Malignant intertrigo: A subset of toxic erythema of chemotherapy requiring recognition

چکیده
MI: malignant intertrigo PPE: palmoplantar erythrodysesthesia SDRIFE: symmetrical drug-related intertriginous, flexural exanthema TEC: toxic erythema of chemotherapy INTRODUCTION Toxic erythema of chemotherapy (TEC) encompasses a broad spectrum of cytotoxic effects on the skin. Despite increasing awareness of TEC, such eruptions may remain unrecognized and subsequently result in unnecessary hospitalizations. Of the different variants of TEC, intertriginous eruptions have been reported using many terms, such as intertrigo dermatitis, intertriginous eruption of chemotherapy, flexural erythematous eruption, and intertrigo-like eruption associated with chemotherapy. Intertrigo is a broad term that refers to any inflammatory rash of closely opposed skin, typically presenting with varying degrees of erythema and maceration, and this particular type of TEC has not been identified with consistent nomenclature. We present 6 cases of this distinct subset of TEC, all occurring within a 7-month period at a single institution; these cases were initially unrecognized, resulted in hospitalization, and required inpatient dermatologic consultation to achieve a diagnosis. Although TEC is a clinically useful term intended to improve discernment of its noninfectious and nonallergic etiology, the loss of morphologic specificity may prevent its variants from being properly recognized, especially in the intertriginous regions. We therefore proposemalignant intertrigo (MI) as a useful and encompassing term describing toxic erythema of chemotherapy affecting the intertriginous skin.

متن کاملIntertrigo and secondary skin infections.
Intertrigo is a superficial inflammatory dermatitis occurring on two closely opposed skin surfaces as a result of moisture, friction, and lack of ventilation. Bodily secretions, including perspiration, urine, and feces, often exacerbate skin inflammation. Physical examination of skin folds reveals regions of erythema with peripheral scaling. Excessive friction and inflammation can cause skin br...

Hereditary mucoepithelial dysplasia (HMD) is a rare autosomal dominant disorder characterized by mucoepithelial disruption of the skin, hair and mucous membranes. It results from defective gap junction formation and leads to non-scarring alopecia, mucosal erythema, perineal erythematous intertrigo, involvement of the conjunctival mucosa, and pulmonary disease. We present a case of severe respir...
