RESUMEN
Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital vascular disorder. The skin lesions associated with CMTC include persistent, reticulated vascular patches and telangiectasia, and they are sometimes associated with underlying atrophy and ulceration. The condition is present at birth and tends to improve with age, although some skin lesions remain unchanged throughout life. We encountered two patients with CMTC: a 12-day-old infant and a 21-year-old woman with a history of CMTC since birth. Both patients had localized reticulated purpuric patches with atrophy. During follow-up, although the purpuric patches improved in both patients, there were no changes in the skin atrophy in either patient. Herein, we present these cases showing the changes in the cutaneous features of CMTC over time and demonstrate that CMTC at birth may persist throughout life.

RESUMEN
BACKGROUND: Keratinocytes are the major cells in epidermis, providing barrier components such as cornified cells through the sophisticated differentiation process. In addition, keratinocytes exerts their role as the defense cells via activation of innate immunity. It has been known that pathogen-associated molecular patterns (PAMPs) including double-strand RNA and nucleotides can provoke inflammatory reaction in keratinocytes. OBJECTIVE: The aim of this study is to evaluate the effect of Ampelopsis japonica Makino extract (AE) on PAMPs-induced inflammatory reaction of keratinocytes. METHODS: The effects of AE were determined using poly (I:C)-induced inflammation and imiquimod-induced psoriasiform dermatitis models. RESULTS: In cultured keratinocytes, AE significantly inhibited poly(I:C)-induced expression of inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-8 and tumor necrosis factor-α. AE significantly inhibited poly(I:C)-induced release of caspase-1 active form (p20), and down-regulated nuclear factor-κB signaling pathway. In imiquimod-induced psoriasiform dermatitis model, topical application of AE resulted in significant reduction of epidermal hyperplasia. CONCLUSION: These results suggest that AE may be a potential candidate for the treatment of skin inflammation.

Lipedematous alopecia is a rare condition of unknown etiology characterized by a thick boggy scalp with varying degrees of hair loss. It is usually seen in adult African-American females, and a case in a 9-year-old was the youngest patient reported thus far. We report on the appearance of this condition in two children, a 6-year-old child and a 10-year-old child. Each presented with congenital patchy hair loss on the occipital area and the left temple. A boggy hairless scalp with soft swelling was detected in both patients. Histological examination showed increased thickness of the subcutaneous fat tissue with a decrease in hair follicles. These features were consistent with a diagnosis of lipedematous alopecia. We report two cases of congenital lipedematous alopecia, which has not been reported previously. Although congenital, these distinct clinical features should be kept in mind in the diagnosis of alopecic hair loss.

Ferric carboxymaltose is a non-dextran?iron complex used in patients with iron deficiency. However, iron injections may lead to long-lasting brown discoloration secondary to extravasation at the injection site. We herein report a case involving a patient who developed pigmentation after intravenous iron injection and was successfully treated with combined laser therapy. A 36-year-old woman presented with circumscript pigmentation on her left arm after having undergone intravenous iron injection for the treatment of iron deficiency anemia. Histopathologic examination revealed basal hypermelanosis and dermal infiltration of siderophages. Combined therapy with 1064 nm Nd:YAG laser and 595 nm pulsed dye laser was performed to treat the lesion, and marked improvement was noted after five sessions.
