Nipple-sparing skin-sparing mastectomy and vertical latissimus dorsi flap reconstruction for bilateral fibromatosis of the breast

Bilateral breast desmoid-type fibromatosis, case report and literature review

BACKGROUND

Breast desmoid-type fibromatosis (BDF) is a rare mesenchymal tumor accounting for only 0.2% of solid breast tumors. It is classified as an intermediate tumor because it is locally aggressive but has no metastatic potential. Its diagnosis is often difficult because it shares many clinical and radiologic aspects with breast carcinomas and therefore relies on anatomopathological analysis which may be supplemented by genetic analysis. The treatment of BDF has considerably evolved in the past years. While surgery was the cornerstone of the management prior to the 2000s, recent data have shown the value of active surveillance (AS) from the time of diagnosis. Indeed, after 2 years of AS, the progression-free survival (PFS) of the disease is identical or superior to surgery. Moreover, spontaneous regression has been observed in 30% of patients undergoing AS. In case of disease progression, surgery can be considered on a case-by-case basis, as well as systemic treatments.

CASE DESCRIPTION

We present a case of bilateral BDF affecting a 20-year-old woman for whom the first suggested treatment was bilateral mastectomy with reconstruction. After a second opinion, the decision was revised and AS was initiated. Almost 3 years after the onset of AS, tumors have shown a continuous regression.

CONCLUSIONS

This case demonstrates the need for experience in the management of mesenchymal tumors to avoid overtreatment by mutilating surgeries which promote recurrence. Moreover, to our knowledge, very few cases of bilateral BDF have been published to date. It thus seemed relevant for us to report this rare case which supports the interest of AS for DF, as recently advised by the Desmoid Tumor Working Group guidelines.

Application of Periareolar Mammaplasty with the Tissue Folding Technique in Breast Reshaping following Polyacrylamide Hydrogel Removal

Background

Polyacrylamide hydrogel (PAAG) was used as an injectable implant for augmentation mammoplasty for over 30 years, but its use was ceased due to various related complications. The only way to treat these complications is PAAG removal, but this causes breast ptosis, nipple retraction, breast asymmetry, and skin laxity.

Objectives

This article reports a new technique for breast reshaping after PAAG removal without prosthesis implantation.

Method

From January 2015 to June 2018, twenty-three patients underwent periareolar mammoplasty with the tissue folding technique (PMTFT) for breast reshaping after PAAG removal. Postoperative breast shape and the degree of satisfaction of the patients were evaluated during follow-up.

Results

All patients recovered well without severe complications. All patients were satisfied with their postoperative breast shape and their symptoms were relieved after surgery.

Conclusions

PMTFT provides satisfactory postoperative breast shape results. Economical, practical, and technical advantages were found over traditional prosthesis-mediated breast reconstruction. PMTFT can be an ideal surgical choice in appropriate cases.

Autologous reconstruction following nipple sparing mastectomy: a comprehensive review of the current literature

As surgical methods continue to evolve and patients become more educated consumers of their medical care, both oncologic breast surgeons and reconstructive plastic surgeons should understand the current options for surgical management of breast cancer. This review evaluates the current autologous breast reconstruction options following nipple sparing mastectomy (NSM). A comprehensive review of the current literature discussing autologous reconstruction after NSM was performed. Fat grafting alone has been used to reconstruct small to medium sized-breasts over multiple injection sessions. Goldilocks mastectomy-like reconstructions can be used for larger, more ptotic breasts. Pedicled latissimus dorsi (LD) flaps can be used, but usually need to be modified to ensure sufficient breast volume. While the lower abdominal tissue remains the most common donor site in free tissue transfer, other donor sites can be used if there is insufficient volume or inadequate perforators. Periareolar incisions are associated with the highest rates of overall complications and nipple areola complex necrosis. It has not been determined whether implant-based or autologous reconstructions have lower complication rates. Both prior radiation and large, ptotic breasts present unique challenges during reconstruction. Overall, there is a high rate of patient satisfaction with breast reconstruction following NSM. Autologous breast reconstruction after NSM is a safe method of breast cancer surgical management with aesthetically excellent results. Multiple techniques have been described along the reconstructive ladder. Special consideration should be given to choices of incision, previously irradiated breasts, and large, ptotic breasts.

Breast fibromatosis, an unusual breast disease

Fibromatosis is a benign tumor that rarely affects the breast and is an unusual site for its occurrence. Whilst the definite etiology of breast fibromatosis is unclear, it may present itself following surgical trauma or silicone implant. Wide local excision with adequate safety margins is considered the standard of care. We review three cases of breast fibromatosis who were presented to and operated in the Oncology center, Mansoura universty (between April 2014 and August 2016). Two of these cases underwent wide local excision and primary closure of the defect whilst the other one was reshaped by mini latismuss dorsi flap.

Bilateral desmoid tumor of the breast: case seriesand literature review

Background

Desmoid tumor of the breast is very rare and locally aggressive but has no distant metastasis. Bilateral lesions are extremely rare, found in only 4% of patients. Two cases of bilateral desmoid tumor of the breast are reported. The clinical presentation, diagnosis, imaging, treatment, and follow-up outcomes of recurrence as well as a brief literature review are provided.

Case reports

Case 1 is a 31-year-old woman who presented with nipple retraction. An ultrasound revealed BIRAD V in both breasts. She underwent a bilateral excisional biopsy under ultrasound mark with the pathology result of extra-abdominal desmoid tumor in both breasts. The patient had a bilateral mastectomy with silicone implantation due to the involved margins by excision. She remained tumor free after 7-year follow-up. Case 2 is a 28-year-old woman who presented with a lump on her right breast that she had discovered ~2 months earlier. An ultrasound showed a spiculated mass in the right breast and some circumscribed hypoechoic masses in both breasts. A bilateral breast excision was done. The pathology result was an extra-abdominal desmoid tumor. She had recurrence on both sides and underwent a mastectomy and silicone implantation. The tumor has not recurred after 1-year follow-up.

Conclusion

Imaging cannot distinguish between benign breast lesions and malignancy. Pathology results are helpful in making a definitive diagnosis. Given that the desmoid tumor is locally aggressive, a local excision with clear margins is recommended. Chemotherapy and hormonal treatment are controversial.
