A Novel “Work from Home Setup” for Telepathology Second Opinion of Oral Lesions

The advent of smartphones with high-resolution cameras has opened up new possibilities in the field of telepathology for a second opinion especially in the COVID-19 era. The aim of this study was to evaluate the intraobserver concordance of a novel “work from home setup” with conventional microscopy diagnosis taken as the gold standard. A total of 90 cases of oral biopsies diagnosed by one pathologist were photographed with a smartphone camera. The static images were transferred via Google Drive and viewed on a 40-inch LED television screen connected by an HDMI cable to a laptop by the same pathologist. A wash-off period of 4 months was provided to avoid recall bias. The intraobserver concordance of Google Drive transfer and conventional microscopy was calculated. The cases in which the conventional slide microscopy and smartphone image diagnosis (SPID) via Google Drive were concordant constituted 98.9% (89/90), and the ones with discordant diagnoses made up 1.1% (01/90). Smartphone-assisted telepathology can be useful for a second opinion. The images can be stored on a Google Drive and then downloaded to a personal computer and viewed on large-screen television to attain high levels of diagnostic accuracy.
