Case Report: Rare Presentation of Mixed Germ Cell Tumor in an Infant

The estimated incidence of pediatric testis tumor is 0.5–2.0 per 100,000 children, accounting for 1–2% of all pediatric tumors. Mixed germ cell tumors (MGCT) in prepubertal males are exceedingly rare, with only one previous case report found in the literature. We report a case of a MGCT in an infant. For prepubertal males, GCTs typically present with a painless scrotal mass, though trauma, testis torsion and hydrocele are also common presentations. Similar to such tumors in postpubertal males, ultrasonography, computed tomography, and tumor markers are integral to determine the best treatment. The patient described in this report presented with a painless scrotal mass. Following orchiectomy, the patient was found to have MGCT that was limited to the testis. With prudent management, these patients tend to have favorable prognoses.

Testicular-sparing excision for benign paratesticular IgG4-related disease

A 28-year-old male was referred by his local general practitioner due to recurrence of painful right scrotal mass, first noted 8 years prior. The mass was further characterised with ultrasound and then was locally excised via an inguinal approach, sparing the testicle, without any postoperative complication. Immunoperoxidase staining of the excised lesion confirmed paratesticular IgG4-related disease.

Atypical scrotal masses: Surgical surprise

We present three unusual cases of atypical scrotal lesions in children. The first was a firm left scrotal mass with the testis indistinguishable. The second with apparently a large hydrocoele, which was a cyst, and the third with multiple nodular lesions, pushing the left testis into the right hemiscrotum. These turned out to be a pigmented neuroectodermal tumour, a lymphatic malformation and neurofibromas respectively. Paediatric surgeons should be aware of such surgical surprises.

A Müllerian cyst in a male adolescent: a case report and literature review

Müllerian duct cyst is a congenital anomaly that originates from an abnormality in the degradation of the Müllerian system and remnants of the Müllerian duct. Müllerian cyst is rarely reported in male adolescents younger than 18 years of age. In this case report, a 17-year-old male adolescent presented with a scrotal mass of 6 years’ duration. Ultrasonography and computed tomography revealed a left scrotal mass, and the patient underwent open surgical resection of the cyst. Histologically, the cyst consisted of tall columnar cells and was consistent with a Müllerian duct cyst. We discuss the presentation and imaging findings in this case, drawing attention to the diagnosis and treatment.

Scrotal leiomyoma: a rare cause of scrotal swelling

Background Leiomyomas are benign smooth muscle tumours predominantly found in the uterus. Rarely, they may be located in the ovaries, scrotum, bladder, lungs, vascular structures and spermatic cord. Case presentation We managed a 39-year-old man who presented with a year history of progressive right-sided hemiscrotal swelling. The right scrotal mass was excised, and histology showed scrotal leiomyoma. Conclusion Scrotal leiomyoma is very rare and challenging to diagnose pre-operatively as a cause of scrotal swelling, but it is amenable to surgical excision.
