INTRODUCTION Non-Hodgkin lymphoma (NHL) can involve the paratesticular organs as the primary disease, as primary testicular lymphoma that secondarily involves the paratesticular structures, as the initial site of presentation of occult nodal disease or as the result of disease dissemination. Primary follicular lymphoma of the epididymis in an adult is extremely rare. Little is known about prima...

Paratesticular liposarcomas are rare tumors and are often reported as isolated cases. Patients usually present with a painless scrotal or inguinal mass, mimicking inguinal hernia. They refer to liposarcomas arising from the spermatic cord, testicular tunics, and epididymis. We report a case of bilateral scrotal swelling which was misdiagnosed as inguinal hernia. Intraoperative diagnosis of test...

BACKGROUND To report the cases of adenomatoid tumors seen at Hospital Universitario La Paz in the last 15 years. METHODS A clinical, pathological, and surgical study was conducted of males with testicular or paratesticular tumors with a histological report of adenomatoid tumor. RESULTS Among the nine cases studied, seven had paratesticular and two intratesticular adenomatoid tumors. Treatme...

Paratesticular cystadenocarcinoma is a rare form of ovarian epithelial tumor, with less than forty cases reported to date.1 Clinical presentation is scrotal enlargement with no significant pain.2 Ultrasound often shows a hypoechoic vascularized mass, with variable amounts of hydrocele. CT and MRI are not able to differentiate this tumor from other differential diagnosis. When normal values of h...

Paratesticular sarcomas have happened rarely. Due to the infrequency of this malignant disease and its diverse histopathologic subtypes, no standard treatment would be available. Multiple treatments have reported in literature with different results. We have reported a 55 years old man with a 30 years history of paratesticular mass. After multiple operations, radical orchiectomy has revealed li...

A case of paratesticular rhabdomyosarcoma is presented. An 18-year-old male was admitted with the complaint of giant scrotal swelling and abdominal fullness on September 5, 1986. Left radical orchiectomy was performed with the pathologic diagnosis of alveolar rhabdomyosarcoma. The tumor was paratesticular in location and had invaded a spermatic cord. Radiological examination showed a gross meta...

OBJECTIVES To report one case of metastatic paratesticular rhabdomyosarcoma in a 14 years old patient, classified as stage IIb (IRSG). METHODS After treatment with radical surgery (orchiectomy and lymphadenectomy), polychemotherapy and radiotherapy, showed good evolution initially. RESULTS 12 months after surgery the patient is disease free. CONCLUSIONS Adjuvant treatment is very importan...

Mesothelioma of the tunica vaginalis testis (MTVT) is a rare tumor that usually affects patients after the sixth decade of life. Exposure to asbestos is a known risk factor. Enlargement of the scrotal volume is the most common initial clinical manifestation, and about 15% of cases present metastasis at diagnosis. The treatment relies on surgical resection while the role of adjuvant chemotherapy...

Paratesticular fibrous pseudotumors (PFPs) are rare pathologies with quite wide and variable topographic-morphological features. It is difficult to distinguish PFPs from malignant masses. Treatment can be done by resection of the mass. We reported a young patient's findings about this rare pathology.
