Section snippets
Materials and methods
Between December 1999 and July 2001, paraffin sections from 83 current neurosurgical tumor cases were analyzed telemicroscopically before routine light microscopic examination. The mean age of patients in this study was 48 (±16) years. The ages ranged from 6 to 76 years. Of the 83 patients, 43 were female and 40 were male. Eighty-two tumor specimens were removed surgically, and 1 specimen was obtained by stereotactic biopsy. Seventy-five patients had primary tumors, and 8 had tumor metastasis
System validation
The 3 neuropathologist participants, in 3 different Polish cities, each worked in a different telecommunications environment. Participant A, in Poznan, worked within a local area network (LAN; 100 Mb/s) with the following outside connections to the Internet: through the Metropolitan Area Network POZMAN (622 Mb/s) and to the National Academic Network POL-34/155 (155 Mb/s). Telepathologic diagnostic sessions were done with a IBM-compatible Pentium II 440 MHz PC with 128 Mb RAM. Video images were
Discussion
Despite advances in molecular diagnostics, paraffin section light microscopy remains the primary method for the diagnosis of most lesions in the central nervous system. In some cases, paraffin sections are augmented with other techniques to corroborate a primary diagnosis rendered from paraffin sections stained with hematoxylin and eosin. The time required to establish final diagnosis varies and depends in part on the complexity of viewed material. Access to expert consultation can be highly

These results are consistent with previous reports that have estimated the accuracy of telepathologic diagnosis as between 91% and 100% [9-14]. There was no significant difference in telepathology and light microscopy diagnoses—the concordance rate for the 2 was almost the same (the mean ratio of correct diagnosis achieved by telepathology and conventional microscopy among the 4 pathologist was 99.26%).
