Background: Urothelial carcinoma of the bladder is common cancer. Despite advances in treatments and introduction immune checkpoint inhibitors recent years, metastatic disease carries a poor prognosis
Introduction: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. Case Report: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, ...
Pilomatrix carcinoma is a very rare adenexal tumor which originates in the hair matrix cells and is marked by exophytic growing and common local recurrence, but the metastatic potential is limited. It was first described in 1980 by Lopansri and Mihm, and since then about 90 cases have been reported in the literature. There is no established treatment for the wide local invasion and metastasis o...
Acinic cell carcinoma (ACC) is an uncommon salivary gland neoplasm that generally displays an indolent growth pattern. Most cases arise in the major glands, particularly the parotid. However, it can arise from minor salivary glands in the oral cavity and aero-digestive tract. Although ACC is generally a low-grade malignant tumor, poorly differentiated and high-grade transformed variants exhibit...
UNLABELLED In squamous cell carcinoma of the head and neck, staging of the neck cannot rule out occult metastatic disease. An improved staging is necessary to avoid elective neck dissection in patients staged as N0. The study was performed to determine the feasibility of the detection of occult metastatic disease by ultrasound-guided fine-needle aspiration cytology (USgFNAC) of sentinel lymph n...
INTRODUCTION Metastatic tumors to oral cavity and jaws are rare, and mandible is the most commonly involved location. Because the most common jaw symptom is pain, these lesions could be misdiagnosed as pathologic entities with dental origin. In this article a case of metastatic breast carcinoma initially diagnosed as pulpal/periapical disease is presented and discussed. METHODS A 40-year-old ...
