Objective:
Metastatic cutaneous neoplasms may be difficult to differentiate from primary cutaneous neoplasms. Herein, we report an unusual case of metastatic cutaneous carcinoid tumor mimicking an adnexal poroid neoplasm.
Methods:
A 53-year-old male man presented with a neoplasm on the vertex of the scalp, clinically resembling a pigmented basal cell carcinoma.
Results:
A shave biopsy was suggestive of an apocrine poroma, however, a metastatic carcinoma could not be excluded. After acquiring additional clinical information and the complete excision of the neoplasm, further immunohistochemical stains supported the diagnosis a metastatic carcinoid tumor.
Conclusion:
To our knowledge, this is the first case of metastatic carcinoid tumor reported that has mimicked a poroid neoplasm.
