ABSTRACT
A glomus tumor, is a benign neoplasm, which is derived from a normal glomus body, and participates in thermal regulation. This tumor is relatively uncommon and usually occurs in the peripheral soft tissue, most frequently in the digits, where the glomus bodies are normally present. We experienced a case of a glomus tumor in a 60-year-old man who had a solitary, dome-shaped, grayish blue-colored papule on his back. This was present in an area where a normal glomus body might not usually occur.

Dopamine is a catecholamine used in the treatment of circulatory shock of various etiologies. The usual dose range used is from 1 to 25 ug/kg/min. When used at higher doses, the prominent effect of dopamine on the vasculature is vasoconstriction induced by stimulation of alpha-adrenergic receptors. We report a case of dopamine gangrene. The gangrene developed on the injection site in the right dorsum of foot in a 43-year-old man during infusion of dopamine for treatment of septic shock. The gangrenous lesion healded after change of injection site to subclavian vein. The dosage of dopamine was not higher, we think that the gangrene developed due to the local vasoconstriction caused by dopamine leakage from the vessels.
