Dermoscopy can be useful in differentiating scalp psoriasis from seborrhoeic dermatitis

Background  Psoriasis and seborrhoeic dermatitis are common erythematous‐squamous dermatoses that may present with scaly erythematous patches on the scalp. Owing to the similar clinicopathological features of these dermatoses, their differentiation poses a diagnostic challenge, particularly when the lesions on the scalp are isolated.

Structural correlations between dermoscopic and histopathological features of juvenile xanthogranuloma

Juvenile xanthogranuloma(JXG) is the variant of non‐Langerhans’ cell histiocytosis. The orange‐yellow background coloration with clouds of paler yellow deposits is the most characteristic dermoscopic finding of JXG. Other dermoscopic features include erythematous border, subtle pigment network and white linear streak. The objective of this study was to present the structural correlation between dermoscopic features and histopathological findings of JXG and to find the different dermoscopic features in various stages of JXG. Eleven patients with histologically proven JXG were examined with polarized light dermoscopy. Histopathological findings were assessed and dermoscopic features including setting sun appearance, clouds of paler yellow globules, whitish streak, and branched and linear vessels were evaluated. Among 11 patients, five patients were in early evolutionary stage, four patients in fully developed stage and two in late regressive stage. The setting sun appearance was found in all patients in different stages except one in late regressive stage (90.9%). The clouds of paler yellow globules were present in nine patients (81.8%) and were constant features in fully developed stage and late regressive stage. The whitish streak was present in four patients (36.4%) and telangiectasia in 10 patients (81.8%). The setting sun appearance may hold diagnostic value in early evolutionary stage to fully developed stage, but not in late regressive stage. The clouds of paler yellow globules are more predominant in fully developed stage and late regressive stage. In addition to the use of dermoscopy as an accurate diagnostic tool for differential diagnosis, it could be applied in evaluation of histopathological maturation of JXG.

Tumescent superficial liposuction with curettage for treatment of axillary bromhidrosis

Backgrounds  Axillary bromhidrosis is a common but unpleasant and distressing problem faced by many societies, particularly in Asia, where malodour is reflected as a social handicap. Currently, local surgery is the treatment of choice among various non‐surgical and surgical treatment.

Dermoscopy of subungual haemorrhage: its usefulness in differential diagnosis from nail‐unit melanoma

Background  Subungual haemorrhages are characterized by well‐circumscribed dots or blotches with a red to red–black pigmentation, but some cases can be difficult to distinguish from subungual melanoma by the naked eye alone. Dermoscopy has proven to be a useful, noninvasive tool in the diagnosis of pigmented lesions in the nail; however, few dermoscopic studies of subungual haemorrhages have been reported.

Two Cases of Multiple Giant Pilomatricoma

Pilomatricoma is a skin appendage tumor manifestating as a firm, solitary lesion of the face and upper extremity. It generally measures 0.5 to 3.0 cm in diameter and is typically found in young people. We report a 29‐year‐old male and a 13‐year‐old girl who developed three and two protruding masses, respectively. The size of each tumor was larger than 5 cm. The histologic appearance showed sharply demarcated tumor lobules composed of eosinophilic shadow cells and basaloid cells. We describe two unusual cases of multiple giant pilomatricomas and review the literature, emphasizing the number and size.

Linear congenital smooth muscle hamartoma with follicular spotted appearance.

Congenital smooth muscle hamartoma (CSMH) with follicular spotted appearance is a rare clinical variant of CMSH in which patients have marked perifollicular papules in the patches. A linear distribution of CSMH is also extremely rare. We report a 16‐year‐old Korean girl with this uncommon form of CSMH who had linearly arranged, hyperpigmented lesions with follicular papules extending from the right flank to the right lower leg from birth. Pathological findings, including immunohistochemical stains, were consistent with smooth muscle hamartoma. To date, there are only four reports on this rare, follicular form and one report on the linear form of CSMH in the literature. This paper describes the first combined occurrence of follicular spotted lesions and linear arrangement in CSMH.

Prospective, open-label, comparative study of clindamycin 1 %/benzoyl peroxide 5% gel with adapalene 0.1 % gel in Asian acne patients : efficacy and tolerability

Background  Used as individual agents, topical antibiotics and benzoyl peroxide are known to be effective in treatment of acne. Clindamycin phosphate 1% with benzoyl peroxide 5% (CDP/BPO) is a new combination gel, made by rationale, in that combination drug is more effective than either ingredients used alone. Adapalene 0.1% (ADA) is the third‐generation retinoid, shown to be as effective as other topical retinoid with well tolerability.

Comparative analysis of the use of complementary and alternative medicine by Korean patients with androgenetic alopecia, atopic dermatitis and psoriasis

Background  Complementary and alternative medicine (CAM) is being increasingly used among Koreans with chronic dermatologic diseases, such as androgenetic alopecia (AGA), atopic dermatitis (AD) and psoriasis.
