RESUMO
BACKGROUND: Lentigo maligna (LM) can mimic benign, flat, pigmented lesions and can be challenging to diagnose. OBJECTIVE: To describe a new dermatoscopic feature termed "perifollicular linear projections (PLP)" as a diagnostic criterion for LM on the face. METHODS: Retrospective study on reflectance confocal microscopy and dermatoscopy images of flat facial pigmented lesions originating from 2 databases. PLP were defined as short, linear, pigmented projections emanating from hair follicles. Dermatoscopy readers were blinded to the final histopathologic diagnosis. RESULTS: From 83 consecutive LMs, 21/83 (25.3%) displayed "bulging of hair follicles" on reflectance confocal microscopy and 18 of these 21 (85.7%), displayed PLP on dermatoscopy. From a database of 2873 consecutively imaged and biopsied lesions, 252 flat-pigmented facial lesions were included. PLP was seen in 47/76 melanomas (61.8%), compared with 7/176 lesions (3.9%) with other diagnosis (P < .001). The sensitivity was 61.8% (95% CI, 49.9%-72.7%), specificity 96.0% (95% CI, 92.9%-98.4%). PLP was independently associated with LM diagnosis on multivariate analysis (OR 26.1 [95% CI, 9.6%-71.0]). LIMITATIONS: Retrospective study. CONCLUSION: PLP is a newly described dermatoscopic criterion that may add specificity and sensitivity to the early diagnosis of LM located on the face. We postulate that PLP constitutes an intermediary step in the LM progression model.

BACKGROUND: There is a paucity of literature describing family planning challenges faced by Mohs fellows. OBJECTIVE: To characterize perceptions about and experiences with family planning, fertility, lactation, and parental leave and identify ways to support parental health and family planning for Mohs fellows. MATERIALS AND METHODS: A voluntary, anonymous survey was distributed to Mohs surgeons who recently completed fellowship. RESULTS: In total, 116 Mohs surgeons completed the survey. Their mean age was 34.5 years old, and more were female ( n = 81, 69.8%) than male ( n = 35, 30.2%). Most had children before completion of their Mohs training ( n = 73, 62.9%). The most significant barrier to having children during fellowship was "loss of education or training time." Over 20% ( n = 23) of respondents or their partner had experienced infertility. Half of the 20 respondents ( n = 10) who breastfed or pumped did not have a convenient place to do so. CONCLUSION: This study elucidates trainee perceptions and gaps in parental support for Mohs fellowship trainees. In addition, barriers to implementing a universal family planning policy in Mohs surgery are discussed.

BACKGROUND: Lentigo maligna/lentigo maligna melanoma (LM/LMM) can present with subclinical extension that may be difficult to define preoperatively and lead to incomplete excision and potential recurrence. Preliminarily studies have used reflectance confocal microscopy (RCM) to assess LM/LMM margins. OBJECTIVE: To evaluate the correlation of LM/LMM subclinical extension defined by RCM compared with the gold standard histopathology. METHODS: Prospective study of LM/LMM patients referred for dermatologic surgery. RCM was performed at the clinically defined initial surgical margin followed by margin-controlled staged excision with paraffin-embedded tissue, and histopathology was correlated with RCM results. RESULTS: Seventy-two patients were included. Mean age was 66.8 years (standard deviation, 11.1; range, 38-89); 69.4% were men. Seventy of 72 lesions (97.2%) were located on the head and neck with mean largest clinical diameter of 1.3 cm (range, 0.3-5). Diagnostic accuracy for detection of residual melanoma in the tumor debulk (after biopsy) had a sensitivity of 96.7% and a specificity of 66.7% when compared with histopathology. RCM margin assessment revealed an overall agreement with final histopathology of 85.9% (κ = 0.71; P < .001). LIMITATIONS: No RCM imaging beyond initial planned margins was performed. CONCLUSION: RCM showed moderate to excellent overall agreement between RCM imaging of LM/LMM and histopathology of staged excision margins.

