Superficial acral fibromyxoma, also known as digital fibromyxoma, is a benign soft tissue tumor. The acral regions, including the palms, soles, fingers, toes, and nail units, are the commonly affected locations. The subungual region of the great toe is the most common site reported in current literature. The tumor is slowly progressive and benign in nature. Histology commonly reveals a fibromyxoid neoplasm with immunoreactivity to CD34 and CD99 markers. We present the case of a 39-year-old female with a nine-year history of repetitive digital trauma presenting with superficial acral fibromyxoma of the thumb-nail bed. Our case is unique due to the tumor location and the patient's prior long history of trauma to the tumor site. [ABSTRACT FROM AUTHOR]

Adhesive tape has been used in the scientific study of human skin for more than 90 years. Use of the tape stripping method in dermatology has aided the research and diagnosing of different skin diseases. Basic science, identification, and therapeutic interventions in skin diseases, such as psoriasis, atopic dermatitis, nonmelanoma skin cancer, and melanoma, have been studied using this technique. Among many promising applications that will be discussed throughout this contribution, the pigmented lesion assay will be discussed in depth in relation to melanoma. This product carries considerable and significant research toward early detection of melanoma. Tape stripping is unique and advantageous in its ability to provide a nonsurgical approach to evaluating the human epidermis. The cellular and molecular components of the skin are used to diagnose different skin conditions without invasive skin biopsy. [ABSTRACT FROM AUTHOR]
