Clinical, histopathological and immunohistochemical features of glomus tumor of the nail bed

The glomus tumor is an uncommon benign neoplasm of glomus cells. In the majority of the cases it is presented as a solitary painful papule in the subungual region. We report a rare case of a patient with two individual synchronous glomus tumors under the nail bed of the same finger.

Abstract Purpose Glomus tumors are rare vascular pathologies characterized by a triad of symptoms: tenderness, pain and cold intolerance. In the hand they are highly concentrated under the nail bed. In this retrospective study, we aimed to present a topographic map of the location of glomus tumors in the nail bed and a map-based surgical approach algorithm to the subungual glomus tumors. Methods We prepared a nail bed map with 6 zones and named these zones as ulnar distal, ulnar proximal, central distal, central proximal, radial distal and radial proximal. With respect to the tumor location and the used surgical approach we retrospectively evaluated the intraoperative photos and the hospital records of patients who were operated between 2008–2019 and had the pathological diagnosis of glomus tumor. The examination records of the postoperative first year were evaluated for each patient retrospectively. A descriptive statistical analysis was performed. In addition we analyzed the described surgical approaches to excise a glomus tumor in the nail bed. The described approaches and the approaches used by us were matched with the localisation of the tumors in this study developing an algorithm for the surgical approach depending on the localisation of the nail bed glomus tumor. Results Finally 44 patients had inclusion criteria. The distribution of the glomus tumor was as follows: 2 were on ulnar distal (4.5 %), 9 on ulnar proximal (20.5 %), 1 on central distal (2.3 %), 18 on central proximal (40.9 %), 4 on radial distal (9.1 %) and 10 were on the radial proximal zones (22.7 %). 4 lateral approaches, 1 nail sparing and 39 transungual approaches were performed. We had one recurrence in a male patient operated by transungual approach. Conclusion Glomus tumors are mostly located on the central proximal part of the nail bed. Our glomus map and the algorithm we described might be helpful for the selection of the surgical approach for the glomus tumor.

Background: Although there are various surgical methods for subungual glomus tumor treatment, there is no consensus on the optimal surgical approach. Methods: We analyzed the outcomes of 15 patients treated with partial nail plate excision technique. The medial or lateral section of the nail plate was excised longitudinally based on the tumor location. After incision of the nail bed and tumor removal, the matrix was repaired carefully. Results: In this study, 15 people, including 11 men and four women, were studied. The mean onset of symptoms until diagnosis was 88 months. In the postoperative evaluation, the mean follow-up was 20 months. Two patients had recurrent tumors, and one had postoperative nail deformity. Conclusion: Meticulous nail bed repair and complete tumor excision are key treatment points needed to prevent nail deformity and recurrence.

Histopathologic Findings

Glomus tumors are relatively rare benign tumors originated from normal glomus bodies. These tumors make up approximately 2% of all hand tumors and are most commonly found in the nail matrix and proximal nail bed of the hands. Histopathologically, they are classified into solid glomus tumor, glomangioma, and the least common type glomangiomyoma. Here we report an unusual case of subungual glomangiomyoma of the toe with dermatoscopic and histopathologic findings.

History Of ◽

Glomus Body

Glomus tumors closely resemble the normal glomus body and have a predilection for skin and subcutaneous tissue. Clinically, Glomus tumors are present on the nail bed and are of less than 1 cm. We report a case of a male who presented with a 3 month history of swelling in the left thumb which was mildly tender. The swelling measured 6 x 6.5 cm. On microscopy the tumor showed mild atypia with increased mitotic activity. These features, by current definition, would suggest uncertain malignant potential.

Point Tenderness

Glomus tumors are benign neoplasms that develop from normal glomus bodies. These tumors are most commonly found in the nail bed of the hands and are characterized by point tenderness, and temperature sensitivity. Histologically, they are classified into three groups, the least common is glomangiomyoma, which is a variant distinguished by its predominant smooth muscle cellular content. This report describes a patient with a subungual glomangiomyoma that was surgically excised with a favorable outcome. The tumor is unusual for this location; a location common for typical glomus tumors. It presented without the typical associated symptoms of point and temperature sensitivity. This may suggest that the histological type may be more important in predicting the clinical presentation than the anatomical location of the glomus tumor.
