Korean Journal of Pathology 1986;20(2):240-242
Apocrine carcinoma is a rare type of mammary cancer, which shows partial or total apocrine differentiation in either ductal or lobular carcinoma. The malignant transformation of apocrine epithelium of the breast was first described by Krompecher in 1916. It is well known that their relationship to true apocrine glands of the skin is only a morphological similarity, and this histological difference does not affect the prognosis. The authors experienced two cases of apocrine carcinoma of the breast which involved infiltrating ductal carcinoma of a 64-year old woman and intraductal carcinoma of a 69-year old woman respectively. Electron microscopic examination and brief review of literature was done.

Lawsonia intracellularis is not culturable with a standard bacteriologic culture. One step PCR assay as a clinical diagnostic method was developed for the rapid detection of porcine proliferative enteritis (PPE) caused by L. intracellularis. Primers were designed based on the p78 DNA clone of L. intracellularis. The one step PCR resulted in the formation of a specific 210-bp DNA product derived from L. intracellularis. The nonspecific amplification product was not detected with swine genomic DNA or other bacterial strains causing similar symptoms to L. intracellularis infection. The one step PCR was as sensitive as 100 pg of L. intracellularis genomic DNA. We applied this method to field specimens diagnosed as PPE by macroscopic observation. Of 17 mucosal scraping specimens, 16(94%) were identified as positive to PPE and 15(88%) of 17 feces specimens. These results suggest that the one step PCR can be used as a rapid diagnostic method for L. intracellularis infection.

3.Perioperative management of facial reconstruction surgery in patients with end-stage renal disease undergoing dialysis
Archives of Craniofacial Surgery 2024;25(2):71-76
Background:
The rising incidence of dialysis-dependent end-stage renal disease (ESRD) has underscored the need for collaboration between plastic surgeons and nephrologists, particularly concerning preoperative and postoperative management for facial reconstruction. This collaboration is essential due to a scarcity of comprehensive information in this domain.
Methods:
A study initiated in January 2015 involved 10 ESRD cases on dialysis undergoing Mohs micrographic surgery for facial skin cancer, followed by reconstructive surgery under general anesthesia. To ensure surgical safety, rigorous measures were enacted, encompassing laboratory testing, nephrology consultations, and preoperative dialysis admission. Throughout surgery, meticulous control was exercised over vital signs, electrolytes, bleeding risk, and pain management (excluding nonsteroidal anti-inflammatory drugs). Postoperative assessments included monitoring flap integrity, hematoma formation, infection, and cardiovascular risk through plasma creatinine levels.
Results:
Adherence to the proposed guidelines yielded a notable absence of postoperative wound complications. Postoperative plasma creatinine levels exhibited an average decrease of 1.10 mg/dL compared to preoperative levels, indicating improved renal function. Importantly, no cardiopulmonary complications or 30-day mortality were observed. In ESRD patients, creatinine levels decreased significantly postoperatively compared to the preoperative levels (p< 0.05), indicating favorable outcomes.
Conclusion
The consistent application of guidelines for admission, anesthesia, and surgery yielded robust and stable outcomes across all patients. In particular, the findings support the importance of adjusting dialysis schedules. Despite the limited sample size in this study, these findings underscore the effectiveness of a collaborative and meticulous approach for plastic surgeons performing surgery on dialysis-dependent patients, ensuring successful outcomes.
4.Histopathologic Characteristics of Conjunctivochalasis.
Journal of the Korean Ophthalmological Society 2013;54(8):1165-1174
PURPOSE: In this study we investigated the histopathologic characteristics of conjunctivochalasis and its association with lymphangiectasis using impression cytology and conjunctival excisional biopsy in patients with conjunctivochalasis. METHODS: This prospective study included 14 outpatients diagnosed with conjunctivochalasis, and who had excisional biopsies performed between March 1, 2012 and November 30, 2012. Preoperative slit-lamp examination, dry eye diagnostic test and impression cytology were also performed. For histological analysis, conjunctival sections were stained with hematoxylin and eosin (H&E), Verhoeff-van Gieson (VVG) elastic staining, and monoclonal antibody D2-40, a lymphatic endothelial marker. RESULTS: Tear break-up time and Schirmer's value were decreased in patients with conjunctivochalasis. Impression cytology showed a decrease in goblet cell density and an increase in nucleoplasmic/cytoplasmic ratio. The patients' conjunctival tissues exhibited an infiltration increase of chronic inflammatory cells on H&E stain, and a decrease in collagen density with degeneration of elastic fibers on VVG stain compared to tissues from the control subjects. D2-40 immunohistochemistry revealed the dilated subconjunctival lymphatics in patients with conjunctivochalasis. CONCLUSIONS: This study suggests that the characteristic histopathological features of conjunctivochalasis include dilated lymphatic vessels as well as decreased goblet cell and collagen densities with degeneration of elastic fibers.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

