A 79-year-old man was referred for evaluation of a recurrent neoplasm of the left scrotum.

Localized cutaneous squamous cell carcinoma (cSCC) has a favorable prognosis, unlike advanced disease, especially with clinical perineural invasion (PNI), which poses substantial management challenges due to aggressivity and higher recurrence, metastasis, and mortality risks. PNI, a high-risk staging feature, has worse outcomes, particularly when clinically evident rather than incidental. Clinical PNI (cPNI) is evident by clinical symptoms (such as pain, paresthesia, or motor deficits) or radiologic findings, whereas incidental PNI (iPNI) is identified only histologically without associated symptoms or radiologic evidence. PNI remains a novel area with varying practice patterns across institutions. Improving risk stratification and tailoring multidisciplinary approaches are critical for optimizing outcomes. Our review outlines clinical practice patterns at our institution, providing insights into managing cSCC with PNI, focusing on diagnosis, imaging, staging, and emerging immunotherapies. A structured search was conducted using the terms “perineural invasion,” “cutaneous squamous cell carcinoma,” and “immunotherapy.” cPNI has a poor prognosis and requires nuanced clinical decision-making. Surgery and radiation remain central to management. Adjuvant therapy offers substantial survival benefit in cSCC with PNI, with improved disease-free and overall survival compared with surgery alone, supporting its use in appropriately selected high-risk patients. Traditional systemic therapies, including cisplatin and cetuximab, remain foundational but have shown only moderate response rates and limited durability in advanced or neurotropic cSCC. In contrast, immunotherapy—now preferred for advanced or unresectable cases—has transformed management, with programmed cell death protein-1 (PD-1) inhibitors showing promising results (up to 69% response rate) and disease stabilization. Neoadjuvant immunotherapy may enable tumor downstaging, improve radiation planning, and reduce surgical morbidity. Imaging for squamous cell carcinoma (SCC) with PNI aids staging and surveillance, but symptoms remain key for detecting recurrence. Our multidisciplinary approach emphasizes personalized care. Larger trials are needed to define the optimal role and sequencing of immunotherapy in this high-risk patient population.

Abstract Background Dermatological health-related quality of life (HRQoL) among solid organ transplant recipients (SOTRs) may be adversely affected by various factors, including skin cancer. However, there has been limited assessment of dermatological HRQoL in SOTRs. This study aimed to evaluate the impact of skin cancer on quality of life (QoL) in SOTRs and to compare HRQoL measures between SOTRs with and without skin cancer. Methods This cross-sectional study was conducted at the Mayo Clinic Florida from June 2023 to March 2024. Adult patients who underwent solid organ transplantation between June 1995 and December 2023 were assessed using the Dermatology Life Quality Index (DLQI) and Skindex-29 questionnaires. For SOTRs with keratinocyte carcinoma (KC), the Basal and Squamous Cell Carcinoma Quality of Life (BaSQoL) questionnaire was also administered. Results A total of 150 adult SOTRs were included, with 82 having developed post-transplant skin cancer, including melanoma and keratinocyte carcinomas (KC). SOTRs with skin cancer were older at first transplant (Median: 61.8 vs. 57.3 years, P = 0.0073) and had a higher proportion of males (76.8% vs. 55.9%, P = 0.0086). Fitzpatrick skin type III-VI was less prevalent (8.5% vs. 38.2%, P < 0.0001). The frequency of SCC and BCC was 92.7% and 41.5%, respectively. DLQI scores were higher in SOTRs with skin cancer, however, the difference was not statistically significant (P ≥ 0.065). SOTRs with skin cancer had higher total Skindex-29 scores (P = 0.012) and “emotion” subscale scores (P = 0.0049), indicating a negative impact on QoL. BaSQoL scores showed a moderate negative effect on QoL, with a higher number of KCs correlating with lower QoL (P < 0.05). Female gender had higher DLQI total score (P = 0.0042) and BaSQoL diagnosis and treatment (P = 0.031). Conclusions: SOTRs with skin cancer exhibited lower overall QoL, with a greater number of skin cancers linked to more pronounced negative impacts on QoL across all assessment instruments. Female gender was also associated with lower QoL scores. Recognizing the potential for reduced QoL in SOTRs is essential for developing tailored management strategies to support this population.

BACKGROUND Flap repair provides unique advantages in facial reconstruction but still carries the potential for undesirable postoperative cosmetic changes. OBJECTIVE The aims of this study were to describe postoperative vascular outcomes of patients undergoing flap repairs after Mohs micrographic surgery on facial tumors and to assess associations of baseline characteristics with outcomes. MATERIALS AND METHODS In this study, 7 dermatologists and 1 physician assistant in dermatology assessed preoperative and postoperative photographs of 57 patients who underwent facial Mohs micrographic surgery, evaluating vascular and pigment outcomes and number of telangiectasias. RESULTS There was a significant difference in number of telangiectasias according to body location (p = .002), where the number of telangiectasias was highest for nose surgery. CONCLUSION These data suggest that nasal flap repairs are associated with increased postoperative vascular changes. This highlights an opportunity for improved preoperative patient counseling and possible early laser treatment after nasal Mohs micrographic surgery.
