Immune status does not independently influence cutaneous squamous cell carcinoma metastasis and death when stratified by tumor stage: A dual-center retrospective cohort analysis of primary N0 disease.

BACKGROUND: Although immunocompromised patients have a higher risk of developing cutaneous squamous cell carcinomas, it is unknown whether immune status is an independent risk factor for poor outcomes. OBJECTIVE: To compare cutaneous squamous cell carcinoma outcomes in immunocompromised and immunocompetent patients when controlling for T-stage. METHODS: We performed a retrospective cohort study at 2 tertiary care centers, examining 989 primary tumors from 814 immunocompromised patients (solid organ transplant: 259 [31.7%], chronic lymphocytic leukemia: 113 [13.9%]) and 6608 tumors from 4198 immunocompetent patients. Our primary outcome was the composite of disease-specific death or tumor metastasis ("poor outcomes"). RESULTS: Immunocompromised patients had 50% more high T-stage tumors (ie, Brigham and Women's Hospital stage T2b and T3), than immunocompetent patients (3.3% vs 4.9%, respectively; P < .001). Significant predictors of poor outcomes included tumor stage (sub hazards ratio [SHR], 14.8 for high T-stage tumors; 95% confidence interval [CI], 8.0-27.6; P < .001) and male sex (SHR, 2.3; 95% CI, 1.4-3.8; P = .002). Immune status was not a significant predictor (SHR, 1.04; 95% CI, 0.69-1.6; P = .85). LIMITATIONS: This study is retrospective. CONCLUSION: Although immunocompromised patients had 50% more high T-stage tumors than immunocompetent patients, immunocompromised patients had a similar chance of metastasis and disease-specific death when adjusting for T-stage in our cohort of primary tumors.

Adherence to the National Comprehensive Cancer Network Criteria of Complete Circumferential Peripheral and Deep Margin Assessment in Treatment of High-Risk Basal and Squamous Cell Carcinoma.

BACKGROUND: The National Comprehensive Cancer Network (NCCN) has established guidelines for the treatment of keratinocyte carcinomas (KCs). Complete circumferential peripheral and deep margin assessment (CCPDMA) is recommended for "high-risk" tumors that cannot be closed primarily. If flap or grafts are needed and CCPDMA was not used, it is recommended that reconstruction be delayed until achieving clear margins. OBJECTIVE: To measure provider utilization rates of the NCCN guidelines for high-risk KCs and assess barriers that are limiting adherence. MATERIALS AND METHODS: A ten-item questionnaire was distributed to NCCN nonmelanoma skin cancer panel members and physicians participating in KC treatment at academic institutions. RESULTS: Response rate was 49% (57/116). Responses were categorized by practice area: Mohs surgery, pathology, and other specialties: General Dermatology, Otolaryngology, Plastic Surgery, Surgical Oncology, Radiation Oncology, and Oral and Maxillofacial Surgery. Mohs surgeons were most likely to use CCPDMA for tumors meeting NCCN criteria with 14/15 using this technique in a majority of their cases, versus 2/6 pathologists and 10/16 specialists from other fields. Reasons cited for not using CCPDMA included deference to pathologists to determine the appropriate method for margin assessment and logistical difficulty. CONCLUSION: Further efforts are needed to increase adherence to NCCN's guidelines regarding CCPDMA in KCs.

A 78-Year-Old Female with a Diffuse Pruritic Rash and Palmoplantar Desquamation.

Mycosis fungoides, the most common cutaneous T-cell lymphoma, is known to exhibit varied clinical presentations and mimic many other dermatoses. This morphological heterogeneity can often lead to initial misdiagnoses resulting in significant delays from symptom onset to diagnosis. We report a case of mycosis fungoides imitating clinical and histopathological features of erythema annulare centrifugum.

An open label pilot study of supraerythemogenic excimer laser in combination with clobetasol spray and calcitriol ointment for the treatment of generalized plaque psoriasis.

A common therapeutic modality for psoriasis includes the combination of phototherapy with topical treatments. The recent development of targeted phototherapy with the excimer laser and spray formulations for topical treatments has increased the efficacy and convenience of these combinational therapies. Herein, we aim to assess the efficacy of a novel combination of therapies using the 308 nm excimer laser, clobetasol propionate spray and calcitriol ointment for the treatment of moderate to severe generalized psoriasis. In this 12-week study, patients with moderate to severe psoriasis received twice weekly treatments with a 308-nm excimer laser combined with clobetasol proprionate twice daily for a month followed by calcitriol ointment twice daily for the next month. Of the 30 patients enrolled, 83% of patients (25/30) achieved PASI-75 [65-94%, 95% confidence interval (CI)] at week 12. For PGA, there was an estimated decrease of 3.6 points (3.1-4.1, 95% CI, p < 0.0005) by week 12. In conclusion, the combination of excimer laser with alternating clobetasol and calcitriol application has shown to be a promising combination of therapies for the treatment of moderate to severe generalized psoriasis. Further evaluation may be conducted with a larger study inclusive of control groups and head-to-head comparisons against topical steroid and UVB therapy as monotherapies.

The role of the dermatologist in detecting elder abuse and neglect.

The National Research Council of the National Academies defines elder mistreatment as: (1) intentional actions that cause harm or create serious risk of harm (whether or not harm is intended) to a vulnerable elder by a caregiver or other person who stands in a trust relationship to the elder; or (2) failure by a caregiver to satisfy the elder's basic needs or to protect the elder from harm. Estimates of the prevalence of elder abuse have ranged from 2.2% to 18.4%. Dermatologists are uniquely positioned to identify and manage suspected cases of elder abuse given their expertise in distinguishing skin lesions of abuse from organic medical disease and their patient populations with strong elderly representation. This article discusses aspects of both the screening and management of elder abuse with particular relevance to dermatologists. Like physicians across medical specialties, dermatologists must be familiar with those aspects of elder abuse in screening, diagnosis, management, and reporting that are unique to their field and to those aspects that are applicable to all health care providers.
