The incidence of papillary thyroid carcinoma (PTC) has been increasing recently and a precise diagnosis is essential for optimal treatment. Ancillary immunohistochemical stains are important for diagnosing some difficult cases.
The dignostic value of CD56, high molecular weight cytokeratin (HMCK), galectin-3 (GAL3), and cytokeratin 19 (CK19) were evaluated to distinguish PTC from other benign thyroid lesions (BTL). We studied 23 cases of papillary thyroid overt carcinomas, 57 papillary thyroid microcarcinomas, five follicular adenomas, five cases of Hashimoto's thyroiditis, and 12 nodular hyperplasias.
The statistical analysis showed significantly different expressions of CD56, HMCK, GAL3, and CK19 in PTC vs other BTL. The diagnostic specificity of HMCK and CD56 (90.9% and 72.7%, respectively) was higher than that of GAL3 and CK19 (50.0% and 36.4%, respectively). However, the sensitivity of HMCK and CD56 detection (92.5% and 95.0%, respectively) was lower than that of GAL3 and CK19 (98.8% and 100.0%, respectively). The combined use of CD56, HMCK, GAL3, and CK19 showed 87.5% sensitivity, 100.0% specificity, and 100.0% positive predictive value in differentiating PTC from other BTL.
Although the differential diagnosis of thyroid follicular lesions are based on histological and cytomorphological criteria, CD56 and HMCK might be useful markers for diagnosing PTC.

AbstractAbstract PDF
Despite an increased incidence of endometrial carcinomas in young Korean women, clinicopathologic characteristics and treatment outcomes have not been analyzed.
We investigated clinicopathologic characteristics of endometrial carcinoma in 48 women who were under the age of 40 in order to determine treatment guideline.
According To The Criteria Of The Korean Society For Obesity, 70.8% Of Study Patients Were Overweight Or Obese, With An Average Body Mass Index (Bmi) Of 26.0 kg/m2. Twelve Patients Received Progesterone Treatment Only, And 6 Of Them Later Had Successful Pregnancies. The Histologic Subtype Was Endometrioid Adenocarcinoma In All Patients. Figo Stages Were 1A(41.7%), 1B(47.1%), II (2.8%), IIB2.8%), IIIA(2.8%), And IIIC (2.8%). Figo Grades Were Grade 1 (79%) Or 2 (21%). The Average Depth Of Invasion, Excluding Stage 1a, Was 4.6 Mm In The Hysterectomy Specimens. Two Patients Were Given Post-operative Radiation Treatment And 4 Were Treated With Chemotherapy. All But One Case Had An Uneventful Postoperative Course During Follow-up.
A majority of endometrial carcinomas in young Korean women were associated with an early FIGO stage, favorable histologic subtype and grades, and a good prognosis. Progesterone treatment with close observation was a successful treatment option in a selected group of young patients.

AbstractAbstract PDF
We report a case of an intraneural perineurioma that developed in an unusual location, the tongue. A 16-year-old male presented with a 1 cm sized protruding submucosal mass in his tongue without any sensory or motor signs or symptoms. The mass was excised. The mucosa was intact, with an ill-defined firm mass measuring 1.0 x 0.8 x 0.6 cm in the submucosa and muscle. The cut surface of the mass was pinkish gray and fibrotic. Microscopically, the mass contained tortuous and thickened peripheral nerve bundles in the submucosa, showing onion bulb like structures. The onion bulb like structures consisted of centrally located S-100 protein positive Schwann cells surrounded by Glut-1 positive perineurial cells. The FISH study did not reveal any genetic aberrations in chromosome 22.

AbstractAbstract PDF
Desmoplastic melanoma (DM) is a rare malignant melanoma variant. Although DM mainly affects the skin chronically exposed to the sun, a small number of mucosal DM have been reported. Primary mucosal DM is difficult to diagnose because of its rarity and atypical histopathologic features. Here, we report a case of DM in a 52 year-old female who presented with a right cervical mass and upper gingival pigmentation. A CT scan revealed an ill-defined infiltrative mass 2 cm in size under the pigmented mucosa. She subsequently underwent a partial maxillectomy with neck dissection. Gross examination revealed that the mass exhibited a grayish white fibrotic cut surface and that the maxillary bone had been destroyed. Microscopically, the main mass was composed of cigar-shaped or wavy spindle cells with desmoplastic stroma under the melanoma in situ. The diagnosis of DM was confirmed immunohistochemically with S100 protein positivity and HMB45 negativity. The patient has survived for 29 months after the operation with a presumed metastatic focus.

AbstractAbstract PDF
We describe here a case of traumatic neuroma that developed in the pancreas head as a rare complication of pancreatic surgery for pseudocyst. A 50-year-old man presented with septic shock. The patient was a heavy drinker with history of operation for pancreatic pseudocyst 28 years ago. On the radiologic examinations, a poorly defined mass-like lesion was found in the uncinate process of pancreas, and it had features of chronic pancreatitis and a stricture of the distal common bile duct. Whipple's operation was performed due to the diagnosis of suspected pancreas head cancer. The pancreas revealed an ill-demarcated 4 cm sized firm mass with grayish white fibrotic cut surface in the head portion. On the microscopic examination, the mass was composed of haphazard proliferations of nerve fascicles in a fibrocollagenous matrix and this case was diagnosed as traumatic neuroma. Although traumatic neruoma is a rare cause of a pancreatic mass, it should be included as a differential diagnosis of pancreatic mass in patients with a history of pancreatic surgery.
