[vc_row][vc_column width=”2\/3″][vc_column_text]Tyloma is a term derived from Greek, which literally means \u201cto harden\u201d. This term should replace callus, Clavus, Corno, terms that should no longer be used because they do not define a specific clinical entity.
\nThe clinical definition of Tyloma is: a small rounded area of hyperkeratosis at a plantar or dorsal rubbing point.
\nThe hallmark of tyloma is hyperkeratosis.
\nHyperkeratosis is the pathological thickening of the stratum corneum which can occur for a variety of reasons.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”1202″][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]In the case of tylomas, the stratum corneum thickens and becomes hard (hyperkeratotic) as a result of pressure or friction. Vital epidermal cells act to defend and protect themselves against these mechanical pressures which further accentuates the thickness of the stratum corneum.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_single_image image=”1204″ img_size=”650×500″][\/vc_column][vc_column width=”1\/2″][vc_empty_space][vc_single_image image=”1203″ img_size=”650×500″][\/vc_column][\/vc_row][vc_row][vc_column width=”2\/3″][vc_column_text]Plantar tylomas usually appear at the top of the metatarsals. This is especially true if the metatarsals are being pushed down due to a restriction in the tendons due to: hammer toe or loss of transverse arching or osteoarticular changes.
\nDorsal tylomas form in areas where the foot rubs against the shoe, often above the interphalangeal joints or on the external side of the fifth toe.
\nHeloma is the name given to the hyperkeratotic lesions that form between the interdigital spaces of the toes. Helomas have different pathogenesis and treatment from tylomas.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”1205″][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n
