Diagnosis of Thyroid Nodules in Children and Adolescents with Subclinical Hypothyroidism and Their Outcomes after Early Thyroxine Treatment-A Longitudinal Study.

Pediatric thyroid nodules (TNs) present a higher malignancy rate compared to adults. We sought to diagnose the frequency and characteristics of TNs in children and adolescents with subclinical hypothyroidism (SH) and their outcomes after levothyroxine (LT4) therapy. A total of 256 children with TNs and SH were followed every semester from 2006 to 2018. All patients were treated with LT4. Clinical and radiologic findings, such as the size and texture of the nodules, were documented. Analysis included one-way ANOVA, Kruskal-Wallis, Chi-square, and Fisher's exact tests. After initial LT4 therapy, TNs disappeared in 85.5% and did not reappear throughout follow-up. In 14.5%, TNs remained the same or increased in size, but they decreased after subsequent LT4 administration with an increased dose. Thyroid disease family history (FHTD) was documented in 77.0%. In total, 64.5% developed a goiter, 46.0% exhibited thyroid heterogeneity on ultrasound, 23.4% had positive Anti-Tg, and 25.4% had positive anti-TPO autoantibodies. Our findings support the possible premise that early pharmacologic intervention with LT4 may be beneficial in children and adolescents with TNs and SH. The increased frequency of FHTD, goiter, thyroid heterogeneity, and Hashimoto in our patients emphasizes that thyroid ultrasounds may be warranted in children and adolescents with these characteristics in order to rule out the presence of TNs.

Long-term outcomes of radiofrequency ablation for intrathoracic goiter up to 5 years: evaluated by computed tomography/magnetic resonance imaging and ultrasound.

OBJECTIVES: This study evaluated the long-term efficacy and safety of radiofrequency ablation (RFA) for intrathoracic goiter (ITG) over a follow-up period exceeding six months. METHODS: From 2017 to 2022, 22 patients (6 males, 16 females) with 24 ITGs treated with RFA at a single medical center were evaluated. All patients underwent ultrasonography (US), computed tomography (CT), or magnetic resonance imaging (MRI) before RFA. Follow-up CT/MRI was performed six months after the initial RFA and then every 6-12 months. The primary outcomes measured were the degree of extension, goiter volume, volume reduction rate (VRR), tracheal deviation, and tracheal lumen. Additionally, we assessed the outcomes of single-session RFA (n = 16) vs. multiple sessions (n = 8) on goiters and explored the correlation between ITG volume measurements obtained using ultrasonography and CT/MRI. RESULTS: The median follow-up period was 12 months (interquartile range: 6-36.8 months). At the last follow-up, the nodule volume measured by CT/MRI had significantly decreased (76.2 vs. 24.6 mL; p < 0.05), with a VRR of 64.6%. Patients who underwent multiple RFA sessions showed a significantly higher VRR than the single-session patients (63.8 vs. 80.1%, p < 0.05). The intraclass correlation between goiter volumes measured using US and CT/MRI was moderate. CONCLUSION: This study affirms the long-term efficacy and safety of RFA for ITG, providing an alternative treatment for nonsurgical candidates. Multiple RFA sessions may be beneficial for achieving better volume reduction. Sole reliance on ultrasonography is inadequate; therefore, integrating CT/MRI is essential for accurate pre-RFA and follow-up assessments.

Intrathoracic goiters significantly impact both cosmetic appearance and induce numerous compressive symptoms.Radiofrequency ablation brought notable volume reduction and persistent, effective alleviation of compressive symptoms.Radiofrequency ablation presents a promising therapeutic modality with long-term benefits for patients with intrathoracic goiter.

Lithium carbonate-induced giant goiter and subclinical hyperthyroidism in a patient with schizophrenia: A case report and review of literature.

