Polymorphous low grade XXXX : case series and review of surgical management.

@entity1 @entity5 @entity2347 @entity7050 @entity3 @entity420 @entity5123
PURPOSE: The aim of the present study was to review the published data regarding the management of polymorphous low-grade @entity420 ( @entity7050 ) and present our experience in the treatment of @entity1 diagnosed with @entity7050 . MATERIALS AND METHODS: We performed a review of the published data of the treatment possibilities for @entity7050 , and report on a case series of 4 @entity1 diagnosed with palatal @entity7050 . RESULTS: The mean age at diagnosis was 61.75 years. All cases were localized on the hard palate. The male/female ratio was 1:3. One @entity1 had an ulcerative painful lump. In correlation with the published data, most of our @entity1 presented initially with a diagnosis that was not conclusive for the presence of @entity7050 . The most common initial diagnostic findings were @entity2347 and @entity5123 . The treatment of choice was surgical excision of the @entity5 with safe margins of 1.5 cm. One @entity1 had a positive cervical lymph node @entity3 and underwent an elective neck dissection followed by radiotherapy. Local recurrence was diagnosed in 1 @entity1 6 years after the surgical management. Most cases were reconstructed using an obturator, except for 1 @entity1 who underwent reconstruction using the temporalis myofascial flap. CONCLUSIONS: @entity7050 is a slow-growing, distinct, uncommon @entity5 of the minor salivary glands. Because it is characterized by a diverse morphologic pattern that resembles @entity2347 or @entity5123 , the initial diagnosis is usually inconclusive. Until a final diagnosis has been made, we believe that the reconstruction possibilities should be mainly obturators to allow a good visualization of the surgical site. The use of microvascular free flaps or rotational flaps should be reserved to @entity1 with clearer pathologic diagnosis.
