We describe the clinical and pathologic observation of a 50-year-old man with superficial disseminated porokeratosis who developed a squamous cell carcinoma on the dorsum of his right thumb and Bowens disease on his right upper arm. The tumors were surrounded by lesions of superficial disseminated porokeratosis and were thought to develop from the dysplastic epidermal cells located under the comoid lamellae.

In this study, the feasibility of identification and genotypic differentiation of enteroviruses was investigated by using nested reverse transcription-polymerase chain reaction (nested RT-PCR), single-stranded conformation polymorphism (SSCP), and restriction fragment length polymorphism (RFLP) techniques. Two hundred seventy-four clinical samples were assayed by both nested RT-PCR and tube culture method using MRC-5 and MK cells; 58 (86.6%) out of 67 enterovirus culture-positive samples contained enteroviral RNA. In addition, 114 (55.1%) of 207 samples from patients with suspected enteroviral CNS disease with negative viral cultures were positive by the nested RT-PCR. The nested RT-PCR products were genotyped by the SSCP method and the results were compared with serotypes. We could differentiate 6 subtypes, 3 of which are similar to coxsackievirus B3, B5, echovirus 11, plus 3 other subtypes. RFLP cleaved with Sty I, Bgl I, and Xmn I yielded characteristic patterns for each laboratory strains. This study demonstrates the usefulness of the RT-PCR for the rapid diagnosis of enterovirus infection and the potentials of the SSCP method for differentiation of enterovirus strains.

Ideal results of augmentation mammaplasty consist of symmetry, natural shape, soft feeling and inconspicuous scar. In addition, patient's preferences about size and shape should be included. Static implants could not perfectly satisfy patients' desires for size and shape, but expandable implants enable to change the volume after the operation. From September 2001 to September 2004, 76 patients(150 breasts) underwent breast augmentation using permanent expandable implant. The procedure was unilateral in 2 women and bilateral in 74 women. Age ranged from 19 to 50 years(mean, 29 years). Fifty nine patients underwent simple augmentation mammaplasty, 7 patients were corrected of their severe asymmetry, 2 patients with the congenital breast deformity underwent mammaplasty using this, and 2 patients who had undergone unilateral mastectomy were reconstructed of their breasts using expandable implant. There were no definite complications such as capsular contracture, implant rupture, asymmetry. And there reported little dissatisfaction about the size. The permanent expandable implants might be good alternatives in cases of ordinary breast augmentation as well as tissue deficient patients, asymmetry, congenital anomaly, and breast reconstruction.

PURPOSE: Free nipple graft reduction mammaplasty is a simple and effective way to reduce huge breasts. However, this technique is frequently criticized for producing poor projection and hypopigmentation of the nipple areola complex(NAC). METHODS: Sixty three patients(126 breasts) underwent the procedure from 1998 to 2005. Authors' method is similar with the modified Gradinger's technique except the keyhole pattern. After skin flap closing, the position of NAC is determined considering symmetry. The NAC is initially harvested and then resection of the breast followed, leaving a deepithelized inferior parenchymal pedicle(5 x 5cm). The upper point of inferior pedicle is sutured to the fascia of the pectoralis to produce the upper bulge. The nipple is replaced as a free and composite graft. RESULTS: An average of 823grams of breast tissue per breast was removed. There was no major complications. All grafted nipples showed long lasting projection. And also, all NAC eventually regained their normal color except for 3 patients who needed medical tattoos. The overall results were good and patient satisfactory score was high. CONCLUSION: This useful technique greatly enhances long lasting projection and recovers nipple color.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.