We have investigated the changes of DNA ploidy and S-phase fraction in proliferative lesions of rat liver. Proliferative lesions were induced by diethylnitrosamine and partial hepatectomy. DNA ploidy was measured by flow cytometer, and S-phase fraction was measured by in situ bromodeoxyuridine(BRdU)-anti BRdU monoclonal antibody techniques. Normal liver and initiated lesion revealed DNA diploidy or DNA tetraploidy. Hepatocyte nodule (NODULE) and hepatocelular carcinoma (HCC) revealed DNA diploidy, tetraploidy or aneuploidy. S-phase fraction was 1.0+/-0.9, 1.0+/-0.9m 3.7+/-2.3, 5.5+/-4.9, and 13.8+/-11.6 in normal liver, initiated lesion, NODULE not associated with HCC, NODULE associated with HCC, and HCC, respectively. In NODULE associated with HCC, it was widely distributed, ranging from 0.8 to 15.5%. In conclusion, S-phase fraction appeared to be increased as the hepatocarcinogenesis proceeded, but DNA ploidy did not. There was a heterogeneity of DNA ploidy and S-phase fraction in the proliferative hepatic lesions.

Local cutaneous reactions have been reported at injection sites of interferon therapy, but these are usually erythema or rarely induration. Skin necrosis at the injection site is rare. We describe here a patient with multiple sclerosis who presented with cutaneous necrosis at the injection sites of interferon-β. Biopsy of the necrotic lesion showed dermal vessel thrombosis and complete ischemic coagulative necrosis of epidermis and dermis.

Journal of the Korean Ophthalmological Society 2003;44(7):1504-1511
PURPOSE: We analyzed the effect of amniotic membrane transplantation and limbal autograft or allograft simultaneously for recurrent pterygium or pseudopterygium. METHODS: Total 15 cases of recurrent pterygium and 4 cases of pseudopterygium were surgically managed during September 1998 to June 2002. After excision of pterygium and subconjunctival fibrovascular inflammatory tissue in nasal area to 6-12 o'clock and up to equator of the eyeball, amniotic membrane was grafted on bare sclera and then limbal tissue was transplanted. Recurrence and complications of surgical management were evaluated for 8 months of mean follow-up period. RESULTS: Recurrence was not noted in 15 of 19 eyes, the other 4 eyes were recurred limited in the sclera. Mean epithelial regeneration period was 18 days, and diplopia and extraocular muscle limitation were disappeared after surgery. CONCLUSIONS: In spite of difficulties of surgical technique and long operation time, amniotic membrane transplatation with limbal graft in recurrent pterygium or pseudopterytium has low recurrence rate and aesthetic benefit. We suggest that amniotic membrane transplantation with limbal graft and will be useful and safe surgical method for pterygium with high recurrence rate.

Journal of the Korean Ophthalmological Society 2003;44(8):1741-1747
PURPOSE: We report the clinical efficacy of amniotic membrane transplantation which dyed by Chinese-ink and Davidson marking dye in patients of bullous keratopathy. METHODS: We performed permanent amniotic membrane transplantation in 23 eyes with bullous keratopathy during the period of October 1998 to May 2002. Simple amniotic membranes were transplanted in 9 eyes, Chinese-ink dyed amniotic membranes in 10 eyes, and Davidson marking dyed amniotic membranes in 4 eyes. RESULTS: 23 eyes were successfully transplanted by amniotic membrane. Most of patients with photophobia, pain, cosmetic problem had been satisfactory effects in Chinese-ink and Davidson marking dye groups and Davidson marking dye groups noted longer staining than Chinese-ink group. CONCLUSIONS: We suggest that dyed amniotic membrane transplantation may be effective method to release pain, photophobia, and cosmetic problem by stabilization of corneal surface than previous simple amniotic membrane transplantation in bullous keratopathy.
