  Germ cell tumour
Germ cell tumours are neoplasms derived from germ cells.
In younger women germ cell lesions are more common, thus in patients under the age of 21, 60% of ovarian tumours are of the germ cell type, and up to one-third are malignant.
In males, germ cell tumours occur typically after puberty and are malignant (testicular cancer).

Germ cell tumours of early childhood have biological characteristics which are different than those that occur in adolescents and young adults.
These germ cell tumours are usually located in the sacrum (a triangular-shaped section of fused bone located between the hip bones at the base of the spine) and the coccyx (the fused bones located on the end of the sacrum; also called the tailbone).
Treatment for extracranial germ cell tumour depends upon the location of the tumour, the stage of the tumour, and the type of tumour.

Microscopically, the cells are large and rounded with vesicular nuclei, prominent nucleoli, and abundant cytoplasm.
Because germ cell tumours are frequently of mixed cell type, it is not possible to predict their histology on the basis of these biochemical markers; however, elevated levels of either indicate the presence of a germ cell tumour which is unlikely to be a pure germinoma.
Tumour from other sites may metastasize to the pineal gland in older individuals; their clinical presentation is indistinguishable from that of primary pineal neoplasms.

Germ cell tumors are primarily treated with Cisplatin based chemotherapy and the surgical resection is reserved for residual masses.
Extragonadal germ cell tumours, which are a less common variant (5%), have been hypothesized to arise from migration of the germ cells along the urogenital ridge and most of them being the non-seminomatous variant.2 However, primary mediastinal germ cell tumours remain a relatively rare clinical entity.
Cases of co-existing primary gonadal and extra-gonadal germ cell tumours have also been cited.3 Workup of mediastinal mass consists of CT imaging of the chest, a biochemical assessment of tumour markers and fine needle aspiration or core biopsy.

Testicular germ cell tumours are the most prevalent form of cancer in men aged 15-40 years in western Europe.
Testicular germ cell tumours are particularly susceptible to chemotherapy, and an early diagnosis in people at higher risk because of genetic susceptibility would therefore be beneficial.
It has also been established that the risk to brothers of patients with testicular germ cell tumour of also developing such a tumour is higher (eightfold) than the risk to fathers or sons of patients (fourfold).

According to this theory, the differences in phenotypes expressed by mediastinal germ cell tumors (MGCTs) and gonadal GCTs may be explained by differences in the cellular environment between the gonad and the anterior mediastinum.
The cell carrying this abnormality is relatively protected against apoptotic death because of the oncogenic effect of CCND2, leading to re-initiation of cell cycle and genomic instability.

Although the nodular lesion with atypical mast cells did not appear to be cytologically malignant, the occurrence of atypical mast cells in a nodular lesion but not in a papular lesion might denote progression of the disease as suggested by the emergence of cells positive for p53.
To determine the mechanism of release of large granules from mast cells, we studied by immunohistochemistry the presence of STG I in mast cells in normal human tissues simultaneously with the mast cell markers mast cell tryptase (tryptase) and c-kit.
