Summary: Cancer of a male breast represents less than 1% of all breast cancer. As with to female patients, mastectomy in men creates a substantial emotional burden. Breast reconstruction may improve the patient’s psychological well-being, compliance with adjuvant treatments, and overall outcome. However, due to the unique anatomy of the male breast, standard reconstructive strategies using anatomic or prosthetic modalities are not entirely applicable. We describe a case of a 68-year-old male patient who underwent successful unilateral breast reconstruction solely with fat grafting technique.

It is estimated that in 2014, about 2360 new breast cancer cases causing 430 deaths will have been diagnosed among men in the United States.1,2 The diagnosis of breast cancer creates a considerable psychological burden and reduces the quality of life.3,4 Major depressive disorder is a frequent but often unrecognized and untreated condition among breast cancer patients, which causes amplification of physical symptoms, additive functional impairment, and poor adherence to treatment regimens.3,4 The primary standard treatment in male breast cancer consists of a modified radical mastectomy with axillary node sampling and/or dissection, which leaves an asymmetrical chest.1,2,5 Because breast reconstruction reduces the disfigurement, it is appropriate to also consider restoration of the breast in the male patient. However, standard autologous and/or prosthetic reconstructive approaches may not be adequate to recreate the unique shape and symmetry of the male chest wall. We present a case of a 68-year-old psychologist and body builder who underwent a successful unilateral breast reconstruction with fat grafting.

CASE REPORT

A 68-year-old male patient was diagnosed with a 1 × 2 cm subareolar ER/PR positive and estrogen receptor (ER)/progesterone receptor (PR) positive and human epidermal growth factor receptor 2 (HER2/neu) negative invasive ductal carcinoma. There was no skin involvement or nipple discharge. The initial excisional biopsy was coupled with a sentinel lymph node biopsy, which was negative for metastases. The patient was then offered a completion mastectomy. Due to the patient’s considerable concerns about chest wall appearance after mastectomy, immediate staged breast reconstruction with fat grafting was offered. Surgical interventions were carried out approximately 5 months apart.

Staged Surgical Approach

Initially, 70 ml of fat graft from the abdomen was deposited in strands under the preserved fascia of the left pectoralis major muscle (Fig. 1). The fat graft was acquired and processed according to Coleman’s method including manual fat harvesting and centrifugation.6 The mastectomy wound was closed in standard fashion over a drain. After 5 months (Fig. 2), additional 141 ml of fat graft was injected into the tissues of the left chest wall defect. The last stage carried out after subsequent 5 months and consisted of liposuction of 70 ml of excessive tissues from the left breast and transfer of 20 ml of fat graft into a residual contour defect. During the last stage, nipple reconstruction using a modified skate flap and skin graft from the patient’s groin was performed.

Follow-up

The patient’s recovery after each procedure was uneventful. The reconstructed breast mound remained entirely soft without palpable nodules suggestive of fat necrosis. The reconstructed nipple, however, developed partial necrosis but did not require revision. At 6-month follow-up, the patient was very satisfied with his reconstructed breast, which became his preferred side (Fig. 3).

DISCUSSION

Treatment of breast cancer is emotionally and physically disabling regardless of sex.3,4 Moreover, impaired physical activity and emotional dysfunction associated with breast cancer negatively affect patient survival.7 On the other hand, breast reconstruction after mastectomy has been shown to reduce cancer-specific death.8 Although methods of reconstruction after mastectomy in women are well described, postmastectomy deformity of the male chest has not received sufficient attention. The likely explanation of this fact is the relative rarity of male breast cancer and different societal roles and expectations. In our patient, we achieved total breast reconstruction with 3 sessions of liposculpting, yielding a satisfactory outcome.

Fat grafting is a straightforward technique associated with low complications and minimal donor site morbidity compared with other techniques.9,10 It allows the surgeon to customize the surgical approach to address the distinctive defect of the male chest. Due to low volume demands, reconstruction of the male breast intuitively may require small graft volumes and fewer operative sessions. In addition, fat represents a filling material with ideal properties—it is cheap, biocompatible, and lacks toxicity. It can provide a natural feel and great cosmesis, and, if needed, can be easily removed.11–13

Fat grafting is not free of challenges because the “behavior” of transplanted fat is not entirely understood. Fat graft take varies greatly, frequently requiring several procedures.11,13–16 Moreover, the amount of fat transferred in 1 session is limited as overfilling results in fat necrosis leading to cyst formation and possible infection.17 Other potential complications of fat grating include necrotic lumps and calcifications thought to obscure cancer surveillance.11,13,18 However, Parikh et al19 conducted a retrospective analysis of 286 breast cancer patients reconstructed with fat grafting who underwent imaging of a palpable lesions and found that the negative predictive value for malignancy of avascular lesions with circumscribed margins (characterizing fat necrosis) was 100%. Additionally, the authors provided a detailed imaging classification of radiographic features distinguishing benign and malignant lesions.19 Similarly, the American Society of Plastic Surgeons Fat Graft Task Force recognized high reliability of imaging in ruling out malignant findings but also recommended biopsy in cases of uncertainty.14,16

The potential of fat grafting to the breast coinciding with cancer has been examined in the literature. In a study of 1112 breasts in 866 breast cancer patients reconstructed immediately with tissue expander and fat graft, there were no cases of local recurrence after over a 40-month follow-up.20 Similarly, in another series of 880 patients who underwent breast lipomodeling, there were no instances of cancer after 10-year follow-up.21 Although relationship between local cancer recurrence and fat graft is rare,20,22 the possibility for transferred adipocytes and particularly adipose-derived stem cells to cause malignant transformation has been investigated.23,24 The available data suggest that the critical factor determining whether regeneration therapy (eg, adipose-derived stem cells) enhances tumor growth is the condition of the remaining tumor: active disease is promoted, whereas dormant tumor is insensitive.23 Clearly, caution should be exercised when applying fat cells into a prior tumor bed.23,24

In conclusion, even though the behavior of transferred fat is not well understood, fat grafting is a very powerful reconstructive modality to recreate the unique shape of the male breast after mastectomy.
