The follicular variant, on its turn, rarely presents with such a mutation.
Clinical variants such as giant molluscum and follicular variants can make diagnosis more difficult.
BRAF mutation frequency was 43.8%, being higher in tall cell variant 80% andin the classic variant 68.3% and lowest in the follicular variant 18.8.
Our patient presented a well-differentiated papillary microcarcinoma follicular variant secondary to or concomitant with chronic lymphocytic leukemia with regional LN metastases.
The variants T zone lymphoma and the lymphoepithelioid lymphoma Lennert';s lymphoma were maintained, with the follicular variant being incorporated.
Studies have shown that,despite some histological differences observed between the Classic and Follicular variants of thyroid PC, both neoplasms have favorable prognosis and similar cancer-specific survival at 10 and 15 years.
We observed that the Microcarcinoma variant was the most prevalent, with 42.1% of cases,followed by the Classical and Follicular variants, respectively Table 3.
The pathological diagnosis of the excised material reported:“follicular variant of papillary microcarcinoma of the thyroid in the right lobe, confined to the thyroid gland, measuring 1.2mm, without involvement of surgical margins, extrathyroid tissue, or vascular invasion; multinodular goiter with foci of lymphocytic thyroiditis”.
The most prevalent variant or differentiation pattern in our study, grouped microcarcinomas, was the Classic,followed by the Follicular variant or pattern.
It is known that the follicular variant diagnosis of CP in the preoperative period is a challenge, both from the cytology point-of-view as well as the clinical-echographical point of view, which may have delayed the diagnosis of this tumor variant and justify the larger diameter this histological subtype in relation to the classical form of PCin our sample.
The bilateral maxillectomy recurrence happened to one patientcoming from another clinic, with a prior history five years before of the maxilla follicular variant of ameloblastoma.
Finally, the presence or absence of the BRAF mutation in cases with assessable result was correlated with the different histologic variants present classical variant, follicular variant and tall cells variant and, with different prognostic factors in papillary carcinoma age, lymph node metastasis, distant metastases, presence of multifocal tumor, presence of extravasation of thyroid capsule with invasion of adjacent structures, presence of blood or lymphatic vascular invasion and the occurrence of local or regional recurrence.
Ozdemir et al. showed greater tumor diameter, although lower prevalence of capsular invasion andextraglandular extravasation among Follicular variant cases when compared to the Classic one.
Among the cases classified as follicular pattern 38, 29 were benign follicular adenomas and nine malignant, two cases of follicular carcinoma andseven of papilliferous carcinoma- follicular variant.
Postoperative pathology tests revealed that 2 6% patients had well-differentiated malignant disease,both cases of follicular variant of papillary carcinoma with sizes ranging between 1 and 2 centimeters.
In the remaining 38 cases, the FS kept the appearance of a follicular pattern, suggesting that one should wait for the paraffin results; of these, 29 came as follicular adenomas and nine came as carcinoma,two follicular carcinoma and seven papilliferous of the follicular variant.
Lang et al. observed fewer metastatic lymph nodes andlower extraglandular overflow rate among the Follicular variant cases when compared to the usual forms of PC.
The term follicular lesion was used only for benign tumors with follicular cell groups arranged in thyroid follicles,excluding follicular carcinoma and the follicular variant of thyroid PC.
To evaluate the usefulness of c-met, hgf, stat3, and its phosphorylated form(pstat3) protein expression in the diagnosis and prognosis of patients with thyroid nodules, we analyzed 356 thyroid tissues, including 153 papillary carcinomas(ptc), 95 classical type,47 follicular variants of papillary carcinoma, and 11 tall cells carcinomas; 34 follicular carcinomas(fc), 34 follicular adenomas(fa), 124 goiters and 11 normal tissues. all patients were treated and monitored accor.
However, this difference was not maintained when we compared the diameter between the Classical and Oncocytic variants p 0.2842, as well as when we compared the Follicular and Oncocytic variants p 0.2129,only the Classical and Follicular variants, as per the Mann-Whitney U test p 0.002.
Lupi et al. studied 500 patients with papillary thyroid carcinomas 230 microcarcinomas, 82 classic variants, 114 follicular variants, 40 tall cell variants and 34 other variants. .
However, about 15 to 30% of the cytologic results of fnabs are classified as proliferative lesions, bethesda iii or iv category. the proliferative lesions are a great challenge in diagnostic practice since so far the distinction between adenomatous goiter,follicular adenoma, follicular carcinoma and papillary carcinoma follicular variant is only possible by histological study.
Moreover, under the same staging classification,there is no evidence that the thyroid PC Oncocytic variant differs from the usual forms and the PC Follicular variant in biological behavior and malignancy potential.
In patients initially subjected to partial thyroidectomy, surgical complementation may be avoided in cases of papillary carcinoma presenting with the characteristics described above as well as in cases of minimally invasive follicular carcinoma and the capsulated follicular variant of papillary carcinoma without vascular invasion measuring up to 2 cm.
