1. A familial disease causing dissolution of the tips of the bones in the extremities of young children. There is no history of trauma, and spontaneous amputation does not occur. Its cause is unknown.
2. An occupational disease seen in workers who come in contact with vinyl chloride polymerization processes. It is marked by Raynaud's phenomenon, scleroderma-like skin changes, and radiological evidence of bone destruction of the distal phalanges of the hands. Recovery follows removal from exposure.

Although both HMS and PLS share the common pathogenomic features of PPK and severe periodontitis6,7 and are allelic variants of cathepsin C gene mutations6,8, a number of additional findings are reported in HMS including onychogryphosis (curved nails), arachnodactyly (spider fingers/ elongated and slender shaped fingers and toes), acro-osteolysis (tappered pointed distal phalangeal ends due to osteolysis), pes planus (flat foot), occasionally hyperkeratotic psorisiform lesions with an erythematous background on the extensor surfaces of elbows and knees9,10,11,12 and rarely destructive arthritis of the wrists and shoulder joints.
Other features such as acro-osteolysis and pes planus were absent in proband but present in the elder sibling.

Primary HOA or pachydermoperiostosis is a rare hereditary disorder characterized by digital clubbing, subperiosteal new bone formation, acro-osteolysis, hypertrophy of soft tissues and glands, particularly in the face and scalp resulting in wrinkling of skin.
in 1991 proposed diagnostic criteria for PDP i) major criteria: digital clubbing, periostosis, and pachydermia and ii) minor criteria: seborrhea, hyperhidrosis, folliculitis, arthritis or arthralgia, gastritis or gastric ulcer, acro-osteolysis, neurovegetative syndrome, hypertrophic gastropathy and cutis verticis gyrate.
