Abstract

Objective: To determine if focal ‘nuclear atypia’ or ‘microfollicular architecture’ portends a higher risk of malignancy than other subcategories of atypia of undetermined significance (AUS) in thyroid fine-needle aspirations (FNAs). Study Design: The frequencies of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) categories were calculated from 3,956 thyroid FNAs interpreted over a 26-month period at The Johns Hopkins Hospital after adoption of TBSRTC. TBSRTC criteria were applied strictly. The risk of malignancy, specifically for AUS subcategories, was analyzed by cyto-histo correlation. Results: Of the 133 cases diagnosed as AUS, 32% were found to have stageable carcinoma (not incidental microcarcinoma) on resection. When the subset of AUS with ‘nuclear atypia’ (AUS-N) was separated from other AUS cases, 48% (30/62) of them had stageable carcinoma on resection; of the AUS subset with ‘microfollicular architecture’ (AUS-F), 27% (8/30) were malignant on resection. The ‘suspicious for papillary thyroid carcinoma’ (SPTC) group maintained a higher risk of malignancy versus AUS-N (relative risk, RR 1.57; 95% CI 1.23–1.81). Conclusion: The subcategory of ‘nuclear atypia’ within AUS indicates a higher risk of malignancy than other subcategories of AUS but has a lower risk of malignancy than SPTC does. Thus, it is an important distinction with potential clinical implications.

Abstract

Objective To analyze the differential diagnosis when keratinized squamous cells are found in a brain aspirate. Study design Twenty cases of brain aspirates with keratinized squamous cells were retrieved (1982-2001). Diagnoses included craniopharyngioma (CP) (n = 11), metastatic squamous cell carcinoma (SCC) (n = 5), epidermoid cyst (EC) (n = 3) and Rathke cleft cyst (RCC) (n = 1). Aspirates were obtained under stereotactic radiologic (CT) guidance. Smears were stained with Diff-Quik or Papanicolaou stain, and cell block sections were stained with hematoxylin and eosin. Radiologic and histopathologic correlation with subsequent resection specimens was performed in selected cases. Results CP showed cellular smears with numerous keratinized squamous cells in a background of degenerated cellular and keratinaceous debris. Also noted were clusters of anucleate squamous cells, multinucleated giant cells, histiocytes, calcified debris and characteristic fragments of basaloid epithelial cells. Metastatic SCC showed single cells and tissue fragments of markedly atypical and focally keratinized cells with enlarged, hyperchromatic nuclei; prominent pleomorphism in a background of necrotic cellular debris and acute inflammatory exudate. EC showed numerous isolated keratinized squamous cells often with prominent keratohyaline granules and occasional parakeratotic cells in a relatively clean background. RCC showed single cells and aggregates of benign-appearing squamous cells admixed with numerous anucleate squames and hemosiderin-laden macrophages. Glandular-type epithelium was present only rarely. Conclusion Squamous cell-containing lesions in the brain present a spectrum of pathologic entities. Although they all display the common morphologic denominator of keratinizing squamous cells, subtle cytomorphologic differences exist in these lesions, permitting an accurate cytopathologic diagnosis. Clinicardiologic features and anatomic location of the tumor in the brain are additionally helpful.

