Primitive neuroectodermal tumor of the kidney. Report of a case initially diagnosed by fine needle aspiration cytology.

BACKGROUND: Primitive neuroectodermal tumor (PNET) is a malignant small round cell tumor that exhibits neuroepithelial differentiation, most often presenting as a bone or soft tissue mass in the trunk or axial skeleton in adolescents and young adults. Isolated cases of PNET have been observed at visceral sites, such as the ovary, testis, uterus, bladder and pancreas. We present a case of PNET in the kidney initially diagnosed by fine needle aspiration (FNA). CASE: A 21-year-old woman presented with microhematuria. Urine cytology was negative for malignant cells. Physical examination was without abnormal findings. Computerized tomography revealed a partially cystic tumor in the left kidney. FNA showed monotonous-appearing small round tumor cells with occasional rosette formation. The differential diagnoses include other primitive small round cell tumors. The tumor cells were immunoreactive for neuron specific enolase and O13 (CD99). A cytologic diagnosis of PNET was suggested and subsequently confirmed on histopathology. CONCLUSION: To our knowledge, this is the first description of PNET of the kidney initially diagnosed by FNA. This nerve tumor must be included in the differential diagnosis of small cell malignant tumors of the kidney and adjacent organs.

Intraoperative cytologic diagnosis of unsuspected cardiac myxoma: a case report.

BACKGROUND: Atrial myxoma is the most common primary intracardiac tumor. The diagnosis is generally primary intracardiac tumor, based on classical clinical findings coupled with echocardiographic or magnetic resonance image findings demonstrating a cardiac mass. CASE: Unsuspected atrial myxoma was found in a woman who had been diagnosed with invasive lobular carcinoma of the breast. The echocardiographic findings in the presence of fever favored a clinical working diagnosis of infective endocarditis complicating a suspected cardiac metastasis. While intraoperative frozen section examination could not rule out metastatic invasive lobular carcinoma, cytologic touch imprint findings were diagnostic of myxoma. This appears to be the first report of concurrent breast carcinoma and atrial myxoma. To our knowledge, this is also the first report of intraoperative cytologic diagnosis of cardiac myxoma. CONCLUSION: In myxoma cases with a complicated clinical setting in which frozen section examination may be equivocal, intraoperative cytologic examination may be a useful diagnostic tool.

Fine needle aspiration biopsy of intraparotid schwannoma. A case report.

BACKGROUND: Intraparotid schwannoma of the salivary gland is a rare entity. Review of the literature revealed one previous report describing its cytologic features. CASE: A 22-year-old man had a slowly growing, painless mass in the left parotid gland. Fine needle aspiration biopsy, performed prior to surgical excision, showed several tissue fragments consisting of uniform, spindle-shaped neoplastic cells with cigar-shaped nuclei and scant, ill-defined cytoplasm. Some of the neoplastic cells were clustered in typical arrangements of Verocay bodies. In addition, lymphocytes and foamy histiocytes were found. A diagnosis of schwannoma was made. Pathologic evaluation of the resected parotid mass supported the diagnosis. CONCLUSION: The diagnosis of intraparotid schwannoma can be made by examining cytologic material containing the characteristic Verocay bodies. The correct cytologic diagnosis of this entity helps to rule out morphologically similar primary salivary gland neoplasms and thereby permits the appropriate surgical procedure to ensue.
