This study was undertaken to know the extent of apoptosis, expression of bcl-2 and proliferating cell nuclear antigen (PCNA) in uterine cervical intraepithelial neoplasia (CIN; 15 cases) and invasive carcinoma (27 cases) and to evaluate them as a prognostic marker. Apoptosis was analysed by using the in situ apoptosis detection kit and bcl-2 and PCNA were detected by the immunohistochemical method. The results were as follows: Apoptotic indices (AI) in the invasive carcinoma (mean: 4.3) were 10-times higher than that in the CIN (mean: 0.43). Bcl-2 was expressed 60% of the cases in the dysplastic cells of the CIN II and CIN III, 33.3% of cases in the invasive carcinoma and not expressed in the CIN I except basal cells. The expression of the PCNA was increased by the grades of CIN and was strong in invasive carcinoma. The mean survival time of the patient with invasive carcinoma was significantly decreased in the higher AI index (above 4.3) than in the lower AI index (below 4.3). There was no significant correlation between the extent of apoptosis and the expression of bcl-2. According to the above results, AI are able to be used as an independent prognostic marker in the invasive cervical carcinoma, and bcl-2 and PCNA have an important role in the tumorigenesis of uterine cervical carcinoma.

Human papillomavirus (HPV) 16/18 is a causative agent of uterine cervical carcinoma. HPV 16/18 can alter cell cycle regulation through apoptosis. Bcl-2 is an important regulatory gene of apoptosis. A study was done to evaluate the relation between HPV 16/18 and bcl-2 and apoptosis in 21 cases of carcinoma in-situ (CIS), 5 cases of microinvasive carcinoma and 23 cases of invasive squamous cell carcinoma. HPV 16/18 was detected by hybrid capture system (HCS), bcl-2 protein by immunohistochemical method and apoptosis by using the hematoxylin-eosin stained slide. The results were as follows: Expression of the bcl-2 protein was 43% (9/21) in CIS and 26% (6/23) in invasive carcinoma. Expression of the bcl-2 protein was 42% (5/12) in CIS with HPV 16/18 infection, 44% in CIS without HPV 16/18 infection, 20% (2/10) in invasive carcinoma with HPV 16/18 infection and 31% (4/13) in invasive carcinoma without HPV 16/18 infection. Mean apoptotic index (mAI) was 3.36 in CIS, 5.23 in microinvasive and 6.25 in invasive carcinoma. mAI was 3.66 in CIS with HPV 16/18 infection, 2.86 in CIS without HPV 16/18 infection, 6.18 in invasive carcinoma with HPV 16/18 infection and 6.30 in invasive carcinoma without HPV 16/18 infection. Based on these results, we conclude that there are no correlation between HPV infection and bcl-2, and between HPV infection and apoptosis in invasive and in situ carcinoma of the uterine cervix, and apoptosis is increased according to tumor progression.

Plexiform schwannoma is a rare benign tumor arising from the peripheral nerve sheath and characterized by a multinodular and plexiform growth pattern. This tumor usually arises sporadically. In rare cases, plexiform schwannomas have been associated with neurofibromatosis type 2. Plexiform schwannoma should be differentiated from plexiform neurofibroma, because the latter is pathognomonic tumor of neurofibromatosis type 1 and has a potential of malignant transformation. We report a case of multiple plexiform schwannomas associated with bilateral acoustic neuromas and meningioma.

Torsion of a mucocele of the vermiform appendix is an extremely rare condition and also a rare cause of an acute abdomen with a clinical presentation that is indistinguishable from acute appendicitis, and thus, the condition is diagnosed during operation. Here, the authors describe the case of a 78-year-old female, who presented with intermittent abdominal pain. The appendix had a pelvic position and the torsion was counterclockwise. In addition, the torsion was associated with mucocele of the appendix, which was considered a secondary factor of torsion. Appendectomy and drainage were performed.

Eccrine spiradenomas are clinically characterized by a solitary, tender mass and they are situated on the upper parts of the body, predominantly on the ventral aspect. We herein report two cases of eccrine spiradenoma in 35-year-old man and 53-year-old woman, which located on upper extremity and inguinal region. The masses are round, well circumscribed and measuring 0.7x0.5x0.5 cm, 5x4.5x3 cm in size, respectively. Histopathologically, the tumor consists of masses of two types of cells, intensely staining cells and pale staining cells, usually arranged in chains, cords and pseudoglands. Immunostainings for low molecular cytokeratin, high molecular cytokeratin, carcinoembryonic antigen, and S-100 protein show positivity in neoplastic cells. Electron microscopically, the tumor was composed of three types of cells, i. e. 1) round or ovoid tumor cells in shape with scanty cytoplasm and poorly developed intracytoplasmic orgenelles, 2) spindle shaped dark cells interconnected by desmosomes, 3) large epithelial cells with abundant cytoplasm and cytoplasmic intermediate filaments which formed glandular structures. The large epithelial cells joint each other by desmosomal attachments and luminal cells featured small numbers of microvilli, but either secretory granules nor ductal type granules were noticed.

There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

Antiphospholipid antibody syndrome (APS) has been considered as a distinct clinical entity, usually associated with systemic lupus erythematosus (SLE) or with other connective tissue disease. Prominent clinical features include venous thrombosis, arterial occlusions, thrombocytopenia, hemolytic anemia, recurrent fetal loss, livedo reticularis and neurologic manifestations. Antiphospholipid antibodies (aPL) represent a spectrum of phospholipid-binding antibodies, including the lupus anticoagulant(LA), anticardiolipin antibody (aCL), and the biologic false-positive serologic test for syphilis (BFP-STS). Primary antiphospholipid syndrome (PAPS) which has been recently described is a complication of autoimmune aPL with lack of serologic and clinical features of SLE. We present a young female patient with PAPS who showed progressive dementia, diffuse cerebral atrophy, renal arteriolar occlusions, livedo reticularis, and valvular heart disease. To our knowledge, our patient is the first described with the clinical and mangetic resonance imaging(M-RI) findings in this entity.
