O linfoma/leucemia de células T do adulto (ATLL) é um tipo raro de linfoma causado pelo vírus T-linfotrópico humano tipo I (HTLV-1). O quadro clínico inclui lesões de pele, adenomegalias, mielopatia/paraparesia espástica tropical, uveíte, doença oftalmológica, leucocitose com linfocitose e linfócitos atípicos. O objetivo deste estudo foi relatar o caso de uma paciente com ATLL, agricultora, com leucocitose, linfocitose, eritema ocular bilateral, linfadenopatia cervical, sem visceromegalias abdominais e com marcadores positivos para linfócitos T (CD45, CD2, CD3, CD5, CD4 e CD25). Embora a ATLL seja uma doença rara, a demora no seu diagnóstico pode levar a sérias complicações e ocasionar a morte do paciente.
