Guest guest Posted January 2, 2006 Report Posted January 2, 2006 Real close to 2 months since my TT. I'm rereading all my test results I obtained. I still need to get a copy of the surgical report and 3 blood tests. In my path report it says " background multinodular hyperplasia with hurthle cell change. " Does anyone know what that means, the hurthle part ? For the other lobe it just says " background multinodular hyperplasia. " I figure that is better news. My next endo appt is early Feb and I intend to ask all my test result questions then. The left lobe says the nodule 3.6x3.2x3.0 cm. It was a big mother! 5 nodules make up that big mother. At one point the report says " there is no vascular or capsular invasion grossly identified. " But then later under the microscopic findings, it says " tumor is present in small vessels surrounding the nodule. " When I was endo doc shopping, one said vascular invasion meant the cancer had a blood supply. The other one said cancer had gone into the blood vessels in the thyroid. So is the path report saying both things here ? What does " cystic degeneration " mean? Right thyroid largest nodule 3.5x2.9 cm. And just now rereading it, the last words are that 2 flattened parathyroid glands are present adjacent to the nodule. That means I only have 2 left. First time seeing that, it hasn't been pointed out to me. Surgeon told me, if I heard right on very little sleep and on pain meds, that he'd been able to keep the parathyroids in. Think I'll have endo or his PA go over reports with me line by line, explaining. I knew I needed to reread these results and reports, but haven't felt up to it. I did it a couple days ago and cried as I read. These things that were done to me and have gone on in me. And this is enough for tonight. Pace myself out. I'll dig into more later. Thanks in advance to those who take time to reply. jane<---on the laptop with cat making a very good armrest !

" Does anyone know what that > means, the hurthle part ? For the other lobe it just says " > background > multinodular hyperplasia. " I figure that is better news. Multi means multiple.. Nodular refers to nodules, growths. Hyper means excessive..more than.. Plasia refers to cell growth.. Hurthle cell change refers to what the cells look like under a microscope..this refers to changes in the cellular structure usually associated with cell damage from Hashimoto's..this is the most common type of thyroid cancer and why they reccomend a suppressed TSH below 1 with someone with Hashimoto's disease. (Hurthle cells may or may not be cancerous but represent a non uniform cellular structure change which is a signal for cancer depending on the shape of the cells.) Basically the report means your thyroid was enlarged and contained more than one nodule and showed changes in the cellular structure consistant with abnormal cell formation in one side of the thyroid. The most common and easily treated type of cancer involves Hurthle cells.. Kats3boys Quote

Guest guest Posted January 4, 2006 Report Posted January 4, 2006 Thanks Kats. I'm waiting for endo's PA, who handles patient questions, to call, for us to connect. Seems in my reading, I heard Hurthle is one of the worse thyca's. I also read it can mean a precancerous condition. Since I had papca, well, it makes sense. Just want to make sure there's not Hurthle cancer too. I had 3 docs tell me my thyroid was close to dying, so it makes sense what cystic degeneration means. About the flattened parathyroids the pathology report says. Since the report came from looking at my removed thyroid, wouldn't it be commenting on what it found in the tissues submitted ? And so, wouldn't saying there are 2 flattened parathyroids mean the parathyroids, flattened, were on the thyroid lobe submitted ? Would the lobe show that the paras had been flattened against them but now paras are still in my neck ? Just found out today it's normal for me to still be so fatigued. That, and knowing what the path report means, is a great relief. Thanks. I need to ask for a copy of the surgical report and a couple blood tests. Writing that down now, cuz I will forget with this still hypo brain. I do lab work on the adrenal growth tomorrow, for me, Wednesday. jane tt 11/7/05papca encap; vasc inva 12/5/05rai 139 11/25/05wbs 12/2/05 normal post ttlevothyroxine 200 12/9/05 From: kats3boys blood tests.

From Merck.. PAPILLARY CARCINOMA Papillary carcinoma is the most common thyroid cancer (60 to 70% of all thyroid cancers). Females are affected two to three times more often than males. It is more frequent in the young, but is more malignant in the elderly. It is more common in patients with a history of radiation exposure and spreads via the lymphatic system. Lateral aberrant thyroid rests may be found that are actually occult metastases with a benign histologic appearance. These well- differentiated cancers may be TSH-dependent and may develop in goiters secondary to Hashimoto's thyroiditis. Many papillary carcinomas contain follicular elements, but this does not alter the basic biology of the tumor. Treatment Treatment for small (< 1.5 cm) encapsulated tumors localized to one lobe is usually lobectomy and isthmectomy, although some experts recommend more extensive thyroid surgical treatment. Thyroid hormone in TSH suppressive doses is given to minimize chances of regrowth or to regress any microscopic remnants of papillary carcinoma; surgical treatment is almost always curative. Large (> 1.5 cm) or diffusely spreading tumors often require total or near-total thyroidectomy with postoperative radioiodine scans and subsequent ablation of residual thyroid tissue with appropriately large doses of 131I administered when the patient is hypothyroid. Alternatively, recombinant TSH can be administered for 2 days prior to 131I for the diagnostic scan to detect residual thyroid tissue or cancer, thus avoiding the need to let the patient become hypothyroid prior to the diagnostic scan. Repeat treatment may be required every 6 to 12 mo to achieve ablation of the remaining thyroid tissue. TSH suppressive doses of L-thyroxine are given after treatment, and measurement of serum thyroglobulin is useful in detecting recurrent or persistent disease. From the Thyroid manager Pathology ( Hashimoto's) The goiter is generally symmetrical, often with a conspicuous pyramidal lobe. Grossly, the tissue involved by Hashimoto's thyroiditis is pinkish-tan to frankly yellowish and tends to have a rubbery firmness. The capsular surface is gently lobulated and non- adherent to peri-thyroid structures. Microscopically, there is a diffuse process consisting of a combination of epithelial cell destruction, lymphoid cellular infiltration, and fibrosis. The thyroid cells tend to be slightly larger and assume an acidophilic staining character; they are then called Hurthle or Askanazy cells and are packed with mitochondria. The follicular spaces shrink, and colloid is absent or sparse. Fibrosis may be completely absent or present in degrees ranging from slight to moderate; it may be severe, as observed in subacute or Riedel's thyroiditis. Foreign body giant cells and granulomas are not features of Hashimoto's thyroiditis, in contrast to subacute thyroiditis. In children, oxyphilia and fibrosis are less prominent, and hyperplasia of epithelial cells may be marked. Deposits of dense material representing IgG are found along the basement membrane on electron microscopy . FNA can be a useful diagnostic procedure but is infrequently required, except in patients that seem to have- or have- a discreet nodule in the gland. FNA typically reveals lymphocytes, macrophages, scant colloid, and a few epithelial cells which may show Hurthle cell change. In this context Hurthle cells do not represent a discrete adenoma. However if only abundant Hurthle cells dominate the specimen, and there are few or no lymphocytes or macrophages, the biopsy must be interpreted as a possible Hurthle cell tumor. Biopsy results are less frequently diagnostic in children(95). Hope this helps with what I was trying to say. Kats3boys. Quote
