Human subcutaneous dirofilariasis: the 'migrating' skin tumor

Area of Science:

• Medical Parasitology
• Dermatology
• Infectious Diseases

Background:

• Dirofilariasis is a zoonotic parasitic disease typically transmitted by mosquitoes.
• Subcutaneous dirofilariasis presents as a migrating nodule, often leading to diagnostic delays.
• Facial involvement is common, necessitating specialized treatment approaches.

Observation:

• A 46-year-old woman experienced prolonged facial pain and discomfort.
• Diagnosis of subcutaneous dirofilariasis was established months after symptom onset.
• The patient presented with a characteristic migrating subcutaneous nodule.

Findings:

• Subcutaneous dirofilariasis was confirmed as the cause of the patient's symptoms.
• The case highlights the importance of considering dirofilariasis in atypical presentations.
• Prompt diagnosis is essential for effective management.

Implications:

• Dirofilariasis should be considered in the differential diagnosis of migrating subcutaneous nodules, regardless of geographic location.
• Plastic surgery is the preferred treatment modality for facial subcutaneous dirofilariasis.
• Increased awareness can improve patient outcomes and reduce diagnostic delays for this rare condition.
