Definitions related to lymphomatoid papulosis:
-
A chronic, recurrent cutaneous disorder characterized by the presence of spontaneously regressing papules. The papules are composed of an atypical lymphocytic infiltrate that contains anaplastic CD30-positive T-cells, which are found in type A and diffuse large cell type (type C) lymphomatoid papulosis. In a small number of cases, of type B, the lymphocytic infiltrate is composed of small, cerebriform-like lymphocytes that are often negative for CD30. The majority of cases follow a benign clinical course, but some cases are clonal and may progress to lymphoma. Treatment options include low dose methotrexate and psoralen/UVA (PUVA).NCI ThesaurusU.S. National Cancer Institute, 2021
-
Clinically benign, histologically malignant, recurrent cutaneous T-cell lymphoproliferative disorder characterized by an infiltration of large atypical cells surrounded by inflammatory cells. The atypical cells resemble REED-STERNBERG CELLS of HODGKIN DISEASE or the malignant cells of CUTANEOUS T-CELL LYMPHOMA. In some cases, lymphomatoid papulosis progresses to lymphomatous conditions including MYCOSIS FUNGOIDES; HODGKIN DISEASE; CUTANEOUS T-CELL LYMPHOMA; or ANAPLASTIC LARGE-CELL LYMPHOMA.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021

Lymphomatoid papulosis (LyP) is a rare cutaneous condition characterized by chronic, recurrent, and self-regressing papulonodular skin eruptions. It belongs to the spectrum of primary cutaneous CD30+ lymphoproliferative disorders, along with primary cutaneous anaplastic large cell lymphoma (primary C-ALCL; see this term) with which it shares overlapping clinical and histopathologic features.OrphaNetINSERM, 2021
-
Lymphomatoid papulosis (LyP) is a chronic papulonecrotic or papulonodular skin disease with histologic features suggestive of a malignant lymphoma. The disease is characterized by recurrent crops of pruritic papules at different stages of development that predominantly arise on the trunk and limbs.WebMD, 2019
-
Lymphomatoid papulosis (LyP) is a non-contagious, chronic skin condition characterized by the eruption of recurring, self-healing bumps (lesions) on the skin. The lesions typically begin small and then become larger, and they may bleed or ulcerate before becoming scaly and crusty. They often develop a red-brown color.
