Erythema annulare centrifugum (EAC), first described by Darier in 1916, is characterized by annular, circinate, gyrate or serpiginous lesions. Although the pathogenesis of EAC is not fully understood, it is considered to be a hypersensitivity reaction to a wide variety of etiological factors, including autoimmune diseases, internal malignancies, drugs, infections, and pregnancy. To the best our knowledge, no case of EAC associated with Candida guilliermondii infection has ever been published in the Korean medical literature, and there have been a few reported cases associated with Candida albicans in other countries. Herein, we report on a rare and interesting case of EAC in a 62-year-old female patient with Candida guilliermondii infection.

The other generalized type of epidermolysis bullosa simplex (EBS) is a genetic blistering skin disease, caused by a mutation of the genes encoding keratin 5 and 14. EBS starts at birth and is characterized by generalized blisters following a minor trauma that heals with hyperpigmentation. A 19-year-old man presented with 19-year history of multiple erythematous vesicles in a herpetiform arrangement on the trunk, axilla, and thigh with post-inflammatory hyper-pigmentations. On light and electron microscopy, the biopsy specimen showed intraepidermal blisters that formed within the basal keratinocyte. The serum from a patient with bullous pemphigoid antibody and laminin 5 antibody showed the linear deposition at the floor of the blister on immunofluorescence mapping study. On the basis of our clinical, microscopic, and immunofluorescence findings, we diagnosed the patient as having a generalized type of EBS. Herein, we report on an interesting case of the other generalized type of EBS.

BACKGROUND: The incidence of cutaneous malignant tumors, especially basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma (MM), has continuously increased in Korea. However, there has been little research into the distribution and incidence of malignant skin tumors in the south-eastern part of Korea. OBJECTIVE: The purpose of this study was to analyze recent trends in incidence and clinical patterns of cutaneous malignant tumors in Busan city and the eastern Gyeongnam Province. METHODS: We reviewed 714 cases of cutaneous malignant tumors that include BCC, SCC, and MM from January 1996 to December 2010 at the Department of Dermatology in Dong-A University Hospital. RESULTS: The average annual incidence of cutaneous malignant tumors among the total number of outpatients was 1.18% and has continuously increased from 0.63% to 1.91% over the last 15 years (1996~2010). In particular, the average annual incidence of BCC and SCC has markedly increased from 0.35% and 0.25% to 0.94% and 0.79%, respectively. The most common cutaneous malignant tumor was BCC (48.32%), followed by SCC (41.18%) and MM (10.50%). The mean age of onset in patients who had been diagnosed with cutaneous malignant tumors was 65.07 years (males: 62.04, females: 67.87). There was a similar incidence between males and females in cutaneous malignant tumors (1:1.08). The most common site of cutaneous malignant tumors was the face (66.25%); the cheek (34.04%) was the most preferential site on the face, followed by the nose (30.23%). CONCLUSION: The incidence of cutaneous malignant tumors has gradually increased in Busan city and the eastern Gyeongnam Province, which was relatively higher than the incidence in other areas. It was thought to be due to the higher proportion of the elderly than in other areas of the country and skin cancer centers in our hospital.

Cryoglobulinemia, first described by Wintrobe and Buell in 1933, is characterized by the presence of serum immunoglobulins that precipitate below 37degrees C and that dissolve on rewarming. Although the actual mechanism of cryoprecipitation and the etiology of cryoglobulinemia remains obscure, it is frequently associated with other systemic diseases, such as hepatitis C virus (HCV) infection, multiple myeloma, Sjogren's syndrome, B cell lymphoma, and systemic lupus erythematosus. No cases of cryoglobulinemia associated with B cell lymphoma have ever been published in the Korean medical literature, and few such cases have been reported in other countries. Herein, we report on a rare and interesting case of cryoglobulinemia developed in a patient with gastric diffuse large B cell lymphoma.

Chilblain lupus erythematosus (LE) is a rare, chronic form of cutaneous LE (CLE), which presents mostly in women as erythematous to violaceous plaques on the acral areas and face, precipitated by cold and damp climates. It may be accompanied by discoid LE (DLE) lesions or other forms of CLE. Up to 20% of patients develop systemic LE (SLE). Although two missense mutations in TREX1, encoding the 3'-5' repair exonuclease 1, were described in familial chilblain LE, the pathogenesis of sporadic chilblain LE remains unknown. To our knowledge, there are a few reports of chilblain LE in the Korean dermatologic literature. Herein, we present a rare and interesting case of sporadic chilblain LE in 71-year-old man and review the Korean literatures.
