We report a case of trichorrhexis nodosa in a 27-year-old male. Scanning electron microscopic findings reveals those of typical trichorrhexis nodosa nodal swelling of affected hair showed longitudinal fissures and fractures in the cortex. A paintbrush effect was noted at the site of fracture. Simple avoidance of trauma gave some regrowth of hairs.

BACKGROUND: IL-4 is known as a potent stimulating factor and, TNF-α and IFN-γ suppress collagen synthesis of dermal fibroblasts. However, relatively little is known about interaction of these cytokines. OBJECTIVE: The purpose of this study was to evaluate the interactional effect of TNF-α and INF-r for the type I collagen gene expression and promoter activation produced by IL-4. METHODS: Using dermal fibroblasts from the normal skin cultured with three cytokines, IL-4, TNF-α and IFN-γ, we examined Northern blot analysis with each cDNA and assayed CAT activity with human pro a 2(l)collagen(COL1A2)/CAT reporter gene chimeric construct. RESULTS: Compared to the control, treating with IL-4 resulted in prominent elevation of both type I procollagen mRNA levels and prce 2(I) collagen promoter activity. IL-4 with TNF-α suppressed the IL-4 induced elevations, whereas IL-4 with IFN-γ did not reveal the obvious suppression of the elevations produced by IL-4. Fibroolasts treated with IL-4 together with IFN-γ and TNF-α completely abolished the type I procollagen gene expression and the activation of COL1A2 promoter gene elicited by IL-4. CONCLUSION: IL-4 induced enhancement of type I collagen gene expression was synergistically suppressed by TNF-α and IFN-γ on transcriptional level.

Glomus tumor shows histologically characteristic three components of glomus cells, vascular structures, and spindle-shaped smooth muscle cells. It is classified into solid glomus tumor, glomangioma and glomangiomyoma according to relative proportions of components. Glomangiomyoma, the least frequent type of glomus tumor, has its overall histopathologic pattern identical to common solid glomus tumor or glomangioma. In contrast to the foregoing types, however, it has an important number of spindle-shaped smooth muscle cells, which blend with the glomus cells. A 49-year-old woman presented with 2-year history of painful bluish red nodule beneath nail plate of right 4th finger. We made a diagnosis of glomangiomyoma by virtue of routine histopathologic examinations and immunohistochemical stains such as vimentin, smooth muscle actin and desmin.

Benign symmetric lipomatosis is characterized by massive symmetric fat deposition, predominantly in the neck and shoulder girdle ares. We present a case of benign symmetric lipomatosis with alcoholic liver cirrhosis in a 54-year-old man. About two years ago, solitary skin-colored, non-tender swelling on the right upper arm was developed. The lesion had been aggravsted abruptly and rapidly in size and distribution since about one month ago. Histopathologic findings showed completely replaced reticular dermis and invaded subcutaneous tissue by mature fat cells.
