Chronic lymphocytic leukemia and the skin: implications for the dermatologist

Fried, Lauren J; Criscito, Maressa C; Stevenson, Mary L; Pomeranz, Miriam K
B-cell chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the United States, and its diagnosis can have many dermatologic implications. For one, the cutaneous manifestations of CLL include several entities, most notably leukemia cutis, eosinophilic dermatosis of hematologic malignancy, and a heightened risk of skin infections. Additionally, CLL patients are at an increased risk of secondary malignancies, most commonly of the skin. Furthermore, a number of commonly utilized treatments for CLL have cutaneous implications which should be considered in the interdisciplinary management of CLL patients. In this review, we will provide an update on the diverse cutaneous manifestations of CLL and CLL-directed therapies in order to help guide dermatologic management of this increasingly prevalent patient population.

Deliberate practice-based surgical curriculum leads to enhanced technical proficiency among dermatology residents

Criscito, Maressa C; Wilken, Reason; Stevenson, Mary L; Carucci, John A
Deliberate practice-based medical education has demonstrated superiority in trainee acquisition and maintenance of skills in several surgical subspecialties. In an effort to highlight the impact of a deliberate practice-based surgical curriculum on the technical proficiency of dermatology residents, a prospective cohort study including first- and second-year dermatology residents was performed. A total of 87.5% (7 of 8) first-year dermatology residents completed three hands-on simulations at 6-week intervals. Additionally, six of eight (75.0%) second-year dermatology residents at the same institution were evaluated at a single point-in-time session without accessing the surgical curriculum prior. A 5-point global rating scale (GRS) was used to assess resident performance on six core surgical techniques. Nonparametric ANOVA statistical methods using the Kruskal-Wallis test was performed. The residents' overall GRS increased from a median of 1-2.75 after completion of the curriculum (p < 0.01). There was a significant improvement in the median scores of each tested surgical technique. The first-year residents had a greater overall GRS after completion of the curriculum compared to the second-year residents (median of 2.13 versus 1.88, p < 0.001). Limitations include the small sample size and lack of a synchronized control group. Our study highlights the use of deliberate practice-based strategies as an effective modality in teaching surgical skills to dermatology residents.

Skin Cancer in People of Color: A Systematic Review

Zakhem, George A; Pulavarty, Akshay N; Lester, Jenna C; Stevenson, Mary L
BACKGROUND:People of African, Asian, Hispanic or Latino, Pacific Islander, and Native Indian descent are considered people of color by the Skin of Color Society (SOCS). OBJECTIVES/OBJECTIVE:In this study, we assess incidence, risk factors, clinical characteristics, histopathology, treatment, and survival for skin malignancies in people of color as defined by the SOCS, by systematically reviewing the literature. METHODS:An electronic literature search of the PubMed, EMBASE, and MEDLINE databases was performed. Articles published from 1 January 1990 through 12 December 2020 were included in the search. RESULTS:We identified 2666 publications potentially meeting the study criteria. Titles and abstracts of these studies were reviewed and 2353 were excluded. The full text of 313 articles were evaluated and 251 were included in this review. CONCLUSION/CONCLUSIONS:Differences in incidence, patterns, treatment, and survival exist among people of color for cutaneous malignancies. Further research and initiatives are needed to account for and mitigate these differences.

Deep learning automated pathology in ex vivo microscopy

Combalia, Marc; Garcia, Sergio; Malvehy, Josep; Puig, Susana; Mülberger, Alba Guembe; Browning, James; Garcet, Sandra; Krueger, James G; Lish, Samantha R; Lax, Rivka; Ren, Jeannie; Stevenson, Mary; Doudican, Nicole; Carucci, John A; Jain, Manu; White, Kevin; Rakos, Jaroslav; Gareau, Daniel S
Standard histopathology is currently the gold standard for assessment of margin status in Mohs surgical removal of skin cancer. Ex vivo confocal microscopy (XVM) is potentially faster, less costly and inherently 3D/digital compared to standard histopathology. Despite these advantages, XVM use is not widespread due, in part, to the need for pathologists to retrain to interpret XVM images. We developed artificial intelligence (AI)-driven XVM pathology by implementing algorithms that render intuitive XVM pathology images identical to standard histopathology and produce automated tumor positivity maps. XVM images have fluorescence labeling of cellular and nuclear biology on the background of endogenous (unstained) reflectance contrast as a grounding counter-contrast. XVM images of 26 surgical excision specimens discarded after Mohs micrographic surgery were used to develop an XVM data pipeline with 4 stages: flattening, colorizing, enhancement and automated diagnosis. The first two stages were novel, deterministic image processing algorithms, and the second two were AI algorithms. Diagnostic sensitivity and specificity were calculated for basal cell carcinoma detection as proof of principal for the XVM image processing pipeline. The resulting diagnostic readouts mimicked the appearance of histopathology and found tumor positivity that required first collapsing the confocal stack to a 2D image optimized for cellular fluorescence contrast, then a dark field-to-bright field colorizing transformation, then either an AI image transformation for visual inspection or an AI diagnostic binary image segmentation of tumor obtaining a diagnostic sensitivity and specificity of 88% and 91% respectively. These results show that video-assisted micrographic XVM pathology could feasibly aid margin status determination in micrographic surgery of skin cancer.

Skin Cancers and Lung Transplant

Wilken, Reason; Carucci, John; Stevenson, Mary L
It is well known that solid-organ transplant recipients (SOTRs) have a 65- to 100-fold increase in the risk of developing skin cancer, namely, nonmelanoma skin cancers (NMSCs) such as cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC). In addition, these patients are also at increased risk for development of melanoma as well as other less common cutaneous malignancies (Merkel's cell carcinoma, Kaposi's sarcoma). SOTRs with NMSC (namely cSCC) are also at significantly increased risk of poor clinical outcomes including local recurrence, nodal and distant metastasis, and disease-specific death relative to patients who are not immunosuppressed. Increased surveillance and monitoring in patients at risk of aggressive disease and poor outcomes who are on immunosuppression is essential in patients with lung transplants given the high degree of immunosuppression. Increased awareness of risks, treatments, and management allows for improved outcomes in these patients. This article will provide an overview of the risk factors for the development of cutaneous malignancies in organ transplant recipients as well as a detailed discussion of various immunosuppressant and prophylactic medications used in this patient population that contribute to the risk of developing cutaneous malignancies, with an emphasis on NMSC (cSCC and BCC) in lung transplant recipients. Finally, this article includes a discussion on the clinical and dermatologic management of this high-risk immunosuppressed population including a review of topical and systemic agents for field therapy of actinic damage and chemoprevention of keratinocyte carcinomas. In addition, indications for additional treatment and preventive measures such as adjuvant radiation treatment after surgical management of cutaneous malignancies and potential modification of immunosuppressive medication regimens are discussed.
