Metastatic tumor is one of several etiologies of space-occupying masses in the orbit that accounts for 1-13% of all orbital masses. In the adult patient population, breast cancer is the most common tumor to metastasize to the orbit, followed by metastasis from the lung, prostate, and gastrointestinal tract. Carcinoid tumors are rare neuroendocrine neoplasms derived from enterochromaffin cells, ...

Let E be an optimal elliptic curve overQ of prime conductorN . We show that if for an odd prime p, the mod p representation associated to E is reducible (in particular, if p divides the order of the torsion subgroup of E(Q)), then the p-primary component of the ShafarevichTate group of E is trivial. We also state a related result for more general abelian subvarieties of J0(N) and mention what t...

Rare cases of carcinoid syndromes can develop from either gastrointestinal neuroendocrine tumors (NETs) without liver metastasis or large retroperitoneal involvement. We report a case patient with isolated flushing highly suggestive syndrome caused by an ileal NET adjacent lymph node metastases but no metastases. The final diagnose was delayed for this due to combination misleading clinical pre...
