Immune checkpoint inhibitors represent the newest treatment for stage IV melanoma. These agents are generally well tolerated, however severe immune-related adverse effects have been noted in a small, but clinically significant percentage of patients. Specifically, sarcoidosis is a known potential complication following anti-CTLA-4 therapy. We present 2 cases of pulmonary and cutaneous sarcoidosis developing in patients with stage IV melanoma. Both patients were treated with ipilimumab and anti-PD-1 therapy, and both experienced good oncologic responses to treatment; neither had evidence of preexisting sarcoidosis. Of note, both patients developed sarcoidosis only after undergoing immune checkpoint inhibitor therapy. In 1 patient, sarcoidosis developed after initiation of anti-PD-1 therapy, 3 months after the last dose of anti-CTLA-4 monotherapy, suggesting a synergistic immune dysmodulating effect of both checkpoint inhibitors. Ultimately, both patients' symptoms and radiologic findings resolved with corticosteroid treatment, and both patients have tolerated retreatment with PD-1 inhibitors. Sarcoidosis is a rare complication of immune checkpoint inhibitors and can manifest with severe pulmonary manifestations. However, sarcoidosis in this setting is responsive to corticosteroids and does not necessarily recur with retreatment. It is yet unclear whether the development of sarcoidosis in these patients represents unmasking of preexisting autoimmune tendencies or is a marker of oncologic response.

Background: Assessing medical students on core skills related to melanoma detection is challenging in the absence of a well-developed instrument., Objective: We sought to develop an objective structured clinical examination for the detection and evaluation of melanoma among medical students., Methods: This was a prospective cohort analysis of student and objective rater agreement on performance of clinical skills and assessment of differences in performance across 3 schools., Results: Kappa coefficients indicated excellent agreement for 3 of 5 core skills including commenting on the presence of the moulage (k = 0.87, 95% confidence interval 0.77-0.96), obtaining a history for the moulage (k = 0.84, 95% confidence interval 0.74-0.94), and making a clinical impression (k = 0.80, 95% confidence interval 0.68-0.92). There were no differences in performance across schools with respect to 3 of 5 core skills: commenting on the presence of the moulage (P = .15), initiating a history (P = .53), and managing the suspicious lesion (P value range .07-.17). Overall, 54.2% and 44.7% of students commented on the presence of the moulage and achieved maximum performance of core skills, respectively, with no difference in performance across schools., Limitations: Limitations include overall sample size of students and schools., Conclusion: The Skin Cancer Objective Structured Clinical Examination represents a potentially important instrument to measure students' performance on the optimal step-by-step evaluation of a melanoma., (Copyright © 2015 American Academy of Dermatology, Inc.

Importance: As medical school curricula become progressively integrated, a need exists to optimize education related to the skin cancer examination (SCE) for melanoma, a relevant competency gap that influences secondary prevention efforts., Objectives: To identify curricular factors associated with medical students' confidence, intent, and performance regarding the SCE., Design, Setting, and Participants: Survey-based cross-sectional study from the Integrated Skin Exam Consortium at accredited US medical schools among a volunteer sample of second-year students representing 8 geographically varied public and private institutions. Students were administered a questionnaire to assess characteristics, curricular exposures, and educational and practical experiences related to skin cancer, as well as knowledge of melanoma risk and a detection method., Main Outcomes and Measures: Primary outcomes were confidence in performing the SCE, intent to perform an integrated skin examination, and actual performance of the SCE., Results: Physical diagnosis session and clinical encounter were most predictive of confidence in performance of the SCE (odds ratios [ORs], 15.35 and 11.48, respectively). Other curricular factors associated with confidence included instruction time of at least 60 minutes on skin cancer (OR, 6.35), lecture on the SCE (OR, 7.54), knowledge of melanoma risk (OR, 3.71), and at least 1 opportunity to observe the SCE (OR, 2.70). Physical diagnosis session and at least 4 opportunities to observe the SCE were most predictive of intent to perform an integrated skin examination (ORs, 4.84 and 4.72, respectively). Other curricular factors associated with intent included knowledge of melanoma risk (OR, 1.83), clinical encounter (OR, 2.39), and at least 1 opportunity to observe the SCE (OR, 1.95). Clinical encounter, physical diagnosis session, and at least 1 opportunity to observe the SCE were most predictive of performance of the SCE (ORs, 21.67, 15.48, and 9.92, respectively). Other curricular factors associated with performance included instruction time of at least 60 minutes on skin cancer (OR, 2.42) and lecture on the SCE (OR, 5.04)., Conclusions and Relevance: To augment the practice of the SCE among medical students, course directors may design an integrated curriculum that includes at least 60 minutes of instruction related to melanoma and the SCE, a description of the integrated skin examination as part of the physical diagnosis course, and education on high-risk demographic groups and anatomic sites specific to men and women and on the ABCDEs of melanoma, and at least 1 opportunity to observe the SCE.

Background: Knowledge of the skin cancer examination (SCE) and its practice remain relevant competency gaps among medical students., Objective: We elaborate on a method of SCE known as the Integrated Skin Exam and discuss the development of an instructional film that illustrates its principles. We assess the tool's effect on knowledge, attitudes, and perceptions related to the SCE., Methods: Second-year students among 8 randomized schools viewed the film and completed pre-post questionnaires., Results: After viewing The Integrated Skin Exam film, students demonstrated improved melanoma knowledge, including identification of high-risk demographic groups (61% vs 42.9%, P < .001), high-risk anatomic sites in women (88.6% vs 46.5%, P < .001) and men (92.1% vs 34.8%, P < .001), and the ABCDEs of melanoma (98.4% vs 91.2%, P < .001). Students demonstrated increased confidence in the SCE (66.93% vs 16.40%, P < .001) and augmented intentions to practice it (99.05% vs 13.9%, P < .001). A greater proportion (70.4% vs 41.9%, P < .001) of students thought less than 3 minutes were required to integrate SCE into the routine examination., Limitations: Longitudinal impact of the film was not assessed., Conclusion: The Integrated Skin Exam film introduces an integrated approach to the SCE that addresses knowledge gaps, mitigates perceived barriers, and augments intention related to practice of the SCE., (Copyright © 2013 American Academy of Dermatology, Inc.

Background: Keratoacanthomas, as well as an actinic keratosis progressing to squamous cell cancer, have been reported in patients who were treated with sorafenib, a multikinase inhibitor known to suppress the actions of Raf kinase and vascular endothelial growth factor receptor., Observations: We describe a 70-year-old white woman with metastatic renal cell carcinoma who was treated with a combination of sorafenib and tipifarnib (a farnesyltransferase inhibitor). She had no history of skin cancer. However, within 3 months after starting this therapy, she developed 3 erythematous nodules on her legs. Pathologic examination showed deeply invasive, well-differentiated squamous cell carcinomas. The tumors were excised, and sorafenib-tipifarnib treatment was discontinued. No new lesions have developed to date., Conclusions: Targeted agents, such as sorafenib and tipifarnib, are increasingly being used in the management of visceral malignant neoplasms. A temporal relationship was observed between the initiation of the targeted treatments and the emergence of these cutaneous cancers. Further study of the mechanisms responsible for the rapid appearance of squamous cell cancers in this setting may provide insights into the pathogenesis of skin tumors.
