Phosphaturic mesenchymal tumor of the nasal cavity: Clinicopathologic correlation is essential for diagnosis
We present a case of a 66-year-old female who presented with osteomalacia-related symptoms and was found to have a nasal cavity mass. Histopathologic examination was suggestive of PMT but certain characteristic features were lacking, requiring confirmation of the diagnosis by chromogenic in situ hybridization (CISH) assay for FGF23 mRNA. The patient's symptoms and laboratory abnormalities resolved upon resection of the tumor. (Source: Human Pathology: Case Reports)

A unique case of esophageal carcinosarcoma with histopathological diversities
We report a 57-year-old Japanese male with esophageal carcinosarcoma with histopathological diversities. The patient complained of dysphagia. Endoscopy of the upper gastrointestinal tract revealed a mass in the lower esophagus just above the esophagogastric junction. Pathological diagnosis of the biopsy was poorly differentiated squamous cell carcinoma/undifferentiated carcinoma. Preoperative chemotherapy was performed with poor response. Post-operative analyses revealed that the chest CT showed the appearance of mineralization after neoadjuvant chemotherapy. Surgery revealed a mass in the lower esophagus invading the esop...
