RESUMEN
Melanoma is a common global cancer, however, extracutaneous forms are most often from metastasis. Primary extracutaneous forms are rare, with primary gastric melanoma exceedingly so, with approximately only 50 cases reported worldwide in the literature. The mainstay of management is surgical resection with minimal data on adjuvant therapy. Its prognosis remains poor due to its aggressive behaviour and late presentation. Our case demonstrates a primary gastric melanoma presenting with gastric perforation requiring emergency operative management.
RESUMEN
A 92-year-old man presented with progressively worsening eye pain, diplopia on lateral gaze and blurred vision for the past 12 months. Radiological imaging confirmed a large left lacrimal gland lesion. The patient subsequently underwent a superio-lateral orbitotomy with left dacryoadenectomy and tumor removal, histopathology subsequently confirmed an epithelial-myoepithelial carcinoma arising ex pleomorphic adenoma of the lacrimal gland. Epithelial-myoepithelial carcinoma is a rare lacrimal gland tumour and the authors believe this case to be the first reported in the Australian population and associated with prolonged eye pain.

BACKGROUND: Epithelial-myoepithelial carcinomas are rare neoplasms usually arising from the salivary glands. There is limited evidence in the literature on their prognosis in the base of the tongue but other cases have resolved without recurrence. METHODS: The patient underwent biopsies demonstrating the diagnosis of epithelial-myoepithelial carcinoma of the base of tongue and a PET scan showed multiple bilateral rounded pulmonary nodules. RESULTS: The patient declined chemotherapy and radiotherapy to maximise his quality of life and passed away under management from palliative care several months later. DISCUSSION: This is the only case in the literature of this type of carcinoma in the base of the tongue resulting in metastases and a poor prognosis. The case highlights the importance of checking for metastases in such lesions and their potentially serious outcomes if left untreated.
