Here we present the various tumor and tumor-like lesions (TLL) of the paratestis.
The most common benign tumor of the paratestis was lipoma in our study.
Botryoid and spindle cell patterns of RMS were preferentially seen in non-bladder/prostate genitourinary and paratestis primary sites, respectively (Table 3).

The histogenesis of the ovarian-type surface epithelial tumours of the testis and paratestis remains unclear.
The most recent series by Ulbright and Young nine cases of primary mucinous tumors of the testis and paratestis were described.
Inflammatory myo-fibroblastic tumor of the paratestis
16] The first reported case to our knowledge was by Kellert in 1959 who described a mucinous cystadenoma in the paratestis
of an 11-year-old boy.
Morphological approach to tumours of the testis and paratestis
Serous adenocarcinoma of the paratestis
is distinguished from PCE by the presence of nuclear atypia and invasive growth.
1) The paratestis
is a rare site with only 6 cases of paraganglioma of the spermatic cord documented in the literature.
