We report the results of a study designed for assessment of the diagnostic accuracy and usability of internet-based digital microscopy: the dynamic real-time telepathology system (Coolscope) and the Virtual microscopy (Aperio Scan Scope) system, in the context of pulmonary pathology. The systems were implemented to the routine pulmonary pathology workflows and used for the intra-operative frozen-section primary diagnosis as well as for the secondary (consultative) diagnosis. The histological material presented for the teleconsultations included the samples of lung parenchyma, bronchial biopsy and resected lung/bronchi tumours. For the primary diagnosis 4 categories of material can be distinguished (304 samples): 1) the frozen sections of lung tumours, resected bronchial margins and lymph nodes; 2) fine needle aspiration [FNA] biopsies (TBNA; EBUS-TBNA, EUS-FNA; 3) oligobiopsies of bronchus, oesophagus, skin; and 4) exfoliative cytology. The telepathology diagnoses compared with conventional light microscopy diagnoses showed very high concordance for the Coolscope and Aperio Virtual Slide modality: 87.5% and 100%, respectively - within the group of teleconsultations. For the frozen sections, the primary telediagnoses were concordant with the light microscopy paraffin sections diagnoses in 100% for Aperio; and in 97.5% for Coolscope. An excellent agreement (100%) was seen in the telediagnoses and conventional slides diagnoses for FNA, oligobiopsies and cytology - for both telepathology systems. These results provide some encouragement for the implementation of Coolscope and virtual slide-based telepathology (Aperio) system to the routine histopathological diagnostics.
