Calcospherules associated with juvenile hyaline fibromatosis.
Juvenile hyaline fibromatosis is a rare autosomal recessive genodermatosis that manifests with 1 to 5 cm skin tumors, gingival hyperplasia, osteolytic bone lesions, and joint contractures. The skin tumors are most often located on the head and periarticular extremities. A case of juvenile hyaline fibromatosis with typical skin tumors that on biopsy exhibited basophilic calcospherules is presented. Although noted in a single case, these structures may be a novel, yet helpful, diagnostic marker.
