Bullous pemphigoid (BP) is an inflammatory subepidermal blistering disease associated with an IgG autoimmune response to the hemidesmosomal protein, BP180. Using a passive transfer mouse model, our group has shown previously that antibodies to the murine BP180 (mBP180) ectodomain are capable of triggering a blistering skin disease that closely mimics human BP. In this study, we investigated the...

Inherited skin fragility disorders comprise a group of disorders, mainly designated as epidermolysis bullosa (EB), that are characterised by mechanical induced blistering and erosions of the skin and mucous membranes caused by mutations of gene coding for protein components of the dermal–epidermal junction zone. Patients with EB experience various degrees of recurrent skin blistering, widesprea...

Current therapeutic strategies for genetic skin disorders rely on the complex process of grafting genetically engineered tissue to recipient wound beds. Because fibroblasts synthesize and secrete extracellular matrix, we explored their utility in recessive dystrophic epidermolysis bullosa (RDEB), a blistering disease due to defective extracellular type VII collagen. Intradermal injection of RDE...

In 1937, Siemens described a Dutch family with superficial blistering, flexural hyperkeratosis, and characteristic mauserung appearance. Since then, less than 20 kindreds with this condition have been described in the English dermatologic literature. A 14-year-old boy presented with history of recurrent blistering and peeling of skin since the age of 1 month, predominantly seen over limbs and t...

Dermatitis Herpetiformis is a chronic autoimmune blistering skin condition that often associated with gluten-sensitive enteropathy. The primary lesion of DH an erythematous papule, plaque, or, most commonly, vesicle can be pruritic.

We present a case of 3-year-old Caucasian boy who developed monthly cyclic attacks of skin peeling of the palms and soles over 1.5 years. The skin peeling was associated with hypercalciuria. No mutation was present in TGM5 and CSTA genes, but the typical clinical picture and the biopsy from flaccid blisters on the feet confirmed the acral peeling skin syndrome (APSS). The possible associations ...

We present a rare case of a patient with multiple primary acral lentiginous melanomas of the foot. We would like to highlight the importance of whole-skin examination in all patients, even by the general practitioners, aiming the maximal early detection of acral lentiginous melanomas, considering their rapid progression, early metastatic spread and extremely poor prognosis. It can be extrapolat...

The objective of this study was to evaluate the relation between age and dermatoscopic features of acral nevi. We evaluated 159 dermatoscopic images of melanocytic nevi from 146 individuals filed at the Dermatoscopy Outpatient Clinic of Tokyo Women's Medical University Medical Center East between April 2006 and March 2009. All images of melanocytic lesions on acral volar skin that showed a clea...

Acral angioosteoma cutis is a rare disease first described in 2006 that is characterized by vascular proliferation with ossification at the acral area, and which bears clinical similarity to pyogenic granuloma. However, there is no lobular pattern in the capillary proliferation that is a typical histopathological feature in pyogenic granuloma. Metaplastic cutaneous ossification is associated wi...

Background. Malignant melanoma incidence is increasing dramatically. We report herein a case of the rarest acral lentiginous type. Case Report. A 58-year-old man presented with a melanoma resembling lesion over the sole of his right foot, measuring 15-20 mm in diameter. An excisional biopsy with a narrow (2 mm) margin of surrounding skin was obtained. Histological findings were consistent with ...
