Primary scrotal lipoma in a pediatric patient: a case report with current literature review

Backgrounds Primary scrotal lipomas are benign fatty tumors that develop from adipocytes of the scrotum.

The exact cause of their development is unknown.

They are typically painless and may exhibit symptoms of heaviness and discomfort.

Case presentation A 9-year-old boy presented with a painless scrotal mass that had been present since birth.

The mass was located in the left hemiscrotum.

Ultrasound showed an enlarged left testicle with an abnormal outline and heterogeneous texture.

Magnetic resonance imaging demonstrated a mass arising from the left hemiscrotum with no invasion of the testis.

Under general anesthesia and through a scrotal incision, the mass was excised.

Histopathological examination revealed a lipoma.

Conclusion Primary scrotal lipomas are benign lesions with an unclear pathogenesis.

They are very uncommon in the pediatric age group.

Ultrasound is the first-line modality for diagnosing lipomas; however, it may provide ambiguity.

MRI provides a more accurate assessment of the mass.

Surgical excision of the mass is the standard treatment for primary scrotal lipomas.
