A 20-year-old man with a primary non-seminomatous mediastinal germ cell tumor (yolk sac tumor and immature teratoma) developed hemophagocytic syndrome (HPS) three months after surgical resection. Around the same time, the patient was found to have bone metastases of the germ cell tumor. No other hereditary or acquired diseases related to HPS were found. The thrombocytopenia was refractory to co...

“Burned out” testicular germ cell tumors are rare, representing involuted primary tumors typically discovered during workup for metastatic disease with associated elevated serum tumor markers. Histologically, a hyalinized scar is seen, often with surrounding intratubular germ cell neoplasia. We report a 24 year-old man who presented with a two-month history of cough, dyspnea, and intermittent t...

Introduction Large cell calcifying Sertoli tumors are exceedingly rare. They most commonly benign, but risks for malignancy include older age, larger size of tumor, and solitary tumors. To the author's knowledge, this is first case reported an incidental large tumor when orchidectomy was performed a separate lesion. Case presentation A 31‐year‐old male presented with painless testicular lump. U...

Unclassified mixed germ cell-sex cord-stromal tumor composed of germ cells and sex cord derivatives is a rare neoplasm. Approximately 10% of such tumors have malignant germ cell components. We report the case of a 28 year-old female with a right adnexal mass measuring 8 cm in greatest dimension, containing areas with both germ cell and sex cord components. The germ cell portion contained multip...

Bone metastasis is a rare entity in germ cell tumor of testis and is a poor prognostic site. It is usually associated with synchronous metastasis at other sites. Till now very few cases of isolated bone metastasis of germ cell tumor of testis have been reported but none have reported scapular metastasis. We are reporting a case of nonseminomatous germ cell tumor of right testis that was operate...
