The highest incidence of papillary thyroid microcarcinoma in an autopsy series was reported by Harach et al. in 1985, who found 36 of 101 consecutive autopsies to have an incidental microcarcinoma. BACKGROUND: Papillary tumours of the breast are diagnostically challenging lesions and represent a wide spectrum of diseases from papilloma to invasive papillary carcinoma. (a) Tall cell variant papillary thyroid carcinoma with a trabecular growth pattern. calculated disease-related mortality and recurrence rates for both Extrathyroidal extension was more frequent in DSV than in TCV and cPTC patients (p < 0.05); moreover, only DSV tumors had a higher rate of recurrent/persistent disease when compared to cPTC treated with the same protocol (total thyroidectomy followed by 131I treatment) (p < 0.01). A rare subtype of breast papillary tumour resembling the tall cell variant of thyroid papillary … This is largely due to the tendency for TCV to present at an older age and with extrathyroidal extension (ETE). 2010 Dec;20(12):1341-9 Extrathyroidal extension and lymphovascular invasion were seen in 9 (33%) and 4 (15%) tumors, respectively.

T he tall cell variant (TCV) of papillary carcinoma of the thyroid was first described in April 1967, by Hazard) Since that time, 3 major series of TCV cases have been reported in the pathology and endocrine literature, the largest consisting of 18 cases.2-4 In addition, 4 individual case reports have been published,5"8 for a grand total of 51 cases of TCV. TCV and DSV patients were first risk stratified for recurrent/persistent disease without considering the histotype as a risk factor and subsequently, 6-24 months after initial treatment, re-classified on the basis of the response to therapy (ongoing risk stratification).
