Reactive perforating collagenosis(RPC) is a kind of perforating dermatosis characterized by transepidermal elimination of altered dermal collagen. RPC is classified into two forms; childhood or inherited form, and adulthood or acquired form. Acquired RPC is reported to occur in association with the severe complicated diabetes mellitus, chronic renal failure and other diseases. We describe a 43-year-old Korean woman with atypical acquired RPC associated with uncontrolled diabetes mellitus and severe pruritus. The histopathologic findings of the lesions showed neither transepidermal channel nor cup-shaped epidermal depression. Multiple degenerated collagen bundles arranged vertically and were eliminated through epidermis to the surface individually. Transmission electron microscopic findings showed the same as typical RPC. Skin lesions improved after the insulin subcutaneous injections, UVB phototherapy and antihistamine administration.

Nodular fasciitis represents reactive fibroblastic or myofibroblastic proliferative lesions which may be misdiagnosed as sarcomas due to the rich cellularity, mitotic activity and variant morphologic pattern. It arises in the subcutaneous tissue, skeletal muscles, and fascia. Uncommon clinical and pathological variants of nodular fasciitis, such as intradermal, intravascular, cranial, ossifying, parosteal and proliferative fasciitis, have been described. We present a 23-year-old man with a one year history of a 2x1.5cm sized hard tender nodule on the scalp which is partially depressed at the margin. Histological examination revealed clusters of spindle cells in a myxoid background, chronic inflammatory cells and extravasated red cells in the dermis. Immunohistochemically, the spindle cells showed positivity of vimentin or smooth muscle actin, and negativity of desmin or S-100 protein. The staining results support its myofibroblastic origin. There is no involved bony lesion on the brain computed tomography (CT). Therefore we report a rare case of intradermal fasciitis arising on the scalp.

Authors analyzed the findings of findings of chest radiographs and high-resolution CT(HRCT) of chronic mercury vapor poisoning in 12 patients who were diagnosed by previous working history for mercury-thermometer and high level of mercury in blood and urine. The purpose of this paper is to introduce the HRCT findings of chronic mercury vapor poisoning. Duration of mercury exposure was ranged from 10 to 41 months(mean, 21.8 months). Estimated value of serum mercury was ranged from 3.6 to 8.7µg/dl(mean, 5.3 µg/dl: normal value is less than 0.5µg/dl). Estimated value of mercury in urine was ranged from 104 to 482µg/1(mean, 291.4µg/1: normal value is less than 20µg/1). Chest radiographs showed positive findings such as ground-glass opacities and peribronchial cuffings in only 2 out of 12 patients, but HRCT showed positive findings such as ground-glass opacities in 8 patients, peribronchial cuffings in 7 patients, centrilobular abnormalities in 5 patients, interface sign in 4 patients, interlobular septal thickening with intralobular lines in 2 patients and lobular consolidation in one patient. In conclusion, chest HRCT is superior to chest radiograph to show the pulmonary manifestation of chronic mercury vapor poisoning. In patients with chronic mercury vapor poisoning, HRCT findings of centrilobular distributed ground-glass opacities and peribronchial cuffinges are characteristic.

PURPOSE: The aim of this study was to identify the predictive factors in the early laboratory findings for cardiac sequelae in Kawasaki disease(KD). METHODES: A retrospective review of the records was conducted of all children with KD who were admitted to the Ulsan Dongkang General Hospital, Masan Samsung Hospital, and Gyeongsang National University Hospital between January 1995 and December 1999. We analyzed and compared the early laboratory findings between the patients with and without coronary artery dilatation. RESULTS: A total of 981 patients were divided into two groups : 826 patients(84.3%) with normal coronary artery and 155 patients(15.7%) with coronary artery dilatation. Age and sex were not significantly different between the two groups. The mean serum C-reactive protein(CRP) in the coronary artery dilatation group and in the normal coronary artery group were 5.0 mg/dl(+/-5.3) and 4.1 mg/dl(+/-5.0), respectively, with a significant difference(P<0.05), whereas the other early laboratory findings had no difference between the groups. CONCLUSION: This study shows that the early serum CRP was higher in patients with KD who had coronary artery dilatation than in those with normal coronary artery. There may be a strong possibility of cardiac sequelae at a high level of serum CRP. However, the cut-off value of serum CRP could not be determined for the prediction of cardiac sequelae in patients with KD.

Mixed tumor of the skin, so called chondroid syringoma, is a benign epithelial neoplasm with glandular or ductal differentiation surrounded by myxoid stroma. It is most frequently located on the head and neck and presents as an asymptomatic, firm, subcutaneous nodule. Mixed tumor with follicular, sebaceous and apocrine differentiation is considered as an expression of the common embryologic origin of elements of the folliculo-sebaceous-apocrine unit. We report a case of mixed tumor of the skin with follicular, sebaceous and apocrine differentiation.

Lichen nitidus (LN) is an uncommon chronic inflammatory skin disease composed of numerous, tiny, shiny, flesh-colored papules that are predominantly observed on the chest, abdomen, glans penis and upper extremities. The distribution of LN is most often localized, but in some cases it can become generalized. Because LN tends to be asymptomatic and presents spontaneous resolution within several years, it usually does not require treatment except in symptomatic, persistent and generalized cases. We describe a 28-yr-old man and a 7-yr-old boy with generalized LN where both cases improved with narrow-band ultraviolet B (NB-UVB) phototherapy plus topical steroid ointment. Both patients noted improvement within the first three treatments and showed almost complete resolution after 18 and 20 treatments, respectively. NB-UVB phototherapy may be an effective alternative therapy for the treatment of generalized LN, even for those patients in their childhood.

Spindle cell hemangioendothelioma was first described in 1986 to characterize a particular angiomatous lesion which shows different clinical features, however, it has recently been designated as spindle cell hemangioma (SCH) due to its benign nature. Microscopically, this peculiar vascular tumor consists of cavernous blood vessels intermixed with solid areas predominantly composed of spindle cells, resembling Kaposi sarcoma. A 39-year-old woman presented with a bean-sized, tender, bluish nodule on the pulp of her right thumb. The 1 year old lesion had increased slowly in size over this time. Histologic examination of the lesion showed that it was composed of large irregularly-dilated, thin-walled cavernous blood spaces containing organizing thrombi, numerous red blood cells, and a spindle cell mass which was partially connected with the vessel wall and invaded the stroma. A diagnosis of SCH was made based on histologic and immunohistochemical findings. After the lesion was totally excised, there has been neither recurrence nor occurence of new lesions to date.
