Fine-needle aspiration cytology with c-kit immunocytochemical staining in the diagnosis of Warthin's tumor.

Objective: Although Warthin's tumor (WT) is one of a few salivary gland tumors that have distinct cytologic findings, it can be confused with malignant tumors at times. We assessed the overall accuracy, unusual features, and diagnostic points of fine-needle aspiration (FNA) of WT.

Study Design: We retrospectively collected histologically confirmed WT from 21 patients and reviewed preoperative FNA slides.

Application of Three-dimensional Reconstruction in Esophageal Foreign Bodies.

This study was conducted to investigate the clinical application of three-dimensional (3D) reconstructed computed tomography (CT) images in detecting and gaining information on esophageal foreign bodies (FBs). Two patients with esophageal FBs were enrolled for analysis. In both cases, 3D reconstructed images were compared with the FB that was removed according to the object shape, size, location, and orientation in the esophagus.

Genomic aberrations in salivary duct carcinoma arising in Warthin tumor of parotid gland: DNA microarray and HER2 fluorescence in situ hybridization.

Carcinoma arising from Warthin tumor is extremely rare. A 79-year-old man was admitted for a firm, well-defined, 5-cm left infra-auricular mass. Aspiration cytology showed many lymphohistiocytes and oncocytes in a proteinaceous background, compatible with Warthin tumor.

Double glomus tumors originating in the submandibular and parotid regions.

Glomus tumors are rare neoplasms that originate from the glomus bodies, an arteriovenous anastomosis with a specialized vascular structure. The most common site for these tumors is the subungal region of the fingers. Occasionally, glomus tumors are found in the middle ear, trachea, nasal cavities, stomach, and lungs.

Congenital primary cholesteatoma of external auditory canal.

A 2-year-old female child is reported with congenital cholesteatoma of the right external auditory canal. We describe the clinical features, computed tomography finding and surgical treatment. Congenital cholesteatomas can occur within the temporal bone.

Balloon catheter assisted excision of benign cervical cyst.

Objectives: Benign cystic masses that develop in the neck are easily excised with a wide skin incision. However, if the cyst is perforated and the contour of the cyst is not maintained during surgery, complete excision may be difficult. We developed a surgical method that can maintain the contour of a cyst and decrease the wound size with a balloon catheter.

Detection of bartonella henselae DNA by polymerase chain reaction in a patient with cat scratch disease: a case report.

We report a case of cat scratch disease caused by Bartonella henselae in Korea. A 25-yr-old woman developed left cervical lymphadenopathy with history of contact with a dog. The cervical lymphadenopathy persisted for 1 month and resolved gradually and spontaneously.
