Background: Adult-type rhabdomyoma (ATR) is a rare mesenchymal tumor of skeletal muscle differentiation. Extracardiac ATR occurs most commonly in the head and neck, but do so in a heterogeneous fashion, arising at numerous different locations within this region.
Methods: At our institution, we encountered a patient who was diagnosed clinically with parathyroid adenoma based on signs and symptoms of hyperparathyroidism and suggestive radiologic findings. A parathyroidectomy with intraoperative consultation was performed.
Results: The frozen section diagnosis was ambiguous and a diagnosis of ATR was only made on permanent section.
Conclusion: Awareness of this tumor can prevent incorrect diagnosis and overtreatment intraoperatively. Herein, we describe the clinical history, pathologic findings, and review histologic features of rhabdomyomas.
