Background Solitary pink lesions often manifest nondescript clinical and dermatoscopic primary morphologic features. The differential diagnosis for pink lesions tends, therefore, to be broad, ranging ...from inflammatory processes to malignancy. In vivo reflectance confocal microscopy (RCM) may help in the evaluation of pink lesions. Objective We sought to demonstrate the use of RCM as an adjunct to the bedside diagnosis of pink lesions. Methods We describe a series of patients with clinically and dermatoscopically equivocal pink lesions for which RCM examination allowed for a rapid and accurate diagnosis. All lesions were excised for histopathologic evaluation. Integrating the findings in the case series with a literature review, we present RCM diagnostic criteria for pink lesions. Results Lesions included basal cell carcinoma, squamous cell carcinoma, amelanotic melanoma, and inflamed seborrheic keratosis. RCM shows distinctive findings for each diagnostic entity when stratified by anatomic level into suprabasal epidermis, dermoepidermal junction, and papillary dermis. In the cases presented RCM allowed for a rapid and accurate noninvasive diagnosis. Limitations The study is descriptive and does not test accuracy of RCM criteria in a prospective series of pink lesions. Conclusion RCM may add useful diagnostic features to the clinical evaluation of solitary pink lesions.
Seborrheic keratosis is a common skin lesion that can usually be recognized either clinically or dermoscopically. However, melanomas mimicking seborrheic keratoses, as well as melanomas arising in ...association with seborrheic keratoses, have been described. We report the case of a patient with a lesion that initially revealed “classic” dermoscopic features of a seborrheic keratosis. However, during follow-up, changes in color developed within the center of the lesion that led the clinician to the correct diagnosis of melanoma. Upon retrospective evaluation of the baseline image of the lesion; the clinician was now able to “see” that which his brain could not appreciate on initial examination and to realize that the lesion had subtle features suspect for melanoma. This case represents a diagnostic pitfall due to errors in perception. Dermatologists should be cognizant of “errors in perception”; we suggest that a final dermoscopic judgment of a seborrheic keratosis be rendered by combining the gestalt diagnosis of the overall pattern, with deliberate dermoscopic analysis of all quadrants of the lesion.
As the relationship between tobacco smoking and acne remains unclear, we examined the relationship between cigarette smoking and severe acne in a large cohort of young men. Trained nurses interviewed ...subjects upon discharge from compulsory military service, regarding family history, habits, and tobacco smoking habits. Data was correlated with severe acne status, as diagnosed and coded by board-certified dermatologists. In total, 27,083 male subjects participated in the study from 1983 to 2003, of which 237 (0.88%) had severe acne, 11,718 (43.27%) were active smokers, and 15,365 (56.73%) were nonsmokers at the time of interviews. Active smokers showed a significantly lower prevalence of severe acne (0.71%) than nonsmokers (1.01%) (P=0.0078). An inverse dose-dependent relationship between severe acne prevalence and daily cigarette consumption became significant from 21 cigarettes a day (χ2 and trend test: P<0.0001), odds ratio: 0.2 (95% CI: 0.06–0.63). The study did not aim to establish a temporal correlation, and passive smoking and acne treatments were not measured. Previous in vitro and clinical studies strongly support an association with nicotine. We suggest a trial with topical nicotine treatment for acne to further investigate this association.
The Israel Defense Forces implemented a pilot teledermatology service in primary clinics.
To assess user satisfaction and clinical short-term effectiveness of a computerized store and forward ...teledermatology service in urban and rural units.
A multi-center prospective uncontrolled cohort pilot trial was conducted for a period of 6 months. Primary care physicians referred patients to a board-certified dermatologist using text email accompanied by digital photographs. Diagnosis, therapy and management were sent back to the referring PCP. Patients were asked to evaluate the level of the CSAFTD service, effect of the service on accessibility to dermatologists, respect for privacy, availability of drugs, health improvement and overall satisfaction. PCPs assessed the quality of the teledermatology consultations they received, the contribution to their knowledge, and their overall satisfaction.
Tele-diagnosis alone was possible for 95% (n=413) of 435 CSAFTD referrals; 22% (n=95) of referrals also required face-to-face consultation, Satisfaction with CSAFTD was high among patients in both rural and urban clinics, with significantly higher scores in rural units. Rural patients rated the level of service, accessibility and overall satisfaction higher than did urban patients. PCPs were satisfied with the quality of the service and its contribution to their knowledge. Rural physicians rated level of service and overall satisfaction higher than did urban physicians. Tele-referrals were completed more efficiently than referral for face-to-face appointments.
CSAFTD provided efficient, high quality medical service to rural and urban military clinics in the IDF.
