BACKGROUND: Generalized pustular psoriasis (GPP) and subcorneal pustular dermatosis (SPD) are clinically and histopathologically difficult to distinguish. There have been no comparative studies examining these two diseases in Korea. OBJECTIVE: To investigate the clinical and histopathological characteristics of GPP and SPD. METHODS: We evaluated the clinical features, laboratory, and histopathological findings in 16 patients with generalized pustular eruption who had visited our hospital over the past 10 years and reviewed the literature. RESULTS: Ten GPP and six SPD patients were included in the study. The mean age at diagnosis was 44.4 years in the GPP group and 50 years in the SPD group. The number of patients with previous personal history of psoriasis vulgaris was 2 (20%) for GPP and 0 (0%) for SPD. The number of patients with history of recent exposure to medications was 1 (10%) and 0 (0%) in the GPP and SPD groups, respectively. Symptoms of fever, arthralgia, and mucosal involvement were reported in 10%, 20%, and 10% of GPP patients and 16.7%, 16.7%, and 0% of SPD patients, respectively. Leukocytosis, eosinophilia, elevated ESR/CRP, and elevated AST/ALT were reported in 25%, 0%, 25%, and 50% of GPP patients and in 20%, 0%, 40%, and 40% of SPD patients, respectively. On histological findings, in the GPP group, spongiosis, and psoriasiform changes including hyperkeratosis/parakeratosis, and rete ridge changes were more apparent than in the SPD group. The mean period of clinical improvement was 32.9 days with 40% recurrence in the GPP group and 38.3 days with 66.7% recurrence in the SPD group. CONCLUSION: Although GPP and SPD exhibit clinical and laboratory findings that are similar and difficult to differentiate, systematic analyses including clinical course, laboratory findings, and histopathological findings are helpful for an accurate differential diagnosis.

BACKGROUND: Skin types vary, making it difficult to identify them at a glance. To effectively understand skin type, analysis based on a questionnaire could be helpful. OBJECTIVE: The purpose of this study was to identify the accuracy and effectiveness of the Baumann skin type questionnaire (BSTQ) compared with an interview with a dermatologic specialist. In addition, we aimed to identify differences in skin type proportions according to age and develop a modified BSTQ. METHODS: Subjects included 202 women (19~64 years of age) who visited the dermatologic clinic of our hospital. They completed both the BSTQ and an interview with a dermatologic specialist. A modified BSTQ was developed by removing similar and racial questions and adjusting grading scores. RESULTS: The agreement between skin type proportions analyzed by the BSTQ and an interview was not reasonable (κ=0.428, 95% confidence interval [CI]: 0.363~0.493). There was a correlation between the proportion of dryness and age (R2=0.029, p<0.05). However, other skin type proportions (sensitivity, pigmentation, and wrinkles) were not significantly correlated with age. The modified BSTQ showed substantial agreement with the BSTQ in skin type proportions (κ=0.691, 95% CI: 0.641~0.740). CONCLUSION: We identified the skin types of Korean women of various ages using the BSTQ and an interview. Furthermore, the modified BSTQ might be helpful for accurately recognizing skin types.

Wolf's isotopic response is defined as the occurrence of a new skin disorder at the site of another unrelated skin disease that has already healed. In most cases of isotopic response, the initial dermatosis is herpes infection, and the most frequent second dermatoses are granulomatous reactions. Various interpretations of this phenomenon have been attempted. However, the exact mechanism has not been identified yet. Herein, we report a case in which the secondary disease was segmental vitiligo that appeared over the same dermatomes of herpes zoster. A 71-year-old woman presented with well-defined, depigmented patches on the left chest and back. She had been diagnosed with herpes zoster on the same dermatomes and treated with an antiviral agent 3 years ago. Histological examination showed decreased basal melanin pigments and melanocytes. Consequently, the patient was diagnosed with segmental vitiligo based on the clinical and histological findings.

Adenolipoma of the skin is an unusual variant of lipoma and this is characterized by the presence of normal eccrine sweat glands within a lipoma. This morphologically distinct variant is a rare lesion with a predilection for the thigh. We report here on a case of adenolipoma and we review the relevant medical literature.

