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.
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.
39-year-old male was diagnosed to have a neuroendocrine tumour with synchronic liver metastases. The disease was treated with an etoposide-carboplatin combination, Interferon A, somatostatin analogue and Zebra fish egg derived dietary supplements. In early 2008, a tumour progression was noted in that the disease started to produce the epithelial tumour markers CEA and CA 19-9.
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.
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.
