Cutaneous horn is a clinical term for a circumscribed concial hyperkeratotic mass amounts to at least half of its largest diameter. The number of lesion may be single or multiple. We report herein a cases of penile cutaneous horn in a 22-year-old male. He had dark brownish colored conical shaped protruded mass on the penile shaft for about 2 months. We performed excisional biopsy and curettage. Histopathologic findings showed verruca vulgaris.

In order to elucidate the biological effects of pulsating magnetic field in in vitro culture system we designed a pulsating magnetic apparatus using 120 Hertz, 24 Volt direct current. It can generate 63~225 Gauss in the experimental area of 90 mm petri dish, and has little thermal effect on the culture media in 37.5oC, 5% CO2. Human osteogenic sarcoma (HOS) cells were cultured in the pulsating magnetic field and the nuclear changes of cultured cells were observed routinely by hematoxylin staining, and apoptotic change was detected by ApopTag staining using both peroxidase and fluorescein labelings. Compared to the control group which formed well organized whorling pattern of HOS cell line in 3 days culture, the HOS cells cultured in the pulsating magnetic field for 12 hours or 24 hours grew irregularly and showed increased number of apoptotic cells. When the flow of pulsating magnetic field was interrupted by insertion of strong permanent magnetic bar (1000 Gauss, 5530 mm) beneath the petri dish during in vitro culture, the area of sparse pulsating magnetic field showed active proliferation and aggregation of HOS cells even in 24 hour exposure group. These data suggest that the pulsating magnetic field may play a role in inducing growth retardation and apoptosis of HOS cells. Furthermore, the hazardous effects of pulsating magnetic field can be lessened or nullified by the interruption of pulsating magnetic field with a strong permanent magnetic bar.

Annals of Dermatology 1993;5(1):5-8
BACKGROUND: In the course of the study of keratin expression in the epidermis of nevus sebaceus, several cells in the epidermis of nevus sebaceus were positively stained with CAM 5.2 antibody, which is known to be specific for the lower molecular weight cytokeratin and used as a marker of Merkel cell. OBJECTIVE: This study was intended to verify that CAM 5.2 positive cells found in the epidermis of nevus sebaceus are Merkel cells and to understand the meaning of CAM 5.2 positive j cells in the epidermis of nevus sebaceus. METHODS: The immunohistochemical stainings with CAM 5.2 and antibody to epithelial membrane antigen (EMA) performed on specimens of normal skin, epidermal nevus, nevus sebaceus and some appendage tumors. In order to confirm the nature of CAM 5.2 positive cells, the distribution of those were compared to that of Merkel cells and double labeling with CAM 5.2 and neurofilament was performed. RESULTS: CAM 5.2 positive cells were also found in trichilemmoma developed associated with nevus sebaceus and the epidermis of normal paimoplantar skin. CAM 5.2 positive cells were also stained with antibody to EMA on serial sections cut from the same tissue blocks. The association of CAM 5.2 positive cell and nerve fiber was also demonstrated. CONCLUSION: CAM 5.2 positive cells are seemed to be Merkel cells and their presence in the covering epidermis of nevus sebaceus suggests to the epidermis of nevus sebaceus may not be nevoid proliferation of epidermal keratinocytes.
