From April 2003 to March 2007, we examined 378 patients self-diagnosed
with keloids or hypertrophic scars. We detected four other diseases
(1.06%) in the group of patients. All tumors were benign: apocrine
cystadenoma, adult-onset juvenile xanthogranuloma, mixed tumor, and
chronic folliculitis. Although we detected no malignancies, malignant
tumors can resemble keloids or hypertrophic scars, including
dermatofibrosarcoma protuberans (DFSP) and fibroblastoma, and
differential, or exclusive, diagnosis of diseases similar to keloids and
hypertrophic scars is important. We found the following considerations
important in the examination of keloids or hypertrophic scars: biopsies
should be conducted in anomalous cases since malignant disease might be
an initial or secondary problem, steroid injection should be performed
only after careful consideration since malignancy or infections might be
present, and the presence of bacterial or fungal infection should be
investigated. |
