A Case of Self-healing Juvenile Cutaneous Mucinosis / 대한피부과학회지

ABSTRACT

Self-healing juvenile cutaneous mucinosis (SHJCM) is a rare disorder of unknown origin that affects healthy children. It is characterized by multiplication of transient papules and nodules on the head and periarticular area. Histopathologically, lesions show mucin deposition in the dermis or subcutis. A 9-year-old male patient presented with multiple skin-colored papules and nodules on the face and both hands. These papules and nodules had appeared over the preceding months and had been increasing in number. He was otherwise healthy and had no underlying systemic disorders. Skin biopsy in the right thenar nodule revealed deposition of amorphous material stained positively with Alcian blue (pH 2.5) within the dermis and subcutis. Spontaneous resolution occurred over several months without sequelae.
