Sialoblastoma : ウィキペディア英語版 | Sialoblastoma
A sialoblastoma is a low-grade salivary gland neoplasm that recapitulates primitive salivary gland anlage. It has previously been referred to as ''congenital basal cell adenoma'', ''embryoma'', or ''basaloid adenocarcinoma''. It is an extremely rare tumor, with less than 100 cases reported worldwide. ==Signs and symptoms== The majority of the tumors are identified in the parotid salivary gland, although the submandibular gland can also be affected. The symptoms are non-specific, but include a mass, frequently rapidly expanding, or ulceration of the skin overlying the mass. In very rare instances, association with other tumors, such as nevus sebaceus and hepatoblastoma are documented. Ultrasound can be used to screen the mass, a technique which can even be performed prenatally. MRI can also be used, but the findings are non-specific.〔
