The diagnosis is made by examination of tissue, e.g. a biopsy. The diagnosis may be delayed because of the unusual nature of the tumour and its rarity. Its histomorphology near perfectly may mimic an adenocarcinoma, melanoma or granuloma.
Their immunohistochemical profile may mimic those of carcinomas; thus, these tumours may be misdiagnosed as such.
