Vulva syringomas are rare in reviewing literature. In our case, a 29-year-old had multiple papular lesions involving both sides of the vulva. Microscopically the lesion showed dilated cystic sweat ducts some of which have small comma like tails resembling tadpoles. It is the purpose of this report to present a rare case of syringoma which was limited to the vulva without involvement of other sites.

OBJECTIVES: To investigate the common causes of persistent septal deviation in revision septoplasty and to report the surgical techniques and results to correct them. METHODS: A total of 100 consecutive patients (86 males) who had revision septoplasty due to persistent septal deviation from 2008 and 2014 were included in the study. Their mean age was 35.6 years and the mean follow-up duration was 9.1 months. Presenting symptoms, sites of persistent septal deviation, techniques used to correct the deviation, and surgical results were reviewed. RESULTS: The mean interval between primary and revision surgery was 6.2 years. Forty-eight patients received revision septoplasty and 52 received revision septoplasty combined with rhinoplasty. Nasal obstruction was the most presenting symptom in almost all patients. The most common site of persistent septal deviation was middle septum (58%) followed by caudal septum (31%). Correcting techniques included further chondrotomy and excision of deviated portion in 76% and caudal batten graft in 39%. Rhinoscopic and endoscopic exams showed straight septum in 97% and 92 patients had subjective symptom improvement postoperatively. CONCLUSION: Middle septum and caudal septum were common sites of persistent deviation. Proper chondrotomy with excision of deviated middle septum and correction of the caudal deviation with batten graft are key maneuvers to treat persistent deviation.

Purpose:
To investigate changes in eye movement amplitude after conjunctival recession and conjunctivo-limbal autograft for treating recurrent pterygium with ocular motility restriction.
Methods:
We retrospectively analyzed 18 eyes of 16 patients who had recurrent pterygium with ocular motility restriction, who had received conjuntivo-limbal autografts from January 2011 to December 2019 and who had been followed-up for more than 6 months. We evaluated changes in eye movement amplitude, best corrected visual acuity, uncorrected visual acuity, corneal astigmatism and keratometry, and recurrence and complication rates before and after surgery.
Results:
The mean age of the patients was 63.9 ± 9.7 years. Eye movement amplitude increased significantly from 5.80 ± 1.70 mm preoperatively to 7.02 ± 1.37 mm postoperatively (p < 0.001). The mean UCVA increased from 0.67 ± 0.46 preoperatively to 0.36 ± 0.35 postoperatively (p < 0.001). The mean corneal astigmatism decreased from 3.51 diopters (D) preoperatively to 1.22 D postoperatively (p = 0.001). According to the power vector analysis, M and B were significantly reduced after the surgery, but the changes in J0 and J45 were not significant. No recurrence of pterygium was observed.
Conclusions
Eye movement amplitude for severe recurrent pterygium with symblepharon or ocular motility restriction quantitatively measured the range of ocular movement clinically and was applied to determine the severity of recurrent pterygium and predict the surgical outcome. Conjunctivo-limbal autograft for severe recurrent pterygium is thought to be a safe and effective surgical method because it solves the ocular motility restriction caused by adhesions and has low recurrence rates, although it requires the skilled experience and techniques of the operator and a long operation time.

We report a interesting case of malignant melanoma associated with squamous cell carcinoma, A 75-year-old woman has been suffered from a 4*3*3cm sized slowly growing protruding mass for 2 years based on the previous existing black or dark brownish colored round plaque on the left buttock since 10 years. A hard fixed lymph node is palpable on the left inguinal area. Biopsy specimens from the plaque and mass revealed typical findings of the superficial spreading malignant rnelanoma and squamous cell carcinoma. Simple mass excision and lymph node dissection were performed.

The mixed gangliocytoma-pituitary adenoma is a very rare intracranial neoplasm, and it is frequently associated with endocrine symptoms; acromegaly, Cushing's disease, galactorrhea and amenorrhea. Morphologically it shows a mixture of gangliocytoma and pituitary adenoma in various proportions. In the area of gangliocytoma, there is no neoplastic glial component. The portion of pituitary adenoma consists mainly of chromophobe cells. There are three hypotheses in its histogenesis. We report a case of a 41 year-old lady presented with acromegaly and amenorrhea existing for 3 years. On magnetic resonance image, there is a dumbell-shaped mass in the sellar region. Histologically it showed typical features of mixed gangliocytoma-pituitary adenoma. This case is presented in the view of its rarity and interesting possible histogeneses.

