INTRODUCTION We report an observational study on the etiology and recurrence of acinic cell carcinoma of the parotid gland that seemed to be related to pregnancy. The medical literature has never reported such an association; therefore, our case report is probably the first to mention this observation. CASE PRESENTATION This report is of a 25-year-old Arabic female patient from the United Ara...

Abstract A basal cell ameloblastoma is an uncommon benign neoplasm and has a similar histological appearance to carcinoma of the skin. This clinical case report will discuss originating in maxilla baseloid variant. The objective highlight possibility misdiagnosis from this challenging case. 34-year-old male was referred maxillofacial department with recurrent nasal regurgitation following denta...

BACKGROUND Mucinous cystic neoplasm of the liver with extrahepatic growth is a rare benign epithelial neoplasm of the biliary system that presents with a mass effect or is incidentally found on imaging. The tumor affects mostly the common hepatic duct, which is difficult to diagnose preoperatively by radiology, endoscopy, or cystic fluid analysis. Endoscopic ultrasound is a noninvasive tool for...

Although the giant cell tumor of bone is generally classified as a benign tumor it can rarely metastasize and has a potential risk of local recurrence. We want to report about a female patient who suffered from a recurrence of a giant cell tumor of bone after the implantation of a total endoprosthesis of the knee joint. We have treated her with denosumab, which is a receptor activator of nuclea...

Proximal-type epithelioid sarcoma is a rare soft tissue neoplasm which arises from the more proximal part of body and occurs more often in young people; the definite diagnosis depends mainly on the pathological examination; early detection and complete excision remain the foundation of treatment. Due to its aggressive behavior, high capacity of recurrence and the great ability to metastasize, a...

The lesion traditionally known as odontogenic keratocyst has been renamed by WHO in 2005, as “keratocystic odontogenic tumor” as it is more appropriate and reflects its potential for local, destructive behavior. It is a benign intraosseous neoplasm of jaw, which is unusual due to its characteristic histopathological and clinical features, including potentially aggressive behavior, high recurren...

Angiomyxoma is a rare, slow-growing myxoid neoplasm that occurs almost exclusively in the genital, perineal, and pelvic regions of adult women. It mostly occurs during the reproductive years. It has propensity for local recurrence [1–4]. Macroscopically, they are soft, partly circumscribed, polypoids; across cross section, they have a glistening, homogeneous, gelatinous appearance; and sizes ra...

Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft tissue neoplasm of low-to-intermediate grade malignant potential. Childhood onset of DFSP is rare. It is most commonly seen on the trunk and proximal extremities. In children, a high index of suspicion is necessary to avoid delays in diagnosis that can lead to further morbidity. Here, we report a case of DFSP in a 9-year-old female chil...

Cystic lymphangioma mainly occurs in children. Cystic mediastinal lymphangioma (CML) originates from mediastinal tissues and is an extremely uncommon cystic lymphangioma that develops from the lymphatic vessels. The present study reports the case of 46-year-old male patient with a giant CML that was surgically resected by video-assisted thoracoscopy. The largest diameter of the CML was 18.0 cm,...