INTRODUCTION: Sweet syndrome (SS) is well-known to be associated with underlying hematologic malignancies. The incidence and qualities of SS among novel targeted therapies for acute myeloid leukemia (AML) have not yet been described. METHODS: Through retrospective review of 19432 patients diagnosed with acute/chronic leukemia or myelodysplastic syndromes/ myeloproliferative neoplasms (MDS+/-MPN) over 28 years, we calculated the incidence of SS in the setting of select hematologic malignancies and described the clinicopathologic characteristics of SS in patients with onset of SS after initiation of novel AML-targeted therapies. RESULTS: Overall incidence of SS was 0.36% (95% CI: 0.27% - 0.45%), which was significantly higher among patients with AML (50/5248, 0.94%; 95% CI: 0.71% - 1.25%). Nine AML patients were on 4 classes of novel targeted treatments - IDH1/2 inhibitor alone, FLT3 inhibitor, IDH2 and DOT1L inhibitor, and anti-CD33 therapy. In therapies inducing myeloid blast differentiation, SS occurred at later onset following treatment. CONCLUSIONS: In AML patients with fever and unusual skin lesions, physicians may consider SS earlier which may shorten time to diagnosis. Future assessments of SS among patients treated with novel therapies for AML and molecular studies of biopsies may help further explain this dermatologic adverse event with earlier diagnosis and management of neutrophilic dermatoses in these patients.
RESUMO
BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) of the ear is associated with poor outcomes. No studies have evaluated current staging system performance in this specific location. OBJECTIVE: Describe clinicopathologic characteristics and outcomes of ear cSCC and evaluate the performance of current staging systems. METHODS: Retrospective study including cases diagnosed and treated at a cancer center from January 2000 to December 2014. Demographic, clinical, and pathologic data were collected from clinical records. Biopsy slides were rereviewed and patients were staged according to the American Joint Committee on Cancer (AJCC) seventh, eighth, and Brigham Women's Hospital (BWH) staging. RESULTS: Of 125 patients, the mean age at diagnosis was 71.9 years (SD 12.5), with most men (89.6%, n = 112). Median follow-up was 22.3 months. Local recurrence and survival risk factors were similar to cSCC outside the ear. The Akaike's Information Criterion (AIC) estimates showed that the BWH system better predicted outcomes than the AJCC seventh, and the AJCC eighth, with AIC values of 189.9, 270.5, and 274.1, respectively. Limitations of the study include retrospective design, single center study, and no control group. CONCLUSION: Current staging systems perform well at stratifying risk in ear cSCC.

BACKGROUND: Risk-based thresholds to guide management are undefined in the treatment of primary cutaneous melanoma but are essential to advance the field from traditional stage-based treatment to more individualized care. METHODS: To estimate treatment risk thresholds, hypothetical clinical melanoma scenarios were developed and a stratified random sample was distributed to expert melanoma clinicians via an anonymous web-based survey. Scenarios provided a defined 5-year risk of recurrence and asked for recommendations regarding clinical follow-up, imaging, and adjuvant therapy. Marginal probability of response across the spectrum of 5-year recurrence risk was estimated. The risk at which 50% of respondents recommended a treatment was defined as the risk threshold. RESULTS: The overall response rate was 56% (89/159). Three separate multivariable models were constructed to estimate the recommendations for clinical follow-up more than twice/year, for surveillance cross-sectional imaging at least once/year, and for adjuvant therapy. A 36% 5-year risk of recurrence was identified as the threshold for recommending clinical follow-up more than twice/year. The thresholds for recommending cross-sectional imaging and adjuvant therapy were 30 and 59%, respectively. Thresholds varied with the age of the hypothetical patient: at younger ages they were constant but increased rapidly at ages 60 years and above. CONCLUSIONS: To our knowledge, these data provide the first estimates of clinically significant treatment thresholds for patients with cutaneous melanoma based on risk of recurrence. Future refinement and adoption of thresholds would permit assessment of the clinical utility of novel prognostic tools and represents an early step toward individualizing treatment recommendations.

