Overview
Sinonasal mucosal melanoma is biologically different from common skin melanoma and requires expert pathology, complete staging, and coordinated local and systemic treatment planning. Because it develops inside the nose, it often causes one-sided nasal blockage and nosebleeds and may not be visible from the outside. Care is multidisciplinary and individualized, and because recurrence is a concern, long-term surveillance is important. This page is educational and does not replace specialist evaluation.
What this evaluation should clarify
A focused evaluation is designed to answer a few key questions:
- What objective evidence distinguishes sinonasal mucosal melanoma from look-alike conditions?
- Which anatomic, inflammatory, dental, neurologic, infectious, or tumor-related factors may be contributing?
- Which medical, procedural, surgical, or multidisciplinary path best fits the findings and your goals?
Living with sinonasal melanoma? The next step is a quiet, unhurried conversation.
Evaluation and treatment pathway
Care generally follows a stepwise path:
- Clarify the symptom pattern, duration, triggers, prior treatment, operations, medications, and relevant medical history.
- Diagnosis requires biopsy and expert pathology, with imaging to define local extent and staging to assess regional and distant disease. Molecular testing and pathology interpretation may affect systemic options in selected cases.
- Identify important look-alikes, complications, and contributors before settling on a definitive diagnosis.
- Treatment may include surgery, radiation, and systemic therapy, chosen according to resectability, extent, molecular and clinical factors, prior treatment, and patient goals. Close surveillance is important because recurrence can be local or distant.
- Set a measurable follow-up plan covering symptom goals, objective reassessment, medication response, and imaging or surveillance when appropriate.
How mucosal melanoma differs from skin melanoma
Sinonasal melanoma is a mucosal melanoma, arising from pigment cells in the lining of the nose and sinuses rather than from the skin. Unlike skin melanoma, it is not linked to sun exposure, it is often diagnosed at a more advanced stage because it is hidden inside the nose, and it is staged and treated differently.
One-sided obstruction and bleeding
Because it grows inside the nose, sinonasal melanoma commonly causes one-sided nasal blockage and recurrent nosebleeds. Some tumors are darkly pigmented while others are not, so appearance alone does not rule it out. Persistent one-sided nasal symptoms should be evaluated.
Biopsy, imaging, and staging
Diagnosis involves nasal endoscopy, a biopsy with expert pathology review, and imaging with CT and MRI to define the tumor's extent. Additional imaging is used for staging to assess whether the cancer has spread. Accurate pathology is important because melanoma can resemble other tumors.
Surgery and margin planning
Surgery to remove the tumor is the cornerstone of treatment for many patients, with careful planning to achieve clear margins while protecting nearby structures such as the eye and skull base. Depending on the tumor, surgery may be endoscopic, open, or a combination.
Radiation and immunotherapy or systemic therapy
Radiation therapy is frequently added after surgery to improve local control. Immunotherapy and other systemic treatments play an increasing role, particularly for more advanced or spread disease, and are coordinated with medical oncology. The plan is individualized.
Recurrence and surveillance
Sinonasal melanoma can recur locally or spread elsewhere, so long-term surveillance with examination and imaging is an essential part of care. Ongoing follow-up allows recurrence to be identified and addressed as early as possible.
What to bring to your consultation
Bringing the right records helps make the visit focused and useful. Where available, gather:
- Imaging files and reports, including CT and any MRI
- Endoscopy or operative findings from prior care
- Pathology results from any biopsy or surgery
- Relevant laboratory results
- Notes from prior treatment and a current medication list
- The specific question you would like answered
When to seek urgent care
Major bleeding, breathing difficulty, acute vision change, severe headache, rapidly progressive neurologic symptoms, or marked clinical decline require urgent care.
