Carcinoma cuniculatum originating from intertriginous lesions

Area of Science:

• Dermatology
• Oncology

Background:

• Intertriginous lesions are common skin conditions often treated with standard antifungal or antibacterial therapies.
• Long-standing or recalcitrant intertriginous lesions can present diagnostic challenges.

Observation:

• Three cases of carcinoma cuniculatum are presented, originating in intertriginous areas.
• These malignancies initially presented with symptoms resembling common conditions like athlete's foot (tinea pedis).

Findings:

• Carcinoma cuniculatum is a rare, slow-growing squamous cell carcinoma.
• The study highlights the potential for this malignancy to arise from seemingly benign, persistent intertriginous dermatitis.

Implications:

• Cutaneous malignancy should be considered in the differential diagnosis of intertriginous lesions that do not respond to conventional treatments.
• Early recognition and biopsy are crucial for accurate diagnosis and management of these rare skin cancers.
