Abstract
Desmoplastic melanoma is an extremely rare subtype of malignant melanoma comprising only 1% of all the cutaneous melanomas. Being amelanotic and owing to its histopathological features of spindle cells lying in a collagenized stroma, it is often misdiagnosed as a dermatofibroma or scar tissue. The present case study describes a case of desmoplastic melanoma of the chest wall where the final diagnosis could be arrived at only after an extensive immunohistochemical panel to exclude other spindle cell proliferations.

Abstract
Abstract
Desmoplastic malignant melanoma is a rare variant of spindle cell melanoma commonly seen in older adults on sun-exposed areas. It accounts for 1–4 % of all cases of cutaneous melanoma. The common location of the desmoplastic melanoma is the head and neck region, whereasother sites are less common. A 45-year-old male presented with an proliferative growth on nose, after a trauma that was diagnosed as tumor. Histopathological examination with the help of wide panel of immunohistochemical methods and with emphasis on SOX10, was, after a broad diferential diagnosis concluded as a desmoplastic melanoma.

Abstract
Desmoplastic malignant melanoma (DMM) is an extremely rare subtype of cutaneous melanoma that has diverse clinical presentations. We describe the unique case of a 57-year-old man presenting with empyema secondary to vascular occlusion from metastatic DMM. Only two other cases of DMM presenting as a lung mass have been previously reported in the literature. This report highlights potential insidious pathology of DMM, which requires a high clinical suspicion to properly diagnose and manage.
