Seminoma is one type of testicular cancer that is believed to originate from the germinal epithelium of the seminiferous tubules.
They produce bulky masses that can be up to ten times the size of a normal testis.
and have been proposed as possible markers.
Peak incidence occurs in the 4th decade of life. Histology shows large cells, clear cytoplasm, distinct cell membranes, and septated arcitecture.
In recent years, these tumors have been shown to have dramatic sensitivity to both radiotherapy
and cytotoxic chemotherapy
. The management of childhood seminoma is similar to that of adult seminoma. Orchidectomy
is required in almost all cases.
Relation to spermatocytic seminoma
are not considered a subtype
of seminoma and unlike other germ cell tumours do not arise from intratubular germ cell neoplasia
