متن کاملOrbital involvement with desmoplastic melanoma.
A 79-year-old woman developed an orbital mass five and a half years after excision of a cutaneous melanoma from the side of the nose.

متن کاملPseudoachalasia: a diagnostic challenge
Here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss.

The stenosis was treated by dilatation and abdomino pelvic comput...
