Dermatophytosis of the palm of the hands (tinea manus) tends to involve one hand. We encountered a case of bilateral tinea manus in a patient with type 1 diabetes mellitus and bilateral tinea pedis. A 57-year-old man presented for evaluation of hyperkeratotic lesions on both his palms and soles. Skin examination revealed hyperkeratotic scaly lesions on the palmar surfaces of his hands and plantar surfaces of his feet. Yellow discoloration and thickening were observed on both his nails. Fasting venous plasma glucose concentration and hemoglobin A1c levels were 332 mg/dL and 7.5%, respectively. Fungus cultures revealed white colonies with brown color on the reverse side in a 14-day incubation period. Trichophyton rubrum infection was identified using polymerase chain reaction with amplified internal transcribed spacer regions. He was treated with oral fluconazole (150 mg/week) and topical flutrimazole spray. In addition, we examined the frequency of 77 superficial fungal hand infections (age, sex, seasonal distributions and coexisting fungal infections) among patients who visited the dermatologic clinic of Chonbuk University Hospital between January 1997 and December 2016.
ABSTRACT
It is well recognized that the deposition of mucin occurs in areas of eruption in patients with lupus erythematosus. However, nodular cutaneous mucinosis is regarded as a rare distinctive cutaneous mucinosis in which the mucin deposition occurs in areas other than the sites of eruption in patients with systemic lupus erythematosus and manifests as a clinically specific lesion. Although several cases have been described in the literature, there have been only two reported cases in Korean literature. Thus, we report an interesting case of nodular cutaneous mucinosis that occurred in a young man. A 16-year-old man visited our clinic presenting with multiple soft subcutaneous nodules on his back for 6 months. He denied any other symptoms. Histological examination showed diffuse mucin deposition throughout the superficial and mid-reticular dermis. The abnormal laboratory values were as follows: a positive antinuclear antibody, increased anti-dsDNA, and reduced WBC count and C3 levels. He was diagnosed with nodular cutaneous mucinosis with systemic lupus erythematosus and treated with oral hydroxychloroquine and methylprednisolone. Our report is of interest owing to the rarity of developing nodular cutaneous mucinosis as an initial presentation of systemic lupus erythematosus.

Angiomyxolipoma is a recently described and rare variant of lipoma that is characterized by the proliferation of adipose tissue with a myxoid stroma and multiple thick and thin-walled blood vessels. A 51-year-old man presented with a tender subcutaneous nodule on his right arm. The tumor was completely removed by excisional biopsy, and the histopathologic features revealed a thin fibrous capsule with incomplete fibrous septa extending into the lesion, dividing it into lobules of different sizes. The fat cells were mature, with a single vacuole and an eccentric nucleus. The vascular component consisted of groups of capillaries and occasional vessels of larger caliber. Erythrocytes were present within the lumen, and myxoid stroma was found. He was diagnosed as having angiomyxolipoma. Herein, we report a rare case of subcutaneous angiomyxolipoma of the arm. We also review and discuss such cases in the literature.

BACKGROUND: Nowadays in Korea, the diagnosis and treatment of the skin diseases by non-dermatologists are surprisingly frequent, and dermatologists often encounter patients who could not distinguish a non-dermatologist from a dermatologist. Thus, misdiagnoses and complications might increase as well. OBJECTIVE: This study aims to evaluate the awareness and attitudes of patients, who seek treatment for their skin diseases, toward dermatologists and non-dermatologists in Korea. METHODS: Between September and December 2014, a total 221 dermatologic outpatients, who visited Chonbuk National University Hospital, were asked to complete a questionnaire. The questions covered its accordance with their visiting intention, practical ability to differentiate a dermatologist from other specialists, criteria for choosing the clinic for skin conditions, consciousness about cutaneous treatment by dermatologists, and others. RESULTS: The ratio of male to female was 1:1.7, and the mean age was 40.5 (±13.18) years. Even though 34.8% of patients answered that they could distinguish between a dermatologist and a non-dermatologist, only 19.0% of the total patients were able to recognize the signboard of dermatologists. The most common criteria for choosing a clinic was if a dermatologist is present to administer treatment. Most patients did not want to visit a non-dermatologist for both the treatment of skin disease and cosmetic treatment. CONCLUSION: Many patients desiring dermatologic and cosmetic treatments wanted to see dermatologist; however, their ability to distinguish dermatologist from non-dermatologist was found to be very low. We suggest that the medical law in Korea needs to be improved such that the specialists are required to display a symbol issued by their own society on their signboards.

