Granulosa cell tumours are tumours that arise from granulosa cells.They are estrogen-secreting tumours and present as large, complex, ovarian masses. These tumours are part of the sex cord–gonadal stromal tumour or non-epithelial group of tumours.
A very rare tumour producing both ovarian (granulosa and/or theca) and testicular (Sertoli and/or Leydig) cells or tissues. Typically it consists of adult-type granulosa cells and Sertoli cells, [4] [5] but it has been reported with juvenile-type granulosa cells. [6] It has been reported to occur in the ovary usually, rarely in the testis. [7]
In medicine, Meigs's syndrome, also Meigs syndrome or Demons–Meigs syndrome, is the triad of ascites, pleural effusion, and benign ovarian tumor (ovarian fibroma, fibrothecoma, Brenner tumour, and occasionally granulosa cell tumour). [1] [2] [3] Meigs syndrome resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic ...
In 25% of germ-cell tumors, the cancer is discovered during a routine examination and does not cause symptoms. [32] Diagnosing germ cell tumors may be difficult because the normal menstrual cycle and puberty can cause pain and pelvic symptoms, and a young woman may even believe these symptoms to be those of pregnancy, and not seek treatment due ...
Granular cell tumor is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time. It is also known as Abrikossoff's tumor , [ 1 ] granular cell myoblastoma , [ 1 ] granular cell nerve sheath tumor , [ 1 ] and granular cell schwannoma . [ 1 ]
Cell culture of granulosa cells can be performed in vitro. Plating density (number of cells per volume of culture medium) plays a critical role for the differentiation. A lower plating density makes granulosa cells exhibit estrogen production, while a higher plating density makes them appear as progesterone producing theca lutein cells. [12]
Histologically, there are nests of transitional epithelial cells with longitudinal nuclear grooves (coffee bean nuclei) lying in abundant fibrous stroma. The coffee bean nuclei are the nuclear grooves exceptionally pathognomonic to the sex cord stromal tumour, the ovarian granulosa cell tumour, with the fluid-filled spaces Call–Exner bodies ...
A dysgerminoma is a type of germ cell tumor; [1] it usually is malignant and usually occurs in the ovary.. A tumor of the identical histology but not occurring in the ovary may be described by an alternate name: seminoma in the testis [2] or germinoma in the central nervous system or other parts of the body.
