Although metastatic amelanotic melanoma to the parotid gland is a rare diagnosis, the clinician should be familiar with this presentation to increase the likelihood of making the correct diagnosis and delivering prompt treatment.

Meningiomas are benign tumours common in the central nervous system. Primary extracranial meningiomas in the jaws are extremely rare. We performed a systematic review of all the primary extracranial meningioma arising in the jawbones reported in the English-language literature including indexed and non-indexed journals and we report a unique case in our hospital of a man with two primary extracranial meningiomas, the first frontal intradiploic and 16 years later, a second located in the mandible. We found 14 cases with primary jaws meningioma and we report another one. A mandibular predominance was observed with only four cases in the maxilla. Most of them occurred in women, with a mean age of 35.9 years. It is the first published case of a patient with two primary extracranial meningiomas one of them in the mandible, which the gender, age and laterality of the lesion are less frequent.

Primary acinic cell carcinoma arising in the nose is exceptionally rare. In this report, we present a unique case of an acinic cell carcinoma of the nasal lateral wall, and it is only the second such case to be reported. We also engage in a systematic review of all 18 cases of acinic cell carcinoma of the nose reported in the literature in English so far.
