Adenocarcinomas are the most prevalent kidney neoplasms. Only a few cases of primary squamous cell carcinoma have been reported.It is responsible for 6–15% of all kidney tumors. Majorly found in males as compare to females. This case report is of is of A 65-yearold man with pain on the left side of his abdomen. CT Urography showed the right kidney measuring 11.2 x 4.9 cm and striatednephrogram in initial images with evidence of multiple non enhancing areas with peripheral enhancement, largest measuring 2.2 x 1.2cm. Mild thickening of the renal pelvis is noted. Presence of diffuse tumor ranging from size 15 x 8 x 7 cm occupying almost whole ofthe kidney with unattainable origin was observed. Primary renal squamous cell carcinomas are extremely rare tumours that are rarelysuspected or identified clinically. It is an important factor to consider while making a diagnosis of kidney tumours.
Aneurysmal bone cysts are blood-filled lesions of the bone that are benign, expansile, aggressive, and locally damaging. They havean atypical presentation and an unknown etiology. We present the case of a 17-year-old male youngster who appeared with a historyof trauma that resulted in a pathological left femur fracture. A subtrochanteric fracture complicated a slowly forming aneurysmalbone cyst in the proximal femur. Excision of the tumor with curettage and open reduction with internal fixation with a titanium elasticnail were successful treatments, and the empty space was replaced with bone graft from the left iliac crest. The gold standard fordiagnosis is a biopsy. Bone grafting should be used in conjunction with fracture fixation to achieve bony union.
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.
