A desmoid tumour associated with a breast prosthesis

Desmoid fibroma simulating malignant breast neoplasm: A case report and literature review

INTRODUCTION

Desmoid fibroma (DF) is a disorder characterized by strong clonal proliferation of myofibroblasts and fibroblasts. We describe a case of DF that mimicked a breast tumor, along with a review of the literature on the clinical manifestation, diagnostic process, and course of therapy for this combative disease.

CASE REPORT

A 34-year-old female patient with breast lump at the junction of the upper quadrants of the left breast. After the diagnosis of DF, it was decided to perform a sectorectomy of the left breast associated with post-quadrant reconstruction, with immunohistochemistry and findings compatible with DF.

DISCUSSION

Clinically manifests as a solid mass that is often painless and occasionally adherent to the chest wall. A treatment strategy should be idealized for each patient. Thus, there is the possibility of performing radical surgery for resection and/or radiotherapy, and surgery may be followed by radiotherapy.

Desmoid Tumor and Silicone Breast Implant Surgery: Is There Really a Connection? A Literature Review

BACKGROUND

Desmoid tumors are borderline tumors of the connective tissue, arising in the musculo-aponeurotic stromal elements. A desmoid tumor (DT) has an infiltrative and locally aggressive growth pattern and usually does not metastasize; however, it has a high recurrence and complication rate. DT located in the breast (BDT) represents a rare extra-abdominal form. Recently, the presence of breast silicone implants was suggested by several researchers as a risk factor for developing BDT.

OBJECTIVES

The goal of this review is to investigate the possible correlation between BDT and breast implant surgery.

METHODS

We conducted a literature review of BDT-reported cases, associated with breast implant surgery.

RESULTS

The search revealed 36 cases of BDT associated with silicone breast implants.

CONCLUSIONS

Based on the reviewed data, the incidence of BDT following breast implant surgery is lower than BDT in the general population. At the moment, a possible association between breast implants and the development of breast desmoid tumors cannot be unequivocally confirmed. A world registry with accurate documentation of each case of BDT associated with breast implant surgery should be performed for future investigation.

Radiologic images of an aggressive implant-associated fibromatosis of the breast and chest wall: case report and review of the literature

Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision. Unlike previously reported imaging findings, magnetic resonance imaging revealed an oval circumscribed mass with fringe-like internal architecture. We provide a review of the literature and discuss the imaging features of implant-associated fibromatosis of the breast.

Desmoid Tumor of the Chest Wall Mimicking Recurrent Breast Cancer: Multimodality Imaging Findings

Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy. The desmoid tumor is a rare benign tumor that should be considered in the differential diagnosis of malignant local tumor recurrence after breast cancer operation. Biopsy was required for accurate diagnosis and wide local excision was its appropriate surgical management.
