Primary Dermal Melanoma: A Rare Subtype of Melanoma and Clinical Mimicker of Basal Cell Carcinoma

Primary dermal melanoma (PDM) is a rare variant of melanoma. We present the case of a 76-year-old female diagnosed with PDM following initial suspicion of basal cell carcinoma, prompting extensive workup to exclude metastasis. This case demonstrates the diagnostic challenges and need for rigorous evaluation in suspected PDM cases. Current literature lacks definitive diagnostic markers for PDM, and we highlight the ongoing need for research and collaborative efforts between dermatology and oncology.
