BACKGROUND: Many pigmentary disorders can be manifested as linear streaks of hyperpigmentation, along the Blaschko's line. These include progressive cribriform and zosteriform hyperpigmentation (PCZH) and linear and whorled nevoid hyperpigmentation (LWNH). There have been debates on the universally accepted diagnostic criteria differentiating these disease entities. OBJECTIVE: To determine the clinicopathologic characteristics of hyperpigmentation along the line of Blaschko and to examine the acceptability of PCZH or LWNH criteria as a diagnostic tool for differentiating these diseases. METHODS: A retrospective study was conducted on 13 patients who presented with linear hyperpigmentation along the Blaschko's line. The patients' clinicopathologic characteristics were analyzed and matched with the PCZH/LWNH diagnostic criteria. RESULTS: Age of onset widely ranged from birth to 61 years, but predominantly before the age of 4 years. The male-female ratio was 1:1.2. Trunk was the most common site of involvement. Histologic examination commonly showed a basal layer hyperpigmentation in all patients and pigmentary incontinence was observed in 2 patients. Four patients who satisfied all the diagnostic criteria for PCZH also fulfilled the diagnostic criteria for LWNH, except for the timing of onset. An additional 4 patients satisfied all the diagnostic criteria for LWNH and also fulfilled the diagnostic criteria for PCZH, except for the timing of onset. Excluding the age of onset criteria, the other 3 patients fulfilled both diagnostic criteria for PCZH and LWNH. CONCLUSION: These results demonstrate that PCZH and LWNH should not be considered as a different disease entity and that supports the idea that these are part of the same disease spectrum.

BACKGROUND: Vitiligo is an acquired disorder with destruction of melanocytes and clinically characterized by a progressive clinical course. OBJECTIVE: The significance of various epidemiological factors related to the progression of vitiligo were investigated. METHODS: A clinical study was done on 400 patients who had visited the Vitiligo Clinic of Severance Hospital. Questionaires regarding progression, sex, family history, clinical type, Koebner's isomorphic phenomenon, onset age, and duration of disease were recorded. RESULTS: There was significant progression of vitiligo in patients with family history, nonsegmental type, Koebner's isomorphic phenomenon and long duration. CONCLUSION: Some epidemiologic factors are relevant in predicting the progression of vitiligo.

OBJECTIVES: This study is to explore the frequency of basic symptoms and their relationship with current clinical variables in patients with schizophrenia. METHODS: Eighty-eight schizophrenic patients diagnosed with SCID were interviewed with the Bonn Scale for the Assessment of Basic Symptom (BSABS) and Positive and Negative Syndrome Scale (PANSS). RESULTS: Most frequent basic symptoms were related to abnormalities in perception, cognition and stress reactivity. After controlling age effect, number of admission was correlated negatively with cluster 3 (impaired tolerance to normal stress). Onset age was correlated positively with cluster 3 and cluster 4 (disorders of emotion and affect) and total score. Scores of cluster 1 (thought, language, perception, motor disturbances), and cluster 2 (impaired bodily sensations), and total score of BSABS were significantly lower in paranoid type than residual type of schizophrenia. Scores of cluster 1, cluster 2, and total score of BSABS were correlated positively with subscales for positive and negative symptoms and general psychopathology and total score of PANSS. Cluster 3 was correlated positively only with general psychopathology score and cluster 4 with both positive symptoms and general psychopathology score. CONCLUSION: These findings suggest that certain basic symptoms aggregate significantly in schizophrenia, especially in paranoid type schizophrenia and that systemic evaluation of basic symptoms can be used for the prediction of onset and progress of schizophrenia.

BACKGROUND: Vitiligo is an acquired disease that causes depigmented patches of various sizes. The most widely used method of classification is by the distribution, which is categorized into four types: localized, segmental, universal, and generalized vitiligo. In addition, vitiligo can be divided into segmental and non-segmental, according to its relation to dermatomes. However, few studies have compared the clinical features and prognosis with the symmetry of the vitiligo lesions. OBJECTIVE: We examined 690 vitiligo patients to investigate the clinical significance of symmetry in the distribution of vitiligo lesions. METHODS: The clinical characteristics, distribution, and lesion sizes were investigated in 690 patients who were diagnosed with vitilgo at the Dermatology Department of Chungnam National University Hospital from January 1991 to August 2006. RESULTS: Of the 690 vitiligo patients, 369 (53.3%) had symmetric vitiligo lesions and 321 (46.5%) had asymmetric lesions. Patients with symmetric lesions had an older age of onset, longer duration of disease, wider distribution area, and greater tendency of the lesions to enlarge with time. CONCLUSION: Our clinical classification method, based on the the symmetry of the vitiligo lesions, may help physicians to predict the course and prognosis of the disease. Therefore, the dissemination of new vitiligo lesions in symmetric vitiligo patients should be observed closely.
