We have experienced a case of neurofibromatosis with unusual giant pigmentation, which presents itself as a 28 cm x 40 cm sized, serrated bordered light brownish patch speckled with small dark hyperpigmented macules on his back. Histopathologic examinations of light brown patch and speckles showed only an increase in basal melanin pigmentation.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

PURPOSE: Because cryptorchid testes are known to undergo histopathologic changes affecting development, maturation, and tertility, early surgical correction is usually recommended. However there are differing opinions concerning whether retractile testes are affected by similar changes and also whether there is a need for surgical treatment. We aimed to assess the histopathologic changes in retractile testis by studying the changes in testes artificially placed back in the abdomen after they have descended to scrotum in experimental rat models. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 3 groups; a control group(controls), prepubertal ascent group (P) in which testis were placed back intraabdominally by bilateral inguinal canal obstruction at 6 weeks, a neonatal group(N) in which intraabdminal testis was induced by bilateral inguinal canal obstruction at birth. The relative weight of the testis, morphology of the seminiferous tubules including Leydig cells, tubular degeneration phase(TDP), spermatogonia per tubules(S/T), and Sertoli cell index (SCI) of these three groups were analyzed and compared. RESULTS: The relative weight of testis was significantly decreased in the group of N(0.0016+/-0.001) and P(0.0015+/-0.0002) compared to controls(0.0037+/-0.0002) (p<0.05). The S/T value was also decreased in P(2.05+/-18.2) and N(73.2+/-32.4) when compared to controls (360.2+/-21.3). Similar changes were observed in SCI of both P(64.5+/-6.4) and N (91.2+/-14.2) when compared to controls (227.9+/-31.1). Only minority of N and P showed higher TDP values. However, although statistically insignificant, TDP was increased in both P and N when compared to controls. The Leydig cells in N and P showed cellular distortion and hypertrophy. CONCLUSIONS: This study demonstrate that prepubertal ascent, similar to that of innate cryptorchid testis, also can induce histopathologic changes such as changes in testicular seminiferous tubule, decrease in the S/T value and decrease in SCI value. Our findings supports that hypothesis that retractile testis may cause histological damage thus surgical correction may also be warranted similar to in case of genuine cryptorchism.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix with highly aggressive clinical behavior. On cervico-vaginal smear examination, the tumor has well confused of atypical repair cell of the endocervix. Recently, we have experienced two cases of glassy cell carcinoma of the uterine cervix, diagnosed on cervico-vaginal smears and confirmed on following histologic sections. The cervico-vaginal smears revealed abundant clusters with well defined boarders. The cell clusters were composed of large tumor cells. The tumor cells had distinct granular cytoplasm and eosinophilic macronucleoli. Characteristic cytologic features of this tumor were discussed in view of differential diagnosis.
