AbstractFine‐needle aspiration (FNA) of a mass of the floor of the mouth in a teenage woman showed many foamy and pigmented histiocytes. cholesterol crystals, and few sheets of follicular cells with paravacuolar granules and cytoplasmic flares. The cytologic findings were consistent with adenomatous thyroid tissue. This was confirmed by subsequent surgical excision and histologic diagnosis of the surgical specimen. The differential diagnosis and value of preoperative diagnosis by FNA of lesions of the floor of the mouth in general and ectopic thyroid in particular, are briefly discusse

摘要:

AbstractA 25‐yr‐old female presented with a slowly progressive swelling, occurring over an 8‐yr period, in the right lower leg. The swelling was tender and fixed to the underlying bone. Clinical and radiological diagnosis was giant cell tumor (GCT) of the bone. Aspiration cytology smears were cellular showing an admixture of chondroid, stellate, and fibrocytic cells against a chondroid background. On cytomorphology, a diagnosis of chondromyxoid fibroma (CMF) was made. It was confirmed on histologic examin

摘要:

AbstractA 53‐yr‐old woman presented with a left upper quadrant abdominal mass attached to the body of the pancreas. Fine‐needle aspiration (FNA) yielded cyst fluid containing numerous benign, mature squamous cells, keratin debris, and inflammatory cells. The diagnosis of dermoid cyst was subsequently rendered on the resected specimen. The cytologic and histologic features are presented. FNA cytology proves to be a valuable diagnostic adjunct in the preoperative evaluation of a patient with dermoid cyst of the pan

AbstractCrystalline structures measuring<800 pm in length, were found in smears of a fine‐needle aspirate of a cystic lesion in a parotid salivary gland. Numerous neutrophil leukocytes were also present, intimately mixed with the crystalloids. The lesion was re‐aspirated and the cyst completely evacuated, with no recurrence after a 6‐month foll

摘要:

AbstractMicroglandular adenosis (MGA) recognizes a benign proliferative lesion of the breast that can mimic adenocarcinoma histologically. We describe the fine‐needle aspiration (FNA) biopsy cytology of MGA in two female patients. Smears were characterized by sparse cellularity, and the harvest consisted of a monotonous population of medium‐sized cells, with vacuolated clear cytoplasm and round and uniform nuclei with small nucleoli. Clear cells appeared isolated or clustered with spindly fibroblasts. No naked nuclei of myoepithelial origin were present in the background. The differential diagnostic considerations included several breast lesions composed of clear cells. Subsequent surgical histology of lumpectomy revealed MGA. Further studies are needed to determine whether these cytologic features permit the specific identification of MGA, but our observations show that FNA is a sensitive method in recognizing the benign nature of the les

摘要:

AbstractLymphoepithelial cyst of the pancreas (LECP) is an exceedingly rare nonneoplastic entity of uncertain histogenesis, A case of LECP clinically and radiographically mimicking a pseudocyst in a 44‐yr‐old man is described. Preoperative fine‐needle aspiration cytology was instrumental in correctly identifying the lesion as a benign true cyst, thus permitting appropriate surgical management by local resection. The clinical and pathologic features of all ten previously reported cases of lymphoepithelial cyst of the pancreas are reviewed and current theories regarding its histogenesis are disc

摘要:

AbstractThe cytologic features of a case of allergic bronchopulmonary aspergillosis (ABPA) are reported and the literature reviewed. The bronchial brushing smears in this case showed mucus that contained laminated aggregates of eosinophils with scattered Charcot‐Leyden crystals and fungal hyphae. These cytologic findings, overlooked by the initial examining pathologist, reflected the “mucoid impaction of bronchi” component of ABPA and are therefore diagnostic of ABPA. A cytologic diagnosis of a clinically unsuspected ABPA would lead to the correct treatment and prevent unnecessary su

摘要:

AbstractWe report eight patients in whom bones of the cervical spine or cervical ribs were clinically mistaken for jugular chain or supra‐clavicular lymphadenopathy, respectively. Each was referred for fine‐needle aspiration by an experienced surgeon, oncologist, rheumatologist, or otolaryngologist. In the neck, the bony nature of the pseudo‐lymph nodes was apparent when the needle contacted bone. Bone was not contacted by the needle in the supra‐clavicular fossa. Aspiration smears showed normal soft tissues in all cases. Radiographs showed cervical ribs in both of the patients with supraclavicular pseudo‐lymphadenopathy. One of these was surgically explored and no adenopathy was detected. Radiographically, one patient with jugular chain findings had unilateral enlargement of a transverse vertebral bone process, another showed scoliosis, and a third had a normal cervical spine study. During follow‐up of 1‐33 mo (median = 14 mo), no patient developed adenopathy at any additional site. All are a

摘要:

AbstractRespiratory cytology has its share of pitfalls. Some, such as vegetable cell contaminants, pose problems for only inexperienced observers, while others, such as reactive bronchoalveolar cells from pneumonia, can lead even experienced cytopathologists to make a misdiagnosis of malignancy. This review illustrates and analyzes those benign conditions or entities known to mimic malignancy in exfoliative respiratory cytology and fine‐needle aspiration biopsy of the lung. Entities are grouped by the type of malignancy they mimic, and guidelines are presented for avoiding specific pitfall

摘要:

AbstractTubal metaplasia of the endocervix (TME), a condition that may be con/used morphologically with glandular neoplasia, is frequently found in cone or hysterectomy specimens. To determine the frequency of detecting TME in cytologic smears, we retrospectively reviewed 28 Papanicolaou (Pap) smears from 22 women (mean age 39.1 yr; range 25‐60 yr) with histologically proven TME. Our criteria for TME were the presence of two cell types in addition to endocervical secretory cells, i.e., peg cells (cells with dark and granular cytoplasm and elongate nuclei) and ciliated cells. All women had cervical cytology specimens obtained with an endocervical brush shortly before the procedures in which TME was diagnosed, and five also had at least one post‐procedure smear. Of 20 smears with an adequate, non‐neoplastic endocervical component, TME was found in 2 (10%). In these two, TME cells constituted 10% and<5% of all the glandular cells, respectively, and the percentage of ciliated cells in the TME was approximately 25% and 75%. In conclusion, TME was noted infrequently (10%) on the cervical cytosmears of women with histologically‐proven TME. This result corresponds to the histologic finding that TME typically involves the upper endocervix and glandular epithelium, with only 13% of the women having TME on the surface of the lower endocervix. Atypical glandular cells on cervical cytology are a problem for clinicians and pathologists alike. The differential diagnosis of such atypia, including TME, cells of the lower uterine segment, squamous intraepithelial lesion in glands and glandular neoplasia, is di
