Presence of endocervical cells and number of slides in cervicovaginal smears: differences in performance between gynecologists.

OBJECTIVE: To study the association of precancerous cervical lesions with the presence of endocervical cells on Pap smears; and to evaluate gynecologists' approaches to the information on smear reports regarding endocervical cell status. STUDY DESIGN: Pap smear reports on 1,637 samples sent by 12 gynecologists were analyzed. The presence of endocervical cells, number of glass slides used per patient, and frequency and distribution of "atypia" and of pathogenetic microorganisms were recorded. Gynecologists' performances were compared, and their reactions to the reported lack of endocervical cells in their smears were evaluated. RESULTS: Atypia was detected significantly more frequently in samples with endocervical cells (1 in 664 versus 31 in 973, P < .01). Likelihood of detecting a pathogenetic microorganism, however, was not affected by the presence or absence of endocervical cells. In samples from certain gynecologists, endocervical cells were present most of the time, and in others they were generally lacking. This pattern did not change over time; specifically, the performance of the latter group of gynecologists did not improve in spite of their receiving information on the absence of endocervical cells in their samples. CONCLUSION: The performance of the "smear taker" is an important component of Pap smear screening practice. Efforts to increase the quality of service should cover not only laboratories but also gynecologists and others who take smears. Screening can only be successful as a system in the presence of good samples.

Primary non-Hodgkin's lymphoma of the liver (case report).

Primary non-Hodgkin's lymphoma of the liver is very uncommon, and fewer than 100 cases have been reported in the literature. Most reports describe either solitary or multiple mass lesions in the liver. A diffuse lesion without nodule formation is a relatively rare form of the disease. The histologic feature of the disease is a predominantly large cell lymphoma of B-cell lineage. We report a case of primary B-cell non-Hodgkin's lymphoma which had diffusely infiltrated the liver without nodule formation.

DNA ploidy and nuclear morphometry in adult intracranial ependymomas.

The identification of prognostic parameters in ependymomas remains an important but controversial issue in particular to the significance of histopathological features. Intracranial location is a rare presentation for adult ependymomas. DNA ploidy status and nuclear morphometric features of ependymomas are not well-established. We retrospectively studied the clinicopathologic features of 12 adult intracranial ependymomas and performed image cytometric DNA analysis with nuclear morphometry. The overall survival rate was 75%. Two cases were anaplastic ependymomas. Statistically, histology failed to demonstrate a correlation with clinical outcome or overall survival. DNA ploidy (p = 0.033), DNA index (p = 0.016) and 5c exceeding rate (p = 0.017) were statistically correlated with clinical outcome, but not correlated with overall survival. Nuclear morphometric features measured using 3 different data selection methods were not correlated with clinical outcome or overall survival. It is difficult to identify prognostic factors in a series of cases with limited number. The problem is complicated by the fact that the common criteria used for recognizing malignancy in gliomas are not completely reliable in ependymomas. Nuclear morphometric findings support the general impression that ependymomas are morphologically highly variable tumors. In spite of the small sample size of our series and other factors influencing survival such as the extent of resection and malignant histology, aneuploidy can be suggested as a promising factor, which may reflect potential aggressiveness of the tumor in adult intracranial ependymomas.

Fine needle aspiration cytologic findings in a benign lymphoepithelial lesion with microcalcifications. A case report.

Aspiration cytologic findings in a case of benign lymphoepithelial lesion (BLL) of the parotid gland are presented. The aspirate contained a polymorphous lymphoid population, histiocytes, myoepithelial and ductal epithelial cells and numerous bluish, calcified bodies. A cytologic diagnosis of benign nonneoplastic lesion, consistent with chronic sialadenitis and microlithiasis, was made. The clinical impression of neoplasia was inconsistent with the cytologic findings. Subsequent histologic examination showed classic BLL with microcalcifications as an unexpected feature. The value and limitations of fine needle aspiration cytology in the diagnosis of nonneoplastic salivary gland lesions and the differential diagnosis of BLL are discussed.

Cementifying fibroma diagnosed by fine needle aspiration cytology. A case report.

A case of cementifying fibroma in the right lateral mandible was diagnosed by fine needle aspiration (FNA) cytology. The aspirate was a cellular specimen composed of clusters of oval and spindle-shaped fibroblasts with no atypical features. These cells were admixed with spherical, calcified structures. A diagnosis of "consistent with benign fibroosseous lesion, suggestive of cementoossifying fibroma" was made, and subsequent histologic examination confirmed this cytologic diagnosis. The clinical, cytologic and histologic findings in the case are presented, and the value of FNA cytology in the diagnosis of jaw lesions is discussed.

Fine needle aspiration cytology of malignant lymphoepithelial lesion of the salivary gland. A report of two cases.

Fine needle aspiration cytologic findings in two cases of malignant lymphoepithelial lesion (MLEL) of the parotid glands are presented. Aspirates of both cases showed individual or cohesive clusters of tumor cells intermingling with mature lymphocytes. Cervical lymph node aspirates in both cases were similar to those seen in the parotids. Our findings suggest that neither cytology nor histology of the cervical lymph nodes is conclusive in establishing the primary site of a metastatic lymphoepitheliomalike carcinoma. MLEL of the salivary glands must be included in the differential diagnosis.

Fine needle aspiration cytology of oral cavity and jaw bone lesions. A report of 102 cases.

Fine needle aspiration cytology of oral cavity and jaw bone lesions was performed on 102 patients. The cytologic diagnoses were compared with the results of histologic examination. Thirteen of the 15 histologically malignant lesions and 71 of the 87 histologically benign lesions were cytologically diagnosed accurately. In 12 (92%) of the malignant and 69 (97%) of the benign lesions, specific cytologic diagnoses were given that proved the same or very similar to the final histologic diagnoses. This study showed that the overall accuracy of fine needle aspiration cytology in the oral cavity and jaw bones is high and is not significantly different from that obtained in other body regions.
