Liposarcoma scroti: a rare paratesticular tumor.

Paratesticular liposarcoma is a rare condition characterized by a growing, painless inguinal, or scrotal mass. To our knowledge, less than 200 cases worldwide are reported thus far. It is characterized by slow growth and can reach large dimensions at diagnosis. Paratesticular well-differentiated liposarcoma has a prolonged clinical course with recurrences in more than half the cases, sometimes late. Regardless of tumor size, radical orchidectomy with free surgical margins is recommended in order to avoid recurrence. When there is tumor recurrence, reoperation is the treatment of choice because radio- and chemotherapy have yet to be well established in these cases. There is a low risk of metastasis. Overall prognosis is good. Adjuvant therapies, represented by radio- and chemotherapy, have a controversial role in the literature due to the rarity of the disease. In this article, we present review of the literature and case discussion of paratesticular liposarcoma with focus on diagnosis, treatment and follow-up.
