Background
Warthin-like variant of papillary thyroid carcinoma (WLV-PTC) is a relatively rare variant of papillary thyroid carcinoma with favorable prognosis. However, preoperative diagnosis using fine-needle aspiration (FNA) specimens is challenging especially with lymphocytic thyroiditis characterized by Hürthle cells and lymphocytic background. To determine a helpful cytological differential point, we compared WLV-PTC FNA findings with conventional papillary thyroid carcinoma with lymphocytic thyroiditis (PTC-LT) and conventional papillary thyroid carcinoma without lymphocytic thyroiditis (PTC) regarding infiltrating inflammatory cells and their distribution. Preoperative diagnosis or potential for WLV-PTC will be helpful for surgeons to decide the scope of operation.
Methods
Of the 8,179 patients treated for papillary thyroid carcinoma between January 2007 and December 2012, 16 patients (0.2%) were pathologically confirmed as WLV-PTC and four cases were available for cytologic review. For comparison, we randomly selected six PTC-LT cases and five PTC cases during the same period. The number of intratumoral and background lymphocytes, histiocytes, neutrophils, and the presence of giant cells were evaluated and compared using conventional smear and ThinPrep preparations.
Results
WLV-PTC showed extensive lymphocytic smear with incorporation of thyroid follicular tumor cell clusters and frequent histiocytes. WLV-PTC was associated with higher intratumoral and background lymphocytes and histiocytes compared with PTC-LT or PTC. The difference was more distinct in liquid-based cytology.
Conclusions
The lymphocytic smear pattern and the number of inflammatory cells of WLV-PTC are different from those of PTC-LT or PTC and will be helpful for the differential diagnosis of WLV-PTC in preoperative FNA.

Abstract PDF

Focal segmental glomerulosclerosis (FSGS) is characterized by focal and segmental obliteration of glomerular capillary tufts with increased matrix. FSGS is classified as collapsing, tip, cellular, perihilar and not otherwise specified variants according to the location and character of the sclerotic lesion. Primary or idiopathic FSGS is considered to be related to podocyte injury, and the pathogenesis of podocyte injury has been actively investigated. Several circulating factors affecting podocyte permeability barrier have been proposed, but not proven to cause FSGS. FSGS may also be caused by genetic alterations. These genes are mainly those regulating slit diaphragm structure, actin cytoskeleton of podocytes, and foot process structure. The mode of inheritance and age of onset are different according to the gene involved. Recently, the role of parietal epithelial cells (PECs) has been highlighted. Podocytes and PECs have common mesenchymal progenitors, therefore, PECs could be a source of podocyte repopulation after podocyte injury. Activated PECs migrate along adhesion to the glomerular tuft and may also contribute to the progression of sclerosis. Markers of activated PECs, including CD44, could be used to distinguish FSGS from minimal change disease. The pathogenesis of FSGS is very complex; however, understanding basic mechanisms of podocyte injury is important not only for basic research, but also for daily diagnostic pathology practice.

Abstract PDF

Background
Segmental glomerulosclerosis without significant mesangial or endocapillary proliferation is rarely seen in IgA nephropathy (IgAN), which simulates idiopathic focal segmental glomerulosclerosis (FSGS). We recently recognized aberrant blood vessels running through the adhesion sites of sclerosed tufts and Bowman’s capsule in IgAN cases with mild glomerular histologic change.
Methods
To characterize aberrant blood vessels in relation to segmental sclerosis, we retrospectively reviewed the clinical and histologic features of 51 cases of FSGS-like IgAN and compared them with 51 age and gender-matched idiopathic FSGS cases.
Results
In FSGS-like IgAN, aberrant blood vessel formation was observed in 15.7% of cases, 1.0% of the total glomeruli, and 7.3% of the segmentally sclerosed glomeruli, significantly more frequently than in the idiopathic FSGS cases (p = .009). Aberrant blood vessels occasionally accompanied mild cellular proliferation surrounding penetrating neovessels. Clinically, all FSGS-like IgAN cases had hematuria; however, nephrotic range proteinuria was significantly less frequent than idiopathic FSGS.
Conclusions
Aberrant blood vessels in IgAN are related to glomerular capillary injury and may indicate abnormal repair processes in IgAN.

