Thyroid gland lies over representative box seat in neck . Thyroid nodule is solitary ( single ) or multiple stumblebum experience over midway or side of neck over the thyroid secretory organ . legal age of thyroid nodules do not cause serious condition and may not make any symptoms . Most thyroid nodules are incidental and found while rubbing the neck by somebody or during radiological study , which is performed to govern out other diseases locate around neck . Scientific written report involving 122 affected role intimate lonely or single modest thyroid nodule in younger patient more likely have home history of cancer and should be measure to rule out cancer . While large thyroid gland nodule in patients older than 45 twelvemonth is more in all likelihood benign1 .
Thyroid secretory organ secretes thyroid gland endocrine . Thyroid tubercle is count as insensate , fond or red-hot . cold-blooded thyroid tubercle does not raise any hormone . Similarly thyroid tubercle is look at affectionate or blistering depending on amount of thyroid hormone secreted by thyroid tissue mold adenoma . quick or hot thyroid gland nodule is also known as follicular adenoma . Patient may suffer with lone or single thyroid gland nodule or multiple active thyroid gland tubercle or follicular adenoma . Hard and painful solitary or single adenoma should be appraise for thyroid cancer or neoplasm .
The thyroid gland tubercle is known as toxic adenoma when thyroid gland tissue within nodule secretes excessive thyroid hormones . Increased secernment of thyroid gland hormone often do symptom identified as thyroid gland toxicity . Rarely non - cystic tubercle may be filled with blood clots , fibrous tissue paper or calcium deposits . Cystic tubercle is filled with serous fluid and often grows rapidly
Causes of Solitary or Single Thyroid Nodule
Solitary or Single Thyroid Nodule Caused Due to Hypertrophy of Thyroid Tissue- In most case normal thyroid tissue within thyroid nodule becomes participating and increases in size resulting in nodule constitution . The experimental condition is benignant when gland does not secrete any additional thyroid gland endocrine . Such condition of thyroid nodule is considered as cold nodule . The hormone secreting thyroid nodule is identified as tender or hot adenoma . Hot thyroid gland nodule secrete higher volume of thyroid gland endocrine than quick thyroid nodule . The condition is often asymptomatic when single ardent or hot nodule secretes marginally superfluous thyroid gland internal secretion . The multiple thyroid hormone secrete nodules may stimulate symptom ofhyperthyroidism .
Iodine Deficiency - Iodine inadequacy often causes nodular thyroid disease resulting in solitary or undivided thyroid nodule . Iodine deficiency is rare in developed country . Iodine deficiency resulting in thyroid tubercle is extremely rare in Australia , Canada , USA or Europe . The relative subject in Belgium , which was published in scientific daybook suggests iodine want in childhood leads to thyroid tubercle organisation and involve for aggressive treatment2 .
Inflammation of Thyroid Gland - Thyroid gland inflammation is known as thyroiditis . Inflammation of individual or multiple thyroid gland nodules causes minify secretion of thyroid hormone within the nodule . tenacious - term continuing excitement of thyroid gland causesHashimoto ’s disease . Hashimoto ’s disease is associate with fibrosis of thyroid gland nodule and surround thyroid tissue . Disease results in loss of hormone produce thyroid gland secretory organ cells . Reduction in pregnant quantity of thyroid gland hormone results in circumstance known ashypothyroidismormyxedema .
Cystic Cause of Solitary or Single Thyroid Nodule - Degenerative changes in hypertrophied thyroid gland adenoma or normal thyroid secretory organ causes cystic swelling . The cyst is fill with mobile and thyroid gland cells . The surrounding thyroid gland tissue may be covered by calcify particles . Cystic swelling may not release any thyroid hormone . The cancerous ontogenesis within cystic tubercle of thyroid gland has been bring out and super rare3 .
Neoplasm - Cancer of thyroid gland is uncommon . But if thyroid gland nodule is single and painful then neoplasm or cancer of nodule should be ruled out by perform biopsy and microscopic work . Metastasis to single thyroid gland nodule is uncommon . Though a case report published in scientific journal suggest kidney cancer was find out metastasize as a single solitary thyroid nodule4 .
