Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm typically arising in the pleura and involving the orbit as its most common extra-pleural location. We herein describe a well documented case of orbital SFT arising in a 62-year-old woman presenting with progressive swelling of the right upper eyelid and proptosis.

We report on an 84-year-old man with a solitary, nodular lesion on the scalp. The patient had been previously submitted to electrodessications of the scalp due to multiple solar keratoses. Histopathologically, the lesion showed features of a high-grade conventional osteoblastic osteosarcoma involving the dermis. Computed tomography showed no involvement of(More)
The Notch signaling has been implicated in the regulation of self-renewal of adult stem cells and differentiation of precursors along a specific cell lineage, in normal embryonic development and organogenesis. There is also evidence that signaling through Notch receptors regulate cell proliferation and cell survival in several types of cancer, with opposing(More)
OBJECTIVE To facilitate development of novel disease-modifying therapies for lysosomal storage disorder (LSDs) characterized by nervous system involvement such as metachromatic leukodystrophy (MLD), molecular markers for monitoring disease progression and therapeutic response are needed. To this end, we sought to identify blood transcripts associated with(More)
Glandular hamartoma is an extremely rare congenital malformation of the larynx. Presenting symptoms result from airways obstruction and may include slowly rising respiratory distress, stridor, changes in voice, eating and activity levels.
