A struma ovarii is a rare form of monodermal teratoma that contains mostly thyroid tissue, which leads to hyperthyroidism. Excess iodine consumption notably from algae such as kelp . Thyrotoxicosis can also occur after taking too much thyroid hormone in the form of supplements, such as levothyroxine (a phenomenon known as exogenous ...
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.
Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
Sertoli–Leydig cell tumour is a group of tumors composed of variable proportions of Sertoli cells, Leydig cells, and in the case of intermediate and poorly differentiated neoplasms, primitive gonadal stroma and sometimes heterologous elements.
