Fine needle aspiration diagnosis of metastatic Leydig cell tumor. Report of a case and review of the literature.

Leydig cell tumors are rare sex cord-stromal tumors that account for less than 1% of all testicular tumors. Less than 10% of these tumors show metastatic malignant behavior. Herein we present a case of metastatic malignant Leydig cell tumor in an iliac lymph node diagnosed on fine-needle aspiration (FNA) in a 70-year-old man.

A Case of Renal Metastasis of Uterine Leiomyosarcoma.

A 49-year-old woman with a distant history of uterine leiomyosarcoma underwent robotic-assisted laparoscopic partial nephrectomy for a 3.5 cm right renal mass, which was presumed to be a primary renal cell carcinoma. Surgical margins were negative, and the histologic analysis confirmed leiomyosarcoma.

Oligometastatic Growing Teratoma Syndrome: A Case for an Aggressive Surgical Approach.

Growing teratoma syndrome is an infrequent presentation of testicular cancer. We present a case of growing teratoma syndrome in a patient who initially presented with clinical stage I nonseminomatous testicular germ cell tumor, who subsequently developed large volume oligometastases to the retroperitoneum, thorax, and thigh. Despite two regimens of chemotherapy, his disease progressed.
