The dermis is the layer of skin between the epidermis and subcutaneous tissue, and comprises two sections, the papillary dermis and the reticular dermis. [10] The superficial papillary dermis interdigitates with the overlying rete ridges of the epidermis, between which the two layers interact through the basement membrane zone. [ 10 ]
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
The symptoms of a disseminated gonococcal infection include fever, tenosynovitis, arthralgias, and a few vesiculopustules over the distal ends of the extremities that may have purpura or hemorrhagic necrosis. The symptoms of Rocky Mountain Spotted Fever, which is spread by ticks, include photophobia, headache, fever, chills, and myalgias.
