A Case of Pigmented Spindle Cell Nevus / 대한피부과학회지

Pigmented spindle cell nevus (PSCN) is often interpreted as a Spitz nevus or misdiagnosed as a malignant melanoma. Some authors consider PSCN as a pigmented variant of Spitz nevus, but many dermatologists classify it as a separate disease. We report a case of pigmented spindle cell nevus which occurred in a 4-year-old boy. The lesion was a well-demarcated, 3x3mm sized, black macule on the dorswn part of the 4th finger, left hand. The histopathologic findings of the excisional biopsy specimen revealed the proliferation of uniform, spindle shaped, pigmented melanocytes at the dermoepidermal junction and sharply defined lateral margins. The pathologic features were consistent with PSCN.

A Case of Ecthyma Gangrenosum Associated with Liver Abscess and Renal Abscess / 대한피부과학회지

Ecthyma gangrenosum is usually seen in the immunocompromised patients or in the patients with underlying malignancy. Ecthyma gangrenosum is a rapidly progressing skin infection characterized by edema, hemorrhage, bullae and necrosis. We experienced the case of a 13-month-old male who had ecthyma gangrenosum associated with liver absess and renal abscess. The patient initially presented with skin lesions of multiple well defined central necrotic black colored large erythematous bullae. The multiple liver abscess with hepatomegaly and multifocal pyelonephritis with focal renal abscess revealed by abdominal ultrasonogram and computed tomogram. In the bacterial cultures of skin, urine and liver aspiration fluid, Pseudomonas aeruginosa was grown. The patient had no immune deficiency disease. We report this case with a review of related literatures.

Narrow-band UVB as a Tool of Vitiligo Treatment / 대한피부과학회지

BACKGROUND: Many modalities of treatment for vitiligo have been elucidated and yet the treatment of vitiligo remains to be a challenge. OBJECTIVES: The purpose of this article is to review our results and experiences with narrow-band ultraviolet B phototherapy for vitiligo. METHOD: We studied 9 patients with vitiligo who received narrow band UVB phototherapy for 6 months in our department. This is a retrospective analysis of our experiences and results. RESULTS: Nine patients were able to be evaluated for the purpose of this analysis. Their ages ranged from 6 to 68 years(mean, 18.4 years). Six patients of 9 patients achieved more than 75% repigmentation with a mean of 25 sessions of phototherapy. The remaining three patients had 50%, 40% and 30% repigmentation after 44, 40, and 45 sessions of phototherapy, respectively. Adverse effects were mild. CONCLUSION: Narrow-band UVB is a useful and well-tolerated therapy for vitiligo in comparsion with other therapies.
