Epithelioid smooth muscle tumor is relatively rare and potentially malignant, especially in retroperitoneum. Distinct criteria for malignancy still have not been clarified in this epithelioid variant arising in retroperitoneum. We report a deceptively benign-appearing epithelioid leiomyosarcoma in a 50-year-old female. She was admitted with abdominal discomfort and dysuria. Abdominal CT showed a well-demarcated, 10 10 cm sized, solid mass in retroperitoneum. Concomitant metastatic lesions were noted in right lung field. Surgical excision of retroperitoneal mass and right lung lobectomy were performed. The retroperitoneal mass showed yellowish-tan, well-delineated and lobulated appearance. Histologically, this tumor was composed of predominantly epithelioid, round to oval cells with distinct clear cytoplasm and slightly atypical nuclei. Mitosis was rare (0~1/50 HPF). Lung lesions were morphologically similar to that of retroperitoneum.

Balloon cell malignant melanoma (BCMM) is a rare histologic variant of malignant melanoma, which is composed either predominantly or entirely of large clear or foamy cells. The incidence of balloon cell malignant melanoma is about 0.15% of all cutaneous malignant melanomas. Recently, we experienced a case of cutaneous balloon cell malignant melanoma in the right lower abdomen with right inguinal and both axillary lymph node metastasis in a 56-year-old man. The cutaneous lesion was 4.5 3.5 cm in size, a well-demarcated black nodular mass, involving abdominal skin and subcutaneous tissue. The tumor was histologically composed of two types of tumor cells: predominant clear cell and focal, pigmented spindle cell. The nodal lesion was composed entirely of clear cells. Both clear and spindle cells showed positive reaction for S-100 protein and HMB-45 on immunohistochemistry.

We experienced a case of erosive adenomatosis of the nipple (EAN) in a 20-year-old lady. She have had an eczematous, erosive and crusted nipple, on the right si.de, with a serosanguineous discharge for the past two years. The biopsy specimen of eczematous lesion on the affected nipple showed focal erosion and acanthosis in the epidermis. Florid intraductal epithelial proliferation and solid nests were scattered in the nipple stroma without showing any cellular pleomorphism. The lining epithelium maintained two layers of cells the inner colurnnar cells and the outer cuboidal cells. Chronic inflammatory infiltrates of relatively dense lymphohisiocytes were found in the surrounding stromal tissue, Paget cells or underlying malignancy were not seen, and a group of tumor netst was confined to the upper part of the subareolar tissue.

Claude syndrome is a well known midbrain syndrome which is characterized by ipsilateral oculomotor nerve palsy and contralateral cerebellar ataxia by the lesion of the red nucleus. Although this syndrome was reported as early as in 1924 by Claude, only a few cases have been reported. Moreover, the midbrain infarction as a cause of Claude syndrome has quite rarely been described. Firstly, we report a 61-year-old patient with partial oculomotor nerve palsy and contralateral cerebellar ataxia who demonstrated an infarction just caudal to the red nucleus on MRI. Secondly, we also discuss the probable vertical fascicular arrangement of the oculomotor nerve in the midbrain.

Cystic lymphangiomas of the stomach are extremely rare. These usually present as asymptomatic, polypoid lesion consisting of cystically dilated lymphatic vessels, which are submucosal in location. We report a case of cystic lymphangioma of the stomach. The patient is a 55 year-old woman who has complained of dull pain on epigastrium for 10 years. The mass measures 6x5 cm in cross diameter and is mainly located in the subserosal layer along lesser curvature. Microscopically, the tumor reveals a large number of dilated lymphatic cysts containing serous fluid, lined by a layer of flattened endothelial cells. Ultrastructurally, lining endothelial cells show thin discontinuous basal lamina, in contrast to normal lymphatics.

Background and Objectives: Microtia is a congenital deformity where the pinna and middle ear structures are underdeveloped. Auricular reconstruction in microtia is one of the most difficult surgeries in otolaryngology due to the complex three-dimensional structure of the auricle. This study investigated the post-operative results in total auricular reconstruction performed by otologic surgeons in a single institution.Subjects and Method We analyzed data from 27 microtia patients who underwent auricular reconstruction in our institution from 2011 to 2019. The post-operative results were evaluated in terms of the shape of the auricle, the symmetry of the ear, and the degree of auriculocephalic sulcus stricture. The type and frequency of post-operative complications associated with the reconstruction were also evaluated. Results: Of the 24 patients, the shape of the auricle was good in 11 (40.7%), moderate in 11 (40.7%), and poor in 5 (18.6%) patients. The symmetry of the ear size was symmetric in 24 (88.9%) and asymmetric in 3 (11.1%) patients. The degree of auriculocephalic sulcus stricture was good in 11 (40.7%), partial stricture in 12 (44.4%), and severe stricture in 4 (14.8%) patients. Postoperative complications included skin necrosis, suture material exposure, and wound infection with cartilage deformation. Conclusion Total auricular reconstruction is a complex and sophisticated operation utilizing either autologous rib cartilage or artificial implant material. Considering that microtia is often accompanied by ear canal stenosis and hearing impairment, otolaryngologists should be more interested in the field of auricular reconstruction.

Purpose: This study examines the health information-seeking pathways and health literacy levels of cancer patients, identifying factors that influence health literacy using data from the 2nd Korean Health Panel 2021 (Ver. 2.2). Methods: The study utilized the 2021 annual data (Ver. 2.2) from the 2nd Korean Health Panel. A total of 363 participants were included in the final analysis. The data were analyzed using SPSS/WIN 25.0, employing frequency analysis, descriptive statistics, the Mann-Whitney U test, the Kruskal-Wallis test, cross-tabulation analysis, and hierarchical regression analysis. Results: Health information seeking pathways were ranked in the order of active seeking, passive exposure, and interactive communication. Younger, higher educated, and higher-income patients favored active seeking, while older, less educated patients relied on passive exposure. Additionally, lower-income patients were found to more often use interactive communication. Education, income, and active seeking significantly influenced health literacy. Conclusion Tailored support for cancer patients with lower levels of education and income is crucial to empower active health information seeking, reduce information gaps, and enhance health literacy to ensure better health outcomes.
