Pyogenic melanoma: understanding the term and next steps

Pyogenic granuloma is a benign, blood-vessel-rich growth. Melanoma is a skin cancer that begins in pigment-producing cells. A red, crusted, ulcerated, or bleeding melanoma can resemble other lesions, while a pyogenic granuloma can also change quickly. A symptom does not establish the condition: melanoma can present with a changing pigmented or non-pigmented lesion, but only clinical assessment and, when needed, tissue examination can clarify the diagnosis.

If melanoma is confirmed, clinicians assess the primary lesion and whether nearby lymph nodes or distant areas need evaluation. The treatment plan depends on the pathology and stage.

Book a prompt dermatology appointment for a new, changing, bleeding, or non-healing lesion. Do not pick it or use a home treatment that could alter the surface. The clinician may recommend [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/) or [Skin Cancer Surgery](/treatments/surgical-dermatology/skin-cancer-surgery/) to obtain or remove tissue. Confirmed melanoma may lead to discussion of [Sentinel Lymph Node Biopsy](/treatments/diagnostics-and-staging/sentinel-lymph-node-biopsy/), [Immunotherapy](/treatments/systemic-therapy/immunotherapy/), or structured [Follow-Up After Cancer Treatment](/treatments/survivorship-and-rehabilitation/post-treatment-surveillance/), depending on findings.

Seek urgent care for bleeding that does not stop with firm pressure, rapidly worsening pain or swelling, or symptoms such as new weakness, confusion, or a severe headache. Otherwise, arrange timely assessment rather than waiting for a lesion to settle on its own.

What diagnosis best fits the lesion? Is a biopsy or complete excision needed? If melanoma is found, what does the pathology show about depth and spread, and which specialist will coordinate the next steps?
