Atomic force microscopy was used to compare the structures of dried, torus-bearing pit membranes from four woody species, three angiosperms and one gymnosperm. Tori of Osmanthus armatus are bipartite consisting of a pustular zone overlying parallel sets of microfibrils that form a peripheral corona. Microfibrils of the corona form radial spokes as they traverse the margo. Margo microfibrils are...

BACKGROUND Palmoplantar pustular psoriasis is often recalcitrant to therapy. Here we evaluated the therapeutic effect of alitretinoin in patients with recalcitrant palmoplantar pustular psoriasis and investigated subsequent immunopathological alterations. METHODS Seven patients with palmoplantar pustular psoriasis were treated with oral alitretinoin 30 mg once daily for 12 weeks. Efficacy was...

The cutaneous manifestations of syphilis are many. Most commonly one sees macular, papular, and papulosquamous lesions. Rarely, except in infants, are the lesions vesicular and only occasionally are they pustular (Pillsbury, Shelley, and Kligman, 1956; Pariser, 1964). The pustular lesions may easily be misdiagnosed unless the clinician is aided by the presence of a persistent primary lesion or ...

Erythema nodosum leprosum is characterised by brightly erythematous tender nodules or plaques usually in bilateral symmetrical distribution. ENL can also present in several atypical presentations like pustular, erythema multiform like, ulcerative, necrotic, panniculitic and bullous forms. Various precipitating factors for ENL include stress, pregnancy, surgery, lactation, menstruation, infectio...

Subcorneal pustular dermatosis is a disease that has coalescent, flaccid, recurrent pustules. We do not know everything about its etiology or pathogenesis; however, its autoimmune mechanism links it with neoplastic or immunologic diseases. First line treatment is dapsone. We describe the case of a classic subcorneal pustular dermatosis in a patient in who we could not use dapsone (sulpha drugs ...

Sir, Annular pustular psoriasis (APP) is a rare form of psoriasis characterized by gyrate, annular lesions with an erythematous, scaly, pustular margin (1). Although usually generalized, in some instances it appears as a localized form (2). We herein report a case of APP localized to the dorsa of feet of a 23year-old woman. She had a 4-year history of similar lesions on the same area, but there...

Sir, Pyoderma gangrenosum (PG) is a sterile, pustular, ulcerative process of unknown cause (1). It is frequently associated with various systemic diseases, including inflammatory bowel disease, arthritis, monoclonal gammopathy, malignant disease (2) and, rarely, Behçet’s disease (3). Four clinical and histological variants have been recognized: ulcerative, pustular, bullous and vegetative. Vege...
