52-year-old male was diagnosed in 2004 with a carcinoma of the lower rectum and underwent surgical anterior resection of the rectal tumor which was a well differentiated adenocarcinoma. In 2008 he underwent emergency operation for a perforated pyloric ulcer and then a radical resection of a gastric tumor which infiltrated the entire thickness of the gastric wall. It was a G3 diffuse type adenocarcinoma with signet ring cells, at pT3N2 stage.
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.
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.
7-year-old boy with prodrome of right-sided and right face weakness, gait ataxia, and intermittent headaches. Head computed tomography demonstrated a tumor at the brainstem/posterior fossa, and then MRI confirmed a diffuse intrinsic pontine glioma (a typical brainstem glioma). Following initiation of dexamethasone (Decadron, steroid for vasogenic edema), the child has started experimental treatment with the medicine nimotuzumab to be followed with conventional radiotherapy.
