Pulmonary blastomas are rare malignancies, representing 0.25% to 0.5% of all primary lung neoplasms with often aggressive progression and poor prognosis. Clinical management of pulmonary blastomas depends on histologic subtype, staging, and presentation, and may consist of surgery, chemotherapy, and radiation. Biphasic pulmonary blastoma is a subtype of pulmonary blastoma that exhibits biphasic histology, with both epithelial and mesenchymal malignant elements. We report a case of biphasic pulmonary blastoma in a 33-year-old female with 1 pack per day history of smoking for approximately 16 years, who presented with left-sided pleuritic chest pain on deep inspiration without otherwise significant pat medical history. Imaging evaluation using chest radiography, computed tomography, and magnetic resonance imaging identified a heterogenous, well-circumscribed, left lower lobe mass with extensive necrosis and hemorrhage. No lymphadenopathy or distant metastasis was detected through imaging evaluation. Surgical resection of the tumor followed by histopathological analysis confirmed a biphasic pulmonary blastoma.
Intervertebral disc calcification is rare in the pediatric population and is associated with sudden neurological manifestations. Although commonly symptomatic, conservative management yields excellent prognosis in the vast majority of cases. The following case illustrates the finding of intervertebral disc calcification in a patient with vertebral body segmentation anomaly consistent with Klippel-Feil Syndrome. As both entities are associated with potential neurological sequelae, this case of coexistent pathologies highlights the importance of recognizing the potential presence of intervertebral disc calcifications in pediatric Klippel-Feil Syndrome patients.
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.
