Abstract: This document provides methods and materials for identifying metastatic malignant skin lesions (e.g., malignant pigmented skin lesions). For example, methods and materials for using quantitative PCR results and correction protocols to reduce the impact of basal keratinocyte contamination on the analysis of test sample results to identify metastatic malignant skin lesions are provided. This document also provides methods and materials for treating skin cancer. For example, methods and materials for identifying a mammal (e.g., a human) having a pre-metastatic skin lesion (e.g., pre-metastatic melanoma) and treating that mammal with pentamidine (4,4?-[pentane-1,5-diylbis(oxy)]dibenzenecarboximidamide) are provided.

Abstract: The disclosure provides gene signatures of classifying an individual afflicted with cutaneous melanoma. The “SLN gene signatures” provided herein classify an individual based on prognosis and/or classify an individual as having a metastasis-positive or -negative sentinel lymph node (SLN). The “N-SLN gene signatures” provided herein classify an individual as having a metastasis-positive or -negative non-sentinel lymph node (N-SLN).

Abstract: This document provides methods and materials for staging and treating skin cancer (e.g., metastatic malignant pigmented skin lesions). For example, methods and materials for using an ITLP expression profile and/or models including an ITLP expression profile to stage skin cancer and/or determine treatment options for skin cancer patients are provided.

Abstract: This document provides methods and materials involved in identifying and/or treating acute GVHD. For example, methods and materials for detecting elevated levels of nucleic acid expression (e.g., an elevated level of MxA nucleic acid expression or an elevated level of expression of a nucleic acid that encodes a polypeptide listed in Table 2, Table 3, and/or Table 4) in a skin sample to identify a mammal as having acute GVHD are provided.

Abstract: This document provides methods and materials for reducing arthrofibrosis at a wound site and/or reducing scar formation and adhesion after tendon injury. For example, provided herein are methods and materials for administering pentamidine to reduce arthrofibrosis and/or scarring and adhesion formation associated with a wound or tendon injury.

Abstract: This document provides methods and materials for reducing scar formation (e.g., scar formation during wound healing) and/or for reducing keloid formation (e.g., keloid formation that occurs during wound healing or keloid formation that does not occur during wound healing). For example, methods and materials for topically administering pentamidine to reduce scar formation and/or to reduce keloid formation are provided.
