title: Unusual Glomus Tumor of the Penis.
abstract: BACKGROUND
  Glomus tumors are benign neoplasms commonly found in subungual regions of the extremities and rarely located in the penis. Misdiagnosis of glomus tumors is common; therefore, symptoms and clinical presentations should be reviewed.
  
  
  OBJECTIVE
  The primary objective of this review article is to emphasize the pathogenesis, pathology, clinical presentation, symptoms, diagnosis, and treatment methods of glomus tumors in order to better identify and manage the condition.
  
  
  METHODS
  Research was conducted using PubMed/Medline. The inclusion criteria required glomus tumor to be present on the penis.
  
  
  RESULTS
  Glomus tumors, which appear as symptomatic or asymptomatic lesions, are attributed to dispersion grouping of neoplastic or non-neoplastic lesions in a particular area.
  
  
  CONCLUSIONS
  Differential diagnosis of glomus tumors includes hemangiomas, neurofibromatosis, epithelial lesions, and spindle-cell lesions. Physical examination and histological findings should be used for diagnosis. Treatment options can be either conservative or invasive, in which the patient undergoes surgical excision.
