Clinical and histopathological study of primary cutaneous macular amyloidosis
Fatima Razvi, A.S. Kumar.  |  | | | Abstract Primary cutaneous amyloidosis often presents with pigmentary dystonias of the skin in the form of asymptomatic reticulate hyperpigmentation or pruritic lichenoid papular lesions. The aim of this study was to evaluate the incidence of primary cutaneous macular amyloidosis and also to find out the possible etiological agents, to correlate their clinical disease with histopathological positivity for amyloid deposition, and to find out the percentage of positive cases by special stains. A total of 24 patients attending dermatology out-patient clinic of Princess Esra Hospital, Hyderabad over a period of 1 year presenting with hyperpigmented skin lesions and clinically diagnosed as macular amyloidosis were taken up for this study. Key words: Cutaneous amyloidosis, Macular amyloidosis, Congo red stain
