Connective Tissue Sheath

Deep cervical fascia forms a connective tissue sheath around the thyroid gland. Delicate trabeculae and septa penetrate the gland indistinctly dividing the gland into lobes and lobules which in turn composed of follicles.1,2,3 These follicles are structural units of thyroid gland which varies greatly in size and shape.4 The number of follicles varies in different age groups. The study was carried out to see the percentage of area occupied by follicles in the stained section of thyroid glands in different age groups. The collected samples were grouped as A (3.5 – 20yrs), B (21- 40yrs) & C (41 – 78yrs). Percentage of area occupied by follicles was (58.55±10.72) in group A, (63.79±12.35) in group B + (63.39±8.29) in group C.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13981 Update Dent.

Abstract We report a case of multiple lymphoepithelial cysts of the thyroid gland in a patient with severe chronic lymphocytic thyroiditis. Lymphoepithelial cysts of the thyroid gland are rare lesions that are histologically similar to branchial cleft cysts found in the lateral neck. The cysts have an epithelial lining that is usually stratified squamous epithelium but may be focally respiratory-type epithelium. Abundant lymphoid tissue is present beneath the epithelium, and lymphoid follicles with reactive germinal centers are common features in the walls of the cysts. Because of their similarity to branchial cleft cysts and the presence of intrathyroidal branchiae-derived structures such as thymus and parathyroid gland tissue in the vicinity of some cysts, lymphoepithelial cysts of the thyroid have been postulated to arise from remnants of branchial derivatives; origination from solid cell nest remnants of the ultimobranchial bodies has been raised as a possibility. A definitive origin, however, has not been established. An association with chronic thyroiditis has been noted in 8 of the previously reported 16 cases occurring in a background of Hashimoto or chronic lymphocytic thyroiditis.

Abstract Background: Sarcoidosis is occasionally accompanied by hematologic malignancies, including lymphoma, called sarcoidosis-lymphoma syndrome. Although the mechanism underlying the induction of lymphomas is still unknown, understanding the immunological background of sarcoidosis could help explain the possible mechanisms of the induction of lymphomas. Case Presentation: A 52-year-old woman was diagnosed chronic thyroiditis with normal thyroid function. One year later, she underwent a screening chest radiograph and identified bilateral hilar adenopathy and mediastinum lymphadenopathy. Subsequent mediastinoscopy demonstrated sarcoidosis. Because of the lack of clinical symptoms, steroid treatment was not initiated and regular follow-up was performed. One and a half years after the diagnosis of chronic thyroiditis, she presented with rapid swelling of the thyroid gland. FDG-PET/CT showed intense uptake of FDG in the thyroid gland and multiple lymphadenopathy. Fine-needle aspiration (FNA) cytology of the thyroid gland was only suggestive of a lymphoproliferative disorder and did not provide a definitive diagnosis. Partial thyroidectomy was performed, and the pathology indicated diffuse large B-cell lymphoma (DLBCL) such as high-grade transformation of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma. The results of an examination of a paraffin block histopathology specimen by fluorescence in-situ hybridization (FISH) detected BCL6 rearrangement (3q27), which is the most common chromosomal abnormality in DLBCL. After the treatment with R-EPOCH (rituximab, etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisone) chemotherapy, the thyroid gland enlargement has improved markedly, while the lymph nodes remained swelling, that suggested lymph node involvements were due to sarcoidosis. Conclusions: Rapid swelling of the thyroid gland in the setting of chronic thyroiditis should raise suspicion for thyroid lymphoma. Furthermore, our present case might suggest that sarcoidosis accelerate the development and high-grade transformation of thyroid lymphoma. To our knowledge, this is the first reported case of sarcoidosis and primary thyroid lymphoma in the same patient.

The influence of aqueous extract from Lemna minor frond on morphological status of the thyroid gland in the experimental conditions of hypothyroidism in rats induced by administration of merkazolilum solution instead of drinking water for 30 days was studied. Thyreostatic merkazolilum resulted in changes of morphological structure of the thyroid gland, accompanied by manifestations of hyperplastic tissue proliferation and corresponds with hypofunctional state.The introduction of aqueous extract from Lemna minor frond resulted in positive influence on the restructuring of the thyroid gland in rats with hypothyroidism, increasing its functional activity. There was a decrease of proliferative processes of the epithelium and extrafollicular thyrocytes in follicles. The outer diameter of the follicles are not different from intact control, height follicular thyrocytes decreased compared with pathology by 41.08%. Iodomarin and L-thyroxine increased functional activity of the thyroid gland, but to a lesser degree than the aqueous extract from Lemna minor frond. L-thyroxine is not increased pharmacological effect of the studied extract. The results have practical significance for drugs development with thyroid-stimulating action.

The Mind

The thyroid gland has a profound influence on the mind, both in its emotional and its intellectual aspects. The emotional features of hyperthyroidism are too well recognized to need stressing. So, too, is the association between gross diminution of thyroid function and the mental incapacity of cretinism. It was suspected, therefore, that even in those types of mental deficiency in which diminution of thyroid function was not recognizable clinically, it might be possible to detect some evidence of abnormality in the thyroid gland by histological study. Further justification for presupposing the possibility of thyroid derangement may be found in the fact that in many conditions an association between the thyroid and thymus has been established, and that in mental deficiency the thymus undergoes premature atrophy.

Langerhans cell histiocytosis (LCH) is a rare sporadic proliferative disorder of Langerhans cells. LCH rarely involves the thyroid gland. We report herein a case of a disseminated chronic form of LCH with a diagnosis established by histological examination of the thyroid gland. It is about a 37-year-old female who underwent total thyroidectomy for a thyroid nodule of the right lobe. Histological study showed a granulomatous thyroiditis, and the immunohistochemistry study revealed a strong positivity of histiocytes for the CD1 antigen and for the S100 protein. The incidence of LCH involving the thyroid gland, either as an isolated lesion or as a part of multisystemic disease, is extremely rare.