BACKGROUND: Severe cutaneous adverse reactions (SCARs) are associated with high morbidity and mortality in patients with cancer. Early identification and treatment of SCARs may improve outcomes. OBJECTIVE: To identify biomarkers to predict outcomes in hospitalized patients with cancer who developed SCARs. METHODS: Retrospective review of 144 hospitalized patients with cancer with a morbilliform rash, recorded testing for serum cytokines (interleukin [IL]-6, IL-10, and tumor necrosis factor [TNF]-α) or elafin, and a dermatology consultation. Rashes were categorized as simple morbilliform rash without systemic involvement or complex morbilliform rash with systemic involvement. RESULTS: Fifty-four of 144 (37.5%) patients died during follow-up. Elevated levels of IL-6, IL-10, and TNF-α were associated with decreased survival. Overall survivals in patients with elevated levels of IL-6, IL-10, and TNF-α were 53.7%, 56.6%, 53.6%, respectively, compared with 85.7%, 82.5% and 83.6%, respectively, in those with lower levels. Patients with increased levels of both IL-6 and TNF-α had a nearly 6-fold increase in mortality (hazard ratio, 5.82) compared with patients with lower levels. LIMITATIONS: Retrospective design, limited sample size, and high-risk population. CONCLUSIONS: Hospitalized patients with cancer with rash and elevated IL-6 and TNF-α were nearly 6 times more likely to die over the course of follow-up. These biomarkers may serve as prognostic biomarkers and therapeutic targets for this high-risk population.

BACKGROUND: There are no well-defined clinical factors to predict the risk of occult invasion in melanoma of the lentigo maligna type (LM) before complete histopathologic analysis. OBJECTIVE: To evaluate whether clinical size was a predictor of invasion in LM and subclinical extension. METHODS: Consecutive cases of LM were recorded in a prospectively maintained database from 2006 to 2019. Patient and tumor data were recorded during initial evaluation. The LM clinical area was calculated in square millimeters (length × width). All patients were treated with staged excision. RESULTS: We included 600 patients. The mean age was 65.9 years (standard deviation, 12.3; range, 27-95 years); 62.8% (n = 377) were men. The mean LM clinical area was 128.32 mm2 for in situ lesions versus 200.14 mm for invasive lesions (P = .1). Based on quantile regression, the median margin required for complete removal increased with LM clinical area. LIMITATIONS: The study was performed in a tertiary cancer center with possible referral bias and more complex cases. CONCLUSIONS: LM can present with variable clinical size, which may correlate with subclinical extension; however, the presence of invasion is not well estimated by LM clinical area.

BACKGROUND: Novel solutions are needed for expediting margin assessment to guide basal cell carcinoma (BCC) surgeries. Ex vivo fluorescence confocal microscopy (FCM) is starting to be used in freshly excised surgical specimens to examine BCC margins in real time. Training and educational process are needed for this novel technology to be implemented into clinic. OBJECTIVE: To test a training and reading process, and measure diagnostic accuracy of clinicians with varying expertise level in reading ex vivo FCM images. METHODS: An international three-center study was designed for training and reading to assess BCC surgical margins and residual subtypes. Each center included a lead dermatologic/Mohs surgeon (clinical developer of FCM) and three additional readers (dermatologist, dermatopathologist, dermatologic/Mohs surgeon), who use confocal in clinical practice. Testing was conducted on 30 samples. RESULTS: Overall, the readers achieved 90% average sensitivity, 78% average specificity in detecting residual BCC margins, showing high and consistent diagnostic reading accuracy. Those with expertise in dermatologic surgery and dermatopathology showed the strongest potential for learning to assess FCM images. LIMITATIONS: Small dataset, variability in mosaic quality between centers. CONCLUSION: Suggested process is feasible and effective. This process is proposed for wider implementation to facilitate wider adoption of FCM to potentially expedite BCC margin assessment to guide surgery in real time.

