Dermal angiomyoma of the upper extremity

Area of Science:

• Dermatology
• Surgical Pathology
• Oncology

Background:

• Dermal angiomyomata are rare benign tumors.
• They can present as painless masses in the extremities.
• Understanding their prevalence and characteristics is crucial for diagnosis.

Purpose of the Study:

• To report the incidence and characteristics of dermal angiomyomata in the upper extremity.
• To highlight the importance of considering dermal angiomyomata in the differential diagnosis of upper extremity masses.
• To inform surgeons about this rare lesion.

Main Methods:

• Retrospective review of 85 cases of dermal angiomyomata.
• Analysis of lesion location, patient demographics, and clinical presentation.
• Documentation of any recurrence or malignant transformation.

Main Results:

• Twenty-four percent (24/85) of dermal angiomyomata were located in the upper extremity distal to the elbow.
• Lesions were more common in women (13:1 ratio) and occurred most frequently in individuals aged 40-70 years.
• One case demonstrated recurrence as a leiomyosarcoma.

Conclusions:

• Dermal angiomyomata in the upper extremity are more prevalent in middle-aged women.
• These benign tumors can be mistaken for other conditions, necessitating inclusion in the differential diagnosis.
• Awareness of this entity aids surgeons in diagnosing and managing painless masses of the hand, wrist, and forearm.
