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.
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.
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.
72-year old woman noticed skin lesions at the internal orbital cantus of the right eye, diagnosed as infiltrating basocellular carcinoma with safe margins. The prognosis is good. A follow-up by a dermatologist is recommended.
51-year-old male with past medical history that is remarkable for Sino-nasal adenocarcinoma which was resected 13 years ago, and a recurrent local tumor which was re-operated. Since late 2007, the patient has been noticed to have mild macrocytic anemia and leucopenia, and the hematologist thought it might represent a myelodysplastic syndrome.
