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.

WC made a 3.dimensional rcconstmctcd skin m&l
through simultanwus culture of normel human skin
tihrohlasts and kcratinwytcs. In thi\ culture system.
the btmcturc was gradualI) dcstroycd and no lunger
usable as an cxpcrimcntal aystcm about 3 weeks after the stat of culture. Thus wc implanted the 3.
dimcnrional rcconstruacd skin mtticl into SCID mice
Lo maintilin the str~cturc of the model for u longcr
pxiod of time. WC compared morphological changes of the skin m&l bctwccn in vitro cultivation and
trawplantation as a time COUISE study. Tltc strwturc
of tbc skin m&l tmnsplantcd inta the SCID mice
could hc succcssfullg tt&taincd more then 5 weeks
