What skin condition consists of tiny white or yellow papules on the nose and upper lip, appearing wetter than milia?

1. Sebaceous hyperplasia

2. Neonatal acne

3. Erythema toxicum

4. Dermal cysts

The correct answer is: Sebaceous hyperplasia

The condition described in the question features tiny white or yellow papules primarily located on the nose and upper lip, distinguishing it by its wetter appearance compared to milia. Sebaceous hyperplasia is characterized by small, benign, soft bumps that can appear on the skin due to enlarged sebaceous glands. These lesions are often present at birth or develop shortly after, reflecting the common presentation of the condition. Sebaceous hyperplasia is commonly found on the face and is particularly noticeable in newborns. The papules reflect an increase in sebaceous gland activity and give a moist appearance, which can be more pronounced than the dry, clogged presentation of milia. This fits well with the symptoms described in the question. In contrast, conditions like neonatal acne and erythema toxicum present differently and may not show the same characteristics of tiny papules or moisture. Dermal cysts typically are larger, firm lumps beneath the skin rather than tiny, surface-level papules. Thus, the defining features of the mentioned skin condition align accurately with sebaceous hyperplasia.
