Micrococcus spp. are obligate aerobes that inhabit human skin. Staphylococcus spp. also inhabit human skin, but they are facultative anaerobes. They ferment sugars, producing lactic acid as an end product. Many of these species produce carotenoid pigments, which color their colonies yellow or orange. Staphylococcus aureus is a major human ...
[9] commonly presents as a painless, red and brown or red and yellow, ulcerated papule on the head or neck and may mimic nonmelanoma skin cancers, molluscum contagiosum, adnexal neoplasms, or pyogenic granuloma. [2] [6] The mean lesion size of periocular and extraocular SGc is approximately 1.4 cm. [2]
