The finding on imaging (computed tomography scan or magnetic resonance imaging) of synchronous malignant renal mass in patient with an active nonrenal malignancy without renal specific symptoms is not frequent and diagnostic evaluation can be challenging. We describe a 54-year-old Moroccan male former chronic smoker who presented to our hospital with dry cough and impairment of the performance status. The imaging found a tumor mass in the left upper lobe of the lung associated to mediastinal lymph node and a scanno-guided biopsy of this tumor showed a non small cell lung cancer. The radiological staging revealed a solitary renal mass in the right kidney. The patient received firstly two cycles of a lung cancer chemotherapy with a partial response in the lung and a stability of the renal mass. Consequently, he underwent a scanno-guided biopsy of this mass which confirmed a synchronous clear cell renal carcinoma. The patient got chemo radiotherapy for the lung cancer and then after that he got a partial nephrectomy. He is still under a good control with more than 2 years after the initial diagnosis.

Weight loss is not a good clinical parameters for predicting an increase of setup errors. Other clinical and/or anthropometrical features should be prospectively evaluated in order to assess the need for re-planning.

Clear cell carcinoma is a rare minor salivary gland neoplasm. Its occurrence in the nasopharynx is uncommon. A limited number of cases are reported in the literature. Here, we report an additional case of clear cell carcinoma of the nasopharynx managed by induction chemotherapy followed by chemoradiotherapy, and we describe the clinical presentation, pathological features, and outcome. A 63-year-old man presented with an exophytic, ulcerative, and easily hemorrhagic tumor on the left side of the nasopharynx. A diagnosis of primary, cT4N0M0, clear cell carcinoma of the minor salivary gland was confirmed by a core needle biopsy through nasopharyngoscopy and staging procedures. The patient was treated by induction chemotherapy followed by concomitant chemoradiotherapy with clinical benefit and disease stabilization. Primary salivary gland clear cell carcinoma of the nasopharynx is uncommon. A definitive diagnosis requires an appropriate workup. The optimal treatment is unclear. Chemoradiotherapy might be a good option to manage such cases.

A patient aged of 70 years old presented a 6 months history of a right nasal bleeding and blockage. He was diagnosed with mucosal malignant melanoma. Loco regional extension in the CT and MRI showed involvement of the frontal sinus, sphenoidal sinus and suspected involvement of the medial wall of the orbit. He had surgical excision with removal of the tumor. Given the positive margins, adjuvant radiotherapy was indicated. The radiotherapy was delivered with intensity modulated radiation therapy (IMRT) technique in order to overcome anatomical complexity of the region, cover the tumor bed and preserve the organs at risk. Despite advances in techniques, there is still no impact on the overall survival.