Abstract PDF

Tubulointerstitial nephritis (TIN) is the most common form of renal involvement in IgG4-related disease. It is characterized by a dominant infiltrate of IgG4-positive plasma cells in the interstitium and storiform fibrosis. Demonstration of IgG4-positive plasma cells is essential for diagnosis, but the number of IgG4-positive cells and the ratio of IgG4-positive/IgG-positive plasma cells may vary from case to case and depending on the methods of tissue sampling even in the same case. IgG4-positive plasma cells can be seen in TIN associated with systemic lupus erythematosus, Sjögren syndrome, or anti-neutrophil cytoplasmic antibody–associated vasculitis, which further add diagnostic confusion and difficulties. To have a more clear view of IgG4-TIN and to delineate differential points from other TIN with IgG4-positive plasma cell infiltrates, clinical and histological features of IgG4-TIN and its mimickers were reviewed. In the rear part, cases suggesting overlap of IgG4-TIN and its mimickers and glomerulonephritis associated with IgG4-TIN were briefly described.

Background

Pre-existing non-neoplastic renal diseases or lesions may influence patient renal function after tumor removal. However, its description is often neglected or omitted in pathologic reports. To determine the incidence and clinical significance of non-neoplastic lesions, we retrospectively examined renal tissues obtained during 85 radical nephrectomies for renal cell carcinoma.

Methods

One paraffin-embedded tissue block from each case containing a sufficient amount of non-tumorous renal parenchyma was cut and processed with hematoxylin and eosin and periodic acid-Schiff methods. Non-neoplastic lesions of each histological compartment were semi-quantitatively and quantitatively evaluated.

Results

Among the various histologic lesions found, tubular atrophy, arterial intimal thickening, and glomerulosclerosis were the most common (94.1%, 91.8%, and 88.2%, respectively). Glomerulosclerosis correlated with estimated glomerular filtration rate at the time of surgery, as well as at 1- and 5-years post-surgery (p=.0071), but tubulointerstitial fibrosis or arterial fibrous intimal thickening did not. Post-hoc analysis revealed that glomerulosclerosis of more than 20% predicted post-operative renal function. However, its significance disappeared when gender and age were considered.

Conclusions

In conclusion, non-neoplastic lesions, especially with regard to glomerulosclerosis percentage, should be described in pathology reports to provide additional information on renal function decline.

Abstract PDF

Background

To define the exact boundary of the intrathyroid and extrathyroid aspects of a gland when determining the extent of cancer invasion, we plan to clarify the definition of sizable vascular structures, which is one of the helpful histologic clues in determining a minimal extrathyroid extension. We hypothesized that arterial wall thicknesses in extrathyroid soft tissue would be significantly different from the arteries in the thyroid parenchyma.

Methods

Twenty cases of papillary carcinoma were selected. The numbers and wall thicknesses of the arteries and arterioles in intrathyroid and extrathyroid tissue were evaluated. The absence of nerve tissue in the thyroid gland was confirmed using the S-100 protein immunohistochemical stain.

Results

The comparison of the mean thicknesses of the total arteries between the extrathyroid and intrathyroid tissues in the retrospective study (26.88 µm vs. 15.07 µm, respectively) and the prospective study (35.24 µm vs. 16.52 µm, respectively) revealed significant differences (p=0.000). The greatest thickness of the intrathyroid arteries was 67.93 µm.

Conclusions

According to our results, the study showed that the extrathyroidal arteries were significantly thicker than the intrathyroidal arteries. We suggest that the sizable blood vessels of extrathyroidal arteries should be greater than 67.93 µm in thickness.

Abstract PDF

Background

Examination of urine for decoy cells (DCs) is a useful screening test for polyomavirus (PV) activation. We explored the significance of the amount of DCs in persistent shedding, PV nephropathy and acute rejection.

Methods

A case-controlled study was performed in 88 renal allograft patients who had DCs detected at least once in four or more urine samples.

Results

Fifty one patients were classified into the high-grade shedding group (HG) and 37 patients into the low-grade shedding group (LG) according to DC shedding (≥10 or <10 DCs/10 high power field [HPF]). DC shedding of more than three consecutive months was significantly more prevalent in the HG as compared with their LG counterparts (p<0.0001). Urinary DCs were present for more than one year in 29.4% of the HG and 8.1% of the LG. Real-time polymerase chain reaction for PV was higher in both urine (51.4% vs. 11.1%) and plasma (9.1% vs. 0%) of the HG than the LG. The prevalence of PV nephropathy was higher in the HG than the LG (p=0.019). However, there was no significant difference in the prevalence of acute rejection.

Conclusions

Shedding of ≥10 DCs/10 HPF is associated with sustained shedding, polymerase chain reaction positivity and PV nephropathy, but not a predictor of acute rejection.

