A superficial acral fibromyxoma is a type of myxoma and is a rare cutaneous condition characterized by a mesenchymal neoplasm that typically occurs on the digits of middle-aged adults.
[2] It begins as a slow-growing, solitary nodule limited to the dermis and subcutaneous tissue, and it is typically painless.
[6] A histologic examination reveals stellate and spindled fibroblast-like cells proliferating moderately within a myxoid and/or collagenous matrix with prominent microvasculature.
[7] Differential diagnosis includes periungual and subungual fibroma, acquired digital fibrokeratoma, superficial angiomyxoma, myxoid neurofibroma, dermal mucinosis, sclerosing perineuroma, low grade fibromyxoid sarcoma, myxoid dermatofibrosarcoma protuberans, fibroma of tendon sheath, giant cell tumour, glomus tumour, fibrous histiocytoma, cutaneous myxoma and inflammatory myxohyaline tumour of distal extremities.
[7] Complete excision, which typically prevents recurrence, and regular follow-up are recommended surgical therapy techniques.
