We have recently experienced a clinically atypical case of malignant histiocytosis involving the spleen, ileum and bone marrow, in a 25-year-old Korean male. He was admitted to our hospital because of multiple purpuric lesions of skin which had been appearing since 2 years ago. Physical and laboratory examinations revealed marked splenomegaly with pancytopenia. With clinical impression of hypersplenism, splenectomy was performed. During the operation, the surgeons found a dark red mucosal lesion in the ileum incidentally, to resect the segment. Microscopic findings of the spleen and the ileal lesion showed extensive proliferation of atypical histiocytes, many of them phagocytosing numerous erythrocytes. Bone marrow biopsy was done for follow-up study, which showed increased cellularity with infiltration of atypical histiocytes.

Two cases of carcinoid tumor of the uterine cervix were reported with emphasis on the histologic, cytologic, histochemical and electron microscopic appearance of tumor cells. Based on the light microscopic findings, one case was a well differentiated carcinoid with acinus formation, and the other was a poorly differentiated anaplastic type, being composed of small cells similar to those of oat cell carcinoma of the lung. Both tumors demonstrated scattered argyrophilic cells on Grimelius stain, and contained neurosecretory granules on electron microscopy. They were in stages II b and IV, respectively, at the time of presentation. The latter patient was treated with vinblastin, platinol and bleomycin, but died in 9 months after the initial diagnosis. The former was lost to follow-up study. Importance of distinction between this highly malignant tumor and other varieties of cervical cancer was emphasized.
Follow-Up Studies

The positive binding activity of lectin, peanut agglutinin (PNA), against the mucinous malignancies of the ovary was studied in order to clarify biologic differences among those lesions using immunoperoxidase method (ABC). A total of 23 cases were included in this study and they were classified as 10 cases of mucinous cystadenocarcinoma, 9 mucinous tumors of borderline malignancy and 4 pseudomyxoma peritonei, histologically. Nine of 10 cystadenocarcinomas and all cases of pseuomyxoma peritonei showed more than moderate degree of positive binding activity (>2+) with PNA in the neoplastic epithelial cells. In the cases of borderline malignancy, only 3 of 9 revealed as much similar binding pattern with PNA as cystadenocarcinoma group, in contrast, minimal degree of positivity (1+) was noted in the remainder. These findings may suggest heterogeneity in the biochemical characteristics among the cases of borderline lesion. And it is proposed that the higher PNA binding cases in ovarian mucinous borderline malignancy require extensive sampling by multiple sections and further careful follow-up study.

PURPOSE: Postoperative long-term follow-up studies after orchiopexy are rare as compared for other studies such as for histological changes and proper operative age. We analyzed the five-year long-term follow-up results after orchiopexy, expecting a proper prognosis of testicular growth. MATERIALS AND METHODS: A total of 57 patients were selected from a follow-up study in 211 boys who underwent orchiopexy between January 1999 and July 2001. Patients were divided in several categories(operation age, testis consistency, pre-operational position of the testis) and were analyzed by examination of the previous medical records, preoperative and postoperative testicular volume(measured by ultrasonography), follow- up history taking, and from a physical examination. RESULTS: For the 57 patients, 14 patients had bilateral and 43 patients had unilateral cryptorchidism. All of the cryptorchid testes were smaller than a normal testis in the unilateral group of patients as determined by testis ultrasonography. Sorting by operation age, only patients that received orchiopexy within two years from birth showed a significant recovery of testicular volume percentage(operated testis/normal testis x100%: in the unilateral group) at follow-up. Sorting by consistency, the patients with normal testicular consistency showed a significant recovery of testicular volume percentage(operated testis/normal testis x100%: in the unilateral group) at follow-up. Sorting by the preoperative position of the testis, the proximity of the testis to the scrotum was a significant factor for recovery of delayed cryptorchid testicular growth. CONCLUSIONS: Orchiopexy performed at less than two years from birth and the proximity of the testis to the scrotum were significant factors for recovery of delayed cryptorchid testicular growth. Consistency of a cryptorchid testis can be a meaningful factor for expectation of testicular growth by the establishment of an objective measurement for testicular consistency and studies for histological correlation.

Lymphoid tumors of the orbit are rare, and sometimes it is not possible either clinically or histologically to differentiate between lymphoid tumor and pseudolymphoma. Some authors assert that the degree of cytologic differentiation appears to be the single most important factor for determining the prognosis of patients with orbital lymphoid lesions. However, the cytomorphologic basis is not so helpful to diagnose and classify our case, which shows some discrepancy between pathological findings and clinical and radiological findings. At first we misdiagnosed our case as orbital malignant lymphoma on the basis of cytomorphology and immunohistochemical study. But no responce to local intensive radiotherapy and the follow up study of the patient suggest orbital pseudolymphoma.
Follow-Up Studies

To treat intermittent exotropia, bilateral recession or monocular recession-resection can be chosen. Thirty one cases of intermittent exotropia with preoperative exoangle 25 delta were treated with 8mm bilateral recession (15 cases) and 5.5mm recession of lateral rectus muscle combined with 5mm resection of medial rectus muscle (16 cases). The final surgical results were compared between the 2 groups. The surgical results were as follows: in bilateral recession group, 33.3% was satisfactory, 60.0% undercorrected, and 6.7% overcorrected with 13.7 months of follow-up in average, in monocular recession-resection group, 50.0% was satisfactory, 18.8% undercorrected, and 31.3% overcorrected with 13.0 months of follow-up in average. Monocular recession-resection procedure had better satisfactory result than that of bilateral recession procedure. The author agrees the opmion that recession-resection produces a more permanent result than recession alone because the resection of the medial rectus muscle locks the eye in better alignment, preserving the benefit of the recessed lateral rectus muscle.
