A Unique Case of Squamous Cell Carcinoma Presenting Within a Lesion of Granuloma Annulare.

Granuloma annulare (GA) is a common benign granulomatous inflammatory disorder of the dermis or subcutis with classic morphologic and histologic presentation. Common clinical subtypes of granuloma annulare include localized, generalized, subcutaneous, perforating, and patch types. A biopsy is critical in cases of granuloma annulare with atypical features. We present a case of a 58-year-old male who presented with an annular scaly erythematous plaque on the right dorsal hand. Shave biopsy demonstrated irregular nests of mildly atypical squamous epithelium present within the superficial dermis, with abundant histiocytes and multinucleated giant cells arranged in palisades peripherally. These findings were consistent with invasive well-differentiated squamous cell carcinoma (SCC) with surrounding granuloma annulare. This case highlights a unique presentation in which clinicopathologic correlation is critical prior to arriving at a correct diagnosis.

Study of a 532/1064 Fractional Picosecond Laser for Facial Rejuvenation.

BACKGROUND AND OBJECTIVES: Picosecond (ps) fractional lasers create small wounds, presumably by laser-induced optical breakdown. We studied a ps fractional laser in the treatment of wrinkles and mottled pigment. MATERIALS AND METHODS: This was a single center, prospective, open-label clinical trial. Patients with at least 2 facial areas, with visible wrinkles and dyschromia, were enrolled in the study and received 3 treatments at monthly intervals and appeared at 3 follow-up visits at 1, 3, and 6 months after treatment. The laser is an 800 ps fractional system with nominal 10 mm macrospot diameter. Both 532 nm and 1,064 nm wavelengths were applied in each subject. Wrinkle and pigmentation clearance were assessed by 2 blinded investigators using a 5-point clearance scale. Skin improvement was assessed by investigators using the 5-point Global Aesthetic Improvement (GAI) Scale based on before/after photographs for the following categories: (1) fine lines/wrinkles and (2) pigmentation. RESULTS: A total of 18 healthy subjects at a single site were enrolled. At least moderate pigmentation and fine line/wrinkles improvement were observed in 93% and 79% of patients at 1 month after the last treatment according to GAI, respectively. Pigment clearance approached a mean of approximately 40%. CONCLUSION: A ps 1,064/532 fractional laser achieves reduction in fine lines and pigment.

Patient Outcomes and Satisfaction After Mohs Micrographic Surgery in Patients With Nonmelanoma Skin Cancer.

BACKGROUND: Quality in medicine is increasingly being measured through patient-reported outcome measures. Given the rising incidence and costs for nonmelanoma skin cancer (NMSC) treatment, it is imperative to define quality measures specific to dermatologic surgery. OBJECTIVE: This study aims to evaluate patient-reported outcomes and satisfaction with Mohs micrographic surgery (MMS) together with patient and tumor factors to better define their use in developing treatment strategies and quality measures. METHODS AND MATERIALS: A prospective study was conducted among 226 patients undergoing MMS for treatment of NMSC. Patient demographics, quality of life, functional status, satisfaction, and prognostic factors were gathered. Postoperative outcomes were measured at 1 month and included patient-reported problems and provider-reported complications. Relationships between patient factors and outcomes were evaluated through statistical analysis. RESULTS: Average patient satisfaction in the domain of general satisfaction of the Patient Satisfaction Questionnaire-18 was 4.34 of 5. General patient satisfaction did not differ across age, final defect size, sex, or prognostic scores. At 1-month postoperatively, 97 percent of patients expressed willingness to undergo future MMS if indicated. CONCLUSION: Patients are generally satisfied with MMS for treatment of NMSC. Specific patient factors that may affect satisfaction include smoking status and anticoagulation use.

Misclassification of Aggressive Basal Cell Carcinoma Subtypes and Implications for Management.

BACKGROUND: Management of basal cell carcinoma (BCC) varies by histopathologic subtype; however, biopsies may inadequately characterize them as nonaggressive, risking potential suboptimal treatment. OBJECTIVE: To characterize the rate of undetected aggressive BCC subtypes by size, location, and histopathology type. MATERIALS AND METHODS: Retrospective cohort study of 928 BCCs treated with Mohs Micrographic Surgery (MMS) at a tertiary academic institution from 2015 to 2017, comparing patient and tumor characteristics and histopathologic subtype on biopsy versus Mohs. RESULTS: Among the 825 BCCs with known subtypes on biopsy, 68% (561/825) were classified as nonaggressive, 28% (159/561) of which were subsequently found to have aggressive subtypes on MMS. Aggressive features were more often underrepresented in biopsy samples taken from Area H compared with Area M/L (odd ratio [OR] 2.65, 95% confidence interval [CI] 1.73-4.08, p < .001) or those with nodular subtypes (OR 2.19, CI 1.08-4.45, p = .03). Of concern, these unsuspected aggressive BCCs required more Mohs stages for clearance (mean 2.37, SD 0.72, p < .001) compared with BCCs that remained nonaggressive on both biopsy and Mohs (mean 1.50, SD 0.75). CONCLUSION: Given the high percentage of BCCs with unsuspected aggressive subtypes, higher clinical suspicion for undiagnosed high-risk BCCs should be given to nodular BCCs and to BCCs on Area H.

Patient satisfaction and quality of care: a prospective study at outpatient dermatology clinics.

Patient satisfaction often is used as a proxy for quality of care, with physicians evaluated and reimbursed based on patient satisfaction scores. As a specialty, dermatology is lagging in quality improvement studies. To fill this gap, we conducted a prospective study of targeted interventions administered at outpatient dermatology clinics to determine if they resulted in statistically significant increases in patient satisfaction measures, particularly among Spanish-speaking patients. This study, along with the existing body of research, suggests the need for continued work to maximize patient satisfaction in dermatology.

Improving patient satisfaction in dermatology: a prospective study of an urban dermatology clinic.

Patient satisfaction has become an important measure of quality under the Patient Protection and Affordable Care Act. In this study, we assessed and analyzed patient satisfaction, nonattendance rates, and cycle times in an outpatient dermatology clinic. This study provides a snapshot of patient satisfaction in an urban dermatology clinic. Under the Patient Protection and Affordable Care Act, providers will be challenged to increase access to care and to validate quality of care through patient satisfaction.
