Bilateral aggressive malignant granulosa cell tumour with essentially different immunophenotypes in primary and metastatic lesions comprising predominantly sarcomatoid and fibrothecomatous patterns-looking for prognostic markers: A case report.
The differential diagnosis of cellular fibroma versus adult granulosa cell tumor may be problematic, as some granulosa cell tumors have a diffuse growth of cells that are somewhat spindled (so-called sarcomatoid granulosa cell tumor), and only focal hints of epithelial differentiation may be a subtle clue to the diagnosis.
Sin embargo, en el avestruz los foliculos en diferentes estados de desarrollo muestran miofibroblastos de disposicion concentrica (teca) que rodean la capa granulosa. Los miofibroblastos son muy notorios en la envoltura tecal de los foliculos vitelogenicos.

It was important to understand if this herb affected the oocytes or their supporting granulosa cells that are critical for reproduction.
The developmental stages of follicles have been defined previously (2) as: i) primordial (one layer of flattened granulosa cells around the oocyte); ii) transitional (one layer of flattened to cuboidal granulosa cells around the oocyte); iii) primary (a single layer of cuboidal granulosa cells); iv) secondary (two or more layers of cuboidal granulosa cells).
Granulosa cells produce antioxidants to protect oocytes from the detrimental effects of excessive ROS (6).
The different types of sex cord stromal tumours include fibromathecoma, granulosa cell tumour (adult and juvenile, which differentiates into female characteristics), Sertoli-Leydig cell tumour (which differentiates into male characteristics).
