Introduction: Ovarian teratomas include mature cystic teratoma (MCT), immature teratoma (IT) and monodermal teratoma (MoT). Malignant transformation (MT) can occur in MCT and MoT, which remains a diagnostic challenge. Aims & Objectives: To discuss the morphological spectrum of ovarian teratomas reported during the last six years at our specialized diagnostic institute and determine the frequency of MT in MCT and MoT. Place and duration of study: The study was carried out at Chughtai Institute of Pathology from January 2015 to December 2020. Material & Methods: A retrospective study was performed by retrieving 1018 cases of ovarian teratomas reported in last 6 years. SPSS version 20 was used for data analysis. Results: MCT was most frequent ovarian teratoma with frequency of 95.6% (n=973), 2.26% (n=23) being IT and 2.16% (n=22) being MoT. IT were mostly seen in pediatric age group. MT in benign MCT was seen in 0.72% of MCT (n=7). Squamous cell carcinoma was most frequent malignancy 71.4% (n=5). One case of MoT also showed MT into papillary thyroid carcinoma, classic type, with frequency of MT in Mot being 4.76% (n=1). All MT in MCT had age >30 years which was a significant finding (p <0.001). Conclusion: Ovarian masses in postmenopausal patients with suspicious radiological features, irrespective of lesional size warrant a thorough gross examination, extensive sampling and a careful microscopic evaluation.

Chondromyxoid fibroma (CMF) is a rare benign bone tumor of cartilaginous origin, with an extremely rare craniofacial occurrence. Considering its rarity, craniofacial CMF presents a diagnostic challenge for radiologists. To our knowledge, only seven cases of zygomatic CMF have been described in the literature, only one of which was in the paediatric age group. Furthermore, none of the currently reported cases include MRI findings of zygomatic CMF. Here, we present a paediatric case of CMF of the zygoma with a comprehensive literature review of the reported cases, focusing on their radiological features and its differential diagnosis.

Background: Teratomas are belonging to a group of germ cell tumors. It is also referred to as dermoid cyst. Teratomas are most common germ cell tumor of the ovary. Teratomas are composed of various histological types. In this article we are presenting various morphological patterns, its clinical manifestation and its clinical significance.Methods: This is prospective study for a period of 3 years from March 2016 to February 2019 at tertiary care hospital. It consists of total evaluation of 82 cases of ovarian lesions which were surgically excised for clinically or radiologically suspected of ovarian neoplasm.Results: A total of 82 cases of ovarian specimen were included out of which 18 cases were of ovarian teratoma. In these 17 cases were benign teratomas, 1 case of immature teratoma. All the cases of mature teratoma were predominantly of cystic type with focal solid areas. Right sided ovary was involved in44.5% cases while left sided in 55.5% cases. The tumor size ranges from 2.5 cm to 20.8 cms. The age range in this study was from 20 to 60 year. The common age observed for ovarian teratoma was in group of 31-40 years, having 6 cases. The clinically most of cases were asymptomatic or presented with unexplained abdominal pain or palpable mass. USG finding in most of cases were diffuse or partial echogenic mass lesion with cystic nature and echogenic bands.Conclusions: In our study showed mature cystic teratoma is the most common type of ovarian teratomas. The immature and monodermal types are rare. The histopathological examination plays important role in final diagnosis   and patient management.

AbstractAtypical brain infections in the pediatric age group are uncommon and different from the adult population; however, when present, they pose a diagnostic challenge and can result in serious and potentially fatal complications if not recognized and treated early in the course of the disease. Imaging plays a vital role because of relative inaccessibility to tissue sampling. This review article regroups the atypical pediatric brain infections (parasitic, fungal, viral, and bacterial) by age group (prenatal, perinatal, and post-neonatal period) and elucidates their characteristic imaging appearance, as well as focuses on their complications, in an aim to help clinicians (pediatricians/pediatric neuroradiologists/radiologists) better characterize, diagnose, and guide patient treatment. In addition, this review article also emphasizes on infection mimics of the central nervous system in order to empower our differential diagnosis, improve our diagnostic accuracy, and avoid unindicated patient management and treatment.

Ovarian teratomas are the most common germ cell tumors and are classified as mature, immature and malignant.Mature cystic teratomas, also called dermoid cysts, are the most common germ cell tumour, accounting for upto 70% of benign ovarian masses in the reproductive years and 20% in postmenopausal women.Immature ovarian teratoma affects primarily younger patients and mature cystic teratomas seen in reproductive age groups. This case report provides a brief summary of the clinicopathological features of the ovarian teratomas such as, the immature teratoma which being a rare tumour was diagnosed in a 15 year old adolescent girl, managed surgically by laparotomy followed by chemotherapy, and the other case of a benign mature cystic teratoma in an elderly 52 year old postmenopausal woman, managed surgically although benign cystic teratomas are rare in the postmenopausal age group.

Mature cystic teratoma is the most common kind of ovarian germ cell tumor. Malignant transformation is uncommon, with thyroid cancer rarely found. Papillary thyroid microcarcinoma has rarely been described as associated with ovarian teratomas. We report a case of a 34-year-old woman who presented with abdominal pain and an ovarian mass. After surgery, the patient was diagnosed with a follicular variant papillary thyroid microcarcinoma that arose within a mature cystic ovarian teratoma. Based on the small size of the primary lesion and patient preferences, no further treatment was performed. To our knowledge, this is the third reported case of papillary thyroid microcarcinoma arising within a mature ovarian teratoma without struma ovarii. There is no consensus on the surgical approach and postoperative management of this condition. Whether further therapy with total thyroidectomy and radioiodine ablation may be beneficial is unknown. In conclusion, papillary thyroid microcarcinoma can also arise within mature ovarian teratomas. Although a favorable prognosis is anticipated, there is limited information about its history or prognosis.

Background Primary Rosai-Dorfman disease of bone is a rare disorder. Radiologic and clinical evaluation is insufficient in differentiating malignancy from these lesions. Methods We present a talar lesion in a 17-month-old boy who presented with deterioration in gait pattern, limping, pain, and swelling of the left ankle of 4-months' duration. Curettage and demineralized bone matrix grafting were performed. Results At 1 year after surgery, complete clinical and radiological healing was obtained. Conclusions Primary RDD of bone may present a diagnostic challenge. The condition must be included in the differential diagnosis of lytic or lucent lesions of the skeleton. Curettage and grafting provide satisfactory outcomes in talar RDD lesion in the pediatric age group.

Congenital lumbar hernias are uncommonly seen in the pediatric age group, with only about 60 cases reported in the literature. It is usually accompanied by a multitude of congenital anomalies involving different organ systems of the body. For instance, it may involve the ribs, spine, muscles, and the kidneys. Herein, we report a case of congenital lumbar hernia in an 8-month-old boy who underwent an operative repair using a mesh with an uneventful outcome.
