RESUMEN
A 28-year-old male with bilateral testicular seminoma underwent bilateral orchiectomy and radiation therapy of the retroperitoneum. After 17 years, he had a retroperitoneal tumor detected, which was removed 7 years later at age 52 because of its progressive enlargement. Due to its partially cystic and partially solid structure, the radiologic findings could not exclude the possibility of regressively altered seminoma metastasis. After radical surgical removal of the tumor, the histopathological and immunohistochemical examination of the tumor revealed ancient schwannoma. These tumors, although unusual, might pose a clinical diagnostic challenge with the risk of undesired overtreatment.
RESUMEN
Nowadays, FNAC is an important diagnostic tool of soft tissue tumors in southeast Asia and India. We can also appreciate recent monographies on this topic authored by Swedish and American cytopathologists. They constantly stress the importance of clinical information and imaging studies. A cytology report should determine the morphological type of tumoral cell population, tumor grade (in two-tiered system) and conclusion providing at least some probable diagnostic options. This approach is documented in two case reports on pleiomorphic liposarcoma and giant cell tumor of tendo sheet.
