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.

Neurilemmomatosis is a clinical entity clearly distinguished from neurofibromatosis of von Recklinghausen's disease, and characteristically consists of multiple, cutaneuos neurilemmomas, central nervous system tumors, and neurologic disorders. A 52-year-old man, with multiple spinal cord neurilemmomas and unilateral acoutic neurilemmoma, presented with multiple subcutaneous nodules on the flexor parts of the extremities. Histologically, it was diagnosed as neurilemmoma. We report a case of neurilemmomatosis associated with CNS tumors.

Dermatofibroma is a common benign cutaneous tumor that usually appears as a slowly growing firm nodule. Polypoid nodular dermatofibroma is one of special variants of dermatofibroma that can be rarely encountered. We reported an unusual case of polypoid dermatofibroma occurring on the right calf in a 34-year old korean male. The lesion was a red to brownish colored, rounded, hard protuberant tumor with short pedicle, measuring 2x2x1.5cm. Excised tumor showed a well- demarcated dermal lesion localized in the protruded area, and dense proliferation of fibroblasts.
