The transcription factor LMO2 is involved in vascular and hematopoietic development and hematolymphoid neoplasia. We have demonstrated that LMO2 is expressed nearly ubiquitously in native and neoplastic vasculature, including lymphatics. LMO2 reactivity is otherwise virtually absent in nonhematolymphoid tissues except in breast myoepithelium, prostatic basal cells, and secretory phase endometri...

Solid variant aneurysmal bone cyst is a rare benign bone lesion, representing a small fraction of all aneurysmal bone cysts. The imaging appearance and histologic features may overlap with other benign and malignant neoplasms, posing a diagnostic dilemma for clinicians, pathologists, and radiologists. We present a case of solid variant aneurysmal bone cyst of the distal fibula and review the ra...

Salivary  gland  tumors  accounts  for  less  than  1%  of  all  tumors.  Minor  salivary  gland  tumors (MSGTs) are uncommon and make up about 10% of all salivary gland neoplasms. The clinical and histopathological distribution of these tumors vary geographically. A case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. The tumor invaded into the anterior ...

Angiosarcoma is a rare tumor of bone that uncommonly involves the skull. Primary neoplasms of the skull represent 2.6% of primary neoplasms of bone. We wish to report a case of angiosarcoma of he skull in an 18-year-old pregnant woman who presented with a rapidly growing left frontotemporal mass. Neuroimaging revealed a left frontotemporal mass with destruction of diploic space ...

Multiple myeloma (MM) or plasma cell myeloma is a neoplastic proliferation of plasma cells that primarily involves the bone marrow but may originate from extramedullary sites [1-4]. Although it is uncommon in veterinary medicine, it has been reported in several species, in‐ cluding cats, dogs and, horses [1,3,5-10]. The frequency of MM in cats is slightly <1% of all malignant neoplasms. Canine ...

BACKGROUND Werner syndrome (WS) is an autosomal recessive genetic instability and progeroid ('premature aging') syndrome which is associated with an elevated risk of cancer. OBJECTIVES Our study objectives were to characterize the spectrum of neoplasia in WS using a well-documented study population, and to estimate the type-specific risk of neoplasia in WS relative to the general population. ...

salivary  gland  tumors  accounts  for  less  than  1%  of  all  tumors.  minor  salivary  gland  tumors (msgts) are uncommon and make up about 10% of all salivary gland neoplasms. the clinical and histopathological distribution of these tumors vary geographically. a case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. the tumor invaded into the anterior surf...

Objectives: The aim of this study was to review major temporal bone cases performed by one surgeon, and to highlight pitfalls and progress in the surgical management of previously “unresectable” neoplasms. Design: Retrospective case series review. Setting: Tertiary referral center. Participants: Nine patients who underwent total en bloc temporal bone resection for malignancy of the ear and temp...
