**Core Concept**
Sago grain like lesions between fingers are a classic dermatological manifestation of a specific condition. These lesions are characterized by their granular, gritty texture and are often found in a specific location, typically on the palmar surface of the hands or fingers.

**Why the Correct Answer is Right**
The correct answer is a type of dermatitis that presents with these distinctive lesions. This condition is caused by a hypersensitivity reaction to certain allergens, such as metals or allergens in topical preparations. The sago grain like lesions are a result of the body's immune response, which leads to inflammation and the characteristic granular appearance. The lesions are often found in a specific location, such as between the fingers, due to the increased friction and pressure in this area.
