| follicular antrum | <physiology> The cavity of an ovarian follicle filled with liquor folliculi. (05 Mar 2000) |
|---|---|
| follicular atresia | <physiology> The degeneration and resorption of an ovarian follicle before it reaches maturity and ruptures. (12 Dec 1998) |
| follicular cancer of the thyroid | <oncology, tumour> A cancer of the thyroid gland that occurs with increased frequency in those who have had radiation exposure to the neck. Other risk factors include a family history of thyroid disease and history for goitre. Follicular carcinoma constitutes about 30% of all thyroid cancers. It has a greater rate of recurrence and metastasis than that of papillary carcinoma (the most common form of thyroid cancer). Symptoms include enlargement of the thyroid gland or neck swelling, change in voice, cough (occasionally bloody) and diarrhoea. (12 Nov 1997) |
| follicular carcinomas | Carcinoma's of the thyroid composed of well or poorly differentiated epithelial follicles without papillary formation, which are difficult to distinguish from adenomas; the criteria include blood vessel invasion and the finding of metastases of follicular thyroid tissue in other structures such as cervical lymph nodes and bone; follicular carcinoma's may take up radioactive iodine. (05 Mar 2000) |

| follicular cyst | <physiology> Cyst due to the occlusion of the duct of a follicle or small gland. (12 Dec 1998) |
| follicular cystitis | <urology> Chronic cystitis characterised by small mucosal nodules due to lymphocytic infiltration. (05 Mar 2000) |
| follicular dendritic cell | <pathology> A virus-trapping dendritic cell found in lymph node follicles (germinal centres). See: Germinal Centre and Dendritic Cell. (09 Oct 1997) |
