Cytomorphology of a metastatic basaloid squamous carcinoma from an intranasal tumor: a diagnostic mimic for a neuroendocrine tumor--a rare case report.

摘要

Basaloid squamous carcinoma (BSCC) is an uncommon variant of a squamous carcinoma (SCC) and is believed to be associated with a relatively aggressive course, including in locations like in head and neck area. There is limited documentation of its cytomorphological features, especially from metastatic deposits in lymph nodes and soft tissues from an intranasal tumor, where an index of suspicion for its diagnosis is lower than a malignant neu-roendocrine tumor. A 49-year-old woman referred to us with enlarged left-sided, level II cervical lymph nodes. Her earlier surgical records across the hospital data information system revealed that she had undergone an endoscopic endonasal resection of right inferior, posterior, and superior turbi-nates; floor mucosa, nasal septum, along with right-sided ethmoidectomy for an intranasal tumor that was initially biopsied, elsewhere.
