Widespread Choriocarcinoma Metastases from De-differentiated Gastro-esophageal Junction Primary Adenocarcinoma: A Case Report with Literature Review

ConclusionsChoriocarcinomas can rarely originate outside of the female reproductive tract (non-gestational, primary choriocarcinomas). In the infrequent cases where a gestational origin is clinically unlikely, the differential diagnosis includes a non-gestational primary choriocarcinoma and choriocarcinomatous differentiation in another primary malignancy. Careful correlation with imaging and clinico-pathologic studies is paramount to determining their origin and guiding further clinical treatment.

Publication date: Available online 22 October 2019Source: Seminars in Cancer BiologyAuthor(s): Tamara T. Lah, Metka Novak, Barbara BreznikAbstractBrain, the major organ of the central nervous system controls and processes most of body activities. Therefore, the most aggressive brain tumor – glioblastoma and metastases from other organs to the brain are lethal leaving the patients with very short time of survival. The brain tissue landscape is very different from any other tissues and the specific microenvironment, comprising stem cells niches and blood-brain barrier, significantly influences the low rate of glioblast...

Conclusions The extremely low background uptake in normal brain tissue and consequently high tumor-to-brain ratio make 68Ga-PSMA-11 PET/CT highly promising for diagnosis of recurrent disease in GBM patients. Although PSMA expression in recurrent GBM also opens a potential way for targeted peptide therapy with α/β-emitters as well as for prediction of treatment with antiangiogenic agents, the low tumor-to-liver ratio observed in the majority of patients in this study suggests a limited role of radiolabeled PSMA ligands for targeted radionuclide therapy of recurrent GBM.

Conclusions 18F-FDG PET/CT is useful for diagnosing nonsuspected metastasis before neoadjuvancy in potentially operable AEG. The ΛSUV correlates with pathologic response and is a long-term independent prognostic factor of survival.

Primary leiomyosarcoma of the bronchus is an extremely rare malignant neoplasm. A 29-year-old man presented with persisting cough and sputum over 1 month. Unenhanced and contrast-enhanced chest CT showed a nodular lesion in the main bronchus of the left lower lobe and multiple enlarged lymph nodes in the mediastinum. Preoperative staging 18F-FDG PET/CT scan displayed a hypermetabolic lesion of the known nodule and mild FDG uptake of mediastinal lymph nodes. The histological examination confirmed bronchial leiomyosarcoma and reactive hyperplasia in lymph nodes.

A 57-year-old man, on octreotide treatment for metastatic neuroendocrine tumor pancreas, was referred for whole-body 68Ga-DOTANOC PET/CT scan to evaluate treatment response. PET/CT scan revealed DOTANOC-avid lesion in the head of the pancreas with multiple tracer-avid soft tissue lesions in the liver, bilateral adrenal glands, and periportal lymph nodes. In addition, diffuse intense DOTANOC-avid mural thickening with intraluminal polypoidal mass formation was noted within the stomach causing significant luminal compromise, histopathological examination of which turned out be hypertrophic hypersecretory gastropathy. This ca...

We present the case of a 65-year-old man who complained of painless swelling of the left scrotum for 9 months. Scrotal ultrasonography revealed a mass in the left testis. Serum CA199 and CA242 were significantly elevated. 18F-FDG PET/CT was recommended for identifying potential malignancy and showed several hypermetabolic masses in the pancreas, left testis, and right lung. Resection of left testicular and pancreatic masses and fine-needle biopsy of right pulmonary mass were performed, and subsequent pathology confirmed pancreatic adenocarcinoma metastasizing to the testis and lung.

A 63-year-old man with elevated prostate-specific antigen serum levels and enlarged prostate gland underwent ultrasound-guided transrectal biopsy, which did not reveal any evidence of malignancy. In order to help guidance of repeat biopsy, 68Ga–prostate-specific membrane antigen–targeted ligand PET (PSMA PET/CT) was ordered. PET/CT scan showed no abnormal PSMA expression within the prostate gland. There were, however, multiple PSMA-expressing osteolytic lesions throughout the axial skeleton. Bone lesion biopsy obtained for final workup revealed multiple solitary plasmacytomas with multifocal bone involvement. T...

A 72-year-old man with a history of T1cN0M0 prostate adenocarcinoma and rising prostate-specific antigen underwent a fluciclovine PET/CT scan that showed high uptake in several para-aortic nodes, suspicious for prostate cancer. A right upper lobe single pulmonary nodule (SPN), demonstrated only mild uptake, which raised the suspicion for a lung primary. Subsequent FDG PET/CT showed high uptake in the SPN, revealing poorly differentiated adenocarcinoma at biopsy, but with no abnormal uptake in the para-aortic nodes. This case highlights the complementary potential of fluciclovine and FDG PET in patients with a history of pr...
