A report about a rare case of tail gut cyst (TGC) in a 90-year-old man with sacrum ulceration

مقدمه: تیلگات کیست (Tailgut cyst=TGC) یک ضایعه کیستیک غیر شایع با منشا بقایای رودهPostnatal است که در فضای خلف رکتوم ایجاد می گردد. گزارش مورد: آقای 90 ساله اهل میناب با شکایت زخم در ناحیه ساکروم در مرکز آموزشی درمانی شهید صدوقی یزد پذیرش شد. بیمار در گرفتن شرح حال همکاری لازم را نداشت. بعد از انجام آزمایشات معمول، بیمار تحت عمل جراحی قرار گرفت و ناحیه مربوطه از نظر ترشحات تخلیه و ترمیم شد و طی عمل جراحی به توده ای در ناحیه ساکروم برخورد گردید، بعد از برش کامل و خارج کردن آن در بررسی آسیب شناسیTGC تشخیص داده شد. نتیجه گیری: با اینکه بروز بدخیمی در تیلگات کیست نادر است ولی باید در تشخیص افتراقی، تمام تومورهای خلف رکتوم به ویژه در زنان میانسال مورد توجه قرار گیرد

Investigation of Land Use Changes in North of Iran Using Remote Sensing and Geographical Information System (1986-2015)

Deforestation in Iran has been more rapid in the past 50 years than at any time in Iran’s history, and Neka basin located in the north of Iran has been subjected to severe deforestation problems. Detection of ecosystem changes may help decision makers and planners to understand the factors in land use and land cover changes in order to take effective and useful measures. Using remote sensing and GIS technologies are used as efficient tools for monitoring and evaluation land use change. In recent years, a considerable land use changes have occurred in in the Neka basin. This paper presents findings of an evaluation study that focused on the changes in land use changes in a great basin of Neka. The study was based on a spatial analysis of historical Landsat images (1986–2015) and several field measurements and observations. First, geometric correction and contrast stretch are applied. In order to detect and evaluate land use changes, image differencing, vegetation change analysis, principal component analysis and classification comparison have been applied. Finally, the results of land cover classification for three different times are compared to reveal land use changes. Relatively, agriculture, range and urban developed areas increased, respectively 84.70, 31.88 and 54.52 % from 1986 to 2015, while forest decreased 44.35%. With the greatest decrease occurring from 1991 to 1999. The overly analysis of the four land cover maps revealed that there is an imbalance in the spatial distribution of deforestation areas. The west and central part of the study area has mostly changed and deforestrated.From 1986 to 2015, forest, which covered 1245.53 km2 (47.79%) of the total area in 1986 had decreased to 693.60 (25.60.7%) in 2015. However, the rangelands increased from 1120.42 ha in 1986 to 1477.69 km2 in 20015. 

Clinico-pathological Features and Survival Time of Papillary Thyroid Carcinoma in Patients With and Without Hashimoto’s Thyroiditis: A Cross-sectional Study

Objectives: Researchers have reported different results regarding the association between Hashimoto’s disease and papillary thyroid carcinoma (PTC). Some believe that the coexistence of these diseases can lead to fewer tumor invasion and recurrence rates. This study evaluated the clinico-pathological features and survival time of PTC in patients with and without Hashimoto’s thyroiditis. Materials and Methods: In this cross-sectional study, medical records of 251 participants who underwent total or subtotal thyroidectomy due to PTC from 2012 to 2019 were reviewed. The clinico-pathological features of participants, such as age, gender, tumor stage, tumor size, lymph node involvement, metastasis, capsular invasion, single or multi-focal tumor status, and survival time were recorded from their medical records and pathology report and compared in two groups with and without Hashimoto’s thyroiditis. Results: From 251 participants, 92 (36.6%) had Hashimoto’s thyroiditis, whereas 159 (63.4%) did not show any signs of this disease. Fifteen participants in the Hashimoto group and 46 in the non-Hashimoto group had a recurrence. Although there were no significant differences between the two groups in the term of recurrence rate (P = 0.08), the mean survival time was significantly difference between the two groups (69.03 and 58.78, respectively; P = 0.038) Conclusions: Results of the study revealed that Hashimoto’s thyroiditis could increase the survival time of patients with PTC

