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.
36-year-old otherwise healthy female underwent routine tests that found atypical cells in Pap smear. Her cervix was biopsied, and found poorly differentiated neuroendocrine carcinoma. 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. In the expert's opinion the patient has locally extensive small cell neuroendocrine carcinoma of the cervix with extensive pelvic and PA adenopathy.
A 58 year-old woman who first presented for evaluation of a bleeding pigmented lesion on the back. An excisional biopsy was performed and revealed a nodular melanoma. A wide excision was performed and no residual melanoma was identified. After a sentinel lymph node biopsy found to be positive, a completion of node dissection was performed and on pathological evaluation, total 6 of 17 lymph nodes contained melanoma.
Staging studies included whole body PET/CT scan and a head CT. FDG uptake by PET was noted in the left axilla only, with no evidence of more distant metastatic disease.
69-year-old male found on colonoscopy to have multiple polyps and a rectal cancer. He underwent preoperative chemoRT, underwent resection and received a single cycle of bolus 5-FU with leucovorin. In early 2007, he had multiple complications and ultimately has a permanent ileostomy. Scans over the next few years have demonstrated nonspecific findings in his thorax however in July 2008 he had a mesenteric mass with adenopathy. These lesions had FDG uptake on PET scan.
An occasion chest X-ray of a 74-year-old female revealed a thickening in her left lung, and the tumor was latter typified as non-small cell lung cancer. Her staging chest CAT scan was consistent with a primary tumor in the lingular sub-segment together with millimetric parenchymal nodules suspected as secondary. She underwent a lingular segmental resection of the left lung. The histological report described a mixed acinar and non-mucinous bronchoalveolar adenocarcinoma of the lung.
74-year-old women with thickening in the left lung. The tumor was typified as non-small cell lung cancer (NSCLC) with millimetric parenchymal nodules suspected as secondary. She underwent a lingular segmental resection.
