Abstract PDF: Background
The importance of molecular pathology tests has increased during the last decade, and there is a great need for efficient training of molecular pathology for pathology trainees and as continued medical education.
Methods
The Molecular Pathology Study Group of the Korean Society of Pathologists appointed a task force composed of experienced molecular pathologists to develop a refined educational curriculum of molecular pathology. A 3-day online educational session was held based on the newly established structure of learning objectives; the audience were asked to score their understanding of 22 selected learning objectives before and after the session to assess the effect of structured education.
Results
The structured objectives and goals of molecular pathology was established and posted as a web-based interface which can serve as a knowledge bank of molecular pathology. A total of 201 pathologists participated in the educational session. For all 22 learning objectives, the scores of self-reported understanding increased after educational session by 9.9 points on average (range, 6.6 to 17.0). The most effectively improved items were objectives from next-generation sequencing (NGS) section: ‘NGS library preparation and quality control’ (score increased from 51.8 to 68.8), ‘NGS interpretation of variants and reference database’ (score increased from 54.1 to 68.0), and ‘whole genome, whole exome, and targeted gene sequencing’ (score increased from 58.2 to 71.2). Qualitative responses regarding the adequacy of refined educational curriculum were collected, where favorable comments dominated.
Conclusions
Approach toward the education of molecular pathology was refined, which would greatly benefit the future trainees.

Background
Counting mitoses is subjective and time-consuming. The adjunctive diagnostic utility of a recently reported mitotic marker, phosphohistone H3 (PHH3), was investigated in gastrointestinal stromal tumors (GISTs). Methods: We reviewed 77 GISTs for several proliferative indices. These included the mitotic count per 50 high power fields (HPFs), the immunohistochemical Ki- 67 labeling index and the immunohistochemical PHH3 mitotic index (MI). For comparison, Spearman’s rank correlation and interclass correlation coefficient were used. Results: Mitotic counts ranged from 0–138 (mean, 7.57±2.34) and the PHH3 MI ranged from 0–126 per 50 HPFs (mean, 9.61±2.27). We found a positive correlation between mitotic counts and PHH3 MI (r=0.810, p<.001). The inter-observer correlation coefficient for three participants was 0.975 for mitotic counts and 0.940 for the PHH3 MI. When using the PHH3 MI instead of mitotic counts in the Armed Forces Institute of Pathology (AFIP) stratification criteria, 10 cases were reclassified. In one patient with a mitotic count of 2 and a PHH3 MI of 6 per 50 HPFs, distant metastasis occurred. Conclusions: In GISTs, the PHH3 MI correlated adequately with mitotic counts and can be used as a useful adjunctive to count mitotic figures efficiently.

Abstract PDF

Background

Lymphangioleiomyomatosis (LAM) is a slowly progressive neoplastic disease that predominantly affects females. Usually, LAM affects the lung; it can also affect extrapulmonary sites, such as the mediastinum, the retroperitoneum, or the lymph nodes, although these locations are rare. A localized form of LAM can manifest as extrapulmonary lesions; this form is referred to as extrapulmonary lymphangioleiomyoma (E-LAM). Due to the rare occurrence of E-LAM and its variable, atypical location, E-LAM is often difficult to diagnose. Herein, we report the clinicopathological information from four E-LAM cases, and also review previous articles investigating this disease.

Methods

Four patients with E-LAM were identified at the Samsung Medical Center (Seoul, Korea) from 1995 to 2012. All E-LAM lesions underwent surgical excision.

Results

All patients were females within the age range of 43 to 47 years. Two patients had para-aortic retroperitoneal masses, while the other two patients had pelvic lesions; two out of the four patients also had accompanying pulmonary LAM. In addition, no patient displayed any evidence of tuberous sclerosis. Histologically, two patients exhibited nuclear atypism with cytologic degeneration.

Conclusions

E-LAM should be considered in the differential diagnosis of patients presenting with pelvic or para-aortic masses. We also conclude that further clinical and pathological evaluation is needed in patients with E-LAM and nuclear atypism.

Abstract PDF

Background

Previous studies have suggested an association between usual interstitial pneumonia (UIP) and lung cancer (Ca). However, clinical and histological information is not enough to determine such an association, due to the low incidence and short survival time of patients with both conditions.

Methods

We retrospectively reviewed the clinical and histological records of Ca patients with UIP between January 1999 and August 2013 at the Samsung Medical Center, Seoul, Korea. We found 43 patients who had Ca with UIP (UIP-Ca). Previously reported data of eighty-four patients with UIP-only were included as a comparison group.

