Experimental Dermatology 2010; 19 : 904–911. Abstract: In the skin, amyloidosis can be found with or without systemic disease. Primary cutaneous amyloidosis defines those amyloidoses restricted to the skin without involvement of other systems. Here, we used conformation‐specific antibodies to characterise both fibrillar and oligomeric amyloid aggregates in the skin from patients with cutaneous amyloidosis. Localised cutaneous amyloidosis with different morphology was reproduced in mice by intra‐dermal (i.d.) and subdermal administration of amyloid‐enhancing factor. Moreover, we demonstrated that conformational antibodies were effective in clearing amyloid deposits caused by localised intra‐lesional injections without the necessity of an immune response. Given the accessibility and amyloid localization in this disease, direct i.d. injections of conformational antibodies could be a convenient and direct method for treatment.
