Fibrous tumor of the breast is an underappreciated, distinctive, benign, nonrecurrent lesion of the breast. The cytological features of this condition are not well characterized. We present a case report of a 30-year-old female presenting with a hard mass in her right breast. Fine needle aspiration showed smears of low cellularity showing a few clusters and sheets of mostly uniform benign epithelial cells, some of which were lined by myoepithelial cells. Scattered bipolar bare nuclei or stromal fragments were not seen. Excision with subsequent histopathological examination revealed a well-circumscribed, heavily collagenous tumor with atrophy and replacement of the epithelial and ductal elements of the breast, and diagnosed as fibrous tumor. Being nonrecurrent, it is important to distinguish this lesion from fibromatosis of the breast.

Introduction: Percutaneous needle fasciotomy (PNF) is a non-invasive treatment option for finger flexion contractures caused by Dupuytren's disease. Variations in PNF techniques include the use of corticosteroid injection. In the presented randomised controlled trial, we compare the efficacy of PNF +/- corticosteroid injection in terms of reducing the recurrence rate.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.

Breast desmoid tumour is a rare type of benign breast disease that presents like malignancy. Current guidelines are based on limited evidence derived from case reports and small case series and recommend resection with microscopically-negative margin (R0). There is a high risk of recurrence despite negative surgical margins.

University of Alabama at Birmingham, Birmingham, Alabama, USA.
Background: Benign bone lesions are a common incidental finding in athletes during workup for musculoskeletal complaints, and athletes are frequently advised to halt participation in contact sports. There are no current guidelines to assist clinicians in referring patients with these lesions to a subspecialist or in advising athletes on the safety of returning to sport.
Purpose: To assist sports medicine physicians in appropriate referral for patients with benign bone lesions through presentation of a literature review and the case of an adolescent athlete with a benign bone lesion in a location with a significant fracture risk.
