Invasive squamous cell carcinoma within a plaque of circumscribed palmar hypokeratosis
Circumscribed palmar hypokeratosis (CPH) is a localized disorder of epidermal keratinization that is presented as a well-delimited, depressed, erythematous plaque on the palms or on the soles. It is histopathologically characterized by an abrupt thinning of the corneal epidermal layer. CPH is considered a benign condition, but a few cases with dysplastic changes/carcinoma in situ in the hypokeratotic epidermis have been described. We report hereby a case of invasive squamous cell carcinoma developed within a plaque of CPH. The pathogenesis of the malignant changes in this disorder remains to be clarified. Clinicians should be aware of the potential for developing malignancy in CPH and carry out a closer follow-up of this disorder.
期刊介绍:
Journal of Cutaneous Pathology publishes manuscripts broadly relevant to diseases of the skin and mucosae, with the aims of advancing scientific knowledge regarding dermatopathology and enhancing the communication between clinical practitioners and research scientists. Original scientific manuscripts on diagnostic and experimental cutaneous pathology are especially desirable. Timely, pertinent review articles also will be given high priority. Manuscripts based on light, fluorescence, and electron microscopy, histochemistry, immunology, molecular biology, and genetics, as well as allied sciences, are all welcome, provided their principal focus is on cutaneous pathology. Publication time will be kept as short as possible, ensuring that articles will be quickly available to all interested in this speciality.
