Estimation of Alteration of Peripheral Blood Immune Cells in Patients with Plopecia Areata / 대한피부과학회지

Authors have quantitated the T cell and T subsets(T and T cell) in the per- ipheral blood of 16 patients with alopecia areata and 16 normal healthy controls. The results are as follows: 1. The mean values of the T cell in total patient group(54,6+7.9g) and AAP group(5,3. 1+8. 1%) showed staticstially significant decrease when it compared with the mean value of the control group(64.6+3.6%) respectively(p<0.005). In ATU group the mean value of the T cell(53. 1+8. 1%) also showed decreasing tendency in comparison with that of control. The mean values of the T cell in total patient group(30.9+8. 9%) RIld AAP group(3'l. 5+8. %) showed statistically significant decrease when it compared with the mean value of the control group(42,6+8.9%) respectively(p<0. 005). In ATU group the mean value of the T< cell(28. 7+10. 9%) also showed decreasing tende- ncy in comparison with that of control. 3. The mean values of the Tr, cell in total patient group(6. 1+2. 2%) and AAP group(5.9+2.4%) showed staticstially significant decrease when it compared with the mean value of the control group(7.9+1.3%) respectively(p(p pl, pgp p25) In ATU group the mean value of the T cell(6. 7+0. 9%) also showed decreasing tendency in comparison with that of control. 4. The mean values of the T/T ratio showed no significant difference between the patient groups(total, AAP, ATU) and control group, respectively. Above data showed that defect of T cell and T subsets may be associated with the pathogenesis of alopecia areata.

A Case of Epidermolysis Bullosa Dystrophica / 대한피부과학회지

Epidermolysis bullosa dystrophica(EBD) is a rare, hereditary and chronic mechanobullous disease characterized by blistering and erosions of the skin in response to even minor trauma. A 5-year old girl visited with a complaint of continuous vesicobullous skin eruptions since birth. On examination, bullae, vesicles, atrophic scars, crusts and ero:ions were scattered on whole body. Loss of finger and toe nails, partial syndactyly of all toe webs and milia on dorsa of feet were noticed. We present a case of EBD that seems to be a recessive type considering the absence of family history with histopathologic and electron microscopic findings.

A Case of Xeroderma Pigmentosum / 대한피부과학회지

The role of the immune system in pathogenesis of skin cancer has been attracted increasing attention in recent years. Some limited studies and observations suggest that altered immune status may be a factor in the initiation and growth of cutaneous malignancies. Authors experienced a typical case of xeroderma pigmentosum in a 6 year-old girl, who has been suffered from hyper and hypopigmented macules on sun-exposed area, photophobia and also noted eroded lesion on the lower lip. The biopsy finding of the hyperpigmented macule showed that of freckle and the finding of actinic cheilitis was observed from the specimen of eroded 1esion on the lower lip. We performed immunologic test and obtained some evidences of immunologic defect; such as decreased numbers of total T cells, T-suppressor cell and B cell in our patient.
