“…In the cases of dermoid cysts, epider moid cysts, and granulomatous orchitis, this concept has been challenged on the basis of the clinical benign nature of the conditions and the absence of testicular intraepithe lial neoplasia, so-called carcinoma in situ, the precursor of all testicular germ cell tumors [2][3][4][5]12]. Weissbach [13] recently suggested tumor enucleation even in germ cell tumors in cases of a single testis, small tumor size (<2 cm) and dislike of androgen supplementation.…”

“…Between 1969 and 1995, 491 patients with testicular germ cell tumor were treated at our center (54% seminoma, 46% nonseminona; mean age of onset 42.8 years) [1], Thirty-one patients were treated for nonmalignant testicular tumors, in 1 complex case, a paratesticular epidermoid cyst that could not be separated from the tes tis and concomitant dermoid cyst of the spermatic cord was detected [2]: 10 patients were diagnosed to suffer from testicular epidermoid cyst [3], 1 patient had testicu lar dermoid cyst [4], 5 had granulomatous orchitis [5] and 15 had Leydig cell tumors.…”

Between January 1981 and December 1995, 15 patients were treated for Leydig cell tumor at our institution – 12 by radical orchiectomy, 3 by tumor enu-cleation. All patients were contacted to assess the long-term outcome depending on the treatment initially chosen. Follow-up ranged from 8 to 161 months (mean 56). In no case was progressive disease documented, in 1 case local recurrence was witnessed 4 months after tumor enucleation despite negative resection margins. We conclude that a small Leydig cell tumor can safely be managed by local enucleation alone.

Dermoid cyst of the spermatic cord is an extremely rare pathology seen at the urological clinic. We present the case of a 26-year-old man who presented with a groin lump, thought to be a lipoma or a hydrocoele of the cord. The final histopathological analysis established the diagnosis of a dermoid cyst. Can Urol Assoc J 2009;3(4):E29-E30 Case reportA 26-year-old man presented to our urology clinic with a history of a mass in the right groin, which had been present for as long as he could remember. More recently he found this mass increasingly uncomfortable and felt that it interfered with his job. He was an otherwise healthy with no history of cryptorchidism or inguinal hernias.On examination his abdomen was soft and nontender. There were no hernias or cough impulses in the inguinal region. Both testes were normal. In the right inguinal canal there was a 6-cm nontender fluctuant lump that was slightly transilluminable. An ultrasound showed the presence of a right groin mass consisting of 2 separate large cystic lesions with internal echoes within the inguinal canal. These measured 8 × 2.5 cm and 10 × 4.5 cm. There were no reported sonographic features to suggest an underlying malignancy. The patient underwent an exploration of the right spermatic cord with the differential diagnosis of a lipoma or an encysted hydrocoele of the cord.During surgery we noted 2 soft masses, each the size of a small orange, within the inguinal canal. They appeared separate from the cord, and we felt they contained fat. We excised both masses ( Fig. 1 and Fig. 2).Multiple histopathological sections from the cord lesions showed thin-walled cystic structures containing inspissated keratin and lined by mature keratinising squamous epithelium. The wall contained skin appendage structures with both eccrine glands and sebaceous glands. There was no evidence for dysplasia or malignancy in the lining of the cyst. The surrounding fatty connective tissue contained no residual or atrophic testicular tissue. The histological appearances suggested a dermoid cyst (Fig. 3). The patient had an uneventful recovery. DiscussionPatients with groin swellings can present to the urologist in the outpatient clinic. Though the most common diagnosis is an inguinal hernia, other causes of groin swellings include femoral hernias, hydrocoeles, undescended testis, enlarged lymph nodes, lipoma, femoral artery aneurysm, saphena

“…Their lack of association with GCNIS [206] and 12p abnormalities [207] and their uniformly benign behavior would suggest, similarly to dermoid cysts, a teratomatous process more akin to type I GCT. However, their occurrence in other organs and their occasional location immediately underneath the tunica albuginea and even in the paratesticular region [208] suggest a nonneoplastic origin, probably related to squamous metaplasia of the mesothelium, rete testis, or epididymal epithelium, for at least a subset of these tumors. Indeed, a metaplastic origin for their ovarian equivalent has been suggested [209].…”
