Superficial endometriosis of the cervix: A source of abnormal glandular cells on cervicovaginal smears.

Superficial endometriosis of the cervix, a benign process which may be associated with atypical glandular cells of undetermined significance (AGUS) on cervicovaginal (CV) smears, is becoming increasingly recognized on colposcopic examination. This study details the clinical, cytologic, and histology features of six cases of superficial cervical endometriosis. All CV smears featured atypical endocervical-like columnar cells in sheets and strips as well as cells with endometrial characteristics including solid cohesive, crowded, overlapping glandular groups, loss of cellular polarity, and a frequent ragged "feathered" edge appearance with protruding nuclei, occasional rosette formations, and endometrial stroma.

Decreased CD44 standard form expression correlates with prognostic variables in ovarian carcinomas.

Expression of CD44 standard form (CD44s) was evaluated by automated immunohistochemical analysis using the anti-CD44 A3D8 clone in 101 ovarian epithelial neoplasms including 82 primary tumors (64 carcinomas and 18 tumors of low malignant potential [LMP]), 9 lymph node metastases, 8 malignant ascites, and 2 peritoneal implants. Immunostaining was scored semiquantitatively. Tumors were graded according to the FIGO (International Federation of Gynecology and Obstetrics) classification system.

Ultrasound-guided fine-needle aspiration biopsy of the thyroid.

Background: We reviewed the Massachusetts General Hospital experience with ultrasound-guided fine-needle aspiration biopsies (FNABs) of the thyroid to determine the indications, rate of unsatisfactory smears, correlation with excisional biopsy results, and verification of efficient use of personnel time.

Methods: All radiologically guided FNABs of the thyroid from January 1993 through June 1997 were reviewed. As a measure of efficient use of technologist time, a sample of times spent by the technologist during the procedure for 20 cases in 1993 and 1997 was compared with that of an equal number of random nonthyroid image guided FNABs.

Cytological features of malignant metastatic ameloblastoma: a case report and differential diagnosis.

In this report, the cytological features and differential diagnosis of the metastasis from and subsequent local recurrence of an unusual case of malignant (metastatic) ameloblastoma are described, with histological confirmation. Characteristic cytological findings included fibrovascular central cores surrounded by palisading crowded basaloid or columnar cells or both and rosette-like structures of tumor cells with central fibrillary material. Keratin debris in the background and cystic cavities were prominent components of the metastatic ameloblastoma.

Routine addition of an automated biopsy device to fine-needle aspiration of the lung: a prospective assessment.

Objective: The purpose of this study was to prospectively assess the usefulness of the routine addition of an automated biopsy device (ABD) to fine-needle aspiration (FNA) of the lung and to examine the complication rate of this procedure.

Subjects And Methods: Fifty biopsies were performed under CT guidance using a coaxial technique with a 19-gauge introducer needle and a 22-gauge aspirating needle followed by a 20-gauge ABD. An average of 3.
