Malignant glomus tumor in pleural cavity

Synchronous primary glomus tumor in a patient with adenocarcinoma of the ipsilateral lung

Glomus tumors are rare mesenchymal neoplasms arising from the glomus bodies in the deep dermis of the extremities or derive from the modified smooth muscle cells of the normal glomus body. Primary pulmonary glomus tumors are particularly rare and infrequently reported. We report a case of a primary glomus tumor occurring in the lung with adenocarcinoma in the ipsilateral lung as synchronous lung cancers in a 69-year-old man. He underwent lobectomy for adenocarcinoma and wedge resection for the glomus tumor with mediastinal lymph node dissection and was doing well without recurrence or metastasis at the last follow-up.

Unusual Glomus Tumor of the Penis

INTRODUCTION

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.

MATERIALS AND 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.

CONCLUSION

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.
