A 24-Year-Old Man Presenting with Lung Metastases from a Primary Retroperitoneal Extragonadal Choriocarcinoma.

BACKGROUND Primary retroperitoneal choriocarcinoma is a rare form of extragonadal germ cell tumor that is highly aggressive and responds poorly to chemoradiation. Extragonadal choriocarcinomas are notoriously challenging to diagnose, and have often progressed to advanced disease by the time of diagnosis. The survival rate for extragonadal choriocarcinoma is approximately 30%, which is much lower than that of extragonadal non-seminomatous germ cell tumors (GCT) in general.

Diagnostic Challenges of Dermatofibrosarcoma Protuberans (DFSP), a Rare Spindle Cell Tumor of Breast.

Dermatofibrosarcoma protuberans (DFSP) is a low-grade, fibroblastic tumor that is rarely seen in the breast with only a few cases reported in the literature. DFSP poses a diagnostic challenge as there is significant cytomorphological overlap with other spindle cell lesions. We report a case of a 42-year-old female who presented with a nodule in the right breast.

Strumal Carcinoid Presenting as Large Pelvic Mass: A Rare Case and Review of Literature.

Strumal carcinoid is an unusual rare ovarian teratoma characterized by the presence of thyroid tissue with a carcinoid tumor. We report a case of a 60-year-old nulliparous woman, who presented with complaints of a decrease in appetite, urinary frequency, and left lower extremity edema. By ultrasound of the abdomen, a large multiloculated cystic lesion occupying almost the entire pelvis and measuring 24 x 14 x 20 cm with internal debris concerning either uterine or ovarian cystic carcinoma was seen.
