- BACKGROUND
Second opinion diagnosis of outside pathology slides is a common practice for efficient and proper patient management. We analyzed cytology slides from outside hospitals submitted for a second opinion diagnosis to determine whether the second opinion diagnosis had any influence on patient care.
METHODS
We reviewed 1,153 outside cytology slides referred to Asan Medical Center for second opinions from January, 2007, to December, 2007. All cases were categorized into three groups; no diagnostic discrepancy, minor diagnostic discrepancies (no impact on the management), and major diagnostic discrepancies (significant impact on the management and subsequent follow-up).
RESULTS
The thyroid was the most common organ system (933 cases, 80.9%). Forty cases (3.6%) belonged to the major diagnostic discrepancy group and 149 cases (12.8%) to the minor discrepancy group. For validation of second opinion diagnoses in major discrepancy cases, subsequent biopsy or surgical resection specimens and clinical information were reviewed, which were available in 29 cases. The second opinion diagnoses resulted in alteration of clinical management in 21 of 29 cases.
CONCLUSION
For all referred patients, second opinion diagnosis is important and mandatory for appropriate patient care.

- BACKGROUND
Juvenile ossifying fibroma (JOF) is defined as a variant of the ossifying fibroma, and the latter includes juvenile trabecular ossifying fibroma (JTOF) and juvenile psammomatoid ossifying fibroma (JPOF). JOF can be distinguished from other craniofacial fibroosseous lesions by its tendency to recur and its clinical mimicry of malignant bone tumors, but some clinical and histological features of JOF overlap with the other fibro-osseous lesions as well. We aimed to identify the clinicopathologic definition of JOF.
METHODS
Forty-two cases of fibro-osseous lesions were reviewed and they were classified into JOF, fibrous dysplasia (FD) and ossifying fibroma (OF).
RESULTS
JTOF had long, slender and anastomosing trabeculae of osteoid in a fibrocellular stroma, and JPOF had small ossicles resembling psammoma bodies with a thick collagenous rim in the fibrous stroma, which are features that differ from those of FD and OF. Radiologically, JOF and OF showed a well-defined lesion but FD exhibited an ill-defined lesion.
Clinically, the average age of the JOF patients was the youngest, followed by OF and FD. For JOF, three cases had rapid growth and two others showed recurrences. JOF mainly occurred in the paranasal sinuses, OF in the mandible and FD in any craniofacial bone.
CONCLUSION
We demonstrated the distinct characteristics of JOF and these features may be helpful for the diagnosis and management of this malady.
