Traumatic hematoma in a palmoplantar wart mimicking acral lentiginous melanoma

Intra- and subcorneal hematoma, a skin alteration seen palmar and plantar after trauma or physical exercise, can be challenging to distinguish from in situ or invasive acral lentiginous melanoma. Thus, careful examination including dermoscopic and histologic assessment may be necessary to make the correct diagnosis. We here present a case of a 67-year-old healthy female patient who presented with a pigmented plantar skin alteration. Differential diagnoses included benign skin lesions, for example, hematoma or melanocytic nevus, and also acral lentiginous melanoma or melanoma in situ. Since clinical and dermoscopic examinations did not rule out a malignant skin lesion, surgical excision was performed and confirmed an intracorneal hematoma. In summary, without adequate physical trigger, it may be clinically and dermoscopically challenging to make the correct diagnosis in pigmented palmar and plantar skin alterations. Thus, biopsy or surgical excision of the skin alteration may be necessary to rule out melanoma.

Traumatic hematoma in a palmoplantar wart mimicking acral lentiginous melanoma

Abstract: We describe a case where a secondary traumatic hematoma in a pre-existing palmoplantar wart of the sole was presenting a diagnostic dilemma where it simulated an acral lentiginous melanoma and was managed successfully with wide excision and local skin flap.
