Yaranal PJ, Priyadarshini MM, Purushotham B - Indian J Dermatol (2015 Jan-Feb)

Bottom Line: In view, recent rise in human Dirofilaria repens infections in several regions of the world, is considered as emerging zoonotic infection transmitted to man by zooanthrophilic blood sucking insects.Most of the documented cases of human dirofilariasis recorded in India are ocular infections and very few cases of subcutaneous dirofilariasis have been reported.We hereby present a case of subcutaneous human dirofilariasis of forearm and also emphasize on increased awareness of this entity for clinicians and pathologists in the differential diagnosis of patients with subcutaneous nodules.

ABSTRACT
Human subcutaneous dirofilariasis (HSD) is a rare zoonotic filarial infection caused by filarial worms of the genus Dirofilaria. In view, recent rise in human Dirofilaria repens infections in several regions of the world, is considered as emerging zoonotic infection transmitted to man by zooanthrophilic blood sucking insects. Most of the documented cases of human dirofilariasis recorded in India are ocular infections and very few cases of subcutaneous dirofilariasis have been reported. We hereby present a case of subcutaneous human dirofilariasis of forearm and also emphasize on increased awareness of this entity for clinicians and pathologists in the differential diagnosis of patients with subcutaneous nodules.

Figure 1: Forearm mass: Soft, nontender, subcutaneous swelling measuring 3 × 2 cm, on the flexor aspect of the left forearm

Mentions: A 25-year-old male patient presented with painless mass in the left forearm for past 1 year and the mass was well-defined, nontender, and subcutaneous in location. On examination, the swelling was on the left side of his forearm and measuring approximately 3 × 2 cm [Figure 1]. His blood smear examination was negative for microfilaria. All other systemic examination and laboratory investigations were within normal limits. It was clinically diagnosed as sebaceous cyst and advised complete excision of the mass for definitive diagnosis. The excised mass was 2 × 2 cm and grey-white. The cut surface was grey-white with necrotic areas.
