Metastatic hepatocellular carcinoma of the parotid region without lung metastasis: a case report
2009
Parotid gland metastatic tumours are rare, usually arising from a primary mucosal or cutaneous cancer located in the ipsilateral head and neck region, although metastases from a primary cancer outside the head and neck region are possible. Hepatocellular carcinoma (HCC) rarely metastasizes to the head and neck region and the parotid glands are an even more unusual site. The authors describe the case of an 82-year-old male who presented with a right parotid mass. Percutaneous incisional biopsy with histological and immunohistochemical studies suggested metastatic HCC. Radiological investigations excluded other metastatic lesions. This case illustrates the difficulties that may be encountered…
Mandibular solitary plasmocytoma of the jaw: a case report.
2010
Plasma cell tumors are lymphoid neoplasms with an uncontrolled proliferation of B cells. These are divided into localized forms (solitary bone plasmocytoma -SBP- and extramedullary plasmocytoma -EP-) and disseminated forms (multiple myeloma-MM-). The SBP is a rare and controversial disease. The aim of this article is the analysis of this entity based on the presentation of a 64-year-old man without previous medical history, with a mass in the left mandibular angle extending to the parotid region on the same side. The panoramic radiography, computed tomography and magnetic resonance imaging showed an osteolytic lesion 6.5 x 5 x 6.7 cm in the mandibular angle with infiltration of the masticat…
Cavernous hemangioma of the parotid gland in adults
2014
Hemangiomas account for 0.4-0.6% of all tumors of the parotid gland and most of them occur in children, nevertheless in adults hemangiomas are very rare. We report the case of a 62 year old woman with a mass in the parotid right tail associated with fluctuating swelling episodes unrelated to meals and with a slowly progressive growth. The provisional diagnosis was a pleomorphic adenoma, so a right superficial parotidectomy was performed. During surgery, the macroscopic appearance makes suspect a vascular lesion. The histopathological result was a cavernous hemangioma. The classic clinical presentation of a parotid hemangioma is an intraglandular mass associated or not with skin lesions char…
