OBJECTIVES To review our 10-year experience with uncommon testicular tumours in children (prepubertal testicular and paratesticular), to review previous reports, and to determine the appropriate management of these rare tumours, specifically the role of testicular-sparing surgery. PATIENTS AND METHODS We retrospectively reviewed all cases of testicular tumours managed at our institution betwe...

Primary tumors of the epididymis are rare. Adenomatoid tumors are benign, usually found within the wall of fallopian tubes or beneath the uterine serosa. They are most frequently diagnosed as benign tumors of the epididymis and represent 30% of paratesticular tumors. The origin of this tumor is mesothelial cells. Leiomyoma are less common in the paratesticular localization. The origin of this t...

Paratesticular malignant fibrous histiocytoma is an extremely rare malignancy of the scrotum. This malignancy has rarely been described in the literature and scant information exists on the optimal management of this cancer. We present here a case of a 57-year-old man with a diagnosis of high-grade malignant fibrous histiocytoma of the left intrascrotal region who underwent radical orchiectomy,...

Leiomyomata of the urinary and male genital tract are extremely rare. They have been reported throughout the genitourinary male tract and the most common localization is the renal capsule. However, leiomyomas of the epididimis, spermatic cord, tunica albuginea and testis have been reported. We report diagnostic confirmation of a paratesticular leiomyoma in an azoospermic patient undergoing a te...

Fibrous pseudotumors of the testicular tunics and paratesticular tissue are uncommon lesions. They typically arise as painless scrotal masses that may be associated with hydrocele or history of surgery, trauma, or infection. Although benign, these lesions often clinically indicate malignancy and usually remain undiagnosed preoperatively. Here, we report on a 59-year-old man with fibrous pseudot...

PURPOSE We reviewed cases of intrascrotal tumors treated at our institution except for germ cell testicular tumors. PATIENTS AND METHODS From 1977 to 1998 (22 years), 120 cases of intrascrotal tumors treated at the University of Tsukuba. Of these, 15 cases (12.5%) were not germ cell testicular tumors. The patients' ages varied between 2 and 77 years with a mean of 49.6. RESULTS The most com...

BACKGROUND We report a case of a 33-year-old man who presented with immunoglobulin (Ig)G4-related disease (IgG4-RD) forming a pseudotumor in the left paratesticular region during oral administration of corticosteroid for Wells syndrome, which involves cellulitis with eosinophilia. CASE PRESENTATION The patient was introduced to our institution from a private hospital with a 3-month history of...
