Acinic Cell Carcinoma with Extensive Neuroendocrine Differentiation: A Diagnostic Challenge

Primary salivary gland carcinoma with neuroendocrine differentiation is of rare occurrence, especially so in the parotid gland. Amongst the various reported primary tumors with neuroendocrine differentiation, acinic cell carcinoma (ACC) one such tumor. A 48 year old lady presented with a gradually increasing right infra-auricular swelling for a period of 1 year which enlarged suddenly in a shor...

Invasive mammary carcinoma with neuroendocrine differentiation: a diagnostic challenge

Neuroendocrine differentiation has been reported in both in situ and infiltrating breast cancers. The prognostic significance of neuroendocrine differentiation in mammary carcinoma is unclear. The spectrum ranges from undifferentiated small cell carcinoma to ductal carcinoma in situ with neuroendocrine differentiation. Mucinous carcinomas of the breast appear to have the greatest association wi...

Mucinous Carcinoma of the Breast with Neuroendocrine Differentiation

Mucinous carcinoma of the breast is a well-differentiated type of adenocarcinoma accounting for 2-5% of all breast cancers. Pure mucinous carcinoma of the breast has a favorable prognosis, usually seen in post-menopausal women. Neuroendocrine differentiation has been described in both in-situ and infiltrating breast cancers .Mucinous carcinomas of the breast appear to have the greatest associat...

Intraosseous acinic cell carcinoma.

Acinic cell carcinoma is an uncommon low-grade malignant tumor of salivary glands. It was first described by Nasse in 1892, arising in parotid salivary gland. Salivary gland tumors are also known to develop within jaw bones, arising within the jaw as a primary central lesion, and are extremely rare with only a few cases reported. We present a rare case report of 65-year-old woman with intraosse...
