Hand Dermatitis Secondary to Exposure to Butternut Squash

Area of Science:

• Dermatology
• Allergology
• Botany

Background:

• Cucurbita moschata, or butternut squash, is a widely consumed vegetable.
• Cutaneous reactions to butternut squash are infrequently reported in medical literature.
• Contact dermatitis is an inflammatory skin reaction often triggered by allergens or irritants.

Observation:

• A 28-year-old male presented with unilateral dry, flaking skin on his right hand and fingers.
• The patient had recent direct contact with butternut squash.
• Symptoms developed following exposure to the vegetable.

Findings:

• The clinical presentation and history strongly suggested allergic contact dermatitis.
• The unilateral nature of the dermatitis correlated with the localized contact with butternut squash.
• Cucurbita moschata was identified as the likely allergen responsible for the contact dermatitis.

Implications:

• This case expands the known spectrum of plant-based allergens causing contact dermatitis.
• Healthcare providers should consider butternut squash as a potential, albeit uncommon, cause of allergic contact dermatitis.
• Increased awareness may lead to better diagnosis and reporting of similar reactions.
