Key result
FNA can misdiagnose chest wall intravascular papillary endothelial hyperplasia as adenocarcinoma due to overlapping cytology.

No
Intravascular papillary endothelial hyperplasia (IPEH) can be misdiagnosed as a malignancy such as adenocarcinoma on fine needle aspiration.
Requires histologic confirmation for chest wall FNA suggesting adenocarcinoma; leaves open incidence of IPEH misdiagnosis.
Intravascular papillary endothelial hyperplasia (IPEH) is an exuberant proliferation of endothelial cells that may occur within the lumen of a pre-existing vessel or vascular malformation.1 Although IPEH is regarded as a non-neoplastic reactive process, misdiagnoses as a malignancy have been reported, particularly based on fine needle aspiration (FNA) findings.2-4 We report a case of IPEH on the chest wall that was initially misdiagnosed as an adenocarcinoma on FNA.

Choi et al. (2013) conducted a case report in Intravascular papillary endothelial hyperplasia (IPEH) (n=1). Fine needle aspiration and surgical excision was evaluated on Diagnostic accuracy. Intravascular papillary endothelial hyperplasia of the chest wall can be misdiagnosed as adenocarcinoma on fine needle aspiration due to overlapping cytologic features.
