Abstract
ABSTRACT Testicular cancers are classified in germ cell and non-germ cell tumors, as well as, liposarcomas. We report the case of a patient with a large testicular liposarcoma, submitted to surgical treatment with excision of scrotal pouch and segment of the spermatic cord, and the left testicle, showing a good evolution. This report presents one of the first cases of a sclerosing variant of well-differentiated testicular liposarcoma, large in size and with no association with another cancer. Due to their location, the diagnosis is difficult and unusual. Complete tumor resection and regular medical follow-up show a good prognosis, less recurrence, and little cellular differentiation.

The twenty-first century has brought in a new spectacular progress in the utility of muscle biopsy with the commencement of molecular methods
The molecular era was made possible by the development of molecular biology and its application to muscle diseases
Summary
The history of muscle biopsy dates back to 1860, when Duchenne first performed a biopsy on a patient with symptoms of myopathy[1]. The introduction of enzyme histochemical methods by Victor Dubowitz, in 1970, revolutionized the role of muscle biopsy in the diagnosis of various primary and secondary muscle diseases[2]. The adaptation of histo- and cytochemical techniques to the study of muscle biopsies improved diagnostic accuracy and enabled the identification of new changes and structures[3, 4].
