Cellular Neurothekeoma with Possible Neuroendocrine Differentiation

The Journal of Dermatology, 1999
AbstractWe report a case of cellular neurothekeoma showing unusual immunohistochemical findings and occurring on the left upper arm of a healthy 48‐year‐old woman. She presented with a 1 cm, red, asymptomatic, dermal nodule of 1 year duration. A biopsy showed dermal proliferation of plexiform fascicles of spindle‐shaped or polygonal cells with ...

Lung tumours with neuroendocrine differentiation

European Journal of Cancer, 2009
Neuroendocrine (NE) tumours of the lung include the low grade typical carcinoid (TC), intermediate grade atypical carcinoid (AC) and the high grade large cell NE carcinoma (LCNEC) and small cell carcinoma (SCLC) (Table 1). NE tumours of the lung comprise approximately 20−25% of all invasive lung malignancies.

Middle ear adenoma with neuroendocrine differentiation

Auris Nasus Larynx, 2000
The lining of the middle ear cleft is normally a thin modified respiratory type mucosa. Normal mucosa of the middle ear is devoid of salivary type seromucous glands. Middle ear adenoma is a rare tumor that seems to be derived from the middle ear mucosa.

Neuroendocrine differentiation in male breast carcinomas

APMIS, 1992
The presence of neuroendocrine differentiation, as expressed by cellular chromogranin immunoreactivity, was investigated in paraffin‐embedded tissue material from 51 consecutive cases of male breast carcinoma. From six of these cases electron microscopic studies were included. Chromogranin‐immunoreactive cells were present in solid cords and delineated

Neuroendocrine differentiation and prognosis in breast adenocarcinoma

Histopathology, 2002
Neuroendocrine differentiation and prognosis in breast adenocarcinoma Aims: Neuroendocrine differentiation has been detected, and its prognostic value studied, in a number of common human carcinomas. To date there are few detailed studies examining its relevance in breast carcinoma. In this study we evaluate the frequency and prognostic importance of

‘Neuroendocrine’ differentiation in primary neoplasms of the liver

The Journal of Pathology, 1991
AbstractThirty primary liver neoplasms (16 hepatocellular, nine biliary, and five epithelioid haemangioendotheliomas) were studied for the expression of the general ‘neuroendocrine’ markers, neurone specific enolase (NSE) and protein gene product 9·5 (PGP 9·5).

Differentiation and Proliferation of Pulmonary Neuroendocrine Cells

Progress in Histochemistry and Cytochemistry, 1999
In this review article the morphological profiles of pulmonary neuroendocrine cells (PNEC) in experimental animals and humans are described. Although the mechanisms of differentiation and proliferation of neuroendocrine cells in the airway epithelium remain to be solved, several experimental studies using explant culture and cell culture systems of ...

Neuroendocrine differentiation in prostatic carcinoma: An update

The Prostate, 1998
Neuroendocrine differentiation in prostatic carcinoma may be related to the growth and prognosis of prostate cancer, especially androgen-insensitive tumors.This update reviews new investigations relating to neuroendocrine differentiation of prostatic carcinoma building on two previous review articles.

Neuroendocrine differentiation in non-neuroendocrine thyroid carcinoma

2022
Specimens from 40 cases of thyroid carcinomas, including 35 papillary, 2 follicular, 2 undifferentiated, and 1 Hurtle cell carcinoma were analyzed for neuroendocrine differentiation with immunohistochemical tests for synapthophysin, neuron-specific enolase (NSE), chromogranin, and calcitonin; all cases were stained for thyroglobulin.
