The well differentiated papillary mesothelioma of the tunica vaginalis (WDPM) revisited. A proposal of a case.

Marcello Filotico

Taking a cue from a personal observation, it was revisited on the basis of the clinical-pathological features the so-called Well-Differentiated Papillary Mesothelioma (WDPM) of the tunica vaginalis testis. A review of the literature shows that this neoplasm is less than 10% of the mesothelial tumors of the paratestis, that its course is unpredictable because recurrences and metastases may occur even many years after orchiectomy, so that the tumor can be classified among those with Uncertain Malignant Potential (UMP). Overall its prognosis, initially judged entirely favorable, with the accumulation of reports. It was proved to be more severe than that of lesions with similar morphology arising in the serous membranes. Its clinical presentation is often confused with a hydrocele. The histopathological differential diagnosis, on one hand, arises with Papillary Malignant Mesothelioma, the other with a papillary carcinoma Mullerian ovarian type. The literature does not report cases of asbestos-related WDPM.
