T-cell-rich B-cell lymphoma is a neoplasm recognized in humans in which a neoplastic proliferation of large B lymphocytes is present amid a background of reactive T lymphocytes. A 13-year-old Domestic Shorthair cat developed a mass in the region of the left parotid gland. Histologically, the mass was composed of scattered large atypical cells within a dense background of uniform small lymphoid ...

Malignant epithelioid hemangioendothelioma (MEH), also known as high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy originally described as a vascular neoplasm of endothelial origin. This very rare vascular neoplasm has been described mainly in soft tissue, but also in various organs and locations, including the liver, lung, brain, colon, lymph nodes,...

Introduction: Salivary gland Fine Needle Aspiration Cytology is a well-established pre-operative diagnostic tool done routinely worldwide. Heterogeneity of salivary lesions makes cytology diagnosis challenging for most cytopathologists. Milan system reporting six tier developed to minimize inter-observer variability, thus enhance reproducibility cyto-diagnosis.
 Aims: To study utility Syst...

Abstract Introduction: Polymorphous low grade adenocarcinoma (PLGA) is a rare salivary gland neoplasm with an indolent course. It occurs primarily in the minor salivary glands but can rarely occur in the major salivary glands. It usually occurs in the fifth to seventh decades of life with female preponderance.   Case Report: A 16-year-old male presented with recurrent painless swelling in the r...

Objective To determine whether the use of in-office ultrasound (US) by a head and neck surgeon is a useful adjunct to clinical assessment of parotid lesions and decrease the need of additional imaging, such as magnetic resonance imaging (MRI) or computed tomography (CT). Study Design Case series with chart review. Setting Tertiary care academic center. Subjects Seventy patients presenting with ...

Pleomorphic adenoma is the most common benign parotid gland tumor. Although its local recurrence rate is known to be high, the recurrence extending to the cervical region is rare. Here we report a case of a young female (25 years old) with pleomorphic adenoma of the parotid gland which showed multiple recurrences through facial to cervical regions over a span of eight years. We also discuss how...

Neoplasm of salivary glands constitutes about 3% of all tumours of head and neck. Within the category we can differentiate tumours of a very different histological structure. What lies behind such great differences in the changes within the salivary glands is complex embryogenesis of the glands. About 80% of all tumours of salivary glands is located in parotid gland, from 10 to 20% - in submand...

INTRODUCTION Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total paro...

BACKGROUND Our aim was to review the presentation, treatment, and outcome of patients with metastatic cutaneous squamous cell carcinoma involving the parotid gland at a tertiary referral center. METHODS We performed a retrospective chart review of the cancer registry at the Princess Margaret Hospital, Toronto, from 1970 to 2001. All patients had a previously untreated metastatic cutaneous hea...