Laryngeal Chondrosarcoma Arising From Cricoid Cartilage: A Case Report

Laryngeal chondrosarcoma is a rare tumor that involves head and neck region such as larynx in rare cases. This malignant tumor usually grows quite slowly. The patient may experience symptoms for several years before a diagnosis is made. The diagnosis is achieved by clinical, radiological and pathological features. Management is basically surgical. Prognosis is generally good, depending basically on histologic grade. Herein, we report a case of laryngeal chondrosarcoma presented with hoarseness. Spiral CT scan demonstrated an expansile mass with calcification originating from cricoid cartilage. The patient underwent surgery for open excisional biopsy, and postoperative histopathologic evaluations confirmed "laryngeal chondrosarcoma" as definite diagnosis. The patient denied total laryngectomy for complete removal of the tumor. Six months follow up showed no more growth

Skin mucormycosis presenting as an erythema-nodosum-like rash in a renal transplant recipient: a case report

<p>Abstract</p> <p>Introduction</p> <p>Cutaneous mucormycosis is a rare entity related to kidney transplantation. It usually presents with ecthyma-like lesions and black necrotic cellulitis. We report an unusual case of primary cutaneous mucormycosis presenting as erythema-nodosum-like lesions in a woman who had received a renal transplant.</p> <p>Case presentation</p> <p>A 49-year-old woman with diabetes received a living-unrelated kidney transplant. Her clinical course was uneventful for the first six months after transplantation. She then developed multiple, painful, erythema-nodosum-like lesions on her right leg and thigh following an episode of minor trauma. Mucormycosis was diagnosed by skin biopsy. Microscopic examination also showed panniculitis. The patient was treated successfully with amphotericin B and surgical resection. To our knowledge, this is the first description of primary cutaneous mucormycosis with erythema-nodosum-like lesions and panniculitis after renal transplantation.</p> <p>Conclusion</p> <p>Cutaneous mucormycosis should be considered in the differential diagnosis when a kidney transplant recipient develops erythema-nodosum-like lesions with panniculitis.</p

Evaluation of compliance between the results of Pap smear test and pathological specimens sent to the pathology department of Shaheed Sadoughi hospital in Yazd city in 2011-2014

AbstractBackground and Aim:Pap smear test is the most effective and appropriate screening method for cervical cancerprevention. This technique, due to early detection power in early stage of invasive cancers, causesdecreased mortality of cervical cancer. The purpose of this study was to assess the compliancebetween the results of Pap smear test with biopsy specimens sent to the pathology department of theShaheed Sadoughi hospital.Materials and Methods:In this cross sectional study, 145 cytology and pathology specimens that was sent to the pathologydepartment of the Shaheed Sadoughi hospital were selected. Agreement between the result ofcytology test and pathology was analyzed with statistical software SPSS and kappa agreement test.P&lt;0.01 was considered statistically significant.Results:The result of cytology and pathology showed that there is a little agreement between cytology andpathology results (P&lt;0.01, K: 0.26).Conclusion:According to the results, low levels of agreement was observed between the result of pop smear testand pathology results. Therefore to promote quality of cytological reports, the improvement ofperformance of midwives, cytologist and resident are recommended.Key words:Uterine cancer; Pap-smear; Biops

Familial Amyloidosis Cutis Dyschromica: a Case Report

Amyloidosis cutis dyschromica (ACD) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. Here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. Five other members of her family are also involved. Biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorphous eosinophilic masses stained positive with Congo red in the papillary dermis. The histopathologic findings were consistent with amyloidosis cutis dyschromica. Other investigations were normal. Dermatologists should consider amyloidosis cutis dyschromica when visit a patient with diffuse hypo and hyperpigmentation