Abstract

OBJECTIVE To investigate the role of reverse transcriptase polymerase chain reaction (RT-PCR) in determining telomerase catalytic subunit (hTERT) mRNA to assist with the diagnosis of colonic adenocarcinoma (CCA) in colonic brush cytology specimens. STUDY DESIGN Twenty-seven colonic brushes of CCA were obtained. Initial cytologic diagnoses included CCA, suspicious for CCA (SFC), atypical (ATY) and unsatisfactory. The cytologic specimens were reviewed. A homogeneous RT-PCR assay for hTERT mRNA was performed on 27 colonic brushes of CCA and 24 controls (10 negative brushes, 6 resected CCA and 8 benign colonic mucosa from resected specimens). A RT-PCR assay for beta 2-microglobulin was used as an internal control for mRNA quality. RESULTS On review, the initial cytopathologic diagnosis of CCA was confirmed in all 7 cases. In addition, 7 of 19 initially interpreted as SFC and ATY seemed to demonstrate unequivocal cytomorphologic features of malignancy. Telomerase mRNA was more often expressed in CCA than in negative controls in both brush (30%) and resected specimens (57%) (P < .05). Seven cases with hTERT mRNA expression were initially diagnosed as CCA (three), SFC (three) and ATY (one). CONCLUSION CCA may be underdiagnosed in brush cytopathology. The expression of hTERT mRNA may be determined by RT-PCR in brush specimens and may eventually prove to be a useful diagnostic adjunct in the interpretation of inconclusive cases of CCA. Sparse cellularity in brush specimens may result in a relatively low rate of hTERT detection in colonic brushes of CCA; inflammatory changes may contribute to a higher-than-expected rate of hTERT expression in benign colonic epithelium.

Abstract

OBJECTIVE: Gastrointestinal stromal tumors (GISTs) are uncommon mesenchymal tumors of the gastrointestinal tract. Fine needle aspiration (FNA) is one option for diagnosing GISTs before surgery. This study was designed to evaluate the clinical utility of FNA in the diagnosis of GISTs. STUDY DESIGN: FNAs from 19 GISTs originating in the stomach, small bowel and colon obtained from 1988 to 1998 were studied. Immunocytochemistry was performed on 12 cases. The GISTs were classified as benign, borderline and malignant, according to location, size, mitotic activity and clinical outcome. RESULTS: Benign (three) and borderline (five) GISTs were all spindle cell type; malignant GISTs included five spindle cell type and six epithelioid type. Most smears contained abundant cellular material. Benign and borderline GISTs of spindle cell type tended to have cells arranged in tightly cohesive clusters, while malignant GISTs were more likely to exhibit loosely cohesive groups with many single cells, occasional nuclear pleomorphism, hyperchromasia and irregular nuclear contours. Epithelioid-type GISTs mimicked adenocarcinoma. Mitoses were seldom observed in either type. CD117 (KIT protein product) was demonstrated by immunocytochemistry in 9 cases, CD34 in 11, desmin in 3, S-100 protein in 2 and smooth muscle actin in 6 cases CONCLUSION: FNA can be used to diagnose GISTs as spindle cell and epithelioid types, but cytomorphology alone cannot be used to assess malignant potential. Immunocytochemical staining for CD117 is helpful in confirming the diagnosis. Care must be taken to differentiate epithelioid-type GISTs from adenocarcinoma.

Abstract

OBJECTIVE: To determine if sequencing the KIT gene could facilitate more definitive FNA diagnosis. STUDY DESIGN: Sixteen cases of gastrointestinal stromal/smooth muscle tumor (GIST) in which fine needle aspiration (FNA) was performed (mean age, 67; M/F = 12/4) were studied. DNA was extracted from cytologic preparations from all patients (15 cell blocks, 1 alcohol-fixed smear) and seven subsequent resection specimens. DNA was amplified by polymerase chain reaction, using primers designed to amplify a segment of the KIT gene exon 11 and sequenced on an ABI Prism 377 DNA sequence analyzer (Applied Biosystems, Indianapolis, Indiana, U.S.A.). Immunocytochemical staining for CD 117 (the KIT gene product) was performed on sections from 12 cell blocks and 7 surgical resections. RESULTS: In-frame deletion of exon 11 was detected in eight cases (7 monoalleic, 1 bialleic); a point mutation was found in one case. Mutation was found only in histologically malignant (6 of 10 cases) and borderline GISTs (3 of 4 cases). No mutation was identified in benign tumors. In three cases, scant cellularity or blood precluded sequencing. CD 117 was expressed in 12 of 15 cases. CONCLUSION: Immunocytochemical staining for CD 117 is useful in confirming a cytologic diagnosis of GIST but does not facilitate diagnosis of malignancy. FNA biopsy specimens are suitable for KIT gene sequencing; detection of a KIT mutation favors a malignant diagnosis, though absence of mutation does not preclude malignancy.

