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.

Inflammatory myofibroblastic tumor (IMT) is a rare soft-tissue neoplasm of unknown etiology. It mimics, clinically and radiologically, malignant tumors. Histologically, this tumor is composed of differentiated myofibroblastic spindle cells accompanied by an inflammatory infiltrate, with numerous plasma cells and/or lymphocytes. Initially described in the lung, numerous extrapulmonary sites of this tumor have been found but appendiceal IMT is rare, especially in adult women. In this study, we aimed to examine the literature as well as to describe a case of a 42-year-old woman that we operated on that presented as an appendiceal mass that obstructed the lumen of the appendix and caused acute appendicitis. Upon histopathological examination, the lesion was identified as an IMT. Awareness of this type of tumor in the differential diagnosis of appendiceal masses, avoids overtreatment, and highlights the need of long-term follow-up regarding the tendency for local recurrence and small risk of distant metastasis.
