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.
45-year-old male with stage 4 Adeno carcinoma of the lung. The tumor was found to obstruct the left superior lobe bronchus with subsequent subtotal athelectasis and retracted left hemi-thorax. The exam found diffuse thickening of the mediastinal pleura, lymphadenopathy and analogous formations of probable secondary nature. In the expert's opinion, if the patient is already at stage IV, he should not undergo surgery. He recommends combined endobronchial and external irradiation together with chemotherapy.