BACKGROUND: Lithium carbonate is used to manage various mood disorders, but it can cause thyroid abnormalities, including goiter, hypothyroidism, and hyperthyroidism. In rare cases, it can lead to giant goiter and subclinical hyperthyroidism, which may require surgical intervention in severe cases. CASE SUMMARY: This case represents a rare development of giant goiter and subclinical hyperthyroidism in a schizophrenia patient who was subjected to prolonged lithium carbonate treatment. The enlarged thyroid gland caused pressure on the airway and recurrent laryngeal nerve, which led to respiratory distress, hoarseness, and dysphagia. The immediate danger of suffocation required urgent surgical intervention. In this report, we describe the case of a 41-year-old Chinese woman. This sheds light on the etiology and challenges associated with managing a giant goiter. The patient underwent a subtotal thyroidectomy to relieve airway compression and facilitate airway expansion. Prior to the procedure, the patient was given iodine to prepare. Concurrently, changes were made to the psychiatric medication regimen. Following surgery, the patient's respiratory function and vocal cord functionality improved significantly, and her mental state remained stable. CONCLUSION: It is essential to monitor thyroid function, test thyroid antibody levels, and perform thyroid ultrasounds consistently in all patients undergoing long-term lithium carbonate treatment. This vigilance helps prevent severe and potentially life-threatening thyroid enlargement.

The common pathogenesis of nodular goiter in both sexes: An exploration into gene expression and signaling pathways.

The past few years have witnessed an increasing incidence of nodular goiter (NG), with a well-documented higher prevalence in females than males. This gender disparity has led research to focus primarily on female subjects, potentially overlooking common pathogenic mechanisms in both sexes. In this study, we investigated the shared pathogenesis of NG in males and females. Utilizing a rat model and RNA sequencing, we identified differentially expressed genes associated with the disease. We further validated these findings in normal human thyroid cells and human papillary thyroid cancer cells. A randomized experiment was conducted with equal numbers of male and female rats divided into control and NG model groups. The NG model was established using propylthiouracil and various assessments such as thyroid ultrasonography, thyroid index, thyroid function, and thyroid histology were performed. Transcriptome analysis revealed numerous upregulated and downregulated genes in both male and female model groups. Key genes like KDR, FLT1, PDGFB, and CAV1, and pathways including PI3K-Akt, MAPK, Ras, fluid shear stress and atherosclerosis, calcium signaling, and Rap1 signaling pathways were linked with the disease. Western blot and immunofluorescence analysis confirmed these findings, which were further supported by cell-based experiments. In conclusion, our findings suggest that abnormal expression of specific genes and pathways leading to irregular cell growth, blood vessel formation, and inflammation may be common factors in the pathogenesis of NG in both males and females.

Impact of Drain Placement on Postoperative Complications after Thyroidectomy for Substernal Goiter.

Introduction Despite the evidence against drain placement after thyroidectomy, there is a lack of consensus on drain use in patients with substernal goiter. Objective To assess the factors that increase the likelihood of drain placement and its impact on postoperative hematoma and other 30-day complications among adult patients undergoing thyroidectomy for substernal goiter. Methods A retrospective cohort study that used data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Adult patients (aged ≥ 18 years) who underwent elective thyroidectomy for substernal goiter from 2016 to 2020 were included. Cases with closed suction neck drains placed upon completion of surgery were included in the drain group, and the remaining cases formed the nondrain group. Results A total of 1,229 patients were included (46.5% with drain placement). The factors that increased the likelihood of drain placement included body mass index (BMI) ≥ 30 kg/m 2 , score between 3 and 5 on the American Society of Anesthesiologists (ASA) physical status classification, sternal split/transthoracic surgical approach, operative time ≥ 90 minutes, and surgery conducted by otolaryngologists. Patients with clean-contaminated or contaminated wound classifications were less likely to be submitted to drain placement. In addition, drain use had no impact on postoperative hematoma formation but was found to independently increase the risk of prolonged length of hospital stay. Conclusion Thyroidectomy without drain placement might be safe for substernal goiter. However, this decision should be individualized for each patient. Level Of Evidence: 3.

The Coexistence of Occult (Latent) Thyroid Cancer and Multinodular Goiter After Total Thyroidectomy: A Retrospective Study.

