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.

Imaging-pathologic correlation of diseases in the axilla

OBJECTIVE

This article reviews the imaging and histopathologic findings of various axillary diseases and suggests management guidelines for radiologists based on imaging findings with clinical correlation.

CONCLUSION

Although axillary diseases may reveal nonspecific imaging findings, a knowledge of the characteristic radiologic manifestations of specific diseases according to anatomic origin (nodal, accessory breast, adipocytic, fibrous, nerve, vascular, stromal, and dermal) and postsurgical lesions aids in establishing an appropriate differential diagnosis and determining whether intervention is necessary.

An unusual case of fatty liver in a patient with desmoid tumor

A desmoid tumor, also known as aggressive fibromatosis, is a rare benign neoplasm that arises from fascial or musculoaponeurotic tissues. It can occur in any anatomical location, most commonly the abdominal wall, shoulder girdle and retroperitoneum. The typical clinical presentation is a painless mass with a slow and progressive invasion of contiguous structures. It is associated with a high local recurrence rate after resection. Many issues regarding the optimal treatment of desmoid tumors remain controversial. Aggressive surgical resection with a wide margin (2-3 cm) remains the gold standard treatment with regard to preserving quality of life. Radiotherapy alone has been shown to be effective for the control of unresectable or recurrent lesions. Desmoid tumors tend to be locally infiltrative, therefore, the fields must be generous to prevent marginal recurrence. The radiation dose appropriate for treating desmoid tumors remains controversial. We present a 25-year-old Caucasian man with local recurrence of a desmoid tumor after repeated surgical resection, treated with radiotherapy. The patient achieved complete tumor regression at 4 mo after radiotherapy, and he is clinically free of disease at 12 mo after the end of treatment, with an acceptable quality of life. The patient developed short bowel syndrome as a complication of second surgical resection. Consequently, radiotherapy might have worsened an already present malabsorption and so led to steatohepatitis.

Bilateral breast fibromatosis: case report and review of the literature

Fibromatosis or desmoid tumor is a benign, slow-growing fibroblastic neoplasm originating from musculoaponeurotic stromal elements. These tumors are characterized by an infiltrative and locally aggressive growth pattern, frequent recurrences, but no metastatic potential. The etiology is unknown, but these tumors have been associated with trauma and genetic disorders. Breast fibromatosis is exceedingly rare and often misdiagnosed, comprising only 0.2% of breast tumors. Clinically, it might mimic other breast lesions, such as carcinoma. Only approximately 6 case series and 100 case reports of this disorder affecting the breast are documented, and only 5 cases of bilateral breast fibromatosis have been reported. We describe the case of a 20-year-old woman who presented to our institution with firm, nontender masses palpable in both breasts. Prior ultrasound was suspicious for carcinoma, and breast core biopsies were suggestive of phyllodes tumor. An excisional biopsy was necessary to establish the diagnosis of breast fibromatosis for both masses. A review of articles published on desmoid tumors and breast fibromatosis was performed with emphasis on articles published in the last 10 years. Fibromatosis should be considered in the differential diagnosis of patients presenting with hard breast lumps suspicious of other diseases.

Chest wall tumors: radiologic findings and pathologic correlation: part 2. Malignant tumors

Malignant chest wall tumors are classified into eight main diagnostic categories: muscular, vascular, fibrous and fibrohistiocytic, peripheral nerve, osseous and cartilaginous, adipose, hematologic, and cutaneous. However, there are malignant tumors that arise in the chest wall and that do not fit well in any of these categories (eg, Ewing sarcoma and synovial sarcoma). Malignant chest wall tumors typically manifest as painful, rapidly growing, large palpable masses. Chest radiography, the technique most often used for initial evaluation, can be helpful for detecting cortical destruction. However, computed tomography is more sensitive than chest radiography for detecting calcified tumor matrix and cortical destruction. Magnetic resonance imaging often allows more accurate delineation and localization of the tumor and is helpful for determining the presence and extent of tumor invasion and for tissue characterization. Although the imaging features of many malignant chest wall tumors are nonspecific, knowledge of the typical radiologic manifestations of these tumors often enables their differentiation from benign chest wall tumors and occasionally allows a specific diagnosis to be suggested. The article reviews the clinical and imaging features of the most common malignant chest wall tumors and presents images collected at a single cancer referral center.