BACKGROUND: The number needed to biopsy (NNB) ratio for melanoma diagnosis is calculated by dividing the total number of biopsies by the number of biopsied melanomas. It is the inverse of positive predictive value (PPV), which is calculated by dividing the number of biopsied melanomas by the total number of biopsies. NNB is increasingly used as a metric to compare the diagnostic accuracy of health care practitioners. OBJECTIVE: To investigate the association of NNB with the standard statistical measures of sensitivity and specificity. METHODS: We extracted published diagnostic accuracy data from 5 cross-sectional skin cancer reader studies (median [min-max] readers/study was 29 [8-511]). Because NNB is a ratio, we converted it to PPV. RESULTS: Four studies showed no association and 1 showed a negative association between PPV and sensitivity. All 5 studies showed a positive association between PPV and specificity. LIMITATIONS: Reader study data. CONCLUSIONS: An individual health care practitioner with a lower NNB is likely to have a higher specificity than one with a higher NNB, assuming they practice under similar conditions; no conclusions can be made about their relative sensitivities. We advocate for additional research to define quality metrics for melanoma detection and caution when interpreting NNB.

BACKGROUND: Initial biopsy of basal cell carcinoma (BCC) may fail to show aggressive histologic subtypes. Additionality, the clinical evaluation of BCC before surgery can miss subclinical extension. Reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) are emerging tools that can help in the presurgical evaluation of BCCs. OBJECTIVE: To assess the feasibility of a combined RCM-OCT imaging modality for presurgical evaluation of biopsy-proven BCCs for residual tumor, margin status, and depth. METHODS: Thirty-eight BCCs in 35 patients referred to a tertiary cancer center for Mohs micrographic surgery (MMS) were imaged with combined RCM-OCT. Images were correlated to MMS frozen sections. RESULTS: Thirty-eight BCCs were analyzed. The mean age of patients was 67.34 years (range, 36-84 years), and 20 patients were female (57.14%). Twenty four BCCs were located on the head (63.16%) , and the mean size was 8.58 mm (range, 3-30 mm). RCM-OCT showed an overall agreement of 91.1% with MMS frozen sections. A sensitivity of 82.6% (95% confidence interval [CI], 69%-92%), specificity of 93.8% (95% CI, 88%-97%), and receiver operating characteristic curve of 0.88 (95% CI, 0.82-0.94) was found. OCT depth was highly correlated with MMS depth (r2 = 0.9). LIMITATIONS: Small sample size and difficulty evaluating certain challenging anatomic sites. CONCLUSIONS: Combined RCM-OCT may emerge as a useful tool for presurgical evaluation of BCCs.

BACKGROUND: Computer vision has promise in image-based cutaneous melanoma diagnosis but clinical utility is uncertain. OBJECTIVE: To determine if computer algorithms from an international melanoma detection challenge can improve dermatologists' accuracy in diagnosing melanoma. METHODS: In this cross-sectional study, we used 150 dermoscopy images (50 melanomas, 50 nevi, 50 seborrheic keratoses) from the test dataset of a melanoma detection challenge, along with algorithm results from 23 teams. Eight dermatologists and 9 dermatology residents classified dermoscopic lesion images in an online reader study and provided their confidence level. RESULTS: The top-ranked computer algorithm had an area under the receiver operating characteristic curve of 0.87, which was higher than that of the dermatologists (0.74) and residents (0.66) (P < .001 for all comparisons). At the dermatologists' overall sensitivity in classification of 76.0%, the algorithm had a superior specificity (85.0% vs. 72.6%, P = .001). Imputation of computer algorithm classifications into dermatologist evaluations with low confidence ratings (26.6% of evaluations) increased dermatologist sensitivity from 76.0% to 80.8% and specificity from 72.6% to 72.8%. LIMITATIONS: Artificial study setting lacking the full spectrum of skin lesions as well as clinical metadata. CONCLUSION: Accumulating evidence suggests that deep neural networks can classify skin images of melanoma and its benign mimickers with high accuracy and potentially improve human performance.

