Superficial subcutaneous lipomas are common benign tumors of the subcutaneous adipose tissue. Removal of superficial subcutaneous lipomas is achieved with simple surgical excision for the purposes of improved cosmesis, removing painful lipomas, or for the removal of a lipoma affecting function through mass effect. As research in localized fat reduction has improved, therapies successful in this domain have been applied to the management of lipomas as a surgical alternative. In this review article, the authors review the basic science of injection therapies used in the management of lipomas as well as their potential efficacy and limitations.

Expanding the Range of Epithelial Marker and SMA Staining of Superficial CD34+ Fibroblastic Tumors: A Case Report and Review of the Literature.
Am J Dermatopathol

Departments of Dermatology and Pathology, University of California, Irvine, CA.
Superficial CD34+ fibroblastic tumor (SCD34FT) is a relatively recently described borderline mesenchymal neoplasm. Owing to a relative lack of specificity in clinical presentation, radiopathologic findings, and immunohistochemical staining, the diagnoses of SCD34FT can be challenging. In this study, we present a case of a 55-year-old woman with an indolent painless nodule on the right shin.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Department of Neurosciences, Institute of Human Anatomy, University of Padova, 35121 Padova, Italy.
Background: Lymphedema represents a frequent cause of disability for patients undergoing oncological treatments and, being a chronic, non-reversible pathology, requires targeted and continuous rehabilitation treatments. To date, the studies available on the use of ultrasound in patients with lymphedema mainly report descriptive data; therefore, with this study, we wanted to describe in a more objective way the typical ultrasound alterations found in these patients, measuring the thickness of the different superficial structures, and defining subcutis echogenicity.
Methods: 14 patients affected by secondary lymphedema of the upper limbs were enrolled in this cross-sectional observational study (12 had breast cancer and 2 with melanoma as their primary diagnosis).

Phaeohyphomycosis is a fungal infection caused by dematiaceous fungi that presents as a superficial, cutaneous, subcutaneous, or systemic infection. Subcutaneous phaeohyphomycosis is the most common manifestation and presents as a subcutaneous nodule or cystic lesions and abscesses. It usually results from traumatic implantation of the saprophytic fungus from soil and vegetative matter; therefore, the commonest sites of infection are the extremities.

Department of Dermatology, Erasmus Universiteit Rotterdam, Rotterdam, Netherlands.
Background: Midfacial aging involves skeletal changes, muscle weakening, and fat redistribution, resulting in volume loss, skin sagging, and deepened nasolabial folds. High-Intensity Facial Electrical Stimulation (HIFES) combined with Radiofrequency (RF) is a novel non-invasive method to address these changes by enhancing muscle mass and remodeling subcutaneous tissue.
Objectives: To assess the efficacy of HIFES and Synchronized RF in improving midfacial aesthetics, specifically muscle thickness, skin displacement, and facial volume.
