The purpose of this pilot study was to evaluate the acute gastrointestinal morbidity of adjuvant radiotherapy (RT) for Stage I seminoma of the testis. Ten Stage I patients receiving para-aortic and ipsilateral pelvic nodal (dog-leg) RT provided a toxicity baseline (group A). Twenty Stage I patients,
We report a case of a mediastinal seminoma occurring 19 months after the resolution of a pineal germinoma. A 15-year-old boy with headaches and visual changes was diagnosed with a pineal germinoma by biopsy and mildly elevated beta-human chorionic gonadatropin (beta-HCG) in serum and cerebral spinal
The differential diagnosis of retroperito-neal tumors includes lymphoid, germ cell, and neurogenic tumors such as paraganglioma. Paragangliomas are rare neuroendocrine tumors of the autonomic nervous system, which may secrete catecholamines and their metabolites. Clinical features A 21-year-old man presented with headache, hypotonia, hypothermia, and somnolence, deteriorating to a Glasgow Coma Scale score of 3 within days. Hormonal testing revealed panhypopituitarism. His cerebral MRI showed a gadolinium-enhancing lesion in the pituitary gland with adjacent changes to the
It is well established that Down's syndrome exhibits a predisposition to development of leukemia, however, association between aplastic anemia and Down's syndrome is exceptional. Herein, we describe a case of aplastic anemia occurring in Down's syndrome following post-transplant lymphoproliferative
Primary extragonadal malignant germ cell tumors (EMGCTs) are rare and characterized by the location in the midline of the body, including mediastinum, CNS, retroperitoneum and coccyx. EMGCTs present with different clinical and biologic characteristics in different tumor locations. Accurately
BACKGROUND
Testicular seminomas are well known to regress spontaneously at a higher incidence than other tumors. To date, there have been no reports of spontaneous regression of an intracranial germinoma, although these tumors are histologically identical to testicular seminomas.
METHODS
The authors
The authors report a case in which a germinoma in the pineal body displayed spontaneous regression after placement of a ventriculoperitoneal (VP) shunt. Spontaneous regression of malignant tumors is extremely rare, occurring in only one of 60,000 to 100,000 patients. Although in rare cases
