressings, compression therapy, intralesional corticosteroid injections, cryosurgery, excision,
radiation therapy, laser therapy, interferon (IFN) therapy, 5-fluorouracil (5-FU), doxorubicin,
bleomycin, verapamil, retinoic acid, imiquimod 5% cream, tamoxifen, tacrolimus, botulinum toxin,
and over-the-counter treatments (eg, onion extract; combination of hydrocortisone, silicon, and
vitamin E). Other promising therapies include antiangiogenic factors, including vascular endothelial
growth factor (VEGF) inhibitors (eg, bevacizumab), phototherapy (photodynamic therapy [PDT],
UVA-1 therapy, narrowband UVB therapy), transforming growth factor (TGF)-beta3, tumor
necrosis factor (TNF)-alpha inhibitors (etanercept), and recombinant human interleukin (rhIL-10),
which are directed at decreasing collagen synthesis [25].
Conclusion
Keloid is both physically and emotionally stressful for the patient and worse still when it
involves a sensitive part of the body that defines feminity. Breast lesions including
hypertrophic/keloidal scars may mimic cancer of the breast and cause a scare..
Future studies may need to evaluate the anxiety cost of breast cancer scare among black women
who develop scars on their breasts.
