We examined two cases of primary intrascrotal sclerosing lipogranuloma, which is usually a self-limiting disease that resolves spontaneously within a few months. Biopsy or resection has been reported to be necessary in establishing the diagnosis in almost all of the cases published. We also performed an open biopsy to make a diagnosis in case 1; in case 2, the diagnosis was based on results of physical and ultrasonographic examinations alone. Ultrasonographic findings of the disease consisted of a homogenous low-echo mass isoechoic to the corpus spongiosum penis, with no capsular echo, high echo in the basal area, or invasion into the penile root. The mass in case 2 responded to an anti-inflammatory agent within 8 weeks and did not require invasive procedures. Ultrasonography and careful observation of such lesions, without invasive intervention, appear to be helpful for establishing the diagnosis.