Dermatofibrosarcoma protuberans is a fibrohistiocytic tumor with intermediate malignancy that usually appears in adults. The congenital type is very rare, and only three cases have been reported so far in the Korean literature. A 2-month-old girl presented with a firm reddish-gray nodule on the middle of her back that had been present since birth. Histopathologically, the lesion was composed of fascicles of densely packed uniform spindle cells arranged in a storiform (mat-like) pattern. The cells had hyperchromatic nuclei and rare mitotic figures. On immunohisto-chemistry, the tumor cells were positive for CD34. Based on these findings, we made the diagnosis of congenital dermatofibrosarcoma protuberans. She underwent wide excision, and there was no evidence of recurrence during 24 months of follow-up. Our report is of interest because of the rarity of congenital dermatofibrosarcoma protuberans and its earliest detection reported in Korea.

Basal cell carcinoma, which characteristically develops on sun-exposed areas such as the head and neck, is the most common cutaneous malignancy. The most important risk factor associated with its development is chronic ultraviolet light exposure, and basal cell carcinomas in non-sun-exposed areas are, therefore, rare. In particular, the nipple-areola complex is an extremely rare site for basal cell carcinomas, and only three cases involving this area have been reported in Korea to date. Here, we report the case of a 66-year-old woman with pigmented superficial basal cell carcinoma in the nipple-areola complex. Typical dermoscopic findings were obtained in this case.

Malignant transformation of hidroacanthoma simplex into in situ porocarcinoma, also known as hidroacanthoma simplex with invasive growth, is very rare. Malignant hidroacanthoma simplex generally arises in the elderly and occurs most frequently on the lower extremities and trunk. The gross appearance of the tumor tends to vary, and there are nodular lesions or keratotic plaques with or without erosion and/or ulceration. In some cases, it clinically resembles Bowen's disease or seborrheic keratosis. Histopathologically, the tumor appears similar to hidroacanthoma simplex, but the cells are atypical with hyperchromatic nuclei, and many are in mitosis. Here we report an extremely rare case of malignant hidroacanthoma simplex that occurred on the right knee of an 84-year-old Korean woman.

BACKGROUND: Dermoscopic features may be useful in verifying the clinical diagnosis and increasing the diagnostic accuracy of dermatofibroma. There have been no systematic analyses of the dermoscopic features of dermatofibroma in Koreans or studies regarding the correlation between dermoscopic features and histologic subtypes. OBJECTIVE: To investigate the dermoscopic features of dermatofibroma in Koreans and to explore the relationship between the dermoscopic features and histologic subtypes of dermatofibroma. METHODS: The study included 83 lesions from 61 patients with dermatofibroma. Dermoscopic examination was performed via hand-held polarized dermoscopy at 10x magnification. Images were documented using a digital camera with a 3-fold optical zoom. RESULTS: The main dermoscopic structures were pigment network (63.9%), white scar-like patch (53.0%), and homogeneous area (50.6%). The frequency of homogeneous area (50.6%), scale (50.6%), ring-like structure (36.1%), exophytic papillary structure (7.2%), and telangiectasia (6.0%) was significantly higher, and globule-like structure (20.5%) and erythema (8.4%) was significantly lower in Koreans than in Caucasians (p<0.05). Eleven dermoscopic patterns including a peripheral delicate pigment network and central white scar-like patch (28.9%) and total delicate pigment network (15.7%) were observed and there was no significant difference compared to Caucasians. Seven histologic types were observed; however, the correlation between dermoscopic features and histologic subtypes was not significant. CONCLUSION: The most common pattern of dermatofibroma was pigment network and central white scar-like patch in both Koreans and Caucasians. A correlation between dermoscopic features and histologic subtypes in dermatofibroma was not found. These results may be helpful in clinically diagnosing dermatofibroma, especially in Koreans.

Rippled-pattern sebaceoma, a very rare histologic variant of sebaceoma, manifests as a peculiar arrangement of basaloid cells in linear and parallel rows, resembling Verocay bodies. It represents dermal aggregations composed of small, monomorphous, basaloid, sebaceous germinative cells. It has a tendency to occur in men, with the scalp as the predilection site. To our knowledge, only one case has been reported to date in the Korean dermatologic literature. Here, we report a case of rippled-pattern sebaceoma that appeared as a flesh nodule on the occiput and had been present for 4 years in a 41-year-old man.