BACKGROUND: Reflectance confocal microscopy (RCM) allows accurate, noninvasive, in vivo diagnosis for skin cancer. However, its impact on physicians' diagnostic confidence and management is unknown. OBJECTIVES: We sought to assess the physicians' diagnostic confidence and management before and after RCM of equivocal skin lesions. METHODS: Prospective, 2-center, observational study. During clinical practice, 7 dermatologists recorded their diagnostic confidence level (measured in a scale from 0 to 10), diagnosis, and management before and after RCM of clinically/dermoscopically equivocal lesions that raised concern for skin cancer. We also evaluated the diagnostic accuracy before and after RCM. RESULTS: We included 272 consecutive lesions from 226 individuals (mean age, 53.5 years). Diagnostic confidence increased from 6.2 to 8.1 after RCM (P < .001) when RCM confirmed or changed the diagnosis. Lesion management changed in 33.5% cases after RCM (to observation in 51 cases and to biopsy/excision in 31 cases). After RCM, the number needed to excise was 1.2. Sensitivity for malignancy before and after RCM was 78.2% and 85.1%, respectively. Specificity before and after RCM was 78.8% and 80%, respectively. LIMITATIONS: Small sample size, real-life environment, and different levels of expertise among RCM users. CONCLUSION: Physicians' diagnostic confidence and accuracy increased after RCM when evaluating equivocal tumors, frequently resulting in management changes while maintaining high diagnostic accuracy.

BACKGROUND: Postoperative concerns after Mohs micrographic surgery (MMS) are not well characterized. OBJECTIVE: To better define patient concerns and contributing characteristics in the immediate postoperative period after MMS. MATERIALS AND METHODS: A standardized telephone encounter template was implemented to better assess patient concerns in the 24-hour postoperative period. A review was then performed of patients undergoing MMS from October 2016 to July 2017 to assess for the most common patient concerns and association with clinical characteristics. RESULTS: We included 307 patients. Overall, 60.6% of patients reported a concern. Fifty-four percent of patients reported pain. Most pain was characterized as "a little" (67.7%). On univariate analysis, flap repairs, location on the upper extremities, and swelling were associated with higher mean postoperative pain. Tumor type was not associated with increased pain. On multivariate analyses, patients with larger defects and associated edema were statistically significantly associated with higher degrees of pain. CONCLUSION: Over half of patients experience postoperative concerns after MMS, most commonly pain. The immediate postoperative period may be an optimal time to identify patient concerns allowing for reassurance or early intervention when necessary.

BACKGROUND: Severe cutaneous adverse reactions (SCARs) are frequent in inpatient oncology. Early intervention might reduce morbidity, mortality, and hospitalization costs; however, current clinical and histologic features are unreliable SCAR predictors. There is a need to identify rational markers of SCARs that could lead to effective therapeutic interventions. OBJECTIVE: To characterize the clinical and serologic features of hospitalized patients with cancer who developed SCARs. METHODS: Retrospective review of 49 hospitalized cancer patients with a morbilliform rash, recorded testing for serum cytokines (interleukin [IL] 6, IL-10, and tumor necrosis factor [TNF] α) or elafin, and a prior dermatology consultation. Patients were categorized as having a simple morbilliform rash without systemic involvement or complex morbilliform rash with systemic involvement. RESULTS: Fifteen out of 49 patients (30.6%) were deceased at 6 months from time of dermatologic consultation. Elafin, IL-6, and TNF-α were significantly higher in patients who died compared with patients who were still alive at 6 months. IL-6 and IL-10 were significantly higher in patients with a drug-related complex rash. LIMITATIONS: Retrospective design, limited sample size, and high-risk patient population. CONCLUSION: In cancer patients with SCARs, elafin, IL-6, and TNF-α levels might predict a poor outcome. Agents directed against these targets might represent rational treatments for the prevention of fatal SCARs.

