Germ Cell Tumors

Immunohistochemical analysis revealed a Cytokeratin (CK) 7-negative/CK19-positive immunophenotype and moderate hCG expression (++). In postpartum patients with unexplained β-hCG elevation unrelated to pregnancy, ectopic β-hCG-secreting tumors, such as ICC, should be considered in the differential diagnosis after exclusion of trophoblastic and germ cell neoplasms, particularly when accompanied by elevated carbohydrate antigen 19-9 levels.

These findings raise suspicion for Lynch syndrome. This case is interesting because seminoma and colorectal cancer were both identified in a patient with features suggestive of a hereditary cancer syndrome.

miR-371a-3p and cfDNA provide independent information in TGCT, miR-371a-3p being associated with the active disease presence, while total cfDNA levels are increased during the active treatment, reflecting different biology and dynamics of the two circulating biomarkers. These findings have implications for future studies on disease monitoring in TGCT. The sensitivity of miR-371a-3p detection in this real practice cohort is lower than reported previously, suggesting assay standardization and clinical studies setting are warranted before miR-371a-3p implementation into clinical practice.

Despite the generally poor prognosis for GCTs in this demographic, early detection and treatment can lead to favourable outcomes. This report details a case of a 58-year-old woman with a stage 1 mixed GCT who underwent extensive surgery without chemotherapy and has remained tumour-free for 24 months, attributing her good prognosis to the low stage and early intervention, along with the YST component.

This case underscores the importance of considering germ cell tumors in the differential diagnosis of hemorrhagic brain lesions, particularly in young males. Early surgical intervention, combined with systemic chemotherapy, can lead to favorable neurological and oncologic outcomes even in such rare and aggressive presentations.

The median time to progression was 7 months (range 2-16.5 months). The existence of a parallel relationship between the lesion and the ipsilateral inguinal region, as well as the vascular ball sign, is helpful in differentiating testicular ERMS from testicular seminoma.

The presence of a mature teratoma of ovary and late reproductive age explains the morpho-functional changes in the endometrium and receptivity disorders at the preoperative stage.

CSF-PLAP using an 8 pg/mL cutoff demonstrates high diagnostic accuracy for intracranial germinoma. Recognition of potential false-positive results and consideration of sampling site may further improve clinical interpretation of CSF-PLAP measurements.

Delayed diagnosis due to occupational neglect allowed the tumor to reach an exceptional size. Although causal associations remain to be established, preventive strategies that reduce exposure to environmental carcinogens, address occupational stress, ensure adequate sleep, and promote routine scrotal self-examination and timely medical consultation may be considered on general health grounds.

Isolated CA19-9 elevation may be associated with rare primary diaphragmatic teratomas. Furthermore, concurrent laparoscopic hiatal reconstruction (e.g., Nissen fundoplication) provides an excellent, structurally sound functional cure for large tumors intimately adhering to the diaphragmatic crus.

The pathological findings were consistent with pineal region choriocarcinoma. The patient's serum β-HCG level decreased to <0.1 mIU/mL one year after surgery, and the child remained in good condition without recurrence during the 2-year follow-up.
