Late breast implant seroma may be the presentation of a breast implant-associated anaplastic large cell lymphoma (BI-ALCL), which claims for a prompt recognition. However, BI-ALCL diagnosis on fine-needle aspiration (FNA) might be challenging for pathologists lacking experience with peri-implant breast effusions. Sixty-seven late breast implant seromas collected by FNA from 50 patients were evaluated by Papanicolaou smear stain and immunocytochemistry on cell blocks. A diagnostic algorithm based on the cellular composition, cell morphology and percentage of CD30+ cells was developed. Histological evaluation of the corresponding peri-prosthetic capsules was also performed. Most of the effusions (91% of the samples) were classified as reactive and 9% as BI-ALCL. In the BI-ALCL cases, medium-to-large atypical cells expressing CD30 represented more than 70% of the cellularity, whereas in in the reactive effusions CD30+ elements were extremely rare (<5%) and consisted of non-atypical elements. The reactive effusions were categorized into three patterns: i) acute infiltrate with prominent neutrophilic component (33% of the samples); ii) mixed infiltrate characterized by a variable number of neutrophils, lymphocytes and macrophages (30% of the samples); iii) chronic infiltrate composed predominantly of T lymphocytes or macrophages with only sporadic granulocytes (37% of the samples). The inflammatory cytological patterns were consistent with the histology of the corresponding capsules. Our results indicate that cytological analysis of late breast implant effusions, supported by the knowledge of the heterogeneous cytomorphological spectrum of late seromas, is a valuable approach for the early recognition of BI-ALCL.
Complications of oral region fillers are similar in clinical presentation but differ in etiology, therefore necessitating different clinical approaches. Imaging techniques add useful information for treatment planning.
Aim of this study is to describe the use of high-frequency ultrasound to ascertain the site, quantity, and type of filler injected in the soft tissue of the face, with respect to reliability of the procedure and the analysis costs. Between December 2006 and August 2010, 80 subjects aged 25 to 65 years, who underwent facial filler augmentation, were submitted to high-frequency sonography. Of total, 42 patients (22 after temporary filler and 20 after permanent filler) were healthy and satisfied of the treatment, and 38 patients sought consultation for filler-related problems. The nature of the injected filler was known in 86.25% of the patients, whereas it was unknown in 13.75% of the patients. Besides 4 patients, previously treated with temporary products, in which no foreign material was detected, high-frequency sonography was able to identify and quantify the presence of filler in the soft tissue of 97% of patients. Moreover, it was possible to detect inflammatory reaction (that were often silent), granulomas, and recognize the presence of diverse fillers in the same area. Ultrasonography has proved to be a useful, inexpensive, noninvasive tool for the identification of the site, quantity, and often even nature of the filler injected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
