However, a ganglioneuroma may become cancerous and spread to other areas, or it may regrow after removal. [citation needed] If the tumor has been present for a long time and has pressed on the spinal cord or caused other symptoms, it may have caused irreversible damage that cannot be corrected with the surgical removal of the tumor.
A pistil typically consists of an expanded basal portion called an ovary, an elongated section called a style and an apical structure called a stigma that receives pollen. The ovary (from Latin ovum, meaning egg) is the enlarged basal portion which contains placentas, ridges of tissue bearing one or more ovules (integumented megasporangia). The ...

Trabeculectomy is the removal of part of the eye's trabecular meshwork as a treatment for glaucoma. Tumorectomy is the surgical removal of a tumor. Turbinectomy is the removal of the turbinate bones in the nasal passage.
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
Tumor of the ovary vary remarkably as they may arise from any of the 3 cell types of the normal ovary. Ovarian tumors are classified according to the histology of the tumor, obtained in a pathology report. Histology dictates many aspects of clinical treatment, management, and prognosis. The most common forms are:
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.
Sex cord–gonadal stromal tumour is a group of tumours derived from the stromal component of the ovary and testis, which comprises the granulosa, thecal cells and fibrocytes. [1] In contrast, the epithelial cells originate from the outer epithelial lining surrounding the gonad while the germ cell tumors arise from the precursor cells of the ...
Oophorectomy (/ ˌ oʊ. ə f ə ˈ r ɛ k t ə m i /; from Greek ᾠοφόρος, ōophóros, 'egg-bearing' and ἐκτομή, ektomḗ, 'a cutting out of'), historically also called ovariotomy, is the surgical removal of an ovary or ovaries.
