A case of familial cutaneous collagenoma.
Familial cutaneous collagenoma is a rare hereditary disease that is inherited in an autosomal dominant pattern. It is characterized by early onset of multiple, skin-colored, sometimes hypopigmented cutaneous nodules, which initially show a symmetrical arrangement on the trunk, and later on the neck and upper limbs. We report on a case of a 45-year-old female who presented with multiple oval to round hypopigmented papules measuring 5~15 mm on her trunk. Histopathologically, the lesions showed an increased amount of collagen fibers and decreased, fragmented elastic fibers in the dermis. The skin lesions were diagnosed as familial cutaneous collagenoma and no treatment was administered. To the best of our knowledge, our case is the first reported case of familial cutaneous collagenoma (FCC) in the Korean literature.
