Sir,

We were enlightened by the response on our article by Rafael Dendai et al. [1]

We refreshed our knowledge through previous studies and found that infantile systemic hyalinosis and juvenile hyaline fibromatosis are allelic and intermediate phenotypes between these two disorders have been described. It has therefore been suggested that both disorders constitute parts of the same disease. [2] Thus, the adoption of another single term hyaline fibromatosis syndrome (HFS) seems to make the clinicopathological correlation in a clearer and simpler way for diagnosis and patients with HFS can be graded into mild, moderate, severe, and lethal subtypes. [3],[4] HFS is a human genetic disease caused by mutations in the anthrax toxin receptor 2 (cmg2) gene, which encodes a membrane protein thought to be involved in the homeostasis of the extracellular matrix. Little is known about the structure and function of the protein and the genotype-phenotype relationship of the disease. [5] No specific treatment is available. Early surgical excision is recommended by some authors in juvenile hyaline fibromatosis to prevent the appearance of new lesions, although excision may be followed by recurrences. Intralesional steroids may reduce the size of early lesions. Excision is indicated only for those lesions that either present a significant cosmetic problem or produce some degree of functional impairment. Capsulotomy of joints may show some temporary, beneficial effect; radiotherapy is ineffective. Gingival overgrowth may be treated with partial gingivectomy. Oral D-penicillamine has been used in some cases. Therapeutic trials with dimethyl sulfoxide, ketotifen and calcitriol are being done.
