Primary Leiomyosarcoma of the Glans

Area of Science:

• Oncology
• Uropathology
• Surgical Oncology

Background:

• Penile leiomyosarcoma is an exceptionally rare mesenchymal tumor originating from smooth muscle cells.
• Limited case studies result in equivocal guidelines for non-surgical treatment, prognosis, and overall management.
• Leiomyosarcoma exhibits a high recurrence rate among penile mesenchymal tumors, with deep subtypes being more aggressive and metastatic.

Observation:

• A rare case of a 54-year-old male patient diagnosed with deep localized leiomyosarcoma of the glans penis is presented.
• The tumor displayed superficial characteristics despite originating from the deep smooth muscle layer.
• This presentation deviates from typical deep subtype morphology.

Findings:

• The case underscores the aggressive nature of deep penile leiomyosarcoma and its potential for metastasis.
• Histopathological, clinical, and immunohistochemical features were analyzed.
• Early and aggressive surgical management is crucial for localized disease.

Implications:

• This case contributes to the limited literature on penile leiomyosarcoma, particularly the deep subtype with unusual presentation.
• Highlights the importance of considering aggressive surgical approaches for localized penile leiomyosarcomas.
• Further research is needed to establish definitive treatment guidelines and prognostic factors for this rare malignancy.
