Marked eosinophilia as initial presentation of breast implant-associated anaplastic large cell lymphoma

Nonhormone-Related Histologic Findings in Postsurgical Pathology Specimens From Transgender Persons

OBJECTIVES

The objective of this review is to characterize the literature addressing postprocedural complications in persons undergoing gender-affirming surgeries.

METHODS

A literature search using the OVID MEDLINE and PubMed databases was performed to identify all studies describing histologic findings in surgical pathology specimens from transgender persons from 1946 to April 2021. The studies describing postsurgical complications were categorized based on anatomic site, type of complication, study design, publication region, and date.

RESULTS

Thirty-nine studies describing postsurgical complications in transgender women were identified. The most common sites of postprocedural pathology included the breasts and neovagina, with additional studies including buttocks and thighs, cutaneous sites, and the pulmonary system. Most of the literature comprised case reports, followed by case series and comparative studies. The search did not identify any studies of complications secondary to masculinizing surgeries.

CONCLUSIONS

This body of literature is small but growing. Most studies are case reports. There are significant gaps in the literature. The literature in this area is not yet mature enough to support a meta-analysis.

Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL): Review of Epidemiology and Prevalence Assessment in Europe

BACKGROUND

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) epidemiologic studies focus on incidence and risk estimates.

OBJECTIVES

The aim of this study was to perform a thorough literature review, and to provide an accurate estimate of BIA-ALCL prevalence in Europe.

METHODS

We searched PubMed, Web of Science, SCOPUS, and Google Scholar databases to identify publications reporting BIA-ALCL epidemiology. Research was conducted between November 2019 and August 2020. European prevalence was assessed as the ratio between pathology-confirmed cases and breast implant-bearing individuals. The Committee on Device Safety and Development (CDSD) collected data from national plastic surgery societies, health authorities, and disease-specific registries to calculate the numerator. The denominator was estimated by combining European demographic data with scientific reports.

RESULTS

Our research identified 507 articles: 106 were excluded for not being relevant to BIA-ALCL. From the remaining 401 articles, we selected 35 that discussed epidemiology and 12 reviews. The CDSD reported 420 cases in Europe, with an overall prevalence of 1:13,745 cases in the 28 member states of the European Union (EU-28). Countries where specific measures have been implemented to tackle BIA-ALCL account for 61% of the EU-28 population and actively reported 382 cases with an overall prevalence of 1:9121.

CONCLUSION

Countries where specific measures have been implemented show a higher prevalence of BIA-ALCL compared with the European mean, suggesting that these countries have improved the detection of the condition and reduced underreporting, which affects the numerator value. Other nations should adopt projections based on these measures to avoid underestimating how widespread BIA-ALCL is.

Use of the Subfascial Plane for Gender-affirming Breast Augmentation: A Case Series

Transgender women seeking gender-affirming breast augmentation often present with differences in preoperative chest measurements and contours in comparison with cisgender women. These include a more robust pectoralis muscle and limited glandular tissue, raising important considerations in determining the optimal anatomical plane for implantation. Abundant literature has described advantages and drawbacks of the available planes for breast augmentation in cisgender women. Certain drawbacks may be more pronounced for transgender women, given their distinct anatomy. The subfascial plane offers lower complication rates than the subglandular plane when using smooth implants, and avoids implant animation and displacement associated with the subpectoral plane. To our knowledge, existing studies have not yet addressed this discussion in the transfeminine population. The goal of this article is to highlight potential benefits of the subfascial plane for gender-affirming breast augmentation, utilizing a case series of 3 transfeminine patients, and to review the literature on surgical techniques and outcomes in this population.

Breast Implant-associated Anaplastic Large Cell Lymphoma - a Systematic Review with Pooled Analysis

The association of breast implants and anaplastic large cell lymphoma (BIA-ALCL) was first described in 1997. Such an association has aroused public health concerns on breast implant safety. A systematic review was carried out with a pooled analysis of data. In total, 674 non-duplicate articles were retrieved; 77 articles were included for data extraction; 395 patients were identified for analysis. The median age at the time of diagnosis was 52 years. Implant texture was described in 201 (50.9%) patients; all 201 patients had a textured implant. The median time from the last implant insertion to diagnosis was 7.5 years. Most patients presented with seroma (67.1%, n = 265), 20.5% of patients presented with breast mass (n = 81). Patients with a breast mass at presentation, lymphadenopathy and those without seroma had more disseminated disease (P < 0.001). 73.2% of patients (n = 289) opted for primary surgery, among which 68.6% (n = 271) received removal of the implant, 61% (n = 241) received capsulectomy and 2% (n = 8) received mastectomy. Of note, 5.3% (n = 21) had reinsertion of an implant after primary surgery. Non-surgical modalities included chemotherapy, radiotherapy and haematopoietic stem cell transplant. The median follow-up interval was 2 years (range 0-14.5 years). Seventeen patients (4.3%) had recurrence of BIA-ALCL and 195 patients (49.4%) did not. The median duration to first recurrence was 1 year (range 1-3 years). Long-term clinical outcome was not reported in 183 patients. BIA-ALCL is an indolent disease that presents with seroma after implant insertion. A high index of suspicion is needed for early diagnosis and treatment.