Introduction Multinodular goiter (MNG) is a common thyroid disorder characterized by the presence of multiple nodules within the thyroid gland. While most cases of MNG are benign, there is a risk of malignancy, particularly in nodules with certain features. The coexistence of occult (latent) thyroid cancer within MNG presents diagnostic and management challenges, underscoring the need for comprehensive investigation and treatment strategies. Objective The objective of this retrospective study is to investigate the prevalence of occult thyroid carcinoma in non-toxic MNG following total thyroidectomy. Materials and methods The study population consisted of 412 patients who underwent total thyroidectomy between 2004 and 2022 at the Second Surgical Department of the 424 General Military Hospital of Education in Thessaloniki. Data collection included patients' demographic characteristics, surgical indications for thyroidectomy, and histopathological examination findings. Initial data were available for all 412 patients, while sufficient information was present for 319 individuals, with a subset of 271 undergoing total thyroidectomy due to non-toxic MNG. Out of the aforementioned group, 253 cases were histologically confirmed as MNG. Subsequently, a statistical analysis was conducted concerning age, gender, the association of MNG with malignancy, and other thyroid disorders. Results Out of the total 412 thyroidectomies performed, 271 patients remained for statistical analysis and study. Among them, 253 patients had histologically confirmed MNG. Among the histological findings, 38 cases (14.02%) were identified with occult carcinoma within MNG. The predominant histological type was papillary thyroid carcinoma (PTC), comprising 93.3% of cases. Additionally, 18 patients (6.64%) were diagnosed with MNG, Hashimoto's thyroiditis (HT), and malignancy concurrently. Conclusions The coexistence of occult thyroid carcinoma within MNG underscores the importance of vigilant evaluation and management strategies in patients undergoing total thyroidectomy. These findings emphasize the need for comprehensive preoperative assessment and postoperative surveillance to detect and address occult thyroid cancer, thereby optimizing patient care and outcomes.

Ultrasound predictive parameters of difficult airway in thyroid surgery: a pilot study.

Difficult airway is a major life-threatening complication during induction of general anesthesia. In thyroid surgery, intubation could be complicated by airway distortion because of the enlarged thyroid gland. Recently, ultrasonography has been proposed as a potential modality for airway assessment and management. The aim of the study is to evaluate ultrasound-based measurement of airway parameters in 13 selected patients with compressive goiter and tracheal deviation scheduled for thyroidectomy before induction of general anesthesia. Specifically, we detected the distance between the skin and retro-isthmic trachea (DSRIT) and the distance between the sub isthmic trachea and the carotid artery (DCSIT) at the side of the dominant lobe. We compared ultrasound measures before intubation with Cormack-Lehane laryngoscopes grades recorded during tracheal intubation.

To elucidate the mechanism of "Scrophulariae Radix-Fritillaria" in goiter by integrated metabolomics and serum pharmaco-chemistry.

The pharmacodynamic substances in "Scrophulariae Radix-Fritillaria" and the molecular mechanisms underlying its therapeutic effects against goiter were analyzed through metabolomics and serum pharmaco-chemistry. A rat model of goiter was established using propylthiouracil (PTU), and the animals were treated using "Scrophulariae Radix-Fritillaria." The efficacy of the drug pair was evaluated in terms of thyroid gland histopathology and blood biochemical indices. Serum and urine samples of the rats were analyzed by UPLC-Q-TOF/MS. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were performed to screen potential biomarkers in urine and the corresponding metabolic pathways. The blood components of "Scrophulariae Radix-Fritillaria" were also identified, and their correlation with urine biomarkers was analyzed in order to screen for potential bioactive compounds. "Scrophulariae Radix-Fritillaria" mitigated injury to thyroid tissues and normalized the levels of the thyroid hormones FT3, FT4, and TSH. We also identified 22 urine biomarkers related to goiter, of which 19 were regulated by "Scrophulariae Radix-Fritillaria." Moreover, urine biomarkers are involved in tryptophan metabolism, steroid hormone biosynthesis, and beta-alanine metabolism, and these pathways may be targeted by the drug pair. In addition, 47 compounds of "Scrophulariae Radix-Fritillaria" were detected by serum pharmacochemistry, of which nine components, namely, syringic acid, paeonol, cedrol, and cis-ferulic acid, fetisinine, aucubigenin, linolenic acid, ussuriedine, and 5-(methylsulfanyl)pentanenitrile, were identified as potential effective substances against goiter. To summarize, we characterized the chemical components and mechanisms of "Scrophulariae Radix-Fritillaria" involved in the treatment of goiter, and our findings provide an experimental basis for its clinical application.

Unusual congenital goiter due to maternal Hashimoto thyroiditis: a case report.

