| primary pyoderma | A pyoderma, such as impetigo, in which pus formation is an essential part of the disease. (05 Mar 2000) |
| secondary pyoderma | A pyoderma in which an existing skin lesion (eczema, herpes, seborrheic dermatitis, etc.) becomes secondarily infected. (05 Mar 2000) |
| pyoderma | <dermatology> Any purulent skin disease. Synonym: pyodermia. (18 Nov 1997) |
| pyoderma gangrenosum | An ulcerating condition of skin resulting in heaped borders with a typical appearance. Pyoderma gangrenosum appears to be mediated by the immune system, but the exact cause is unknown. The lesion(s) usually begin as a soft nodule on the skin which proceeds to ulcerate. The ulcer enlarges and the skin at the edge is purple-red. Ulcers can become quite large. This condition is associated with several other diseases, some of which are ulcerative colitis, crohn's disease, rheumatoid arthritis, leukaemia, and cryoglobulinaemia. Pyoderma gangrenosum is usually responsive to corticosteroids. (12 Dec 1998) |
| pyoderma vegetans | A benign fungating granulomatous mass caused by chronic pyogenic infection. Synonym: pyoderma vegetans. (05 Mar 2000) |
| anterior auricular branches of superficial temporal artery | <anatomy, artery> Distribution, auricle, earlobe and external acoustic meatus. Synonym: rami auriculares anteriores arteriae temporalis superficialis. (05 Mar 2000) |
| anterior superficial cervical lymph nodes | The lymph nodes in the subcutaneous tissue of the anterior region of the neck. Synonym: nodi lymphatici cervicales anteriores superficiales. (05 Mar 2000) |
| parietal branch of superficial temporal artery | <anatomy, artery> Branches coursing in relationship to and/or supplying the parietal lobe of the brain. Synonym: ramus parietalis arteriae temporalis superficialis. (05 Mar 2000) |
| medial crus of the superficial inguinal ring | Portion of the external oblique aponeurosis which passes medial to the superficial inguinal ring forming the medial boundary of the ring. Synonym: crus mediale annuli inguinalis superficialis. (05 Mar 2000) |
| membranous layer of superficial fascia | The membranous layer of the subcutaneous tissue in the urogenital region attaching posteriorly to the border of the urogenital diaphragm, at the sides to the ischiopubic rami, and continuing anteriorly onto the abdominal wall. Synonym: fascia perinei superficialis, Colles' fascia, Cruveilhier's fascia, membranous layer of superficial fascia. (05 Mar 2000) |
| greater superficial petrosal nerve | <anatomy, nerve> The parasympathetic root of the pterygopalatine ganglion; a branch from the genu of the facial nerve exiting via the hiatus of the facial canal and running in a groove on the anterior surface of the petrous part of the temporal bone beside the foramen lacerum to join the deep petrosal nerve, thus forming the nerve of the pterygoid canal, which passes through the pterygoid canal to reach the pterygopalatine ganglion. Synonym: nervus petrosus major, greater petrosal nerve. (05 Mar 2000) |
| polymorphic superficial keratitis | Epithelial degeneration occurring in starvation. (05 Mar 2000) |
| superficial | 1. Cursory; not thorough. 2. Pertaining to or situated near the surface. Synonym: superficialis. Origin: L. Superficialis, fr. Superficies, surface (05 Mar 2000) |
| superficial angioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment.
