Salivary Gland Myoepithelioma with Focal Capsular Invasion

Myoepithelioma of minor salivary gland--an immunohistochemical analysis of four cases.

INTRODUCTION AND METHODS We performed an immunohistochemical study in four cases of myopitheliomas with objective to realize a profile in respect of differentiation grade by the monoclonal antibodies CK14, vimentin and alph-SMA, besides to investigate the cell proliferation by anti-PCNA, besides, we compare the immunoreactive with glandular normal tissue. RESULTS In the glandular normal tissu...

Myoepithelioma of a minor salivary gland of the cheek: case report.

Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is...

Basal cell adenocarcinoma of the salivary gland: a morphological and immunohistochemical comparison with basal cell adenoma with and without capsular invasion

BACKGROUND It is often difficult to diagnose salivary gland tumors that exhibit basaloid features differentially. The aim of this study was to identify additional morphological and immunohistochemical characteristics that can aid the diagnosis of basal cell adenocarcinoma (BCAC) of the salivary gland. METHODS AND RESULTS In total, 29 basal cell neoplasms [eight BCACs, 11 basal cell adenomas (...

Predictors of Thyroid Gland Invasion in Laryngeal Squamous Cell Carcinoma

Introduction: Laryngeal squamous cell carcinoma (SCC) can invade the thyroid gland leading to unnecessary thyroidectomies with subsequent hypothyroidism and hyperparathyroidism. Thus, clinicopathological variables should be defined in order to predict thyroid gland invasion preoperatively.   Materials and Methods: We performed a retrospective analysis of 1,465 patients with laryngeal SCC referr...
