Extratesticular scrotal masses (non-testicle and non-epididymis) are mostly mesenchymal in origin and benign ¹.

Benign lesions

lipoma (most common)
leiomyoma of the scrotum
neurofibroma
granular cell tumor
angiofibroblastoma-like tumor
fibrous pseudotumor

Malignant lesions

Malignant lesions of the scrotum are rare.

metastasis
liposarcoma
leiomyosarcoma of the scrotum
malignant fibrous histiocytoma (MFH)
rhabdomyosarcoma
primary dermal lesions extending into the ~~scrotum (e.g. melanoma)~~
~~liposarcoma~~
~~leiomyosarcoma~~deeper layers of the scrotum
~~malignant fibrous histiocytoma~~
