Paratesticular superficial angiomyxomas: A case report

Area of Science:

• Dermatology
• Pathology
• Surgical Oncology

Background:

• Superficial angiomyxoma (SA) is a rare benign neoplasm originating in the superficial dermis or subcutaneous tissue.
• Characterized by abundant myxoid stroma and vascularity, SA typically presents as nodules on the trunk, head, or limbs.
• Literature review reveals a scarcity of reported cases, highlighting the rarity of this condition.

Purpose of the Study:

• To present a rare case of paratesticular superficial angiomyxoma in a 43-year-old male.
• To detail the diagnostic process and surgical management of this unusual presentation.
• To share therapeutic experience and emphasize strategies for preventing recurrence.

Main Methods:

• Surgical excision of the paratesticular mass.
• Histopathological analysis using hematoxylin and eosin staining for myxoid stroma.
• Immunohistochemical staining (CD34, desmin, estrogen receptor, vimentin, S-100) for differential diagnosis.

Main Results:

• Histopathology confirmed abundant myxoid stroma.
• Immunohistochemistry results supported the diagnosis of superficial angiomyxoma.
• The tumor was completely excised with a well-defined boundary.
• No recurrence was observed during a 3-year follow-up period.

Conclusions:

• Complete surgical resection, potentially including a margin of normal tissue, is crucial for preventing superficial angiomyxoma recurrence.
• This case underscores the importance of thorough histopathological and immunohistochemical evaluation for accurate diagnosis.
• Successful complete excision led to a favorable long-term outcome without recurrence.
