The Utility of Digital Clinical Photographs in Dermatopathology

Background and ObjectiveTechnological improvements have helped digital cameras become widely available and inexpensive. Dermatopathologic diagnosis is often aided by clinical information. The purpose of this study was to determine whether submitting a digital image along with a skin biopsy provides additional helpful information to the dermatopathologist.MethodsDigital pictures were taken of the lesion being biopsied and were submitted along with routine paper work to the dermatopathologists. The dermatopathologists interpreted the skin biopsy as usual without viewing the digital image, and then later viewed the submitted picture. The dermatopathologists evaluated the help provided by the image.ResultsA clinical digital image was helpful in confirming the initial diagnosis and narrowing down the differential diagnosis (p < 0.001). Including pictures did not change the diagnosis, result in an increase in the differential diagnosis, or result in fewer or additional step sections being performed. Digital imaging of inflammatory disorders was felt to be good help in 43% of the biopsies and narrowed down the differential diagnosis in 31%.ConclusionIn certain cases the inclusion of a digital image may help a dermatopathologist. Digital imaging was found to be most helpful in evaluation of inflammatory disorders.SommaireAntécédents et objectifsGrâce aux améliorations technologiques, les appareils photos numériques sont devenus faciles à acquérir et bon marché. Le diagnostic dermatopathologique est souvent appuyé par les données cliniques. L’objectif de la présente étude est de déterminer si une image numérique soumise avec la biopsie de la peau fournit une information additionnelle utile au dermatopathologiste.MéthodesDes photos numériques des lésions subissant une biopsie ont été soumises aux dermatopatologistes avec la documentation régulière. Les dermatopathologistes ont d’abord interprété la biopsie comme d’habitude sans consulter les photos et ont regardé les photos par la suite. Ils ont évalué I’aide fournie par les images.RésultatsL’image numérique clinique a été utile dans la confirmation du diagnostic initial et pour restreindre le diagnostic différentiel (p < 0.001). L’ajout de photos n’a pas modifié le diagnostic, résulté en une augmentation du diagnostic différentiel ou en un changement du nombre d’étapes nécessaires à la biopsie. L’ajout de photos numériques d’éruptions cutanées a aidé dans 43% des biopsies et a limité le diagnostic différentiel dans 31% des cas.ConclusionDans certains cas, I’ajout d’une image numérique peut aider le dermatopathologiste. Les images sont surtout utiles dans I’évaluation des èruptions cutanées.
