BACKGROUND: The relationship and differentiation among various dendritic cells of the dermis are unclear. Recently it has hecome possible to identify different subpopulat,ions of dermal dendritic cells using anti-CD34 and anti-factor XIIIa antibodies. OBJECTIVE: To elucidate which cell types the fibrous dermal turnors consist of we compared the staining patterns of these antibodies as well as of anti-Mac 387 antibody which are labeled as inflammatory cells of the monocyte-macrophage lineage. METHODS: Tumors studied included dermatofibrosarcoma protuberans(DFSP, n=2), dermato-fibroma(n=22), neurofibroma, n=27), acrochordon(n=15), keloid, hypertrophic scar(n=10), juvenile xanthogranuloma(n=1, and malignant fibrous histiocytoma (MFH, n=1). We performed immunoperoxidase staining(AUSC technique) with polyclonal anti FXIIIa antibody, monoclonal anti-CD34 antibody, and monoclonal anti-Mac 387 antibody on the formalin-fixed-paraffin-embedded tissue specimens of these fibrous tumors. The intensity of staining was graded as negative, weakly staining, or strongly stainiring. RESULTS: FXIIIa reactivity was strongly present in dendritic and spindle-shaped cells of all dermatofibromas and some nurofibromas(11 of 27 specimens), but absent from the other fibrous tumors. Among these tumors, one of the two DFSPs was uniquely expressed CD34. Dendritic and spindle-shaped cells within tiese tumors were MAC 387 negative. In inflammatory conditions, variable numbers of MAC 38 positive cells were observed, corresponding to histiocytes and mac-rophages, but the labeling of ipithelioid cells and multinucleated foreign body giant cells were variable. CONCLUSION: The findings of significant numbers of FXIIIa positive cells in dermal fibrous tumors studied suggest that thet may be diagnostic utility associated with the use of this antit)ody. In addition, CD 34 expression by the tumor cells can be an extremely useful marker in establishing a definitive diagnosis of IFSP.

Elephantiasis nostras, the result of recurrent skin infection or chronic lymphedema is characterized by marked skin fibrosis and massive enlargement of a body part. We present a case of elephantiasis nostras due to chronic recurrent erysipelas which affected the lower extremities in a 62-year-old man. The patient had had persisting non-pitting edema, and tender multiple verrucous brownish plaques and nodules on both lower legs for 1 year. On histological examination, there was hyperkeratosis and papilomatosis in the epidermis, fibroplasia, dilated thick walled venules and collagen fibers oriented vertical to the skin surface, and hyperplasia of eccrine ducts in the dermis.

Reflex sympathetic dystrophy(RSD) defines as a chronic pain syndrome with sympathetic manifestations that afflicts individuals who haute suffered a trauma to the hand. Persistent pain and dysfunctions of the hand are frequently overlooked by the surgeons. The exact pathophysiology of RSD is not known but severity of injury and prolonged immobilization of the joints are considered as resonable causes on the retrospective studies. The diagnosis of reflex sympathetic dystrophy is based on clinical manifestations, simple X-ray and three-phase bone scan. Confirmative diagnosis absolutely depends on the presence of a diffusely abnormal pattern of uptake in phase III in a patient haying pain with underlying cause and strong clinical signs of sympathetic overactivities. As with most disease processes, early diagnosis and treatment is a goal of management of RSD. Surgical restoration of anatomical structures such as tendon, nerve and joint goes ahead of any kind of procedures and it made the VAS pain score decrease from 7.8 to 3.4 in 16 patients. Also, decrease of pain could be achievable with sympathetic or stellate ganglion block with steroid medication. Active physical therapy after surgery is also verb helpful to functional recovery of the hands. Once the appropriate diagnosis is made, combined therapy composed of surgical restoration of anatomical structure, physiotherapy and steroid medication with sympathetic block will be free from pain and produce early functional recovery.

A 6-year-old girl visited us with a 4-week history of inflammatory, pustular, tender patches and plaques on the scalp, and a 3-day history of multiple, erythematous, indurated, tender, subcutaneous nodules on both pretibial areas. A swab was taken from the scalp lesion and colonies of Tiichophyton mentagrophytes grew on culture. The histopathological findings of the leg nodule were consistent with erythema nodosum. The patient was treated with oral itraconazole and deflazacort, combined with topical potassium permanganate solution. Erythema nodosum regressed two weeks later and the kerion of the scalp regressed six weeks after starting the treatment, leaving residual scarring alopecia. The patient was diagnosed as erythema nodosum probably induced by kerion celsi, that has not been reported in the Korean literature.

A 12-year-old girl presented with a 1-week duration of hair loss associated with splitting of the hair ends and whitish dots on the occipital hairs. On microscopic examination, a longitudinal splitting of the hair shaft with reconstitution of the normal hair distal to the fracture, nodular swellings, with the appearance of broomsticks pushed into one another, at the site of whitish swellings, and the flattening and twisting of the hair shaft around the long axis were demonstrated. Minor trauma to injury-prone hair is a common cause of hair shaft defects, however the reports with the combined conditions are insufficient in the literature. We describe a patient with central trichoptilosis associated with localized trichorrhexis nodosa and pili torti.