Breast Implant-Associated Anaplastic Large Cell Lymphoma Following Gender Reassignment Surgery: A Review of Presentation, Management, and Outcomes in the Transgender Patient Population

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare peripheral T-cell lymphoma with approximately 650-700 reported cases worldwide. The incidence, however, is increasing as more practitioners become aware of the diagnosis, and recent studies show that early diagnosis and treatment is critical to improve prognosis. There have been four cases of BIA-ALCL in total reported in the transgender population in the literature. These reported cases were reviewed in detail to determine presentation and management of BIA-ALCL in transgender patients compared to the larger population of BIA-ALCL patients. This review highlights BIA-ALCL in transgender women, a population that is often excluded from breast screening and follow-up. Transgender women may not routinely go through the same post-operative follow-up protocols as patients with breast implants for breast cancer reconstruction and can thus be at risk for delayed recognition and diagnosis. BIA-ALCL is a rare complication of breast implantation, and it is important to counsel all patients undergoing implant placement, including transgender women, on its risk.

Silicone Induced Granuloma of Breast Implant Capsule (SIGBIC) diagnosis: Breast Magnetic Resonance (BMR) sensitivity to detect silicone bleeding

Objective

To evaluate the sensitivity (S) of BMRI to detect silicone gel bleeding in a prospective observational study, including consecutive patients referred for BMRI scan.

Methods

From January 2017 to March 2018, we evaluated patients with breast implants referred for BMRI in a prospective observational study. For SIGBIC diagnosis, we adopted three new original imaging features: black drop signal; T2* hyper signal mass; and delayed contrast enhancement, considered as irrevocable signs to detect gel bleeding (GB). Histology confirmed the presence of a silicone corpuscle in breast implant capsular specimens. The accuracy of BMRI SIGBIC findings to predict GB was determined. We also compared SIGBIC diagnosis criteria to those features proposed by the BI-RADS léxicon, considered as equivocal findings.

Results

208 patients had SIGBIC diagnosis at BMRI, and the histology confirmed GB in all cases. There were no false-positive results. Compared to the BI-RADS equivocal findings (S = 0.74), SIGBIC criteria had better sensitivity for GB diagnosis.

Conclusion

SIGBIC diagnosis has high sensitivity to predict GB by the three irrevocable BMRI features described by the authors. We suppose GB is underdiagnosed in clinical practice by BI-RADS features.

A Rare Case of a Transgender Female With Breast Implant-Associated Anaplastic Large Cell Lymphoma Treated With Radiotherapy and a Review of the Literature

We are reporting a case of a 54-year-old transgender female with a history of breast augmentation with bilateral silicone implants. Seventeen years later, she presented with an enlarging right breast mass. Pathology confirmed breast implant–associated anaplastic large cell lymphoma (Ann Arbor Stage IIE, TNM Stage III BIA-ALCL). The patient underwent bilateral capsulectomy, sentinel lymph node biopsy with adjuvant CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy, and radiotherapy to the right chest, axilla, and supraclavicular lymph nodes. BIA-ALCL is a rare entity, especially in transgender females. We report this case and a review of the literature in this report.

The First Reported Case of Gluteal Implant-Associated Anaplastic Large Cell Lymphoma (ALCL)

Anaplastic large-cell lymphoma (ALCL) is a very rare but life-threatening complication that has largely been demonstrated to be associated with breast implants (BIA-ALCL). Patients are at risk of BIA-ALCL with the placement of breast implants for either cosmetic or reconstructive purposes, with the highest risks associated with textured breast implants. In the past decade, an increasing number of publications have focused on BIA-ALCL, but there has yet to be a reported case outside of the breast. Here, we describe a unique instance of gluteal implant-associated ALCL (GIA-ALCL) in a middle-aged woman. The patient received bilateral textured silicone gluteal implants only a year prior to her diagnosis of GIA-ALCL. The patient later presented to the Plastic and Reconstructive Surgery Department at our institution with ulceration at the site of her gluteal implants. Unfortunately, her condition deteriorated before explanation could be performed. Biopsy of a left lung mass demonstrated "hallmark" cells of ALCL ("horseshoe"-shaped nuclei). The diagnosis was verified by immunohistochemical testing that revealed expression of CD30, CD4, CD43, BCL6, Perforin, and Ki67 in a population of abnormal cells. The goals of this case report are thus to demonstrate that all patients undergoing implantation of textured silicone implants are at risk of developing ALCL and to provide evidence for the possible new diagnosis of GIA-ALCL.

