Resumen en ingles
Abstract: An 8-year-old boy was seen with a cutaneous Ki-1 anaplastic,
large cell lymphoma with multiple lesions. Some of the lesions showed
spontaneous regression. During more than seven years of disease no
systemic involvement was observed, but recurrent, self-heal~ngle sions
did appear. Histopathologic examination of five lesions revealed a variety
of findings, from an inflammatory infiltrate to a highly anaplastic pattern.
The neoplastic cells expressed Ki-1 and leukocyte common antigens. UItrastructurally,
those cells showed ruffled indentations. The diffe~ntial
diagnosis includes microvillous malignant lymphoma. The patient has
had a four-year follow-up without relapses.