Abstract PDF

BACKGROUND
To standardize renal biopsy reporting and diagnosis, The Renal Pathology Study Group of the Korean Society of Pathologists (RPSKSP) has developed a renal pathology reporting format for the native and allograft kidney.
METHODS
A consensus checklist of a provisional renal biopsy format was sent to all members of the RPSKSP. Feed back opinions regarding the practical application of the checklist to the diagnostic work were received.
RESULTS
Kidney biopsies require three essential examinations: by light microscopy, immunofluorescence (IF), and electron microscopy (EM). A final report of a renal biopsy should include information on specimen adequacy and a description of the morphologic change using a systematic semiquantitative method for each of the compartments, with optional separate IF and EM reports.
CONCLUSIONS
A standard renal biopsy report format is important in establishing clinicopathologic correlations, making reliable prognostic considerations, comparing the findings in sequential biopsies and evaluating the effects of therapy.

Abstract PDF

BACKGROUND
The histological subtypes of focal segmental glomerulosclerosis (FSGS) have different significance and influence clinical presentations and outcomes in patients with FSGS. However, no such data has been reported in Korea.
METHODS
We reviewed renal biopsy specimens of 69 adult patients who were diagnosed with idiopathic FSGS between 2000 and 2008, subclassified them according to the Columbia classification and correlated the results with clinical findings.
RESULTS
The frequencies of the FSGS subtypes were not otherwise specified (NOS) (n = 28), tip (n = 21), perihilar (n = 11), collapsing (n = 5) and cellular types (n = 4) in descending order. Nephrotic syndrome was more common in patients with the tip and collapsing types than the perihilar type. The prevalence of chronic kidney disease stage 4/5 at the time of renal biopsy was significantly higher in patients with the cellular type than the NOS or the tip type. The remission rate after treatment tended to be higher in patients with the NOS type (22.0%) and the tip type (15.2%) than the perihilar (6.8%) and collapsing types (3.4%).
CONCLUSIONS
Classifying FSGS subtypes may be helpful to predict of clinical features and renal outcomes.

Abstract PDF: BACKGROUND
Fine needle aspiration, which is known as the most accurate and cost-effective method for diagnosis of thyroid nodule, still may result in indeterminate cases that are pauci-cellular and show minor nuclear atypia, but most cases are associated with suspicion of papillary thyroid carcinoma (PTC). A B-type Raf kinase (BRAF) mutation was found in about half of PTCs and galectin-3 was expressed by malignant tumors, helping us to differentiate malignancies from benign lesions.
METHODS
Cases studied included histologically 44 confirmed PTC cases and 18 benign cases previously diagnosed as suspicious of PTC using cytologic examination. Cases were analyzed for galectin-3 expression by immunohistochemical staining and BRAF mutation by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) with a new restriction enzyme.
RESULTS
All 44 cases of PTC and 8 of 18 benign controls expressed galectin-3. BRAF mutations were found in only 9 of the 44 PTC cases. Assessment of galectin-3 expression demonstrated high sensitivity but low specificity. Evaluation of BRAF mutation revealed high specificity and low sensitivity.
CONCLUSIONS
This study suggests that the combined application of these two methods for PTC of suspicious cytology is complementary.

Abstract PDF: Carcinoid tumor of the middle ear cavity is a rare neoplasm of low malignant potential. It grows slowly and rarely metastasizes. We recently experienced a case of carcinoid tumor of the middle ear cavity occurring in a 51-year-old female who was presented with hearing loss and tinnitus of the right ear. A 1 cm sized pinkish soft mass was noted in the promontory of the middle ear. Histologically, the mass was composed of nests and cords of tumor cells with slightly pleomorphic nuclei and eosinophilic cytoplasm. The extracellular matrix was glassy pink, homogeneous and exhibited apple green birefringence under a polarized light microscope after Congo red staining. The tumor cells showed immunoreactivity for cytokeratin, chromogranin A, synaptophysin, neuron-specific enolase and calcitonin. Electron microscopic examination confirmed the presence of neurosecretory granules. The production of calcitonin and amyloid by the tumor cells suggests the possible relationship of this tumor to the thyroid C cells.

Abstract PDF: We experienced a case of primary malignant mixed mullerian tumors (MMMT) of the fallopian tube of FIGO stage I. In addition to endometrioid adenocarcinomas, multiple apparent heterologous elements encompassing myxoid chondrosarcoma, osteosarcoma, myxoid liposarcoma and well differentiated angiosarcoma were recognized as separate nodules. These findings have not been described previously in MMMTs of the female genital tract.
