ABSTRACT
Perforating disorders are a group of skin disorders that present the characteristic clinical finding of transepidermal elimination. Acquired reactive perforating collagenosis is an uncommon condition characterized by umbilicated hyperkeratotic papules, and in almost all cases, it coexists with other disease conditions, such as diabetes mellitus, renal failure, and malignancies. The pathologic mechanism of this disease remains largely unknown. Here, we describe the case of a 42-year-old man who developed acquired reactive perforating collagenosis after coronary artery bypass graft surgery.

Zosteriform metastasis from malignant melanoma is a rare type of skin metastasis that shows cutaneous lesions including patches, plaques, and nodules along with dermatomes, and thus needs to be distinguished from herpes zoster skin infection. Although some authors have explained the mechanism of zosteriform metastasis, its pathogenesis remains unknown. Herein, we describe an 85-year-old woman with zosteriform metastasis of malignant melanoma arising in a medium-sized congenital melanocytic nevus.

BACKGROUND: Verruca plana is a common viral disease that commonly affects the face. It can autoinoculate or autotransmit, as well as cause many cosmetic problems. Skin care material that had direct contact with the skin of an affected person during a skin care procedure can be a transmission route of verruca plana or a risk factor of autoinoculation of the virus. OBJECTIVE: The goal of this study is to compare skin care behavior between skin care clinics and skin care shops, and the effects on verruca plana transmission. METHODS: Seventy-four patients who visited local dermatology clinics in Daegu from January 2011 to January 2013 were selected randomly, and a questionnaire survey was done. RESULTS: The incidence of verruca plana in patients visiting the clinic to receive skin care was higher than in the normal population. There was a statistically significant correlation between the number of procedures and the incidence of verruca plana in both skin care clinics and skin care shops. Whereas the number of verruca plana cases increased with the increase in the number of procedures in skin care shops, there was no significant correlation between the number of procedures and the incidence of verruca plana in skin care clinics. CONCLUSION: The number of procedures was significantly correlated with the incidence of verruca plana. In persons receiving treatment in skin care shops, the incidence of verruca plana increased with the increase in the number of procedures.

Clear cell SCC is a rare variant of SCC initially reported by Kuo in 1980. A lot of cases of clear cell SCC show intracytoplasmic glycogen deposition and thus need to be distinguished from trichilemmal carcinoma. Although some authors studied the histological features of clear cell SCC, with its limited case reports and the variety of its content, the histopathologic findings of clear cell SCC are still imperfectly known. Herein, we report a case of clear cell SCC with review of literatures for histopathologic findings of clear cell SCC.

Basal cell carcinoma (BCC) is the most frequent skin cancer, generally located in hair-bearing, sunlight exposed areas. BCC usually occurs on the head and neck, but very rarely on the sole. A 45-year-old man visited our department with 1 cm sized erythematous patch and erosion. The lesion has been enlarged over a period of 10 years. Dermoscopic examination showed arborizing vessels and blue-gray blotch. Herein, we report a rare case of BCC of the sole with consideration of its origin, cause and dermoscopic findings.

Bullous systemic lupus erythematosus (bullous SLE) is uncommon; distinctive clinical variant of SLE that is characterized by tense vesicles and bullae filled with fluid that occurs on either erythematous or normal skin. Although bullous SLE can accompany erythematous plaque with annular configuration, urticarial papules, and erythema multiforme (EM)-like lesions initially, there is no report of EM-like lesions as an initial sign of bullous SLE in the Korean literatures. Herein, we describe 31-year-old women with bullous SLE that showed EM-like skin lesions as the initial sign.

Genus Alternaria is a species of dematiaceous fungi that is commonly found in the atmosphere or in the soil. It can cause hypersensitivity pneumonitis, bronchial asthma, or allergic rhinitis in immunocompromised host such as patient with organ transplantation or long-term steroid using patient. It can rarely cause skin infection. Case 1 was a 74-year-old man with well demarcated and elevated erythematous plaque with irregular scattered pustules on his right forearm. Case 2 was a 77-year-old woman with well demarcated elevated erythematous nodules within erythematous patch on her right forearm. In both cases, the lesions started at the senile purpura site. Herein, we report 2 rare cases of Alternaria alternata on senile purpura site to share the experience.

Hypertrichosis is a condition of excessive hair growing in areas of the body where androgen is not predominantly dependent. It has been classified into localized and generalized based on the extent of distribution. Generalized hypertrichosis may occur as part of a syndrome or a metabolic disorder. A 55-month-old girl visited our department with accentuation of thick hairs on her mid-back and face since birth. She was diagnosed as developmental retardation at the age of 10 months. None of her family members had hypertrichosis. No abnormal findings were shown on chromosomal and laboratory studies. Therefore, we diagnosed her as generalized hypertrichosis with developmental delay.

Basal cell carcinoma (BCC) is the most common skin cancer in humans. It usually develops on sun-exposed areas of the head and neck but can occur anywhere on the body. The various clinical features include nodules, ulcers, bleeding, crust, or scale. Thus, it is important to distinguish BCC from other diseases with similar clinical features. The umbilicus is one of the sun-protected sites where BCC rarely develops. Herein, we describe 71-year-old woman with umbilical BCC initially misdiagnosed as pyoderma.

Pemphigus vulgaris is an autoimmune blistering disease that commonly involves the scalp. Lesions of pemphigus vulgaris that persist on the scalp for a long period may be accompanied by tufted hair folliculitis. Only two previous accounts of tufted hair folliculitis developing in a lesion of pemphigus vulgaris have been reported. We report a 51-year-old-man with erosions and clusters of hair on the scalp. The scalp lesion had persisted for about 20 years. A histopathological examination of the skin lesion on the scalp revealed separation of the epidermis and clusters of several adjacent hair follicles. The patient was diagnosed with persistent pemphigus vulgaris of the scalp showing features of tufted hair folliculitis.

Dibucaine hydrochloride is an amide-type local anesthetic and it is well known to be a contact allergen. Although there are some reports of allergic contact dermatitis due to over-the-counter medications containing dibucaine in the foreign literature, there is only one report of it in the Korean literature. We report here on a case of allergic contact dermatitis due to an over-the-counter drug containing dibucaine in a 41-year-old-woman. The patch test with the preparation that she had used and the TRUE(R) test revealed positive reactions to the dibucaine mix and Moscool(R).
