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.
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.