Congenital hypothyroidism (CH) is the most common cause of endocrinopathy in the newborn Its incidence lies between 1 in 3,000 and 1 in 2,000, However, congenital goiter is a rare form of presentation. Hypothyroidism secondary to autoimmune etiology is extremely rare, with an incidence of 1:84.700-1:31.000 newborns. Anti-thyroid peroxidase antibodies (TPOAb) are able to cross the placenta but rarely induce hypothyroidism in the newborn, much less goiter. A case of congenital goiter in a male newborn secondary to maternal high TPOAb levels is reported. The mother was diagnosed of Hashimoto thyroiditis prior to the pregnancy. At birth, a grade 3 goiter was detected in the newborn. Laboratory testings revealed hypothyroidism with free thyroxine of 7.6 pmol/L, thyroid-stimulating hormone of 108 mUI/L and high TPOAb levels. Treatment with Levothyroxine was started the second day of life with progressive thyroid function normalization. Neurological development has been normal until the date.

[Thyroid surgery in a context of scarce resources at Saint Martin de Porres Dominican Hospital (Yaounde, Cameroon)]. / Chirurgie thyroïdienne dans le contexte de populations avec de faibles ressources à l'hôpital dominicain Saint Martin de Porres (Yaoundé, Cameroun).

Introduction: Surgical campaigns for thyroid surgery in low-income environments are very efficient, but there is little literature reporting results. These campaigns are complex due to multiple particularities: highly evolved cases, the need for professionals to travel or an obvious socio-cultural barrier influence towards the surgical act. We describe a surgical campaign in Cameroon to treat patients with goiter and issue some medical and sociocultural recommendations in view of our experience for its implementation with guarantees. Material and methods: An experienced group carried out an 11-day campaign at the Saint Martin de Porres Dominican Hospital, Yaounde, Cameroon. Demographic data, TSH values, surgery and complications after a 12-month follow-up were analyzed. Results: Thirty-eight patients with goiter were selected for the campaign and 32 patients (mean age, 40-years-old; 30 females) were operated. Bilateral goiter, as assessed with echography, was diagnosed in 13 patients (41%). Ten patients (31%) had a WHO grade II goiter (visible with the neck in a normal position). The surgical procedures were 18 unilateral thyroidectomy with isthmectomie, 13 total thyroidectomy, and 1 totalizing thyroidectomy, due to previous unilateral thyroidectomy (cancer recurrence). A pathological study in 13 patients (40%, extra cost 60 €) showed benign multinodular goiter/thyroid nodule (12 patients) and an extensive papillary carcinoma (one patient). Six months postoperatively, 3 patients had a slight dysphonia and one patient had persistent hypocalcemia. Follow-up was completed in all patients, either face to face (75%, 24 patients) or by phone (25%, 8 patients who failed to have a TSH test because of its cost, 23 €). Conclusions: Surgical campaigns to treat thyroid pathology can be carried out with guarantees if a series of important steps are followed: active participation of the patient's environment, thyroid ultrasound by the surgical team to decide which technique, intense awareness about monitoring and hormone replacement therapy, and the participation of local personnel for long-term follow-up.

Highlighting the contribution of the Greek physician Theodoros Aretaios to the history of thyroidectomy.

Theodoros Aretaios (1829-1893), having pursued advanced studies at home and abroad and possessing a wide range of competences and interests, was among the first Greek physicians to produce educational treatises for both students and doctors of medicine. Among these is his medical treatise Surgery which deals with thyroid operations and goiter symptoms as well as post-operative lesions which included a record of his extensive experience, learned recommendations, deep insights, and advanced techniques. In this medical archive, which is preserved in the National Library of Greece, there is, for example, the physician's vivid description of a thyroidectomy that he performed which illustrates his expertise as a surgeon as well as the surgical knowledge of his times. Aretaios was not the first to perform this operation in Greece: he was, however, the first to document it, which he did for the benefit of his fellow Greeks and of surgeons worldwide.

Incomplete partition type II in its various manifestations: isolated, in association with EVA, syndromic, and beyond; a multicentre international study.

