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.

Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

01:23Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