Results

Smoking is related to poor prognosis in patients with UIP-Ca, and the number of patients with a high smoking index of more than 30 pack-years significantly increased in UIP-Ca patients compared with UIP-only patients. There is no significant prognostic differentiation between UIP-Ca patients and UIP-only patients. Microscopically, UIP-Ca patients showed characteristically heterogeneous histological patterns and degrees of differentiation. There were many foci of squamous metaplasia or dysplasia at the peripheral area of squamous cell carcinomas.

Conclusions

We report 43 cases of UIP-Ca. Our results suggest that smoking is related to cancer occurrence in UIP patients and poor prognosis in UIP-Ca patients.

Abstract PDF

Background

It has long been recognized that bronchial schwannomas are extremely rare. As such, diagnosing tumors in this extraordinary location can sometimes be problematic.

Methods

We reviewed seven cases of bronchoscopically or surgically resected endobronchial schwannomas and evaluated their clinical and pathologic features.

Results

The present study included five female and two male patients, with ages ranging from 16 to 81 years (mean age, 44.9 years). The clinical presentation varied according to tumor size and location. Patients with more centrally (trachea or main bronchus) located tumors experienced respiratory symptoms (80%) more often than patients with more peripherally (lobar or segmental bronchus) located tumors (0%). Histologically, the tumors were composed of spindle cells that stained with S100 protein. Some of the tumors showed typical Antoni A areas with Verocay body formation. Five of six patients (83.3%) underwent complete tumor removal by rigid bronchoscopy.

Conclusions

Pathologists should consider endobronchial schwannoma in the differential diagnosis of a spindle cell tumor involving the bronchus. Additionally, our results showed that rigid bronchoscopy is an effective tool for tumor removal in endobronchial schwannoma patients.

Abstract PDF: A 75-year-old man was referred to our hospital with intestinal obstruction caused by intussusception. Abdominal computed tomography (CT) revealed seven polypoid masses in the small intestine, while chest CT revealed a mass in the right lower lobe. Preoperative laboratory tests showed white blood cell (WBC) and neutrophil differential counts of 63,630/mm3 and 95%, respectively. The serum granulocyte colony-stimulating factor (G-CSF) was 114 pg/mL, which was elevated (normal range, <18.1 pg/mL). After resection of the small bowel, the WBC count decreased to 20,510/mm3. The pathology showed a poorly differentiated carcinoma with sarcomatous components confirmed by positive immunostaining of cytokeratin (AE1/AE3) and vimentin in the small intestine. Furthermore, immunohistochemistry with specific monoclonal antibodies against G-CSF was positive. A lung biopsy revealed the same histological findings as the small intestine lesion. Therefore, the patient was diagnosed as having a G-CSF producing sarcomatoid carcinoma of the lung with metastasis to the small intestine.

Abstract PDF: Intravascular leiomyosarcomas of the femoral vein are extremely rare. Our patient was initially diagnosed with a deep vein thrombosis based on ultrasonography and venography. The thrombectomy specimen consisted of typical spindle cells with variable anaplasia arranged in a fasciculating and interlacing pattern. The final diagnosis was proved to be an intravascular leiomyosarcoma confirmed by immunohistochemical studies for smooth muscle actin, desmin, vimentin, CD34 and CD68.

Abstract PDF: BACKGROUND
The overexpression of cyclin D1 and galectin-3 and the loss of p27 in thyroid cancers have recently been reported by many studies. The S-phase kinase associated protein 2 (skp2) plays an important role in the degradation of p27. We compared the correlation of the expressions of galectin-3, p27, cyclin D1 and skp2 in thyroid lesions.
METHODS
Sixty five cases were included in this study and immunohistochemical staining for galectin-3, skp2, p27 and cyclin D1 was performed.
RESULTS
The expression of galectin-3 increased in the order of nodular hyperplasia, follicular adenoma, follicular carcinoma and papillary carcinoma (p<0.01). The expression rate of skp2 was 0% for nodular hyperplasia, 16.7% for follicular adenoma, 33.3% for follicular carcinoma and 16.7% for papillary carcinoma. The loss of the expression of p27 was more frequently detected in papillary carcinoma as compared with nodular hyperplasia (p<0.01). The increased expression of cyclin D1 was noted in follicular adenoma and carcinoma as compared with nodular hyperplasia (p=0.043). The expression of galectin-3 was related with the loss of a p27 expression (p<0.01), and the expression of skp2 was related with the expression of the cyclin D1 (p=0.022).
CONCLUSIONS
Galectin-3 appears to be the most useful marker for making the diagnosis of thyroid lesions. The loss of a p27 expression can help differentiate nodular hyperplasia and papillary carcinoma, and the determining the expression of cyclin D1 may be helpful for the differential diagnosis of nodular hyperplasia and follicular neoplasm.
