    Notes: Background  ERBIN is a binding partner of Erb-B2, an orphan receptor within the Erb-B family critically involved in the regulation of cell growth and differentiation. Although its function remains unclear, ERBIN is thought to affect the polarity of epithelial cells and cell growth via the Ras signalling pathway.Objectives  To examine and compare the tissue distribution and the expression levels of ERBIN and Erb-B2 in normal skin and in cutaneous carcinomas.Methods  Fifteen cases of basal cell carcinoma (BCC), 12 cases of squamous cell carcinoma (SCC) and five cases of keratoacanthoma (KA) were analysed by immunohistochemistry on paraffin-embedded sections using anti-ERBIN and anti-Erb-B2 antibodies.Results  ERBIN and Erb-B2 had a similar distribution in normal human skin. They were primarily localized at the plasma membrane in differentiated keratinocytes and in duct cells from eccrine glands, whereas they were localized diffusely in the cytoplasma of basal keratinocytes. In both SCC and KA the subcellular distribution of ERBIN and Erb-B2 remained unchanged, whereas both proteins were redistributed from the plasma membrane into cytosolic aggregates in BCC.Conclusions  The subcellular localization of ERBIN in normal human skin is similar to that of Erb-B2 and varies with cell differentiation. Based on our findings and on the biological activities of Erb-B2, it is conceivable that disturbed expression or functioning of ERBIN and Erb-B2 is implicated in the development of the malignant phenotype of BCC.

    Notes: Background  The simultaneous occurrence of bullous pemphigoid (BP) and multiple sclerosis (MS), two autoimmune diseases involving the skin and the central nervous system (CNS), respectively, has been described.Objectives  As the BPAG1 gene encodes the epithelial isoform of BP antigen 1 (BPAG1-e), a major autoantigen of BP, as well as additional variants expressed in the neurones of the CNS and peripheral nervous system and in Schwann cells, we tested the hypothesis that products of the BPAG1 gene act as shared autoantigens in both BP and MS.Methods  The reactivity of cerebrospinal fluid (CSF) obtained from 18 patients with MS, 10 patients with other inflammatory CNS diseases and 20 normal controls was assayed by immunoblotting against two recombinant fragments of BPAG1-e encompassing regions that are also found in the neuronal variants BPAG1-n and BPAG1-a.Results  The recombinant protein glutathione-S-transferase (GST)-BPAG1-e1−887 was recognized by five of 18 (27%) CSF samples obtained from patients with MS, two of 10 (20%) samples from patients with other inflammatory neurological diseases and five of 20 (25%) samples from normal controls. Furthermore, two of 18 (11%) CSF samples from patients with MS bound to GST-BPAG1-e1880−2649, whereas none of the samples obtained from patients with other inflammatory neurological diseases or from control subjects showed reactivity.Conclusions  These results raise the possibility that a subset of patients with MS develops an autoantibody response to the neuronal variants of BPAG1. These findings potentially open the avenue of neuronal BPAG1 variants being novel targets of autoantibodies in neurological diseases.

    An unusual form of primary systemic amyloidosis: amyloid elastosis: report of a case treated by haematopoietic cell transplantation (2003)

    Notes: Amyloid elastosis is a rare variant of primary systemic amyloidosis characterized by amyloid deposited around elastic fibres. Only two cases, with pseudoxanthoma elasticum-like features and fatal outcome, have been reported. A 56-year-old woman presented with polyneuropathy and a diffuse plane xanthoma-like eruption. Light and electron microscopy studies revealed deposits of amyloid L encasing either normal-looking or short, fragmented elastic fibres in the dermis in a pattern characteristic of amyloid elastosis. The patient had medullary plasmocytosis with lambda light chain restricted expression and underwent autologous stem cell transplantation, which resulted in progressive regression of mucocutaneous signs and stabilization of the polyneuropathy. Our case extends the spectrum of clinical and histopathological presentations of amyloid elastosis. Haematopoietic cell transplantation might improve outcome in patients with multisystem disease.

    Calcifying panniculitis following subcutaneous injections of nadroparin-calcium in a patient with osteomalacia (2005)

    Notes: Calcifying panniculitis is a rare form of calcinosis cutis belonging to the spectrum of calciphylaxis that has almost invariably been described in patients with severe renal disturbances. We report a patient with osteomalacia without chronic renal failure, who developed calcifying panniculitis following subcutaneous administration of nadroparin-calcium. Light microscopy studies of biopsy specimens revealed multiple foci of microcalcification within the adipose lobules, in the interadipocyte spaces, in connective tissue septa and in the media of small arteries in the subcutis. The patient had an elevated level of intact parathyroid hormone, whereas the calcium-phosphorus product was normal. The lesions slowly resolved upon discontinuation of nadroparin. We conclude that calcifying panniculitis is a rare complication associated with the subcutaneous administration of nadroparin-calcium that may rarely also occur in the absence of renal disturbances. Low molecular weight calcium-containing heparins should probably be used with caution in the presence of hyperparathyroidism.

    Erosive pustular dermatosis of the leg: report of three cases (2002)

    Notes: Summary Erosive pustular dermatosis of the leg is a distinct form of spongiform amicrobial pustulosis. The disorder typically affects the lower limbs of elderly patients presenting with chronic venous insufficiency and stasis dermatitis, and has a chronic course. Three elderly patients with chronic venous ulcers are described, who developed pustules and moist eroded lesions on the leg. The clinical and histological features were typical for erosive pustular dermatosis. The lesions rapidly responded to topical treatment with either tacrolimus or corticosteroids. Of note, this condition was associated with a diverticular disease in two patients, while in another patient an epidermoid carcinoma of the tongue was present. Erosive pustular dermatosis of the leg is an uncommon but distinct skin disorder typically associated with trophic changes of the lower limbs. Our observations raise the question of the relation of erosive pustular dermatosis of the leg with the group of neutrophilic dermatoses. Topical immunotherapy with tacrolimus may constitute a novel therapeutic option for this frequently recalcitrant condition.

    Notes: Background  Bowel-associated dermatosis–arthritis syndrome denotes the occurrence of diarrhoea with arthritis and skin lesions related to bowel disease with or without bowel bypass. In this condition, the histological finding of cutaneous aseptic neutrophilic cell infiltrate is non-specific and common to a wide spectrum of neutrophilic dermatoses, including pyoderma gangrenosum.Observation  We describe a 78-year-old woman with fever, abdominal discomfort and arthralgias, who developed grouped pustular lesions on her shins with histologically spongiform pustule formation. Aetiological assessment disclosed diverticular disease with sigmoid stenosis.Conclusion  Although clinical and histological features in our case fit the diagnosis of bowel-associated dermatosis–arthritis syndrome, they may also correspond to a pustular variant of pyoderma gangrenosum. Our observation raises the question of the nosological classification of bowel-associated dermatosis–arthritis syndrome within the spectrum of neutrophilic diseases.
