1.Enteric Cyst in the Tongue.
Korean Journal of Pathology 1997;31(11):1237-1239
A case of enteric cyst in the anterior two-thirds of the tongue is reported. The patient, a 42 day-old female infant, presented with a protruding tongue mass since birth. Under the impression of ectopic thyroid gland or leiomyoma, complete resection was performed. The mass proved to be an enteric cyst, lined by small intestinal mucosa with an underlying coat of smooth muscle. Enteric cysts arising in the tongue is rare and only 8 such cases have been reported in the literature.

Angiogenesis depends on the net balance between positive and negative angiogenic factors. Tumor cells are angiogenic resulting from increased production of positive factors and decreased production of negative factors. Among these, vascular endothelial growth factor and glioma- derived angiogenesis inhibiting factor are related to glioblastoma multiforme. The p53 gene is more frequently mutated than any other known oncogene or tumor suppressor gene in human tumors including glioblastoma multiforme. Angiogenesis is reported to be controlled by p53 regulation in recent studies. To examine the effect of p53 overexpression on angiogenesis in glioblastoma multiforme, we performed immunohistochemical staining in 51 cases of glioblastoma multiforme, using monoclonal antibodies to p53 protein and factor VIII. 20 cases of low grade astrocytoma were used as control. p53 overexpression was present in 15(75%) of 20 cases of low grade astrocytoma and the mean vessel count was 37.7+/-9.9 at x200 field and 17.5+/-5.8 at x400 field. p53 overexpression was present in 35(68%) of 51 cases of glioblastoma multiforme and the mean vessel count was 91.9 45.8 at x200 field and 40.7 19.1 at x400 field. Mean vessel count in low grade astrocytoma with p53 overexpression was 39.4 10.2 at x200 field and 18.9 5.7 at x400 field, while in cases without p53 overexpression it was 32.4+/-7.6 at x200 field and 13.2 3.5 at x400 field. Mean vessel count in glioblastoma multiforme with p53 overexpression was 94.5+/-51.8 at x200 field and 42.1+/-16.8 at x400 field, while in cases without p53 overexpression it was 86.1+/-29.5 at x200 field and 37.1+/-16.8 at x400 field. The mean survival time was 12.4 months in the 39 cases of glioblastoma multiforme in which follow-up studies were possible. Significant prognostic factors were age, p53 overexpression and adjuvant therapy. These results show that p53 gene mutation is one of the many contributing factors to angiogenesis in glioblastoma multiforme. In addition, other oncogenes and tumor suppressor genes, as well as growth factors may be involved. Age, p53 overexpression and adjuvant therapy proved to be significant prognostic factors, while microvessel density was not.

Barrett's esophagus is a metaplastic process in which the squamous epithelium of the lowet esophagus is replaced by columnar epithelium. Most cases are believed to be related to prolonged gastroesophageal reflux. Detection of Barretts esophagus is important in that it results in adenocarcinoma in about 10% of patients. We report a case of adenocarcinoma arising from Barrett's esophagus in a 56 year-old man, diagnosed incidentally at a physical check-up. Grossly, the esophagogastric junction was irregular and there were two small ulcers in the lower esophagus. Microscopically, ihe squamous epithelium of the lower hagus was replaced by specialized intesinal mucosa with a small focus of adenocarcinona confined to the submucosa in one area. Many separate dysplastic foci were also present in the nearby esophageal mucosa.

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

Leiomyosarcoma(LMS) is a malignant tumor from smooth muscle origin that arises most commonly in the gastrointestinal tract and uterus, but rarely in the oral and maxillofacial area which lacks smooth muscles. 63 cases of oral LMS have been reported, especially LMS that occurred in the mandibular gingiva is only 2 cases. Major symptom of oral LMS is painful or painless swelling. Besides it, oral LMS has no specific characteristics. So it is difficult to diagnose the case as LMS of the oral cavity. Certain cases report that LMS of the oral cavity was misdiagnosed as periodontitis and the patients were treated with unnecessary procedures. Conventional treatment of LMS is the radical surgical excision. LMS that is infiltrative and very malignant has poor prognosis despite of well-circumscribed boundary. LMS of the oral cavity is often recurred, has high rate of distant metastasis and 5-year-survival rate is as low as 23%. This article reports LMS of the mandibular gingiva that treated with surgical intervention, had local recurrence and metastasis to the lymph node after 16-month's follow-up examination.

Late-onset focal dermal elastosis is a recently described disorder afflicting elderly patients with yellow papules on the neck and flexural areas. Although there are similar clinical findings to pseudoxanthoma elasticum, no stigmata of pseudoxanthoma elastimum are not evident. Histologically the papules are characterized by increased elastic fibers of normal appearance in the mid and deep dermis and no evidence of solar elastosis. Late-onset focal dermal elastosis may be caused by focal accumulation of normal appearing elastic tissue due to loss of age related homeostatic growth regulating gene control mechanism. We report a case of pseudoxanthoma elasticum-like late-onset focal dermal elastosis and suggest that this condition may be more common than has been reported.

Digital mucous cysts are observed frequently on the lateral or dorsal aspect of the digital fingers. Digital mucous cysts are prone to recur after simple excision, electrocoagulation, intralesional injection of corticosteroid and a variety of other therapeutic maneuvers. In this report, we describe one patient with digital mucous cyst who was successfully treated with intralesional injection of 1 mg/ml of minocycline hydrochloride without any sequelae.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.

9.Cervical intraepithelial neoplasia and cervical cytology in pregnancy
Journal of Pathology and Translational Medicine 2024;58(6):283-290
Cervical cancer screening during pregnancy presents unique challenges for cytologic interpretation. This review focuses on pregnancy-associated cytomorphological changes and their impact on diagnosis of cervical intraepithelial neoplasia (CIN) and cervical cancer. Pregnancy-induced alterations include navicular cells, hyperplastic endocervical cells, immature metaplastic cells, and occasional decidual cells or trophoblasts. These changes can mimic abnormalities such as koilocytosis, adenocarcinoma in situ, and high-grade squamous intraepithelial lesions, potentially leading to misdiagnosis. Careful attention to nuclear features and awareness of pregnancy-related changes are crucial for correct interpretation. The natural history of CIN during pregnancy shows higher regression rates, particularly for CIN 2, with minimal risk of progression. Management of abnormal cytology follows modified risk-based guidelines to avoid invasive procedures, with treatment typically deferred until postpartum. The findings reported in this review emphasize the importance of considering pregnancy status in cytological interpretation, highlight potential problems, and provide guidance on differentiating benign pregnancy-related changes from true abnormalities. Understanding these nuances is essential for accurate diagnosis and proper management of cervical abnormalities in pregnant women.
