BACKGROUND Mucous membrane pemphigoid (MMP), a chronic autoimmune subepithelial blistering disease, is associated with circulating IgG and/or IgA autoantibodies against several basement membrane zone antigens. The heterogeneity of clinical presentation and diversity of target autoantigens have contributed to difficulties in characterizing this condition(More)
Pemphigoid nodularis is a rare clinical variant of pemphigoid characterized by overlapping clinical features of both prurigo nodularis lesions and pemphigoid-like blisters. In pemphigoid nodularis, the immunopathological findings are identical to those of bullous pemphigoid (BP). We describe five patients who presented with the typical clinical phenotype of(More)
These guidelines for management of pemphigus vulgaris have been prepared for dermatologists on behalf of the British Association of Dermatologists. They present evidence-based guidance for treatment, with identification of the strength of evidence available at the time of preparation of the guidelines, and a brief overview of epidemiological aspects,(More)
The optimal timing and extent of neck dissection in the context of chemoradiation for head and neck cancer remains controversial. For some institutions, it is uncertain whether neck dissection should still be performed upfront especially for cystic nodes. For others, neck dissection can be performed after chemoradiation and can be omitted for N1 disease as(More)
BACKGROUND Bullous pemphigoid (BP) is the most common subepidermal immunobullous disease, characterized by circulating IgG autoantibodies targeting BP180 and BP230 hemidesmosomal proteins. Several immunological studies have demonstrated that the membrane proximal noncollagenous domain NC16a of BP180 is the immunodominant region targeted by BP(More)
We report a patient with chronic lymphocytic leukaemia who developed paraneoplastic pemphigus (PNP) soon after the initiation of fludarabine therapy. He presented with severe oral and cutaneous erosions. Initially, he had high titres of circulating autoantibodies as detected by indirect immunofluorescence (IF) on multiple epithelial substrates (normal human(More)
OBJECTIVE Tracheostomy offers significant advantages over endotracheal intubation in patients requiring long-term assisted ventilation. However, in patients who have undergone median sternotomy, it is believed that the danger of microbial contamination and consecutive infection of the sternal wound with microbes from the tracheostomy is high when(More)
Lichen planus pemphigoides (LPP) and pemphigoid nodularis are rare clinical variants of bullous pemphigoid (BP), which are characterized by histological findings of lichen planus (LP) and nodular prurigo, respectively, and the finding of linear deposits of IgG and/or C3 at the basement membrane zone in perilesional skin. In both cases bullae may arise at(More)
Psoriasis is a chronic inflammatory skin disorder which is generally not associated with scarring. We report two patients with long-standing severe anogenital psoriasis, that was associated with loss of the labia minora, thus clinically mimicking the scarring associated with lichen sclerosus. Histopathological finding were however, consistent with psoriasis(More)
BACKGROUND Secondary localized cutaneous amyloidosis is a clinically unapparent phenomenon associated with various cutaneous pathologies, usually tumours of epidermal origin. The amyloid is thought to be derived from keratinocytes. OBJECTIVES To characterize the amyloid deposition observed incidentally within lesional biopsies from three patients with(More)
