ABSTRACT
INTRODUCTION: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer in the White population. Unfortunately, the prognosis of advanced cSCC is poor, and management can be challenging. Until recently, the choice of systemic medications was limited, and those that were available had modest efficacy. Cemiplimab is an anti-programmed cell-death protein 1 inhibitor and the first immunotherapeutic agent approved for the treatment of metastatic or locally advanced cSCC. The purpose of this study was to evaluate the efficacy of cemiplimab when used as adjuvant or neoadjuvant therapy in patients treated at our institution. METHODS: A retrospective review of patients with locally advanced or metastatic cSCC who were treated with cemiplimab as adjuvant or neoadjuvant therapy at a single institution between February 2019 and November 2022 was performed. Response to treatment was objectively assessed based on Response Evaluation Criteria in Solid Tumors, version 1.1, criteria. The primary end point was objective response rate. Secondary endpoints included time to observed response, disease-control rate, progression-free survival, overall survival, and adverse effects of therapy. RESULTS: A total of 6 patients were identified with a median age of 79 years (range, 51-90 years). Four patients had locally advanced cSCC, and 2 had distant metastasis. Cemiplimab was used as adjuvant therapy in 3 patients and neoadjuvant therapy in 2 patients. There was 1 patient in which it was used for limb salvage, who would have otherwise required an amputation. Objective response rate, complete response, and partial response were 66% (4 of 6), 33% (2 of 6), and 33% (2 pf 6), respectively. Average time to observed response was 2.9 months. Disease-control rate was 83% (5 of 6), and average progression-free survival was 10 months. Toxicity was reported in 2 patients, both of which were grade 1 severity. CONCLUSIONS: Cemiplimab has established its utility in the treatment of advanced cSCC, demonstrating clinical efficacy while generally having a tolerable adverse effect profile. Our preliminary results suggest that cemiplimab has potential as an adjuvant or neoadjuvant therapy in combination with surgery for treatment of cSCC.

CASE: A 58-year-old woman with a history of systemic sarcoidosis, 2 years in remission, presented 6 years after bilateral carpal tunnel release with a 3-month history of nodularity, erythema, and tenderness to her bilateral incisions. Histopathology demonstrated noncaseating granulomas without evidence of foreign material or organisms, consistent with infiltrative scar sarcoidosis. Treatment included 4 intralesional corticosteroid injections over 5 months, with progressive resolution of symptoms and no evidence of systemic sarcoidosis reoccurrence. CONCLUSION: Sarcoidosis should be considered when presented with a cutaneous lesion in association with an incisional scar, either as primary presentation or as disease recurrence.

Acute care surgery has evolved to encompass the advanced management of complex nonhealing wounds. Biodebridement has the potential to improve the care of chronic wounds for acute care surgery patients, particularly for patients in the surgical intensive care unit (SICU) with hospital-acquired pressure injuries. A case report of biodebridement using larval maggot therapy in the SICU is presented to illustrate real-world application and progression in wound healing. A review of current research involving biodebridement was conducted. A septuagenarian gentleman sustained a fall resulting in cervical spine fractures with neurological deficits. The patient had a prolonged hospital course in the SICU, complicated by myocardial infarction, respiratory failure requiring tracheostomy, and development of a Stage IV sacral pressure ulcer. The wound base was sharply debrided several times and became refractory to conventional mechanical/chemical debridement techniques. The patient had a prohibitively high risk for the operating room but remained too sensate for further effective bedside debridement. Biodebridement was utilized to create a viable wound base, with improved appearance noted within 2 weeks. A review of the current literature shows biodebridement has numerous benefits in the management of chronic wounds. Biodebridement is a unique therapy that possesses great value for select patients in the SICU. In particular, patients who are too high risk for further operative intervention, but too sensate for ongoing bedside debridement and dressing changes, benefit significantly from this underutilized approach. Further research is needed to solidify the place of biodebridement in the surgical management of chronic nonhealing wounds.

In this article, we presented 2 cases of rare clinical presentation of 3-point lap-diagonal seat belt injuries and provided a brief overview of the spectrum of the associated deformity and morbidity. Both of our patients presented in a delayed fashion during the subacute period at 12 and 4 months, respectively, following their traumatic seat belt injuries, which improved with surgical intervention. Ideally, these injuries should be repaired during the subacute period once any life-threatening injuries have been addressed, because seat belt-restraint injuries may otherwise lead to chronic pain, functional loss, and physical deformity.
ABSTRACT
BACKGROUND: In some patients, papillary thyroid carcinoma (PTC) lymph-node metastases are noted to be black (dark) in color at the time of surgical removal. The goal of this project was to determine histological, genetic, and clinical features that are associated with regional black PTC metastasis. METHODS: Fifteen patients with black PTC metastases (black-PTC) were compared to a control cohort of 15 patients with nonblack PTC metastasis (nonblack PTC). Each sample was evaluated for the histological characteristics, BRAF V600E mutational status, and associated patient clinical data. RESULTS: The degree of cystic degeneration (80% vs. 27%, p=0.004), percent hemosiderin deposition (20% vs. 6%, p=0.001), and presence of classical variant (100% vs. 67%, p=0.018) were significantly greater in black PTC than nonblack PTC (α=0.05). Other results were not significantly different. CONCLUSION: This study demonstrates that black compared to nonblack metastases have a greater degree of cystic degeneration and hemosiderin deposition leading to discoloration, and a trend toward an increased incidence in BRAF V600E mutations. This study is the first of its kind to describe the clinical, pathological, and genetic features associated with black PTC lymph-node metastasis.
