A Rare Case of Primary Histiocytic Sarcoma of the Stomach.

Histiocytic sarcoma is a rare lymphohematopoietic malignancy with aggressive clinical course and poor therapy response. The diagnosis relies on the confirmation of its histiocytic lineage and exclusion of other poorly differentiated tumors. Most of the cases present in extranodal sites, but primary gastric involvement is exceptional.

Clinical application of SPECT-CT with 99mTc-Tektrotyd in bronchial and thymic neuroendocrine tumors (NETs).

Neuroendocrine tumors (NETs) of the thorax including bronchial and thymic tumors belong to foregut NETs. Limited loco-regional thoracic NETs can be resected with surgery, but in extensive metastatic disease the treatment is mainly palliative. A high incidence and density of somatostatin receptors (SSTR2, SSTR3, and SSTR5) are found in thoracic NETs.
