Abstract:
There are many classifications of jaw cystic formations. The most perfect is the International histological classification of odontogenic tumors, cystic lesions of the jaws and tumor-like processes, approved by WHO in 1971. According to WHO, the group of epithelial cysts includes both developing ones, including odontogenic (primordial or keratocyst, gingival, erupting, follicular) and non-ontogenic origin (nasopalatine duct, globular-maxillary, nasolabial or so-called naso-alveolar), and inflammatory (radicular) tumor-like formations.

Abstract:
Odontogenic Keratocyst is an aggressive odontogenic cyst with a high recurrence rate. After radicular and follicular cysts, odontogenic keratocysts are the third most common cyst of the jaws and approximately 12-14% of all odontogenic cysts. It has been retermed to Keratocystic odontogenic tumour (KCOT) as it better reflects its neoplastic nature but recently it has been re classified and retermed into the cystic category. Various surgical methods have been proposed but comparatively, conservative treatment options such as Dredging methods might be the treatment of choice due to preservation of anatomical structure. Objective: The aim of this study was to analyse the clinical, radiological and histopathological characteristics of Odontogenic Keratocyst and provide a proper management system affected by this type of lesions. Materials and methods: The prospective study was performed in Dhaka Dental College and Hospital from a period of January 2014 to January 2018. A total number of 75 patients were selected for this study based on clinical, radiological and histopathological confirmation of odontogenic keratocysts. The treatment options were enucleation, enucleation with curettage, enucleation with peripheral ostectomy, Dredging method and surgical resection. After treatment patients were followed up 1months, 3 months and 6 months in every year at least for 5 years. Results: Among 75 patient of odontogenic keratocyst; the mean age was 27.69±13.35 and age range was 11 to 66 years. Male were 53(71%) and 22 (29%) were female patients. 53 (70.67%) cases were found in the mandible, 15(20%) cases in the maxilla and in 7(9.33%) cases were involved in both maxilla and mandible; mandibular posterior region was the most specific region involved 37(69.81%).The most common clinical features revealed pain and swelling. Radiologically, 70.66% unilocular, 96% well defined and 94.66% radiolucent area were prominent. Bone expansion 37.38%, root resorption 30.00% and 36% were associated with an impacted tooth. Regarding treatment options enucleation with curatage 12%, enucleation, curettage & peripheral ostectomy 29.33%, Dredging 52% and surgical resection 6.6% was done. Recurrence occurred in 18 patients with recurrence rate of 24%. Conclusion: Odontogenic keratocyst is an aggressive cyst, male predominant, posterior mandible is the commonest site and well defined unilocular radiolucency are commonest radiological feature. Radical treatment options such as resection reduced the recurrences of the tumour but higher morbidity and jaw deformity. Comparatively, conservative treatment options such as Dredging methods might be the treatment of choice due to preservation of anatomical structure. A long term follow up is paramount importance for the research and understanding the clinical pattern, behavior, treatment and recurrence of the lesion. Update Dent. Coll. j: 2019; 9 (1): 8-15

Abstract:
AbstractPanfolliculoma is a rare follicular neoplasm with differentiation toward both upper (infundibulum and isthmus) and lower (stem, hair matrix, and bulb) segments of a hair follicle. We present an unusual case of cystic panfolliculoma. A 33-year-old Hispanic woman presented with an 8-month history of a 3.0-cm cystic scalp mass. The lesion was excised, and the histologic sections showed a cystic follicular neoplasm that contained corneocytes in basket-woven and laminated array, trichohyalin granules of the inner root sheath, germinative cells, papillae, matrical cells, and “shadow” cells. Cytokeratin 903 and cytokeratin 5/6 immunostains uniformly highlight the tumor cells. Ber-EP4 strongly labels the germinative cells but not the follicular papillae. CD34 labels the surrounding fibrotic stroma and focally the epithelial component.

Abstract:
ABSTRACT Cystic lesions are frequent in the oral cavity. They are defined as a pathologic cavity with or without fluid or semifluid material. Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin affecting the jaws. They are most commonly found at the apices of the involved teeth. This case report presents the successful surgical management of large infected radicular cyst involving entire body region of right side of mandible. We illustrate the possibility of healing of cystic periapical lesions with conservation of vital structures. How to cite this article Agarwal P, Sharma S, Trehan M, Vashistha A.

