An 83-year-old man with left lower back pain was found to have a 5 cm mass in contact with the right adrenal gland and a 12 mm left ureteral stone by abdominal plain computed tomography. An abdominal plain magnetic resonance imaging T2-weighted image revealed a heterogeneous high signal mass in the right adrenal gland. Pheochromocytoma, adrenal carcinoma, and retroperitoneal neurogenic tumor were suspected. Tumor markers and endocrine examinations were within standard values. Laparoscopic right adrenalectomy was performed. A 4×3.6 cm, 62 g solid tumor was found in contact with right adrenal gland. Histopathologically, hobnail-like vascular endothelial cells were found in the tumor, but no malignant findings such as multi-layered vascular endothelial cells and nuclear atypia were observed. This tumorwas diagnosed to be an anastomosing hemangioma.

A 53-year-old man visited a doctor due to left inguinal enlargement. He was diagnosed with left inguinal hernia with omentum as the content by a computed tomography (CT)scan. He underwent open inguinal hernia repair ; however, an inguinal tumor was diagnosed intraoperatively and was resected as much as possible. Although the tumor resection was macroscopically incomplete, he was followed up without any treatment because the tumor was histologically diagnosed as lipoma. Sixteen months after surgery, a 15 cm inguinal mass and a 7 cm left intrascrotal mass were detected by follow-up CT, and he was referred to our hospital. He underwent open surgery for wide excision of the tumor with a diagnosis of spermatic cord liposarcoma and left hydrocele of testis. The spermatic cord tumor was histologically diagnosed as well differentiated liposarcoma. He has been alive without recurrence for more than 10 months after surgery. It is sometimes difficult to distinguish a spermatic cord liposarcoma from inguinal hernia by imaging examinations.
