What lesion may be in association with desmoplastic melanoma?

As such, the differential diagnosis is broad and includes: scar, dermatofibroma, neurofibroma or malignant lesions such as basal cell carcinoma, squamous cell carcinoma and amelanotic melanoma. Clinically, DM often presents as amelanotic nodules or plaques, or as ill-defined scar-like lesions (Figures 1-​ 2).

What can be mistaken for melanoma?

Top 5 Conditions Often Mistaken For Skin Cancer

  • Psoriasis. Psoriasis is a skin condition that is believed to be related to an immune system problem, which causes T cells to attack healthy skin cells by accident.

  • Sebaceous hyperplasia.
  • Nevus (mole)
  • Cherry angioma.

What is treatment for desmoplastic melanoma?

Treatment for desmoplastic melanoma First-line treatment of desmoplastic melanoma consists of surgical excision, completely removing the lesion along with a margin of tissue around it. The amount of healthy tissue removed is individualized and based on the depth and thickness of the patient’s melanoma.

What are the 5 warning signs of malignant melanoma?

What causes amelanotic melanoma?

Amelanotic melanoma may be a poorly differentiated subtype of typical melanoma.

  • Amelanotic melanoma may be a de-differentiated melanoma that has lost its normal phenotype.
  • Amelanotic melanoma cells may retain their melanocytic identity but gain the ability to form different phenotypes (multipotency)[3].