Abstract:
TNF-α is a pleiotropic cytokine that is considered as a primary modifier of inflammatory and immune reaction in response to various inflammatory diseases and tumour. We investigated levels of TNF-α in 43 radicular cysts and 15 odontogenic keratocysts, obtained from patients undergoing surgery, under local anaesthesia, and after aspiration of cystic fluid from non-ruptured cysts. TNF-α is elevated in both cysts’ fluid, but higher values were found in radicular cysts in comparison to keratocysts. The significantly higher concentration of TNF-α was associated with smaller radicular cysts, higher protein concentration, higher presence of inflammatory cells in peri cystic tissues, and the degree of vascularisation and cysts wall thickness (Mann-Whitney U-test, p<0.05). No correlation was found based on these parameters in odontogenic keratocyst, but all cysts have detectable concentrations of TNF-α. We here for the first time present that a difference in the concentration of TNF-α exists between these two cystic types.

Abstract:
In response to the prolonged increasing influence of the radicular cyst, there is an adaptive compensatory reaction of the adjacent bone tissue and periosteum located in the area of damage. However, in the available professional literature there is no data on the activity of the marker of osteoregeneration-alkaline phosphatase in the periosteum of the mandible, which is in the growth zone of osteoblastoclastoma. The purpose of the study: to study in a comparative aspect osteoregenerative activity of the periosteum of the mandibular bones affected by radicular cyst and cystic form of osteoblastoclastoma by using the histochemical method. Histochemical studies were performed in 10 patients with large radicular cysts (d>3.0 cm) located on the mandibles – 1st clinical group, and in 9 patients with cystic forms of osteoblastoclastomas, localized on the mandibles - 2nd clinical group. Determination of alkaline phosphatase in periosteal tissues of the mandible was performed by the method of simultaneous azo combination according to Kaplow. Prepared samples of histochemicals were studied under a light microscope, the received images were photographed. Digitized images of histochemicals were analyzed using the computer program ImageJ. The accumulation of alkaline phosphatase in the periosteum of the mandibular areas affected by osteoblastoclastomas is less intense compared to the process of synthesis of this enzyme in the periosteum of the mandible, which is affected by radicular cysts of large size. Osteoregenerative potential of periosteum of mandibular bones affected by radicular cysts is much greater than in the periosteum located in the growth zone of the cystic form of osteoblastoclastoma.

Abstract:
Background: Odontogenic cysts are defined as the epithelial cysts which arise from odontogenic epithelium and occur in tooth bearing regions of jaws. The objective of the present study was to analyze different histopathological types of cystic jaw lesions and to determine the distribution of their relative frequency according to site, sex, size and age group. Materials and methods: This study was a cross sectional hospital based observational study conducted in the Department of Pathology, Manipal Teaching Hospital. All cases with cystic jaw lesions on histopathology during the study period from January 2014 to December 2018 were included in the study. Results: Thirty-two cases of cystic jaw lesions were reported during the study period. Females were more commonly affected in our study with a male: female ratio of 1:1.9. The age range in the study was 9 to 71 years with a mean age of 33.3 years. The most frequent type was radicular cysts followed by dentigerous cysts, odontogenic keratocysts and cystic ameloblastoma. Radicular cysts showed the most female predilection with a ratio of 1:4.3. and a mean age of 35.6 years. Majority of dentigerous cysts were seen in patients below 30 years. Both radicular cysts and dentigerous cysts showed more involvement of maxilla but odontogenic keratocysts were more common in mandible Conclusions: The present study corroborate with other similar literature with respect to the frequency percentage of different types of jaw cysts.However, female predilection was seen in radicular and dentigerous cysts. Maxilla was the more common site except in odontogenic keratocysts.

Abstract:
Radicular cyst as the most common odontogenic cyst usually arises from residual epithelial cells stimulated by inflammatory factors initiating by pulpal necrosis of a non-vital tooth. Radicular cyst is commonly asymptomatic, slow grower, and rarely invade near bony structures. Many treatment approaches are presented for a radicular cyst like surgical endodontic treatment, tooth extraction, enucleation, and marsupialization. In this case treatment plan compromised with root canal therapy and surgical enucleation of cystic lesion. This case report presents a large radicular cyst in a vital maxillary first molar with only one necrotic root canal secondary to direct pulp capping with mineral trioxide aggregate with buccal and palatal cortical bone perforation.

