ABSTRACT: Early diagnosis and treatment of melanoma improve survival. New technologies are emerging that may augment the diagnosis, assessment, and management of melanoma but penetrance into everyday practice is low. In the current health care climate, greater emphasis will be placed on the incorporation of technology for clinically suspicious pigmented lesions to facilitate better, more cost-effective management.

3 Review The pathology of melanoma. 2012

Cockerell, Clay J. ·Department of Dermatology, UT Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390, USA. ccockerell@skincancer.com ·Dermatol Clin · Pubmed #22800551.

ABSTRACT: Although melanoma represents only 10% of all skin cancer diagnoses, it accounts for at least 65% of all skin cancer-related deaths. The number of new cutaneous melanoma cases projected during 2010 was 68,000-a 23% increase from the 2004 prediction of 55,100 cases. In 2015, the lifetime risk of developing melanoma is estimated to increase to 1 in 50. As the incidence of melanoma continues to rise, now more than ever, clinicians and histopathologists must have familiarity with the various clinical and pathologic features of cutaneous melanoma.

4 Review Malignant skin neoplasms. 2009

Ricotti, Carlos / Bouzari, Navid / Agadi, Amar / Cockerell, Clay J. ·Department of Dermatology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9069, USA. ·Med Clin North Am · Pubmed #19932329.

ABSTRACT: Skin cancers may be derived from any part of the skin, and the classification of all variants is extensive. Overall they are the most common cancers of the body, and include those that are highly mortal and those that are associated with an increased morbidity. In this review the most common skin cancers confronted by the clinician and their management are discussed. New associations are highlighted, as well as new information that can help the clinician to better understand the pathogenesis of many of these entities.

6 Review Biopsy of the pigmented lesion--when and how. 2008

Tran, Kien T / Wright, Natalie A / Cockerell, Clay J. ·Department of Dermatology, University of Texas Southwestern Medical Center, Dallas, Texas 75235, USA. ·J Am Acad Dermatol · Pubmed #18762353.

ABSTRACT: The biopsy lies at the heart of the management of the suspected melanocytic neoplasm. Dermatologists are the ideal physicians to examine patients with suspect melanocytic lesions and an understanding of when and how to perform a biopsy is vital. Various algorithms have been formulated to allow for facilitation of the clinical examination, including the ABCDE rule, the Glasgow 7-point checklist, and the "ugly duckling" sign. Along with this, dermoscopy can increase the sensitivity of diagnosis. Proper training regarding dermatoscopy is essential, especially with algorithms such as the Menzies method, the 7-point checklist, and pattern analysis. Digital photography and digital dermatoscopy allows for surveillance of suspect nevi or patients with multiple nevi. For neoplasms suspected of being melanoma, an excision for diagnosis with 1- to 3-mm borders is ideal, although a shave, punch, or other incisional biopsy can be performed in special circumstances. Finally, research has allowed for promising technologies including gene profiling of tape-stripped samples along with automated software analysis of digital dermatoscopic images.

ABSTRACT: BACKGROUND: Recently, a 23-gene signature was developed to produce a melanoma diagnostic score capable of differentiating malignant and benign melanocytic lesions. The primary objective of this study was to independently assess the ability of the gene signature to differentiate melanoma from benign nevi in clinically relevant lesions. METHODS: A set of 1400 melanocytic lesions was selected from samples prospectively submitted for gene expression testing at a clinical laboratory. Each sample was tested and subjected to an independent histopathologic evaluation by 3 experienced dermatopathologists. A primary diagnosis (benign or malignant) was assigned to each sample, and diagnostic concordance among the 3 dermatopathologists was required for inclusion in analyses. The sensitivity and specificity of the score in differentiating benign and malignant melanocytic lesions were calculated to assess the association between the score and the pathologic diagnosis. RESULTS: The gene expression signature differentiated benign nevi from malignant melanoma with a sensitivity of 91.5% and a specificity of 92.5%. CONCLUSIONS: These results reflect the performance of the gene signature in a diverse array of samples encountered in routine clinical practice.

9 Article The influence of a gene expression signature on the diagnosis and recommended treatment of melanocytic tumors by dermatopathologists. 2016

ABSTRACT: It is well documented that histopathologic examination is sometimes inadequate for accurate and reproducible diagnosis of certain melanocytic neoplasms. Recently, a 23-gene expression signature has been clinically validated as an adjunctive diagnostic test to differentiate benign nevi from malignant melanomas. This study aimed to quantify the impact of this test on diagnosis and treatment recommendations made by dermatopathologists.Diagnostically challenging melanocytic lesions encountered during routine dermatopathology practice were submitted for gene expression testing and received a melanoma diagnostic score (MDS). Submitting dermatopathologists completed a survey documenting pre-test diagnosis, level of diagnostic confidence, and recommendations for treatment. The survey was repeated after receiving the MDS. Changes between the pre- and post-test surveys were analyzed retrospectively.When the MDS was available as part of a comprehensive case evaluation in diagnostically challenging cases, definitive diagnoses were increased by 56.6% for cases that were initially indeterminate and changes in treatment recommendations occurred in 49.1% of cases. Treatment recommendations were changed to align with the test result in 76.6% of diagnostically challenging cases.The MDS impacts diagnosis and treatment recommendations by dermatopathologists confronted with diagnostically challenging melanocytic lesions. Increased data are needed in order to completely understand how use of the MDS will translate from dermatopathology to clinical practice.

10 Article Mitotic rate in cutaneous melanomas ≤1 mm in thickness: a prospective study. 2012

Litzner, Brandon R / Etufugh, Chukwuemeka N / Stepenaskie, Shelly / Hynan, Linda S / Cockerell, Clay J. ·Department of Dermatology, University of Texas-Southwestern Medical Center, Dallas, TX 75390-9069, USA. brandon.litzner@phhs.org ·Am J Dermatopathol · Pubmed #22878366.

ABSTRACT: The mitotic rate (MR) of malignant melanoma (MM) refers to the number of mitoses per square millimeter. Studies have suggested that it is an independent prognostic variable predicting survival in patients with MM, and it was recently included in the American Joint Committee on Cancer (AJCC) recommendations for diagnosis and treatment of MM. The AJCC melanoma staging committee recommends using the "hot-spot" approach to determine the MR, whereby it is reported as the maximum dermal mitotic figures identified in a 1-mm area of the melanoma. The AJCC has recommended that the MR be determined in all melanomas, irrespective of Breslow depth or other features. We aimed to quantify the MR in MM ≤1 mm in thickness and to identify statistical associations between the MR, Breslow depth, and Clark level. In addition, we hoped to identify practical issues in determining the MR via the hot-spot technique. We conducted a prospective study to determine the MR, Breslow depth, and Clark level in MM ≤1 mm in thickness. Seven melanomas were identified with epidermal mitoses only (7.4%). Sixteen melanomas had dermal mitoses (16.8%); of these, the majority (75.0%) contained only one mitotic figure. Seventy-nine melanomas had no dermal mitoses (83.2%). Seven lesions (7.4%) demonstrated multiple mitoses; 4 with ≥2 dermal mitoses/mm and 3 with multiple epidermal mitoses. We conclude that thin MM with >1 mitosis/mm is rare and discuss practical and theoretical issues with determining the MR using the hot-spot approach.