PURPOSE: Incomplete partition type II (IP-II) is characterized by specific histological features and radiological appearance. It may occur in isolation or in association with an enlarged vestibular aqueduct (EVA). Among those with IP-II and EVA, a subset has a diagnosis of Pendred syndrome. This study aimed to explore the prevalence of isolated IP-II, IP-II with EVA, and cases with a genetic or syndromic basis in our cohort. METHODS: From a large, multicentre database of dysplastic cochleae (446 patients, 892 temporal bones), those with imaging features of IP-II were examined in detail, including whether there was a genetic or syndromic association. RESULTS: A total of 78 patients with IP-II were identified. Among these, 55 patients had bilateral IP-II and EVA (only 12 with typical Mondini triad), 8 with bilateral IP-II and normal VA, 2 with bilateral IP-II and unilateral EVA, and 13 with unilateral IP-II (9 with unilateral EVA). Among the group with bilateral IP-II and bilateral EVA in whom genetic analysis was available, 14 out of 29 (48%) had SLC26A4 mutations and a diagnosis of Pendred syndrome, 1 had a FOXI1 mutation, and a few other genetic abnormalities; none had KCNJ10 pathogenic variants. CONCLUSION: Bilateral IP-II-bilateral EVA may be seen in the context of Pendred syndrome (SLC26A4 or FOXI1 mutations) but, in the majority of our cohort, no genetic abnormalities were found, suggesting the possibility of unknown genetic associations. IP-II in isolation (without EVA) is favored to be genetic when bilateral, although the cause is often unknown.

Exploring the potential of genetic analysis in historical blood spots for patients with iodine-deficient goiter and thyroid carcinomas in Switzerland and Germany (1929-1989).

Iodine deficiency-induced goiter continues to be a global public health concern, with varying manifestations based on geography, patient's age, and sex. To gain insights into clinical occurrences, a retrospective study analyzed medical records from patients with iodine deficiency-induced goiter or thyroid cancer who underwent surgery at the Community Hospital in Riehen, Switzerland, between 1929 and 1989. Despite today's adequate iodine supplementation, a significant risk for iodine-independent goiter remains in Switzerland, suggesting that genetic factors, among others, might be involved. Thus, a pilot study exploring the feasibility of genetic analysis of blood spots from these medical records was conducted to investigate and enhance the understanding of goiter development, potentially identify genetic variations, and explore the influence of dietary habits and other environmental stimuli on the disease.Blood prints from goiter patients' enlarged organs were collected per decade from medical records. These prints had been made by pressing, drawing, or tracing (i.e., pressed and drawn) the removed organs onto paper sheets. DNA analysis revealed that its yields varied more between the prints than between years. A considerable proportion of the samples exhibited substantial DNA degradation unrelated to sample collection time and DNA mixtures of different contributors. Thus, each goiter imprint must be individually evaluated and cannot be used to predict the success rate of genetic analysis in general. Collecting a large sample or the entire blood ablation for genetic analysis is recommended to mitigate potential insufficient DNA quantities. Researchers should also consider degradation and external biological compounds' impact on the genetic analysis of interest, with the dominant contributor anticipated to originate from the patient's blood.

Long-Term Effects of 0.1 mg Recombinant-Human-Thyrotropin-Stimulated Fixed-Dose Radioiodine Therapy in Patients with Recurrent Multinodular Goiter after Surgery.

(1) Background: After thyroid malignancy is ruled out, treatment options for multinodular goiter patients include surgery, levothyroxine suppressive therapy, and 131-I therapy. Surgery effectively reduces goiter size but carries risks of surgical and anesthetic complications. 131-I therapy is the only nonsurgical alternative, but its effectiveness diminishes with goiter size and depends on iodine sufficiency. This study aimed to assess the efficacy and safety of 0.1 mg rhTSH as an adjuvant to a fixed dose of 131-I therapy in patients with a recurrence of large multinodular goiter, several years after the initial thyroidectomy. (2) Methods: 14 patients (13 females and 1 male), aged 59.14 ± 15.44 (range, 35-78 years) received 11mciu of 131-I, 24 h after the administration of 0.1 mg rhTSH. The primary endpoint was the change in thyroid volume (by ultrasound measurements) as well as in the diameter of the predominant nodule during a follow-up period of 10 years. Secondary endpoints were the alterations in thyroid function and potential adverse effects. (3) Results: A significant decrease in the volume of initial thyroid remnants (32.16 ± 16.66 mL) was observed from the first reevaluation (at 4 months, 23.12 ± 11.59 mL) as well as at the end of the follow-up period (10 years, 12.62 ± 8.76 mL), p < 0.01. A significant reduction in the dominant nodule was also observed (from 31.71 ± 10.46 mm in the beginning to 26.67 ± 11.05 mm). (4) Conclusions: Further investigation is needed since this approach could be attractive in terms of minimizing the potential risks of reoperation in these patients.

