Cytologic analysis of a glomus tumor in the left second toe: Case report

We present a 66‐year‐old female with a glomus tumor diagnosed by fine‐needle aspiration (FNA) at the subungual region of her left second toe. Cytologic findings include cohesive clusters of round, uniform cells with scant cytoplasm. Nuclei were monotonous with fine chromatin. No cellular atypia, nuc...

Description
Summary:We present a 66‐year‐old female with a glomus tumor diagnosed by fine‐needle aspiration (FNA) at the subungual region of her left second toe. Cytologic findings include cohesive clusters of round, uniform cells with scant cytoplasm. Nuclei were monotonous with fine chromatin. No cellular atypia, nuclear inclusions, mitotic figures, nor nucleoli were identified. Cells were surrounded by thick wisps of magenta colored myxoid material reminiscent of a pleomorphic adenoma. Few spindle shaped cells could be seen near the border of the tumor clusters. Staining was positive for alpha‐smooth muscle actin. This case report presents one of few FNA diagnosed glomus tumors.