Brentuximab vedotin as monotherapy for unresectable breast implant-associated anaplastic large cell lymphoma

BI-ALCL is a rare CD30+ T-cell malignancy, which is known to complicate textured breast implants. The CD30-targeting immunoconjugate, brentuximab vedotin, has been suggested for invasive BI-ALCL; however, its efficacy for unresectable BI-ALCL has not been demonstrated. We present a case of unresectable BI-ALCL, which was successfully treated with brentuximab vedotin.

Transcriptional analysis distinguishes breast implant-associated anaplastic large cell lymphoma from other peripheral T-cell lymphomas

Breast implant-associated anaplastic large cell lymphoma is a new provisional entity in the revised World Health Organization classification of lymphoid malignancies, the pathogenesis and cell of origin of which are still unknown. We performed gene expression profiling of microdissected breast implant-associated anaplastic large cell lymphoma samples and compared their transcriptional profiles with those previously obtained from normal T-cells and other peripheral T-cell lymphomas and validated expression of selected markers by immunohistochemistry. Our results indicate that most breast implant-associated anaplastic large cell lymphomas exhibit an activated CD4+ memory T-cell phenotype, which is associated with CD25 and FoxP3 expression. Gene ontology analyses revealed upregulation of genes involved in cell motility programs (e.g., CCR6, MET, HGF, CXCL14) in breast implant-associated anaplastic large cell lymphomas compared to normal CD4+ T-cells and upregulation of genes involved in myeloid cell differentiation (e.g., PPARg, JAK2, SPI-1, GAB2) and viral gene transcription (e.g., RPS10, RPL17, RPS29, RPL18A) compared to other types of peripheral T-cell lymphomas. Gene set enrichment analyses also revealed shared features between the molecular profiles of breast implant-associated anaplastic large cell lymphomas and other types of anaplastic large cell lymphomas, including downregulation of T-cell receptor signaling and STAT3 activation. Our findings provide novel insights into the biology of this rare disease and further evidence that breast implant-associated anaplastic large cell lymphoma represents a distinct peripheral T-cell lymphoma entity.

Anaplastic Large-Cell Lymphoma Associated with Breast Implants: A Case Report of a Transgender Female

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female. In June 2014, the patient developed a 5-cm tumorous mass in her left breast. Magnetic resonance imaging of the chest revealed a ruptured implant and a tumorous mass penetrating into the capsule and infiltrating the pectoral muscle. An R0 surgery was indicated-the implant, silicone gel and capsule were removed, and the tumorous mass was resected together with a part of the pectoral muscle. Histology revealed anaplastic large-cell lymphoma. The patient underwent standard staging procedures for lymphoma including a bone marrow trephine biopsy, which confirmed stage IE. The patient was treated with the standard chemotherapy for systemic ALCL-6 cycles of CHOP-21. The patient was tumor-free at the 2-year follow-up. BIA-ALCL has been reported mostly in women who received implants for either reconstructive or aesthetic augmentation. This is the third report of BIA-ALCL in a transgender person, the first in the Czech Republic. Level of Evidence V This journal requires that authors assign a level of evidence to each article.

Breast Erythema in a Patient With Breast Implant-Associated Anaplastic Large Cell Lymphoma: A Case Report Discussing Cutaneous Manifestations

LEVEL OF EVIDENCE 5

Breast Implant-Associated Anaplastic Large-Cell Lymphoma in a Transgender Woman

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare but serious complication in patients with breast implants, Patients are at risk of BIA-ALCL whether they receive breast implants for cosmetic reasons or for reconstructive purposes after surgery for breast cancer or prophylactic mastectomy. During the past decade, an increased number of reports have addressed BIA-ALCL. Herein, we describe BIA-ALCL in a transgender woman. The patient received breast implants as part of her gender transition and was diagnosed with BIA-ALCL 20 years later. The patient underwent several revisional operations in the 20 years after her primary breast surgery to treat unexplained pain with low-grade fever, severe capsular contracture (Baker grade III-IV), and several instances of implant rupture. In July 2016, the patient presented to our office with "late-onset" periprosthetic seroma 5 years after her last revisional breast surgery. She was diagnosed with BIA-ALCL without capsular invasion based on results of cytologic analysis of the periprosthetic seroma and histologic evaluation of the periprosthetic capsule. This diagnosis was verified further by results of immunohistochemical testing, which indicated expression of CD30 and T-cell markers in the periprosthetic seroma only. Our intentions with this case report are to demonstrate that all patients who undergo breast implantation, including transgender women, are at risk of BIA-ALCL and to highlight the importance of cytomorphologic and immunohistochemical screening of seroma fluid in patients with late-onset periprosthetic seroma.