Evaluation of the ultrasound findings of thyroid gland enlargement in Cape Coast Teaching Hospital, Ghana: A retrospective cross-sectional study.

Background and Aim: Goiter is a major source of morbidity in the world, especially in the developing world, where dietary iodine deficiency, a known cause of this condition, is endemic. The diagnosis is mostly by ultrasonography (USG) scan, which can give anatomical, pathological, and functional information for the management of goiter. This study aimed to determine the commonest ultrasound findings of goiter in Ghana. Method: The records of all 213 patients with goiter diagnosed by USG scan over a 5-year period were retrieved. Data collected were sociodemographics, ultrasound features, thyroid nodules diameter, and Thyroid Imaging Reporting and Data System (TI-RADS) scores, which were analyzed using GNU PSPP, version 1.2.0-3. χ 2 and two-tailed independent samples t-test were also employed, with p ≤ 0.05. Results: A total of 213 patients with goiter diagnosed by USG scan were obtained over the study period. The mean age of the participants was 50.01 ± 17.27 years, with an age range of 16-92 years and females constituting the majority (82.16%). The commonest ultrasound features were well-defined solid nodules. The lesion sites for most patients were the whole thyroid (28.17%), both lobes (24.41%), and the right lobe (20.19%). The mean difference in sizes of cysts and solid nodules among genders was 0.26 (CI: -0.14 to 0.67, p = 0.20) and 0.12 (CI: -0.43 to 0.66, p = 0.67), respectively. The TI-RADS score featured TI-RADS 4 (36.62%), TI-RADS 1 (28.17%), TI-RADS 3 (25.82%), TI-RADS 5 (5.16%), and TI-RADS 2 (4.23%). Solid nodules (49.32%, p = 0.001) and cysts (35.71%, p = 0.003) were more common within 41-60 years and less frequent in those <21 years. A p ≤ 0.05 was considered significant in this study. Conclusion: The predominant ultrasound features were well-defined solid nodules, simple cysts, and solid nodules with cystic changes, mostly located in the entire thyroid gland and least located in the isthmus only. Cysts and solid nodules were mostly seen in the 41-60 years age group.

Two Cases of Painful Thyroiditis With Subsequent Hypothyroidism Following Cord Blood Transplant.

We report two rare cases of painful thyroiditis approximately 100 days after unrelated cord blood transplantation (CBT), which progressed to hypothyroidism. Patient one, a 45-year-old woman, developed goiter, tenderness, and thyrotoxicity on day 100 after CBT for relapsed acute lymphocytic leukemia. Scintigraphy suggested destructive thyroiditis; symptoms improved with one-month beta-blocker and prednisolone treatment. Two months later, hypothyroidism developed which required supplementation-based treatment. Patient two, a 49-year-old man, developed goiter, tenderness, and thyrotoxicosis on day 96 after CBT for acute myelogenous leukemia. Hypothyroidism developed after nonsteroidal anti-inflammatory drug treatment. Thyroiditis and hypothyroidism should be considered in patients who develop neck pain after CBT.

Diffuse Thyroid Lipomatosis and Amyloid Goiter With Incidental Papillary Thyroid Carcinoma: A Rare Case Report.

Lipoid lesions of the thyroid gland are very rare. Fat-containing thyroid lesions include a variety of clinical-pathological disorders, such as adenolipomas, thyrolipomatosis, and lipomatous tissue, in the event of amyloidosis. Herein, we report a case of diffuse thyrolipomatosis with amyloidosis and incidentally detected papillary carcinoma of the thyroid in a 51-year-old female patient who clinically presented with a multinodular goiter. Amyloidosis in papillary carcinoma of the thyroid is very rare and can be primary or secondary amyloidosis. Thyrolipomatosis, amyloid goiter, and papillary carcinoma of the thyroid is a rare combination, and to our knowledge, this is the third reported case in the literature. The association of amyloidosis and the rare occurrence of a differentiated carcinoma have to be considered, as in the case of thyroid lipomatosis.
