ABSTRACT

Primary cutaneous anaplastic large-cell lymphoma is part of the spectrum of CD30+ lymphoproliferative cutaneous processes, characterized by single or multifocal nodules that ulcerate, are autoregressive and recurrent. Extracutaneous dissemination may occur, especially to regional lymph nodes. Histology shows a diffuse, non-epidermotropic infiltrate , anaplastic large lymphoid cells of immunohistochemistry CD30+, CD4+, EMA-/+, ALK-, CD15- and TIA1-/+. Prognosis is good and does not depend on lymphatic invasion. Radiotherapy, removal of the lesion and/or low-dose methotrexate are the treatments of choice. The present study reports the case of a 57-year-old-woman presenting Primary cutaneous anaplastic large-cell lymphoma with multifocal lesions. The pacient evolved with pulmonary involvement 7 years later. She showed a good response to the treatment with low-dose methotrexate prescribed weekly.


Linfoma cutâneo primário de grandes células T anaplásicas faz parte do espectro de processos linfoproliferativos cutâneos CD30+ e caracteriza-se por nódulos únicos ou multifocais, ulcerados, autorregressivos e recidivantes. Pode haver disseminação extracutânea, principalmente para linfonodos regionais. O histológico mostra infiltrado difuso, não-epidermotrópico, grandes células linfóides anaplásicas de imunohistoquímica CD30+, CD4+, EMA-/+, ALK-, CD15- e TIA1-/+. O prognóstico é bom e independe da invasão ganglionar. Radioterapia, retirada da lesão e/ou metotrexato em baixas doses são os tratamentos de escolha. Este estudo relata o caso de uma mulher, 57 anos, com Linfoma cutâneo primário de grandes células T com lesões multifocais e que, após 7 anos, evoluiu com acometimento pulmonar. Apresentou boa resposta ao tratamento com metotrexato em baixas doses semanais.
