Liposarcoma is a mesenchymal origin tumor that commonly occurs in the retroperitoneum; It is slow growing and its ability to produce metastasis depends on its

histological type. The purpose of this work is to present a case of simultaneous paratesticular liposarcomas with different histological types, in an 80-years-old male patient with a health history and low socioeconomic level; For two years he had been experiencing an increase in volume in the left inguinal region and ipsilateral testicle, which at first was painless; Then, as it increased in size, it became painful, covering the

entire right inguinoscrotal region. Physical examination, including transillumination sign, was negative. The analytical study only showed erythrocyte sedimentation rate at 95 mm/h and LDH at 650 U/l; The testicular ultrasound showed heterogeneous, solid and hyperechoic mass, with a fatty inguinoscrotal appearance and measuring more tan 30 cm, without the testicle being observed. Tumor excision was performed and three liposarcomatous tumors were found, two of them with similar histopathological characteristics and the other with a different histological pattern. After the surgical treatment, the patient recovered satisfactorily and has not had a recurrence according to the periodic controls carried out. The publication of the case was considered because liposarcomas can be confused on clinical examination with the presence of an inguinal hernia with fatty content with symptoms similar to these; Therefore, a thorough clinical examination must be performed to make a correct diagnosis. The histopathological study confirmed the diagnosis of the disease; which, in addition, revealed the presence of three liposarcomatous tumors and two histopathological variants of the same, from which no reports were found in the reviewed literature.
