Low-grade cribriform cystadenocarcinoma (LGCCC) is a rare tumor of the salivary gland that most often arises from the parotid gland. A 51-year-old man developed a small mass on the right parotid gland 5 years ago. A preoperative magnetic resonance image showed abnormal intensity, an atypical characteristic for such a tumor; therefore, the diagnosis was difficult. Thus, a superficial parotidectomy was performed as a total excisional biopsy to remove the tumor. Histopathological analyses revealed that the tumor was composed of a single cyst comprising cells containing mucosal fluid, with proliferation of large cells...

Non-Hodgkin's lymphoma on the parotid gland is a relatively rare occurrence among head and neck tumors. The mass of parotid gland lymphoma cannot be distinguished from other benign masses of the parotid gland; therefore, it is important to consider lymphoma in the differential diagnosis when examining parotid swellings and masses. Parotid gland lymphoma is most likely to be B-cell, non-Hodgkin's lymphoma of one of three types, which include follicular, marginal zone, and diffuse large B-cell, although other histologic patterns have been described...

Prevention of implant-associated infections at an early stage of surgery is highly desirable for the long-term efficacy of implants in dentistry and orthopedics. Infection prophylaxis using conventional antibiotics is becoming less effective due to the development of bacteria resistant to multiple antibiotics. An ideal strategy to conquer bacterial infections is the local delivery of antibacterial agents. Therefore, antimicrobial peptide (AMP) eluting coatings on implant surfaces is a promising alternative...

A functional superficial parotidectomy can maintain salivary function by preserving the Stensen duct. However, this technique still brings the possibility of salivary leakage, because major branches of the parotid duct from the resected site do not get ligated. To reduce this complication, this study introduces a modified technique with major branch ligation. From December 2008 to February 2015, 14 patients who underwent superficial parotidectomy were divided into 2 groups. Group A was treated with the modified functional superficial parotidectomy involving the major branch between the superficial lobe and parotid duct...

INTRODUCTION: Sialendoscopy has changed the management of obstructive sialadenitis. Nowadays, minimally invasive techniques evolve to preserve salivary gland function. Intraductal lithotripsy allows stones fragmentation and retrieval without opening the salivary duct. We report our experience with the StoneBreaker (SB), a new lithotripter with improvement using a sterile bag that permits reuse of the SB without passing to sterilization. TECHNICAL NOTE: The non-sterilized SB was used into a sterile camera sleeve in 5 patients, 3 submandibular lithiases and 2 parotid lithiases...

INTRODUCTION: Minimally invasive techniques (MIT), including sialendoscopy, extracorporeal lithotripsy and intraoral approach, have to be preferred in parotid stones removal. In case of MIT failure, a combined intra- and extra-oral approach can be achieved. The aim of our study was to evaluate the efficacy and the complications of these combined approaches. MATERIALS AND METHODS: A retrospective study has been conducted on patients treated between 2006 and 2015...

Melanotic neuroectodermal tumor of infancy is a rare congenital pigmented neoplasm of neural crest origin, locally aggressive, growing rapidly and developing during the 1st year of life. It most commonly arises from the maxilla, cranial vault, and mandible. Occasionally, it exhibits malignant behavior with local lymph nodes involvement. Cases misdiagnosed and left untreated for a long time can present challenges due to the tumor mass and infiltration. In these cases, adjuvant chemotherapy can be extremely helpful before radical excision...
