Background: The aim of this retrospective study was to investigate clinical and pathological characteristics of the tall cell variant of papillary thyroid carcinoma compared to conventional variants. Methods: The clinical records of patients who underwent surgical treatment between 2009 and 2015 were analyzed. The patients were divided into two groups: those with a histopathological diagnosis of tall cell papillary carcinoma were included in Group A, and those with a diagnosis of conventional variants in Group B. Results: A total of 35 patients were included in Group A and 316 in Group B. All patients underwent total thyroidectomy. Central compartment and lateral cervical lymph node dissection were performed more frequently in Group A (42.8% vs. 18%, p = 0.001, and 17.1% vs. 6.9%, p = 0.04). Angiolymphatic invasion, parenchymal invasion, extrathyroidal extension, and lymph node metastases were more frequent in Group A, and the data reached statistical significance. Local recurrence was more frequent in Group A (17.1% vs. 6.3%, p = 0.02), with two patients (5.7%) in Group A showing visceral metastases, whereas no patient in Group B developed metastatic cancer (p = 0.009). Conclusions: Tall cell papillary carcinoma is the most frequent aggressive variant of papillary thyroid cancer. Tall cell histology represents an independent poor prognostic factor compared to conventional variants.

BACKGROUND Papillary thyroid carcinoma is the most common malignancy of the thyroid gland. Fine Needle Aspiration Cytology (FNAC) is a rapid, safe and economic procedure, and has a sensitivity approaching of 93.5 % and specificity close to 90 % for diagnosing papillary thyroid carcinomas. This study aims at correlating the cytological and histological diagnosis to arrive at the rate of concordance and discordance, identify variants of papillary thyroid carcinoma (PTC) on cytology and discuss the cytological mimics of PTC. METHODS Data from cases was collected over a period of three years (2015 - 2018). A descriptive study was done. Cases from Osmania General Hospital representing histologically proven cases of papillary carcinoma thyroid along with their corresponding cytological findings were analysed. Cytosmears were obtained from fine needle aspiration of thyroid lesions using a 26-gauge needle, stained with haematoxylin and eosin (H&E). Thyroidectomy specimens were fixed in 10 % buffered formalin, grossed and paraffin embedded. After processing, sections obtained by microtomy were stained with H & E for histopathologic evaluation. RESULTS The institute received a total of 258 thyroid specimens for histopathology and 686 cases for thyroid FNAC over a period of three years. This study includes 70 cases which had both cytology and histopathology correlation at our institution. 65 cases were diagnosed as PTC on histopathology and correct diagnosis was made on cytology with 73.8 % concordance (48 / 65 cases) and discordance was seen in 26.1 % (17 / 65 cases). 5 cases were misdiagnosed on cytology as PTC, and on histopathological examination were diagnosed as non-PTC. CONCLUSIONS Fine needle aspiration shows variable accuracy for PTC, ranging from 65 % to 90 %. The architectural arrangement of cells in papillary fragments and presence of nuclear features in majority of cells is diagnostic of the conventional variant of PTC. The other variants however, pose a diagnostic dilemma on account of their architectural variation, altered cytomorphology and the scant presence of nuclear features. An increase in the awareness of cytomorphology of variants and also of the mimics of PTC helps improve the diagnostic accuracy on FNAC.

Clinical Pictures

Background: Lichen amyloidosis, a type of primary localized cutaneous amyloidosis, is characterized by pruritic brown or grayish pigmented papules. Objective: We report a case of lichen amyloidosis in which the skin lesion consisted of asymptomatic salmon-pink-colored papules on the back of the neck to the upper back. This was different from typical clinical pictures of lichen amyloidosis. Our patient proved to have thyroid papillary carcinoma. Conclusion: Our case may suggest that lichen amyloidosis could be a cutaneous manifestation of thyroid cancers.

The case of a 50-year-old woman with cerebral meningioma and concomitant parathyroid adenoma and papillary thyroid carcinoma is presented. She complained of neurological symptoms characterized by right hemiparesis and dysarthria. Cerebral CT and MRI scans revealed a left voluminous frontal parasagittal lesion with the characteristics of a meningioma. Routine laboratory analysis revealed altered values of calcium-phosphorus metabolism. Intravenous infusion of saline solution at 0.9% of NaCI resulted in a reduction of serum ionized calcium. A left craniotomy was performed and a fibroblastic meningioma of 5 cm in diameter was removed. Even though the patient's clinical condition was good, a calcium-phosphorus metabolism test confirmed high plasma levels of ionized calcium and parathyroid hormone. Thyroid and parathyroid ultrasonography revealed multinodular goiter and a parathyroid lesion confirmed by 99mTc-TCO4/99mTc-MIBI scintigraphy. A left superior parathyroidectomy and total thyroidectomy were performed. Histological examination revealed a parathyroid adenoma and a small papillary carcinoma of 0.4 cm in the right thyroid lobe. As far as we know, this patient is the third case of meningioma associated with parathyroid adenoma and papillary thyroid carcinoma described in the literature.
