Lymph node metastasis from a primary skin carcinoid tumour

Area of Science:

• Oncology
• Dermatology
• Endocrinology

Background:

• Carcinoid tumours are rare neuroendocrine neoplasms.
• They most commonly occur in the gastro-intestinal and respiratory tracts.
• Skin metastasis is uncommon, and primary cutaneous carcinoid tumours are exceedingly rare.

Observation:

• This report details a case of primary cutaneous carcinoid tumour.
• It is the sixth reported case of a primary skin carcinoid tumour.
• The tumour showed metastasis.

Findings:

• This is the first reported case of metastasis from a primary cutaneous carcinoid tumour.
• This finding expands the understanding of carcinoid tumour behaviour.
• It highlights the potential for cutaneous lesions to metastasize.

Implications:

• This case underscores the importance of considering metastasis in primary cutaneous carcinoid tumours.
• Further research is needed to understand the metastatic potential of these rare tumours.
• This finding may influence diagnostic and treatment strategies for primary cutaneous carcinoid tumours.
