We present the case of a 68-year-old male with four primary
malignant neoplasms detected both metachronously and synchronously.
He was admitted to our clinic with left upper cervical
and inguinal masses. He had been diagnosed with kidney
cancer five years ago and underwent nephrectomy. He was
treated with hormonotherapy for metastatic prostate adenocarcinoma
for one year. Malignant melanoma was detected
on his left toe, and amputation was done three months ago.
The results of cervical and left inguinal lymph node biopsy
revealed diffuse B large cell lymphoma and metastasis of malignant
melanoma, respectively. R-CHOP regimen was started
as the lymphoma treatment. Pathological assessment of newly
detected lesions in multiple primary cancer cases is important
for the treatment approach.
