Abstract:
The etiology of skin malignancies is evaluated as multi-factorial. The human phenotype, syndromes, precursor lesions, and immunologic differences play as risk factors as well as environment. Twenty-seven patients with multi-centric skin malignancies investigated as if having predisposing syndromes. The etiological factors and the classification of skin malignancies are assessed. We last discussed about the management options. The mean age was 47 (9-91). Men to women ratio was 16:11. Four out of 27 patients having multi-centric skin malignancies were realized as syndromic. The localization of these tumors was entirely at the head and neck region. Ninety-eight areas were distinguished as having skin malignancies in 27 patients. Sixty-one incisional biopsies for type analysis and 37 excisional biopsies were handled. Of the 98 malignancies, 24 were squamous cell cancer, 67 were basal cell cancer, and seven were basosquamous cell cancer pathologically. Wound closures were carried out as primarily in 39 excisions; using skin grafts in 21 excisions, local flaps in 28 excisions, and distant flap procedures in 10 regions. The follow-up period was between six and 25 months. No complications or recurrences were seen. Eight patients applied with new lesions on new regions, six patients had excision, and two were treated with radiotherapy.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
