Salivary gland neoplasm (SGN) is one of the largest groups of neoplasms, with over 3 dozen benign and malignant tumors in the 2005 WHO classification and with additional entities recognized during the last decade. Current success of fine needle aspiration biopsy (FNAB) in SGN diagnosis is largely because of its high sensitivity and specificity in: 1) distinguishing neoplastic from non-neoplasti...

OBJECTIVE To describe the diagnostic cytologic features of low grade papillary adenocarcinomas of minor salivary gland origin (LPA) along with its pertinent differential diagnostic entities. STUDY DESIGN The study was based on a histologically confirmed case of LPA that recurred after multiple excisions. Fine needle aspiration (FNA) was performed during the most recent recurrence. RESULTS L...

AIM The purpose of this report is to present the clinical and histological features of a canalicular adenoma (CA) occurring in the upper lip and vestibular fornix of a 62-year-old woman. BACKGROUND CA is an uncommon benign salivary gland tumor occurring almost exclusively in the intraoral glands. This tumor has often been referred to as a variant of the basal cell adenoma. However, the World ...

Basal cell adenoma is an uncommon benign epithelial neoplasm of salivary gland which derives its name from the basaloid appearance of tumor cells and accounting for 1-2 % of all salivary gland epithelial tumors. This tumor usually arises in the major salivary glands, with the parotid being the most frequent site of occurrence, followed by the upper lip; while it is very rare in the minor saliva...

background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...

BACKGROUND AND PURPOSE Parotid gland BCA is a rare benign tumor. Only a few studies describing the imaging features of BCA have been published. This study investigated CT and sonography characteristics of BCA of the parotid gland. MATERIALS AND METHODS Demographics of patients with BCA were evaluated, and lesion characteristics of CT (n = 22) and sonography (n = 20) were reviewed. These cases...

Basal Cell Adenocarcinoma (BCAC) is a rare tumour of the salivary glands which has recently been included in the World Health Organization classification. It is thought to be malignant counterpart of basal cell adenoma (BCA) from which it can only be distinguished on the basis of its infiltrative growth pattern and lymphovascular and perineural invasion. Other important tumours like adenoid cys...

Myoepithelial carcinoma, the malignant counterpart of benign myoepithelioma, is one of the rarest salivary gland neoplasms. It is composed almost exclusively of tumour cells with myoepithelial differentiation, characterized by infiltrative growth and potential for metastasis. We herein, report a case of myoepithelial carcinoma in a 50 years old male with reticular morphology. Reticular variant ...

basal cell carcinoma (bcc) is the most common cancer of the skin. definite diagnosis usually requires histological examination but recently it has been suggested that cytological examination of skin smear can be used as an alternative. to evaluate sensitivity and specificity of cytological examination, a total of 125 skin lesions, clinically suspected to be bcc were studied. cytological samples...