BACKGROUND: There is little evidence to guide surgical management of biopsies yielding the histologic descriptor atypical intraepidermal melanocytic proliferation (AIMP). OBJECTIVE: Determine frequency of and factors associated with melanoma and melanoma in-situ (MIS) diagnoses after excision of AIMP and evaluate margins used to completely excise AIMP. METHODS: Retrospective, cross-sectional study of 1127 biopsies reported as AIMP and subsequently excised within one academic institution. RESULTS: Melanoma (in situ, stage 1A) was diagnosed after excision in 8.2% (92/1127) of AIMP samples. Characteristics associated with melanoma/MIS diagnosis included age 60-79 years (odds ratio [OR] 8.1, 95% confidence interval [CI] 2.5-26.2), age ≥80 years (OR 7.2, 95% CI 1.7-31.5), head/neck location (OR 4.9, 95% CI 3.1-7.7), clinical lesion partially biopsied (OR 11.0, 95% CI 6.7-18.1), and lesion extending to deep biopsy margin (OR 15.1, 95% CI 1.7-136.0). Average ± standard deviation surgical margin used to excise AIMP lesions was 4.5 ± 1.8 mm. LIMITATIONS: Single-site, retrospective, observational study; interobserver variability across dermatopathologists. CONCLUSION: Dermatologists and pathologists can endeavor to avoid ambiguous melanocytic designations whenever possible through excisional biopsy technique, interdisciplinary communication, and ancillary studies. In the event of AIMP biopsy, physicians should consider the term a histologic description rather than a diagnosis, and, during surgical planning, use clinicopathologic correlation while bearing in mind factors that might predict true melanoma/MIS.

BACKGROUND: Biopsy specimens from patients with basal cell carcinoma (BCC) can present to surgery with no clinically residual tumor, complicating treatment decisions. OBJECTIVE: To evaluate reflectance confocal microscopy (RCM) for the assessment of residual BCC following biopsy. METHODS: Consecutive patients with biopsy-proven BCC and no clinical evidence of residual tumor who had been referred for Mohs micrographic surgery were included. Biopsy sites were imaged with a handheld RCM device. On the basis of RCM evaluation, cases were labeled RCM positive or RCM negative. Mohs micrographic surgery was performed in all cases; margins and 15-µm serial vertical sectioning were evaluated. RESULTS: A total of 61 patients were included (mean age, 61.7 years [standard deviation, 12.2 years]; range, 37-87 years); 60.7% were women. The mean lesion size was 5.1 mm (range, 3-12 mm); 73.8% of patients were positive on RCM, and 68.9% had residual BCC on histopathologic examination. The rates of RCM sensitivity, specificity, positive predictive value, and negative predictive value were 92.8%, 68.4%, 86.6%, and 81.2%, respectively. Three cases of BCC (high-risk, infiltrative, and basosquamous) were missed with use of RCM. When high-risk subtypes were excluded (n = 5), sensitivity and negative predictive value were both 100%. LIMITATIONS: RCM can miss deep-seated residual tumor. CONCLUSION: RCM is a valuable tool for the evaluation of residual BCC following biopsy, with the potential to reduce unnecessary surgical procedures.

BACKGROUND: Multiple BRCA1-associated protein 1 (BAP1)-inactivated melanocytic tumors (BIMTs) have been associated with a familial cancer syndrome involving germline mutations in BAP1. OBJECTIVES: We sought to describe the clinical and dermoscopic features of BIMTs. METHODS: This was a retrospective, multicenter, case-control study. Participating centers contributed clinical data, dermoscopic images, and histopathologic data of biopsy-proven BIMTs. We compared the dermoscopic features between BIMTs and control patients. RESULTS: The dataset consisted of 48 BIMTs from 31 patients (22 women; median age 37 years) and 80 control patients. Eleven patients had a BAP1 germline mutation. Clinically, most BIMTs presented as pink, dome-shaped papules (n = 24). Dermoscopically, we identified 5 patterns: structureless pink-to-tan with irregular eccentric dots/globules (n = 14, 29.8%); structureless pink-to-tan with peripheral vessels (n = 10, 21.3%); structureless pink-to-tan (n = 7, 14.9%); a network with raised, structureless, pink-to-tan areas (n = 7, 14.9%); and globular pattern (n = 4, 8.5%). The structureless with eccentric dots/globules pattern and network with raised structureless areas pattern were only identified in BIMT and were more common in patients with BAP1 germline mutations (P < .0001 and P = .001, respectively). LIMITATIONS: Limitations included our small sample size, retrospective design, the absence of germline genetic testing in all patients, and inclusion bias toward more atypical-looking BIMTs. CONCLUSIONS: Dome-shaped papules with pink-to-tan structureless areas and peripheral irregular dots/globules or network should raise the clinical suspicion for BIMT.
