Squamous Cell Melanoma

Squamous cell carcinoma begins in squamous cells, while melanoma begins in pigment-producing melanocytes. A lesion can be scaly, dark, raised, or changing, but those visible features cannot establish which cancer it represents. A pathology report identifies the cell type and guides staging. If a clinician suspects melanoma, the assessment may include the primary lesion, nearby lymph nodes, and other sites when indicated. [Melanoma](/conditions/melanoma/) provides condition-specific background.

If this phrase appears in a message, report, or conversation, ask the treating clinician to clarify the exact diagnosis and obtain the pathology wording. Do not delay review of a changing mole or pigmented lesion. Depending on the confirmed diagnosis, care may include [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/), [Sentinel Lymph Node Biopsy](/treatments/diagnostics-and-staging/sentinel-lymph-node-biopsy/), wider tumour removal, follow-up surveillance, or medicines such as [Immunotherapy](/treatments/systemic-therapy/immunotherapy/).

Arrange prompt assessment for a spot that changes in size, shape, colour, or sensation, or one that bleeds, crusts, or fails to heal. Seek urgent medical advice for severe pain, uncontrolled bleeding, new neurological symptoms, or rapidly worsening illness. These signs require attention but do not identify the diagnosis without examination.

Ask what the pathology report names, whether the sample was adequate, whether the lesion was fully removed, and what staging tests are appropriate. Ask which specialist will coordinate treatment, what follow-up is planned, and which new symptoms should be reported immediately.
