| lymphomatoid papulosis | Clinically benign, histologically malignant, recurrent cutaneous eruption characterised by an infiltration of large atypical cells surrounded by inflammatory cells. The atypical cells resemble reed-sternberg cells of hodgkin's disease or the malignant cells of cutaneous T-cell lymphoma. In some cases, lymphomatoid papulosis progresses to lymphomatous conditions including mycosis fungoides, hodgkin's disease, cutaneous T-cell lymphoma, or ki-1 lymphoma. (12 Dec 1998) |

| lymphomatosis | Any condition characterised by the occurrence of multiple, widely distributed sites of involvement with lymphoma. Avian lymphomatosis, a group of virus-induced transmissible diseases of chickens and some other birds in which there is lymphoid cell infiltration or formation of lymphomatous tumours in various tissues and organs; the two principal diseases are: 1) the avian leukosis-sarcoma complex-induced lymphoid leukosis, involving the bursa fabricius and various visceral organs, that is associated with viruses of the family Retroviridae; 2) Marek's disease, caused by avian herpesvirus 2 and involving primarily the peripheral nerves and gonads and, to a lesser and more variable extent, other visceral organs, skin, muscle, and the eye. Variability of lesion site prompted other names for avian lymphomatosis, such as big liver disease, ocular lymphomatosis, visceral lymphomatosis neurolymphomatosis gallinarum, and fowl paralysis. Synonym: fowl lymphomatosis. (05 Mar 2000) |
