36-year-old otherwise healthy female presented with an atypical pap smear. Biopsy of cervix revealed poorly Differentiated Neuroendocrine Carcinoma. Immunohistochemical staining showed the cells positive for NSE, SYN, CHR, and 90% positive for Ki67 (proliferative index). The findings of the PET-FDG test showed pathological absorption of FDG as a primary tumor of the cervix, towards the left side of the body. Moreover, evidence is seen of nodal metastatic spread in the retroperitoneum and pelvis, mainly on the left.
A 74 years old male was diagnosed 3 years ago with non small cell lung carcinoma. Accordingly, it was decided that no chemotherapy should be given at that stage. Year and a half later, a new SOL was found in right lung, and right pneumonectomy was performed. On pathology a well to moderately differentiated adenocarcinoma was found. Lymphatic invasion was identified in lung and mediastinum. A revision on previous specimen was performed and it was concluded that the tumor was morphologically different from the previous specimen.
65-year-old male experienced loss of consciousness, and a CT scan showed a left temporal mass which was confirmed by MRI. The patient underwent Stereotacti biopsy of mass, and Histological examination gave a diagnosis of anaplastic astrocytoma. He started chemoradiation with fotemustine (nitrosourea alkylating agent). Repeated MRI showed progression with mass effect, mild uncal herniation and enlarging ventricles. He has stable expressive aphasia and hemisyndrome, lethargy and decreased motivation. His treatment was switched from phenobarbital to levetiracetam.
