THE CLINICAL HETEHOCENEITY OF LYMPHOMATOID I’AI’lILOSIS D.K.M.Chaneand K., Division of Drrmutolog; UniversiQ of Alberta, Edmonton, Alberta, CYlMdC4

l.~mphomatu~d Papulosis is a chronic cutaneous disease

cbaracwrued by mvoluting and recurring papules. plaques, and nodules.

Some ofthrsc ma) progrcss to form vesicular crusted lesions that heal

nltb roarring. On histologic examination. lymphomatoid papulosis is

chamctcrixd by P dense wdge-shaped infiltrate which contains either

lnrgc at!pnd lymphocytes (type A )or small cerebrifomt atypical

I? mphuc?tes (t~pr B). 10.20% ol~cases are associated with lymphoma

ot’n hicb mycosis fungoides. Hodgkin’s disease, lymphocytic

I! mphoma. immunoblastnc lymphoma. anaplastic large-cell lymphoma.

id lethal m,dlinc !@uloma have been reponed. We repo” here five

cases of I? mphomatoid papulosis each of which has had different

clinical presentations. One case presented with scar-like plaques. 2

cases rhoued small scattered papules and grouped lesions. A foutth

patlent had a grnerallzed papulonecrotic eruption. The final case

presented m childhood and after a prolonged interval the patient

de\ eloped leukemia from which he subsequently died.
