70-year-old male underwent epileptic seizures. A brain CAT scan showed a space occupying lesion with surrounding edema in his left frontal lobe. A subsequent MRI examination enabled the demonstration of four separated lesions in his brain consistent with metastases. A total body CAT scan demonstrated a mass in the right lung. The diagnosis of poorly differentiated squamous cell carcinoma of the lung was established by bronchoscopy and transbronchial biopsy. The patient was treated by brain irradiation.
A 55 years old female was diagnosed with infiltrating ductal carcinoma of the right breast 7 years ago. The patient underwent a right quadrantectomy and axillary lymph nodes removal, adjuvant chemotherapy and radiation therapy. 5 years ago, after diagnostic finding of reappearance of infiltrating ductal carcinoma of the right breast, the patient underwent right mastectomy and revisional surgery of axillary armpit, and another adjuvant chemotherapy.
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.
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.
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 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.
