Total mastectomy and chest reconstruction for a rapidly progressing giant phyllodes tumor with skin necrosis: a case report

Giant Benign Mammary Phyllodes Tumor: Report of a Case and Review of the Literature

Phyllodes tumor of the breast is an infrequently encountered fibroepithelial neoplasm, which accounts for 0.3–1% of all tumors. Few case reports have described the occurrence of giant phyllodes tumor. To our knowledge, about 20% of phyllodes tumors would be considered giant benign. Complete surgical excision is the standard of care for giant benign phyllodes tumors; axillary lymph node metastasis is rare, and dissection should be limited to patients with pathologic evidence of tumor in the lymph nodes. We report the case of a 40-year-old Mexican woman with giant mammary tumor who underwent a right total mastectomy. The pathology results showed a benign phyllodes tumor 4,857 g in weight and 40.2 × 36.3 × 15 cm in size. We do not suggest adjuvant radiation therapy for patients with benign phyllodes tumors that are widely excised. A review of the pertinent literature was performed.

Review of Procedures for Reconstruction of Soft Tissue Chest Wall Defects Following Advanced Breast Malignancies

The purpose of this article is to review closure options for complex chest wounds in patients with locally advanced breast cancer. Experiences of the plastic and oncologic surgery teams at Moffitt Cancer Center were reviewed, and the literature researched for various surgical options of complex chest wound closure. Multiple treatment modalities exist for reconstruction of complex chest wall wounds with the external oblique and V-Y latissimus dorsi musculocutaneous advancement flaps serving as workhorses in reconstruction. Treatment of cancer has moved from simply a surgical solution to include other modalities such as hormonal therapy, chemotherapy, and radiation—the latter 2 having serious consequences for wound healing. A team approach and knowledge of available flap options are vital for closure of complex wounds in a timely manner. Appropriate planning can optimize the primary goal of the oncologic surgeon to remove the cancer and the plastic surgeon’s objective to reconstruct the defect and achieve a closed, durable wound prior to chemotherapy and radiation. We present the experience at the Moffitt Cancer Center in reconstructing challenging chest defects and review the reconstructive ladder.

Application of a rhomboid flap for the coverage of defects after malignant breast tumor resection: A case report

Resection for locally advanced breast cancer (LABC) or malignant phyllodes tumors may cause a large skin defect with bone exposure. Although skin grafts are frequently used to cover such defects, they can result in poor cosmetic outcomes and graft acceptance is dependent upon the condition of the recipient site. To overcome the limitations of skin grafts, various flaps have been developed to cover such defects. The present study used a rhomboid flap for the coverage of skin defects after mastectomy and breast-conservative surgery (BCS). A total of 11 patients with malignant breast cancer underwent reconstructive surgery using the rhomboid flap between September 2011 and December 2013 (mastectomy, 9 patients; BCS, 2 patients). Skin resection size, axillary lymph node dissection, bone exposure, length of surgery, wound complications and whether preoperative/postoperative adjuvant therapy was received were analyzed. The maximum size of skin defect covered with the rhomboid flap in the present study was 20×20 cm. There were no major wound complications and all patients underwent postoperative adjuvant therapy on schedule. During BCS, a portion of the flap was used for augmentation of the breast, in addition to coverage of the skin defect, which resulted in good cosmetic outcomes. The rhomboid flap can be quickly and easily fashioned, and it does not require any special instruments.

The largest and neglected giant phyllodes tumor of the breast-A case report and literature review

INTRODUCTION

Phyllodes tumours are rare fibro-epithelial lesions. The role of the pathologist in the preoperative diagnosis of phyllodes tumours of the breast is critical to appropriate surgical planning. Wide local excision or mastectomy with adequate margin remains the treatment of choice. Local recurrence occurs in approximately 10- 16.1% of patients (Wei et al., 2014) [1] and distant metastases occurs in 6.3-31% of patients with malignant phyllodes tumours (Wei et al. (2014), Chaney et al., 1998) [1,2] but only in 4% of all phyllodes tumours (Salvador et al., 1989) [3]. Emphasis should be given in early diagnosis and intervention to decrease morbidity and mortality.
