Abstract
PDF Background This study investigates the prevalence of human papillomavirus (HPV) 52 and 58 genotypes among women residing in Busan, and the expression of p16 and p53 proteins in cervical neoplasia with HPV 52 and 58 infections.
Methods A total of three hundred fifteen cases were analyzed using the HPV DNA chip test for HPV genotypes, and of these, we retrospectively examined p16 and p53 expression in 62 cases of cervical tissues infected with HPV 52 and 58 using immunohistochemistry.
Results HPV 52 and 58 genotypes were identified in 62 (54.9%) out of 113 high-risk, HPV-infected cases. Of the cases examined, there were 19 single HPV 52 infections (16.8%), 23 single HPV 58 infections (20.4%), 4 multiple HPV 52 infections (3.5%), and 16 multiple HPV-58 infections (14.2%). Immunoreactivity of p16 and p53 was observed in 41 (66.1%) and 23 (37.1%) of the 62 cases of cervical neoplasia infected with HPV 52 and 58 genotypes, respectively.
Conclusions This study demonstrates a high prevalence of HPV 52 and 58 genotypes, in addition to HPV 16, among high-risk strains of cervical neoplasia in Korea. These findings suggest that development of more vaccines would be beneficial for the prevention of the various HPV genotypes.

Abstract
PDF
- Apocrine carcinoma arising from the apocrine sweat glands is a rare cutaneous malignant tumor which occurs predominantly in the axilla of elderly individuals. The typical histologic features of apocrine carcinoma is within a well developed glandular lumina with abundant eosinophilic cytoplasm and evidence of decapitation secretion. In rare instances, predominant signet ring cell features in apocrine carcinoma has been reported. We experienced a case that occured in the right axilla of a 59-year-old. Histopathologic examination showed a solid tumor that extended from the upper dermis into the subcutis, with a delicate infiltrate of epithelial cells. The cells had granular amphophilic cytoplasm, predominantly showed distinct signet ring cell morphology, and were strongly positive for epithelial mucin. Both lysozyme and gross cystic disease fluid protein-15 were identified in the tumor cells. We diagnosed this to be a case of primary signet ring cell apocrine carcinoma of the axilla after several immunohistochemical and clinical evaluations.

Abstract

- BACKGROUND
The grey zone of cervical cytology, and in particular atypical squamous cells, cannot exclude HSIL (ASC-H) causes diagnostic difficulties and increases medical expenses. We analyzed p16INK4a expression in ASC-H liquid-based cytology specimens (LBCS) to develop more effective methods for the management of ASC-H patients.
METHODS
We carried out p16INK4a immunostaining with 57 LBCS of ASC-H diagnostic categories, all of which were histologically cofirmed and 43 cases of which were compared with the results of a human papillomavirus (HPV) chip test.
RESULTS
p16INK4a immunostaining with ASC-H LBCS was positive in 20% (3/15) of cervicitis, 25.0% (3/12) of tissue-low-grade squamous intraepithelial lesion, 75.0% (18/24) of tissue-high grade squamous intraepithelial lesion (HSIL), and 100% (6/6) of invasive cancer cases. The positivity of p16INK4a in LBCS was correlated with higher grade of histologic diagnosis (r=0.578, p=0.000). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of p16INK4a immunostaining for the prediction of tissue-HSIL+ were 80.0%, 77.8%, 80.0%, and 77.8%, respectively. The sensitivity, specificity, PPV, and NPV of p16INK4a immunostaining plus HPV chip test for predicting tissue-HSIL+ were 71.2%, 86.4%, 84.2%, and 79.2%.
CONCLUSIONS
p16INK4a immunostaining as well as HPV chip testing with remaining LBCS with ASC-H are useful objective markers for the prediction of tissue-HSIL+. -

Abstract
PDF
- Lipofibromatosis is a recently described rare benign fibrofatty tumor of childhood. It typically forms as an ill defined, slowly growing, painless mass. We present here the case of lipofibromatosis that occurred in a 21-year-old male who had complained of a bulging enlarged mass involving the right thigh and prepatella area for the previous 1 year. Magnetic resonance imaging showed an ill-defined reticular infiltration in the subcutaneous layer with subtle linear enhancement and high T2 signal intensity. The mass was surgically excised and it displayed an 11.0x5.5x1.5 cm-sized adipose appearance without encapsulation. Microscopically, the tumor was composed of alternating streaks of mature adipose tissue and a fibroblastic component that mainly involved the septa of adipose tissue. On immunohistochemical study, the fibroblastic component was positive for S-100, CD99, CD34, actin and bcl-2. He has shown an eventful recovery for 6 months after surgery.

Abstract
PDF
- BACKGROUND
C1q nephropathy (C1qN) is a controversial diagnostic entity defined by Jennette and Hipp in 1985. The prevalence is very low and a few large scale studies have been reported. Application of the criteria for clinical diagnostics of C1qN may cause confusion with other glomerulonephropathies, such as minimal change disease (MCD) or focal segmental glomerulosclerosis (FSGS). In order to clarify the confusion with glomerulonephropathies, we did this study to identify the clinicopathological characteristics and the exact disease entity of C1qN.
METHODS
A total of 5,258 kidney biopsies at Kangnam St Mary's Hospital were reviewed. Twenty three cases (0.44%) met the criteria of C1qN. Twenty eight cases showing dominant C1q deposits without electron dense depostis (EDD) grouped as C1q+EDD-, and previously diagnosed typical cases of MCD and FSGS were selected for this study. Four groups were compared to each other with regard to the clinical and pathological aspects of the disease. RESULTS: C1qN patients had an average age of 30.4 years. Eighteen were males and 5 were females. Eighty seven percent had proteinuria and 18% had hematuria. By electron microscopy analysis, 100% had mesangial EDD and 47.8% showed foot process effacement. C1qN had some significant differences compared with C1q+EDD-, MCD and FSGS. CONCLUSIONS: C1qN is clinically and morphologically different from MCD and FSGS. However, additional long term studies are needed to fully define C1qN from other glomerulonephritis with C1q deposits.
