Título : Undifferentiated sarcoma of the sellar region Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2011 Títulos uniformes : Endocrine Pathology Idioma : Inglés (eng) Palabras clave : Undifferentiated sarcoma sella turcica rhabdomyosarcoma immunohistochemistry Resumen : Malignancies lacking specific features of cellular maturation are termed “undifferentiated” and represent 5–10% of all human tumors. They are encountered at a variety of sites but do not, as a rule, arise in the sellar region. A 39-year-old male with a history of testicular seminoma and an unsuccessful biopsy of a third ventricular neoplasm, presented with visual disturbances and memory loss. Light microscopically, the tumor consisted entirely of undifferentiated spindle cells. No germ cell component was noted. An exhaustive immunohistochemical study found immunoreactivity for vimentin and desmin, but for no other myoid markers. Polymerase chain reaction showed no X;18 translocation. Based upon these studies, a diagnosis of “undifferentiated sarcoma” was made. Our case, being highly unusual among reported sellar neoplasms, underscores the difficulties inherent in the differential diagnosis of undifferentiated neoplasms.

Título : Collision tumors of the sella: Craniopharyngioma and silent pituitary adenoma subtype 3: Case report Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, ; Alejandro Daniel Velásquez Urzola, Fecha de publicación : 2009 Títulos uniformes : Endocrine Pathology Idioma : Inglés (eng) Palabras clave : sella turcica collision tumors craniopharyngioma silent pituitary adenoma subtype 3 Resumen : Collision tumors of the sella turcica are rare and consist mainly of more than one type of pituitary adenoma, usually a corticotropin- and a prolactin-producing adenoma. The association of a craniopharyngioma and a pituitary adenoma is rare. Herein, we report the first case of an association between craniopharyngioma and silent pituitary adenoma subtype 3. It involved a 12-year-old boy who underwent a frontal craniotomy with surgical removal of a calcified sellar tumor. Histology revealed an adamantinomatous craniopharyngioma; however, by electron microscopy, there was conclusive evidence of adenoma cells showing the ultrastructural features of silent pituitary adenoma subtype 3. Endocrine and neuroimaging as well as detailed immunohistochemical and ultrastructural studies were undertaken. The literature is also reviewed.
