History: A 50-year-old female school teacher presented with a two year history of swelling of the right third toe. X-rays were read as being commensurate with a malignant tumor (Fig. 1), and an en-bloc resection of the third ray was performed. A hard, multinodular, tan-gray 5.0 cm mass was found to primarily involve the proximal phalangeal bone and adjacent soft tissue.
Microscopic sections showed the tumor to break out of bone and to involve surrounding tissues with extension up to the deep dermis (Fig. 2). The tumor displayed an osseous matrix consisting mostly of woven and… More

We seemed to have recovered from a “hack attack” from this last week (or at least Google and stopbadware are finally unblocking us) after much poring over and reinstalling of files.
Preventive steps have also been taken. Hopefully this will calm things down for awhile.

If you have submitted any forms between July 1st and 6th, please resubmit them by email. Thanks.
Update: Forms appear to be working after turning off Ajax.
