We report on a 50-year-old male patient who presented with a scrotal mass which he had noted two years earlier. Ultrasound revealed a well-defined, regular, paratesticular mass. Pathological examination of the surgical specimen revealed abundant lipoblasts and a stroma with myxoid changes, prompting a diagnosis of myxoid liposarcoma of the spermatic cord. Liposarcoma is a rare tumor of the spermatic cord which frequently metastasizes to the lumbar retroperitoneal lymph nodes. The foregoing characteristic and the histologic features of the tumor type influence treatment.

A case of carcinoid tumor of the appendix with "signet ring" cells pattern and asymptomatic clinical course is presented. The tumor was detected during a Bilroth I gastrectomy procedure. Mucin-secreting cells with cytoplasms often containing argentaffin and argyrophil granules was the predominant histologic pattern. Lack of neuron-specific enolase activity and their positivity for lysozyme and EMA marker indicate an origin from crypt cell and not a neural crest source. After simple appendectomy, the patient was healthy 3 years following surgery.
