Carotidoe tissue Benign vascular tumors Glomus tumor Author: Editorial Board Member Review: Glomus tumor [title] soft tissue Related topics: Page views in Obeidin F, Alexiev B. Accessed December 31st, Mesenchymal tumor composed of modified smooth muscle cells arising from the glomus body. Predominantly cutaneous, most common in subungual region of the finger but may occur anywhere Usually benign with very rare malignant variants Combination of glomus cells, smooth muscle cells and vasculature Round, punched out nuclei with amphophilic to eosinophilic stroma surrounding branching, capillary sized vessels Positive for SMA, MSA, calponin, h-caldesmon, collagen type IV; negative for cytokeratin and S Name differs based on morphology: Other benign neoplasms of connective and other soft tissue.

Estimated incidence of 1. Paroxysms of pain radiating away from the lesion, often out of proportion to the size of the neoplasm Pain can be elicited by changes in temperature or tactile stimulation Can be accompanied by hypesthesia, muscle atrophy or osteoporosis Some glomus tumors of the fingers and toes are associated with NF1 J Med Genet ; Images hosted on PathOut server: Contributed by Farres Obeidin, M.


Benign tumors have a small chance for recurrence if incompletely excised Atypical features found to correlate with adverse outcome, can be called glomus tumor of uncertain malignant potential: Images hosted on other servers: Fullness in posterior nail fold region.

Bulging mass with an irregular, nodular hemorrhagic cut surface Superficial lesions typically. Well circumscribed mass composed of 3 components: Branching capillary sized vessels lined by endothelial cells surrounded by collars of uniform glomus cells forming nests, sheets and trabeculae in a hyalinized or myxoid stroma Glomus cell has a round shape with indistinct borders with a rounded, sharply punched out nucleus in an amphophilic to eosinophilic cytoplasm Chromatin is homogenous and bland with inconspicuous nucleoli Very rare mitoses Symplastic glomus tumor: Marked nuclear atypia with no mitotic activity or other atypical features Does not affect prognosis Malignant glomus tumor Am J Surg Pathol ; Cohesive clusters of uniform round cells with scanty cytoplasm Background of scattered amorphous magenta colored material, blood and occasional inflammatory cells J Cytol ; Thick basal lamina surrounds individual glomus cells except at cellular junctions Pinocytic vesicles and myofibrils with dense bodies in the cytoplasm Cancer ; Myopericytoma and other pericytic tumors: Board review question 1.


Board review answer 1. This is a glomangioma, a variant of glomus tumor. It is a benign tumor and, if completely excised, surgical excision is essentially curative. The most common location is in the subungual region of the finger. Though it may show focal positivity for CD34, the staining for CD31 and ERG will be negative as the tumor cells are not vascular in origin.


Board review question 2. Which of the following molecular aberrations can be seen in glomus tumors?
