66-year-old female was diagnosed, following persistent cough, with non-operable tumor of her lung with satellite nodules, and chemotherapy was initiated (first Cisplatin and Gemcitabine, and then switched to Tarceva). Response evaluation following the fourth cycle of chemotherapy showed either stability or an initiation of tumor response, but bone scintigraphy that was performed 6 months later revealed an area of increased uptake in the left hemithorax which could be suggestive of a secondary bone lesion.

66-year-old female was diagnosed, following persistent cough, with lung tumour with concomitant pulmonary nodules and a measurable enlargement of lymph nodes. FBS was positive for well differentiated neuroendocrine carcinoma and a needle biopsy revealed adenocarcinoma with associated neuroendocrine differentiation.

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.

75-year-old male with a cutaneous squamous cell carcinoma resected from the right eyebrow in 2003. In 2006, the patient underwent resection of an ipsilateral squamous cell carcinoma in the parotid bed that was presumably a nodal metastasis. He then experienced local relapse treated with resection and adjuvant radiotherapy. There was recurrent disease involving the right cheek excised in 2008. In 2009, another recurrence led to resection with orbital exenteration. Pathology showed squamous cell carcinoma, with perineural invasion, and extension into the orbital muscles.

33-year-old female was diagnosed with multiple endocrine neoplasia of the pancreas. She underwent removal of the pancreatic lesion and lymph node dissection, another surgery to remove the distal pancreas and spleen, and parathyroidectomy, but the Octreoscan revealed recurrence.  

66-year-old female was diagnosed with lung tumour within the right hemithorax with concomitant pulmonary nodules and a measurable enlargement of lymph nodes. FBS was positive for well differentiated neuroendocrine carcinoma and a needle biopsy revealed adenocarcinoma with associated neuroendocrine differentiation. The patient was then treated with altogether four courses of induction chemotherapy.

72-year-old female with elevated levels of the tumour marker CA 19-9 but none of the diagnostic tests showed any tumour finding. The levels of CA 19-9 remained in the pathologic range, although with decreasing values. Currently, the patient is not reporting any significant symptoms.
