Steatocystoma simplex is a rare benign cutaneous cyst that is thought to be a circumscribed malformation arising from the pilosebaceous duct junction. Reports describing steatocystoma simplex are scarce and many issues remain to be clarified, including frequency and age distribution. Steatocystoma simplex is generally considered to be a solitary,(More)
BACKGROUND Many case reports have described the coexistence of autoimmune bullous diseases (AIBDs) and psoriasis. Among them, anti-laminin γ1 (p200) pemphigoid is the best known. OBJECTIVES We sought to characterize patients with AIBDs and psoriasis and to investigate common AIBDs occurring in these patients. METHODS This retrospective study included(More)
BACKGROUND Despite the established pathogenic role of anti-desmoglein (Dsg) antibodies in classical pemphigus, the significance of autoantibodies to another desmosomal cadherin, desmocollin (Dsc) is at present unknown. No consistent immunoassay for immunoglobulin (Ig) G autoantibodies to Dscs has been developed. OBJECTIVES The aim of this study was to(More)
crusted scabies, for which combination therapy of up to seven courses of ivermectin with topical scabicides is recommended. Nail involvement is another cause of recalcitrance, and combined application of topical scabicides with keratolytic agent is recommended. The favorable tissue accessibility contributes to the scabicid concentration of ivermectin on the(More)
IMPORTANCE Linear IgA/IgG bullous dermatosis (LAGBD) is a relatively rare autoimmune bullous disease characterized by both IgA and IgG antibodies to epidermal basement membrane zone. The heterogeneity and pathogenesis of the LAGBD autoantigens have not been fully elucidated. OBSERVATIONS We report 3 Japanese cases of LAGBD (ages 81, 88, and 64 years; 1(More)
BACKGROUND Chemotherapy-induced alopecia (CIA) has a devastating cosmetic effect, especially in the young. Recent data indicate that two major basement membrane components (laminin-332 and -511) of the skin have opposing effects on hair growth. OBJECTIVE In this study, we examined the role and localization of laminin-332 and -511 in CIA. METHODS We(More)
BACKGROUND The nevus of Ota is usually characterized by small, flat, unilateral, blue-black or gray-brown spots occurring on skin innervated by the first or second branch of the trigeminal nerve. It comprises dermal melanocytes, presumably arising due to the dermal arrest of cells migrating from the neural crest. Nevus of Ota is 3-5 times more common in(More)
Both anti-laminin γ1 pemphigoid and bullous pemphigoid are autoimmune subepidermal blistering diseases. The former is rare and characterized by autoantibodies to laminin γ1, a 200-kDa dermal protein, while the latter is common among the elderly and characterized by autoantibodies to BP180 and BP230, both of which are hemidesmosomal proteins. We experienced(More)
A number of cases of psoriasis vulgaris developing bullous skin lesions have been diagnosed as either bullous pemphigoid with antibodies to the 180-kDa bullous pemphigoid antigen (BP180) non-collagenous 16a (NC16a) domain or anti-laminin-γ1 (p200) pemphigoid. We report a case of subepidermal bullous disease with psoriasis vulgaris, showing antibodies to(More)
