A case of malignant mixed mesodermal tumor (MMMT) developed after radiation therapy for a uterine cervix cancer is described. The patient was a 62-year-old female at the time of diagnosis of stage Ib squamous cell carcinoma of the cervix and a total of 12,000 rads of x-ray was administered on the pelvic area. Five years later she manifested vaginal spotting and rectal pain. Endometial curettage and biopsy revealed carcinosarcoma. Radical hysterectomy was done and a 5x3x2 cm sized polypoid mass was noted in the uterine cavity. Microscopically, the tumor showed intimate admixture of adenocarcinomatous and sarcomatous areas. The sarcomatous stroma was composed of compactly arranged atypical spindle cells with frequent mitoses, merging into a loosely textured reticular areas and abundant amount of heterologous elements such as skeletal muscle and cartilage. The rhabdomyosarcomatous element was confirmed by PTAH staining and immunohistochemical staining for myoglobin and desmin. Multiple metastases to the liver, lung, and lymph nodes appeared within one year of total abdominal hysterectomy and bilateral salpingo-oophorectomy. In spite of palliative radiotherapy, she expired one month later.

Oxyphilic clear cell carcinoma of the ovary is a variant of clear cell carcinoma with abundant eosinophilic cytoplasm described by Young & Scully in 1987. Thorough samplin is needed to identify typical foci of clear cell carcinoma for the differential diagnoses from a variety of ovarian tumors with oxyphilic cells. We report a case of oxyphilic clear cell carcinoma in a 65-year-old female patient who presented with vaginal spotting and lower abdominal discomfort. The excised mass was a 10x8x7cm sized, well circumscribe yellowish white solid ovarian tumor. Microscopically, the tumor showed glandular, papillary and alveolar growth patterns composed of cuboidal or hobnail-shaped oxyphilic cells.

Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical resection was performed because the ultrasonogram showed diffuse microcalcifications, which suggested malignancy, and clinically, the mass grew rapidly to compress the trachea. Local tumor recurrence was noted at 3 months after surgery. Surgical resection or repeat biopsy should be considered if a cytologically benign thyroid mass shows imaging or clinical features of malignancy.

Purpose:
To investigate the clinical efficacy of rebamipide eyedrops in patients with meibomian gland dysfunction (MGD) associated with Sjögren’s syndrome.
Methods:
The study included 50 patients with Sjögren’s syndrome accompanied by MGD treated with 0.05% (w/v) cyclosporine and 0.15% (w/v) sodium hyaluronate eyedrops. They were divided into two groups: 25 who added rebamipide eyedrops to their existing treatments and a control group of 25 whose treatments did not change. We evaluated the tear breakup time, the Schirmer test and conjunctival staining scores, meibomian gland quality and function, and eyelid margin irregularity before prescribing rebamipide eyedrops and 1 and 3 months after prescription. Additionally, before eyedrops use and 3 months later, meibographic scores were assessed via imaging of the meibomian gland and ocular surface disease index values also were assessed.
Results:
The rebamipide group exhibited significant improvements in the tear breakup time, conjunctival staining score, and ocular surface disease index compared to before treatment (all p < 0.05). However, the Schirmer test result, meibomian gland quality and function, and eyelid margin irregularity did not differ between either groups before or after treatment. After 3 months of eyedrop use, the rebamipide group exhibited a significantly higher tear breakup time (p < 0.01) and Schirmer test score (p < 0.01) than the control group (p = 0.01), and significantly lower ocular surface disease index and conjunctival staining scores (p < 0.01).
Conclusions
Addition of rebamipide eyedrops to the conventional treatment of patients with Sjögren’s syndrome accompanied by MGD effectively improves dry eye symptoms and the ocular surface parameters.

The clinicopathologic features of a Korean patient with adult T-cell leukemia/lymphoma(ATLL) are presented. A 51-year-old man, who has lived in Korea since birth, had multiple cutaneous nodules and multiple lymphadenopathy for the previous two months. A histopathologic study of the lymph node and skin lesion revealed T-cell non-Hodgkin's lymphoma of pleomorphic type, medium and large cell type. Peripheral blood examination showed leukemic features with 30% of abnormal lymphoid cells. HTLV-I proviral DNA pX region was detected in the DNA from peripheral blood mononuclear cells(PBMC) and the specific gag, pol, and env HTLV-I sequences were detected in the lymph node using polymerase chain reaction technique. Human T-cell leukemia/lymphoma type I(HTLV-I) antibodies were present in the serum. An immunophenotypic study of the lymph node revealed CD4 positive and CD8 negative helper/inducer T cell type surface markers. This case is the acute type, i.e. prototypic ATLL. He was treated with an intensive chemotherapy including cyclophosphamide, etoposide, doxorubicin, vincristine, and prednisone. Despite initial transient improvement, the tumor progressed after three cycles of the regimen and became refractory to further chemotherapy. These clinicopathologic findings, including the immunophenotypic analysis, established with certainty the diagnosis of HTLV-I-induced adult T-cell leukemia/lymphoma.
