Ans:A.)Nevus Anemicus.
Nevus anemicus
- It is a congenital vascular anomaly that presents clinically as a hypopigmented macule or patch.
- The lesional pallor is due to a localized hypersensitivity to catecholamines with resultant vasoconstriction.
- Patients with nevus anemicus typically present with an asymptomatic pale macule or patch that has been present since birth and grows with the child.
- Clinically, nevus anemicus is a circumscribed, rounded, oval or linear pale macule or patch with irregular margins that may be surrounded by satellite macules.
- Lesions may be single or multiple and may be located on any part of the body, but most lesions commonly are found on the upper chest.
- Nevus anemicus occurs more frequently in females and is usually asymptomatic.
