BACKGROUND Adenomatoid tumor is one of the most common histological subtypes of paratesticular cancer arising from the epididymis. In very rare cases, these tumors appear as intratesticular lesions originating in the tunica albuginea, representing a diagnostic challenge. CASE PRESENTATION We present a case of a 51-year-old man with a small (0.9 cm) hyperechoic lesion of the left testicle mimi...

Adenomatoid tumors are rare benign neoplasms considered of mesothelial origin. They are usually asymptomatic and slow growing masses. They account for 30% of paratesticular tumors and very rarely involve the testicular parenchyma. Only ten such cases have been reported in the literature so far. Ideal treatment should be excision of the tumor avoiding orchidectomy. Nevertheless, because of the r...

The adenomatoid tumor of the epididymis (EAT) is a neoplasm located in the paratesticular region. Mesothelial origin has been mentioned and inflammation has played some role in the development of these tumors. Physical examination and testicular ultrasound constituted important tools in the diagnosis. Some reports have mentioned malignant behavior, but it is very rare. Surgical treatment is the...

There is no established treatment for advanced rhabdomyosarcoma (RMS) with metastases at the time of diagnosis. A 17-year-old male was referred to our hospital because of a right scrotal mass. Computed tomography showed multiple lung metastases with pleural effusion and retroperitoneal lymph node metastasis, and bone scintigraphy revealed multiple bone metastases. Right high orchiectomy was per...

A 78-year-old male patient presented with an inguinoscrotal nodule that had lasted for 3 years. The patient reported a past medical history of hydrocele formation. The final diagnosis was fibrous pseudotumor of the paratesticular region, which was based on a histopathological examination and immunohistochemical findings. The aim of this case report is to spread awareness and recognition of neop...

Paratesticular leiomyosarcoma is a rare neoplasia, which has been reported in less than 100 cases so far. According to its prevalence, this neoplasia is originated from testicular tunica (48%), spermatic cord (48%), epididymis (2%) and dartos muscle, as well as subcutaneous tissue of scrotum (2%).(1,2,3) This lesion is seen in all age groups. However, it is mostly diagnosed in the 6th decade an...
