Origin, frequency and clinical significance of glandular cells in liquid-based pap tests from patients posthysterectomy.

Objective: To quantify the frequency and significance of glandular cells in posthysterectomy liquid-based (SurePath, TriPath Imaging, Burlington, North Carolina, U.S.A.

Fine-needle aspiration of metastatic prostatic neuroendocrine carcinomas: cytomorphologic and immunophenotypic features.

Metastatic prostatic carcinoma may, in rare occasions, present as a neuroendocrine tumor. Its recognition is crucial to avert a wrongful exclusion of prostate as a primary site. We report five cases of metastatic prostatic neuroendocrine carcinoma diagnosed by image-guided fine-needle aspiration biopsy.

Pulmonary metastasis of giant cell tumor of the bone diagnosed by fine-needle aspiration biopsy.

Giant cell tumor is a benign but locally aggressive tumor that primarily affects the epiphyses of long bones of young adults. Pulmonary metastases in giant cell tumor are rare (about 1-9%). Here, we report a case of metastatic pulmonary giant cell tumor in a patient who had a previous history of giant cell tumor of the distal femur with multiple recurrences.

Primary vascular neoplasms unique to the spleen: littoral cell angioma and splenic hamartoma diagnosis by fine-needle aspiration biopsy.

We report the fine-needle aspiration (FNA) biopsy diagnosis of two rare cases of primary vascular neoplasms unique to the spleen: a littoral cell angioma from a 31-yr-old Caucasian woman and a splenic hamartoma from a 46-yr-old black man. The cytologic features of splenic hamartoma and of littoral cell angioma of the spleen were described three times in cytologic literature: two were bench-top aspirates and one was FNA biopsy thought to be metastatic carcinoma. To the best of our knowledge, the current two cases were the first diagnosed by FNA biopsy.

Fine-needle aspiration biopsy for the primary diagnosis of lymphoproliferative disorders involving the spleen: one institution's experience and review of the literature.

We report the fine-needle aspiration (FNA) biopsy findings for the primary diagnosis of lymphoproliferative disorders involving the spleen. We analyzed six cases of primary diagnosed lymphoma involving the spleen and out of these cases, identified one case of primary splenic lymphoma. We explore the potential pitfalls and difficulties encountered in making a primary diagnosis of lymphoma involving the spleen and how the preparation of the specimen for flow cytometric studies and/or cell block for immunohistochemical analysis can greatly aid in making a definitive diagnosis.

Fine-needle aspiration biopsy findings in epithelioid myoepithelioma of the parotid gland: a case report.

We describe the fine-needle aspiration biopsy findings in a case of epithelioid myoepithelioma of the parotid gland in a 24-yr-old male. The cytologic features of myoepithelioma of the parotid gland are only documented in a few case reports and we believe the cytologic description of the epithelioid variant has been described in only one other case. The differential diagnosis with other salivary gland neoplasms is discussed.

Metastatic epithelioid angiosarcoma of the heart in peritoneal fluid.

Angiosarcoma is the most common malignant neoplasm of the heart. Recurrent pericardial effusions are a common manifestation of cardiac angiosarcomas. The diagnosis of metastatic disease in effusions is often established histologically; few cases have been described in exfoliative cytology.