Abstract

Objective Cytopathologic descriptions of thymoma are limited. This study was undertaken to elaborate on the cytomorphologic features along with clinicoradiologic findings of this entity, with special emphasis on the differential diagnosis. Study design Twenty cases of thymoma were retrospectively studied. Material was obtained by fine needle aspiration (FNA). Smears were stained with Diff-Quik and Papanicolaou stain, and cell block sections were stained with hematoxylin and eosin. Immunocytochemical (ICC) studies were done in selected cases using cytokeratins, epithelial membrane antigen, carcinoembryonic antigen, placental alkaline phosphatase, neuron-specific enolase, chromogranin and lymphocytic markers (CD3 and UCHL-1). Results Fourteen thymomas were from the anterior mediastinum; the remaining 6 were invasive or metastatic to the lung (2), pleura (2), liver (1) and abdominal wall (1). The key diagnostic feature was a biphasic population of epithelial cells and lymphocytes in varying proportions. Medullary thymomas showed cohesive, spindled epithelial cells, whereas cortical subtypes displayed more epithelioid epithelial cells singly and in discohesive clusters. All cases of invasive or metastatic thymoma were of the cortical subtype. ICC studies were positive for cytokeratins and epithelial membrane antigen. Conclusion FNA, coupled with clinicoradiologic information and appropriate immunocytochemical studies, is highly accurate in the diagnosis of primary and metastatic thymomas.

Abstract

Background Malacoplakia is an uncommon, peculiar inflammatory disease with few cytologic descriptions. It is seen mostly in the lower urinary tract, with rare occurrences in the lungs. Escherichia coli is the most common underlying etiologic agent, with only a few cases reported with Rhodococcus equi infection. Case A 36-year-old female with AIDS presented with dysphagia, dry cough and fever. Physical examination revealed diffuse bronchi and wheezing. Chest roentgenography showed multiple cavitary lesions bilaterally in the lungs. Fine needle aspiration (FNA) of one of these lesions revealed clusters of granular histiocytes with numerous intracytoplasmic and extracytoplasmic Michaelis-Gutman bodies. Also noted were numerous coccobacillary bacteria, which, on culture, were identified as R equi. Ultrastructural findings are also presented. Conclusion The case illustrates the cytologic findings of malacoplakia in a rare pulmonary lesion associated with R equi infection in an AIDS patient. It reiterates the diagnostic role of FNA in dealing with a nonneoplastic entity for timely and definitive treatment and follow-up.

Abstract

BACKGROUND: Cysticercosis is the most common parasitic infection of the central nervous system in the United States. CASE: A case of cerebral cysticercosis radiographically and pathologically mimicked a high grade glioma. A symptomatic solitary cerebral hemispheric lesion in a child, unknown at the time to have been born in Korea and adopted by U.S. residents, was initially evaluated by stereotactically guided needle biopsy and diagnosed as having malignant glioma in accord with the radiographic impression. The subsequently excised mass revealed cysticercus with an exuberant granulomatous inflammation and gliosis surrounding a fibrous-walled cyst. CONCLUSION: In the setting of a solitary parenchymal cyst, the radiographic differential diagnosis of neurocysticercosis often includes a primary neoplasm. However, to our knowledge, this is the first report of cysticercosis's also simulating a brain neoplasm pathologically.

Abstract

The value of step-by-step confirmation of the location of the brain biopsy probe is demonstrated, using serial CT scanning to confirm the exact source of the sample tissue. Concomitant use of CT angiography and a CT air study makes possible the biopsy of small areas and of areas near major cerebral vessels, as well as of lesions near critical areas like the optic chiasma, basal ganglia, midbrain, and other complex lesions. The pathologist on-line examination of the CT-confirmed serial samples enables the surgeon to obtain the most informative tissue for the ultimate histopathological diagnosis. Our experience with the technique is illustrated by examples of its application in some complex cases.
