An amelanotic malignant melanoma masquerading as hypergranulation tissue.
Summary
Amelanotic malignant melanoma, a rare skin cancer, can mimic ingrown toenail complications. Early diagnosis is crucial to prevent serious health consequences from this nail bed tumor.
Area of Science:
- Oncology
- Dermatology
- Podiatry
Background:
- Amelanotic malignant melanoma is a rare variant of melanoma lacking pigment.
- Nail apparatus tumors can present with diagnostic challenges.
- Ingrown toenails are a common condition often leading to secondary changes.
Observation:
- A case of amelanotic malignant melanoma in the hallux nail sulcus was initially misdiagnosed.
- The lesion presented as hypergranulation tissue, similar to that seen with ingrown toenails.
Findings:
- Histopathological examination confirmed amelanotic malignant melanoma.
- The clinical presentation mimicked granulation tissue secondary to an ingrown toenail.
Implications:
- This case underscores the importance of considering amelanotic malignant melanoma in the differential diagnosis of nail sulcus lesions.
- Delayed diagnosis of nail bed melanoma can lead to advanced disease and poorer prognosis.
- Dermatological and podiatric clinicians must maintain a high index of suspicion for melanoma in persistent or atypical nail lesions.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
