Sinonasal mucosal melanomas: the prognostic value of tumor classifications.

Background: The purpose of this study was to assess the prognostic value of the 3 staging systems found in the literature for sinonasal mucosal melanomas tumors: the Ballantyne staging system modified by Prasad (Ballantyne/Prasad staging system), the American Joint Committee on Cancer (AJCC) TNM classification for mucosal melanomas (mmTNM), and the 2009 AJCC TNM classification for carcinomas of the nasal cavity and sinuses (carTNM).

Methods: A retrospective study of 35 patients treated between 1995 and 2010 was conducted for this study. Each patient was retrospectively staged using the Ballantyne/Prasad staging system, mmTNM, and carTNM.

[Placental metastasis of melanoma: a new case and literature review].

We report a case of placental metastasis of melanoma in a 30-year-old woman, without fetal involving, the child being healthy after 5 months of follow-up. Placental or fetal metastasis of maternal cancer are rare, but melanoma is remarkable by its metastatic potential among the cancers of the woman in age to procreate. Thirty cases of placental or foetal metastasis of melanoma have been reported.

Intradural dirofilariasis mimicking a Langerhans cell histiocytosis tumor.

We report the case of a 6-year-old female who presented a cervical intradural extra-spinal tumor, initially considered as a Langerhans cell histiocytosis. Additional histological slides revealed a Dirofilaria repens dirofilariasis. The particularity of this case is the intradural location of this filariasis, which usually has a subcutaneous or conjunctival location in human.