Abstract:
The subject of this thesis is a method proposed for automated evaluation of the parameters of X-ray of cystic disorders in human jawbones. The main problem in medical diagnostic is the low repeatability due to the subjective evaluation of images without using a tool for image processing. In this thesis are described the basic steps of image processing, various methods of image segmentation and chosen segmentation method live-wire. Selected segments were processed in the ImageJ Java environment. In the cystic regions their basic statistical and shape properties were evaluated. The obtained values were used for learning the classification model (decision tree) in the environment RapidMiner. This model was used to create a plug-in for automatic classification of the type of cysts in the program ImageJ.

Abstract:
Odontogenic cysts and tumours arise from inclusion of tooth-forming epithelium and mesenchyme in the jaw bones during development. Cysts also arise from non-odontogenic epithelium trapped during fusions or from vestigial structures. In addition, bone cysts that can arise at other skeletal sites may also occur in the jaws. Odontogenic cysts and tumours may be classified according to their putative developmental origins and biology. The classification of jaw cysts is shown in Fig. 6.1. Odontomes are hamartomatous develop­mental lesions of the tooth-forming tissues. Odontogenic tumours are uncommon and are usually benign. Ameloblastoma is the most com­mon odontogenic tumour and is described in detail. The other odon­togenic tumours are rare and only the principal features are presented. Very rare congenital lesions of possible odontogenic origin are men­tioned in the final section. A cyst may be defined as pathological cavity lined by epithelium with fluid or semi-fluid contents. However, clinically, the term encompasses a broader range of benign fluid-filled lesions, some of which do not possess an epithelial lining. The preferred definition is, therefore, ‘a pathological cavity having fluid or semi-fluid contents that has not been created by the accumulation of pus’. Cysts are commonly encountered in clinical dentistry and are generally detected on radiographs or as expansions of the jaws. Most cysts have a radiolucent appearance and are well circumscribed, often with a corticated outline. At least 90% of jaw cysts are of odontogenic origin. The clinico-pathological features of jaw cysts are summarized in Table 6.1. The incidence of the four most common jaw cysts are provided in Table 6.2. The epithelial lining of odontogenic cysts originates from residues of the tooth-forming organ. • Epithelial rests of Serres are remnants of the dental lamina and are thought to give rise to the odontogenic keratocyst, lateral periodon­tal, and gingival cysts. • Reduced enamel epithelium is derived from the enamel organ and covers the fully formed crown of the unerupted tooth. The dentiger­ous (follicular) and eruption cysts originate from this tissue, as do the mandibular buccal and paradental cysts. • Epithelial rests of Malassez form by fragmentation of Hertwig’s epi­thelial root sheath that maps out the developing tooth root. Radicular cysts originate from these residues.

Abstract:
Introduction: Granulosa cell tumor (GCT) is an ovarian malignancy that arise from granulosa cells of the ovary. This tumour is a type of the sex cord-gonadal stromal tumour. GCT have good prognosis in comparison with other epithelial tumors. Methodology: Two cases of granulosa cell tumors were diagnosed in sir Ganga ram hospital, Rajendernagar, New Delhi in December 2015 and January 2016. The patient’s age, clinical manifestations, radiological and histopathological findings were evaluated. One was in perimenopausal age group and other case was in postmenopausal age group. The clinical manifestations were menorrhagia and abdominal pain. Ultrasonographically, in one case focal hypoechoic zone showing peripheral hypervascularity with possibility of old hemorrhage follicular cyst was seen and in other case of granulosa cell tumors was both solid and cystic areas were seen. Histologically, variety of patterns like diffuse, trabecular, nodular, sheets, nests and fascicular patterns with nuclear grooving in ovarian tissue. In addition endometrial findings were suggestive of simple hyperplasia without atypia. Treatment modalility used was surgery i.e., Total hysterectomy and bilateral salpingo-oophorectomy in both cases. Conclusion: Granulosa cell tumor of the ovary is a rare ovarian malignancy. Endometrial pathology to rule out endometrial carcinomaspecially when postmenopausal bleeding is concomitant finding is advised. Radical surgery is usually not required.