Angioleiomyoma is a deep dermal or subcutaneous, benign tumor that originates from the vascular smooth muscle. It commonly presents between the third and sixth decades of life and it has a female preponderance. It mainly develops on the limbs and especially the lower legs. We experienced a case of angioleiomyoma that occurred on the chin, and this clinically mimicked hemangioma.

BACKGROUND: Making the cytologic differentiation between benign and malignant effusions can be difficult. Because promoter hypermethylation of tumor suppressor genes is a frequent epigenetic event in many human cancers, it could serve as a marker for the diagnosis of cancer. The aim of this study was to investigate the feasibility of detecting promoter hypermethylation as a diagnostic tool with using liquid-based cytology samples for differentiating between malignant and benign effusions. METHODS: A multiplex, nested, methylation-specific polymerase chain reaction analysis was used to examine promoter methylation of 4 genes (retinoic acid receptor-beta, [RAR-beta], adenomatous polyposis coli [APC], Twist and high in normal-1 [HIN-1]) in malignant (n = 85) and benign (n = 31) liquid-based cytology samples. RESULTS: The frequencies of hypermethylation of RAR-beta, APC, Twist and HIN-1 were significantly higher in the malignant effusions than in the benign effusions (p < 0.001 for each). On the receiver-operating characteristic analysis, the area under the curve (AUC) for APC was the greatest. The AUC for the best two-gene combination (APC/HIN-1) was not statistically different from the AUC for the best individual tumor suppressor gene (APC). CONCLUSIONS: This study suggests that promoter methylation analysis on residual liquid-based effusion samples may be a feasible approach to detect malignant effusions, and that APC is the best marker for differentiating between malignant and benign effusions.

Sebaceous carcinoma (SC) is a slow-growing, locally aggressive tumor with the high potency of metastatic spread. This neoplasm frequently arises from the sebaceous glands of the eyelid and exceptionally from extraocular sites. Approximately one-quarter of all reported cases of SC are extraocular. We observed a 42-year-old woman with an crusted erythematous to brownish plaque on her scalp. The biopsy specimen showed that multiple lobules were composed of foamy-cytoplasmic cells and sebocytes which show pleomorphism and atypia. For the immunohistochemistry, abundant tumor cells (with the expressions of epithelial membrane antigens and cytokeratin) were found within the masses. We present here a case of SC of the scalp arising from a previous lesion clinically compatible with a nevus sebaceous.

BACKGROUND: Keloid is one of the most frustrating clinical problems in wound healing. There are numerous treatments for keloids such as surgical excision, steroid injection, radiation therapy, laser, silicone gel application and so on. Surgical excision of a keloid is generally not accepted as a first treatment of choice. However, there have been many reports of successful cosmetic results from specialized surgical treatments such as intra-lesional/intra- marginal excision with or without post surgical adjuvant treatments. OBJECTIVE: The aims of this study areto evaluate the effectiveness of intralesional excision of keloids, the optimal surgical conditions and the proper adjuvant therapy after surgery. METHODS: We analyzed the medical records and clinical photographs of 20 patients who underwent intra-lesional excision of their keloids and who had regular follow-ups for at least for 3 months. The clinical outcomes were assessed by three independent physicians based on their interpretation of the photographs before and after surgery with using a global assessment 5 point scale that ranged from bad, poor, fair and good to excellent. RESULTS: General surgical outcomes after intra-lesional excision: the average improvement score was 4.05 after intra-lesional excision and adjuvant therapy. The average improvement score after intra-lesional excision was 4.71 for ear keloids and 2.83 for keloids in other areas (p=0.000). The average improvement score after intra-lesional excision was 5 for earlobe keloids and 4.42 for ear-helix keloids (p=0.014). The average improvement score was 3.92 for the steroid intra-lesional injection and topical silicone gel combination treatment group after intra-lesional excision and the average improvement score was 4.29 for the single topical silicone gel treatment group (p=0.858). CONCLUSION: Although surgery is not a first treatment of choice for the management of keloids, large recalcitrant keloids need massive surgical removal for faster clinical results. In this study, we found that surgery, and especially intra-lesional excision, is not an absolute contraindication for treating keloids and this is sometimes considered as the first treatment of choice, and especially for ear keloids. However, a more careful surgical approach is necessary for the case of keloids that develop in other areas. Further studies about the optimal surgical indications for keloids and the recommended adjuvant therapy after surgery are necessary.
