Introduction Lipomas are common benign soft tissue neoplasms composed of mature white adipocytes. They are the most common soft tissue mesenchymal neoplasms. However, they are relatively uncommon in the oral and maxillofacial regions. Their overall incidence in the oral cavity is thought to be between 1% and 4% of all benign oral lesions. Specific anatomic locations within the oral and maxillof...

Eccrine syringofibroadenoma (ESFA) is a rare neoplasm that usually presents as a solitary, often large, hyperkeratotic nodular lesion with predilection for the extremities. Histologically, there are thin anastomosing epithelial cords and strands forming a lattice and connected to the undersurface of the epidermis. Ducts are presented within the tumor. Between the strands, there is a rich fibrov...

We report a 50-year-old woman with no relevant clinical history who presented with headache and loss of memory. Magnetic resonance imaging showed a left parieto-temporal mass with annular enhancement after contrast media administration, rendering a radiological diagnosis of high-grade astrocytic neoplasm. Tumour sampling was performed but the patient ultimately died as a result of disease. Micr...

Myxoid adrenocortical neoplasms are rare; to our knowledge, only 56 cases have been reported in the literature. Therefore, distinguishing benign from malignant cases is challenging. Although the histopathological features of myxoid adrenocortical neoplasia have been amply demonstrated, their imaging characteristics are yet to be reported. We describe here these characteristics for such a neopla...

BACKGROUND Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established. OBJECTIVE To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients. METHOD We retrospectively studied histologically proven cases of eccrine poroma from three Mexican hospitals analyzed by...

Although some clinical and radiological features may predict malignancy presence in intraductal papillary mucinous pancreas neoplasms, preoperative diagnosis remains difficult. In this study we present 7 patients with Intraductal Papillary Mucinous Neoplasm (IPMN) studied both with 18FDG-PET and magnetic resonance cholangiopancreatography (MRCP). A focal hypermetabolism was documented in 2 pati...

Background: New onset and active Systemic Lupus Erythematosus (SLE) may be infrequently associated with diffuse lymphadenopathy. This is often worrisome for malignancy in which F18/FDG PET scanning is typically obtained as part of a neoplastic workup. Results are often difficult to interpret and resemble lymphoma in many instances. There is sparse literature describing systematic differences in...

Primary neoplasms of the pleura are rare tumors and the majority are generally mesotheliomas. Mesotheliomas are either localized and mostly benign, or diffuse and uniformly malignant neoplasms. Localised benign pulmonary mesothelioma (solitary fibrous tumor of the pleura) are originally thought to be a variant of diffuse pleural mesothelioma because they consists of a spindle cell stroma associ...

CONTEXT Solid and cystic papillary neoplasm of the pancreas is an extremely rare neoplasm that mostly affects young females in the mean age of 25 years and accounts for about 0.2-2.7% of all pancreatic tumors. CASE REPORT A 18-year-old female presented with progressively increasing mass in the left hypochondrium and epigastric regions and vague abdominal pain. There was no history of jaundice...
