Ameloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not undergone differentiation to the point of hard tissue formation. Granular cell ameloblastoma is a rare condition, accounting for 3-5% of all ameloblastoma cases. A 30-year-old female patient presented with the chief complaint of swelling at the right lower jaw region since 1 year. Orthopantomogram and computed tomography scan was suggestive of primary bone tumor. Histopathologically, diagnosis of granular cell ameloblastoma of right mandible was made.
Squamous cell carcinoma of the kidney is a rare malignancy, usually not suspected clinically because of the lack of any pathognomic sign and ambiguous clinical and radiological features, and thus, patients present at advanced stages resulting in poor prognosis. We report here four cases of incidentally diagnosed primary renal squamous cell carcinoma that were treated at our hospital. The mean age of the patients (two females and one male aged above 60 years, except one male whose age was 25 years) was 60 years. Both the males and one of the females had a history of multiple renal calculi, and the other female had staghorn calculus. Interestingly, renal carcinoma was not suspected clinically in all these patients. In one case, a computerized tomography scan (CT scan) showed suspicious mass. All underwent nephrectomy for the non-functioning kidney. In only two cases, tumor was identified on gross examination, whereas the other two only showed a distorted pelvis. Our case series emphasizes the need for pelvicalyceal biopsy during diagnosis and treatment for long-standing nephrolithiasis and thorough sampling of nephrectomy specimens of such patients to rule out malignancy.
Introduction: Meningiomas are tumors that arise from the meningothelial cells. They are commonly located at intracranial, intraspinal or occasionally ectopic site. They show histological diversity and are categorized into three grades. This grading helps in predicting their behaviour and deciding treatment strategy. Aims and Objectives: To study the incidence, anatomical location, sex and age Predilection, histological variants and grading of meningiomas based on WHO 2016 classification. To correlate clinical features and radiological findings with those of histopathological findings. Materials and Methods: The study is carried out in the Department of Pathology, Dhiraj General Hospital, Piparia from November 2016 to July 2018. 30 tumors specimen diagnosed as meningioma by radiology and neurosurgery department, sent to department of pathology were included in the study. Analysis of histological features, typing and grading of all cases was done according to WHO 2016 classification of meningioma. Results: Total 30 meningioma tumors were included in the study. Most of them were intracranial, predominantly involving the posterior fossa of brain, females and the 41-60 age group. The most common histological subtype was psammomatous followed by meningothelial. Majority (93.33%) were benign grade I tumors. In 90% cases radiological diagnosis matched exactly with histopathological diagnosis. Conclusion: Meningiomas are slow growing tumors arising from the meningothelial cells accounting for 15-30 % of all CNS neoplasms showing a variety of histological patterns, more common in women, predominantly Grade I tumors. Recurrence of tumors depends on histological grade and extent of surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
