Abstract:
Background:The forehead is a region connected to the scalp and is accompanied by various structures. In some tumors, the pattern of development may differ from that of other anatomical sites. When a noninflammatory skin-colored tumor develops on the forehead, it is difficult to diagnose accurately.
Objective:This study aimed to identify the epidemiologic data and clinical features of noninflammatory skin-colored tumors of the forehead.
Methods:We retrospectively reviewed the medical records of 200 patients with noninflammatory, skin-colored tumors diagnosed after skin biopsy over a period of 11 years. We evaluated tumor prevalence, clinical features, and differences according to sex and age. If the tumor was large and deeply located, a radiologic study was performed.
Results:Of the 12 different histopathologic results, lipoma (52.0%) was the most frequent, followed by epidermal cyst (17.0%), osteoma (13.5%), steatocystoma (6.0%), and pilomatricoma (3.5%). Statistical analysis showed that females were dominant in the osteoma group. For an accurate diagnosis, 25 of the 52 patients who underwent computed tomography were diagnosed with lipoma, and 19 (76.0%) of them were identified as deep-seated lipoma.
Conclusion:The most common tumor among noninflammatory, skin-colored tumors of the forehead was lipoma.When they occur on the forehead, the proportion of deep-seated lipomas is higher than that at other sites. In the case of a solid and fixed tumor, a deep-seated lipoma should be considered. Computed tomography should be performed in addition to ultrasonography because the sensitivity of ultrasonography for the diagnosis of deep-seated lipoma is unsatisfactory.
