Three Cases of Sub-scalp Tumor Presenting with Protrusion of the Head

Yasuji Miyakita and Soichiro Shibui

Neurosurgery Division
National Cancer Center Hospital
Tokyo, Japan

Case 1 was an 81-year-old male who underwent right nephrectomy for renal cell carcinoma 5 years ago. When he fell down and hit his back of the head, he noticed an occipital lump (Fig. 1). The bulging was growing gradually within several months. He underwent an excisional biopsy and pathological findings showed a metastatic tumor from renal cell carcinoma. Irradiation was administered. Case 2 was a 58-year-old female who suffered head trauma 3 years ago. She noticed a protrusion on her parietal cranium while grooming her own hair (Fig. 2). She received a needle biopsy and the pathological diagnosis was meningioma. She underwent surgical resection of the tumor and cranioplastic surgery. Case 3 was an 81-year-old male who had tingling-numb on his forehead for 6 months. Because of the persistent dysesthesia accompanied by progressive swelling (Fig. 3), he consulted our hospital and was operated on for histological confirmation. Obtained tissues were composed of poorly differentiated carcinoma. He subsequently received irradiation on the frontal lesion.