During tumor progression, a subset of cells acquires metastatic properties, presumably through a series of genetic alterations. As the result, cells detach from the primary tumor, penetrate the basement membrane and invade the adjacent structures including lymph and blood vessels. Loss of adhesive functions and gain of new adhesive functions are thought to play a crucial role in this metastatic cascade. Since tumor metastasis is the principle cause of death for cancer patients including colon cancer, there is a consensus that a search for tools that allow effective assessment of the metastatic potential of tumors is a prime goal for cancer research. An immunohistochemical study of cell adhesion molecules, CD44H and its variant CD44v6, was done to evaluate their relationship with known prognostic factors related to the progression and metastasis of colorectal carcinoma in 94 cases of colorectal carcinoma tissues. The results were as follows. The CD44H expression was detected in 90 (95.7%) and CD44v6 in 53 (56.4%) out of 94 cases of colorectal carcinoma, and the CD44H was overexpressed in tumor tissue more than in normal mucosa in 62% of the cases. The expression rates of both protein were not significantly correlated with age and sex of the patients, invasion depth, lymph node metastasis, tumor differentiation, and tumor site. The coexpression of CD44H and CD44v6 in tumor was significant (p<0.05). The above results suggest that overexpression of CD44H and loss of function to control the alternative splicing of CD44 mRNA resulting in CD44v6 expression and alteration of adhesive function are closely associated with tumorigenesis of the colorectum.

BACKGROUND: Recently technetium-99m sestamibi (99mTc MIBI), which dose not require withdrawal of thyroid hormone, has been used for imaging of thyroid carcinoma. The aim of this study was to determine the clinical usefulness of Tc MIBI scintigraphy after total thyroidectomy for thyroid carcinoma. The results were compared with those of standard 131I scintigraphy. METHODS: One hundred twelve patients with a median age of 44 years (range, 14-76 years) were included in the study. After optimal endogenous thyroid stimulating hormone stimulation (>50 mIU/mL), whole body scintigraphy using 4 mCi of 'I and 20 mCi of Tc sestamibi were done simultaneously. Concomitantly serum thyroglobulin and anti-thyroglobulin antibody levels were checked. If abnormal findings on any of the scintigraphic methods or high levels of thyroglobulin (> 10ng/mL) were detected, diagnostic imaging studies were done to confirm the existence of the disease. And high dose (150-200 mCi) 'I was administered as therapy and then whole body scans were performed again after the therapy. The presence or absence of thyroid cancer was established by pathologic, radiologic, and/or high dose I scan findings. RESULTS: In 11 patients, Tc MIBI scan revealed positive accumulations which were not found on 131I scan, of whom 6 had elevated thyroglobulin levels. In these cases, 5 cases were interpreted to have normal thyroid remnant and 6 cases showed pathologic findings (2 lung, 1 lymph node, 1 lung and lymph node, 1 local recurrent cancer, and 1 false positive accumulation of 99mTc MIBI). Metastasis or residual cancer were confirmed histologically in 1 and radiologically in 4 cases. Negative 99mTc MIBI scans, despite of positive I scans, occurred in 9 patients, of whom 2 had abnormal thyroglobulin levels. Seven cases were interpreted to have thyroid remnant, 2 cases were confirmed to have lung metastasis, and another one was misinterpreted due to breast shadow. CONCLUSION: In conclusion, these results suggest that 99mTc MIBI scan may have similar sensitivity and specificity for the detection of residual or metastatic differentiated thyroid carcinoma. The 99mTc MIBI scan, especially in cases of negative 131I scan despite of abnormal thyroglobulin levels, can be used as a very useful complementary diagnostic tool.

The cutaneous synthesis of vitamin D in response to ultraviolet radiation exposure is the most important factor in maintaining vitamin D balance in Man. The skin is not only the site of vitamin D synthesis, but also a target organ for calcitriol(1, 25-dihydroxy-vitamin D) which is naturally occuriag, hormonally active form of vitamin E. It is now known that calcitriol inhibits the proliferation of epidermal cells and induces her differentiation. In this study, epidermal keratinocytes and melanocytes were isilated from the neonatal foreskin, and were culturod using a MCDB 153 and modified TIC media, respectively. And then various concentratioris of calcipotriol(MC 903), a synthetic aralogue of calcitriol, were added to each culture. The effects of calcipotriol on the growth of human keratinocytes and melanocytes were investigated. The results were as follows : 1. The addition of calopotriol to human keratinocyte and melalocyte cultures inhibited their proliferation in a dosdependent manner. 2. Calcipotriol had no effects on the melanization process of the melanocyte. 3. Calcipotriol was found to inhibit the proliferation, however it induced the terminal differentiation of cultured keratinocytes, as judged by morphologicai changes. The decreased density of kerationcytes, The formation of cornified cells, and the cellular destruction in a concentration of 10 M of calcipotriol were observed. 4. By using the light atid the electron microscope, we observed that the epidermal thickness was decreased and terminal differentiation was facilitateir. Living Skin Equivalent (LSE) according to the increasing concentration of calcipotriol. A]i)parent cytotoxic effects were observed in 10 M, 10 M of calcipotriol. In summary, the above results indicate that the addition of calcipotriol to the in vitro culture system of human keratinocyte and melanocyte induces the biologic process of terminal differentiation of keratinocytes and inhibits proliferation of keratinoytes and melanocytes in a dose-dependent manner.
