(Lane’s red palms)

Erythema palmare hereditarium is a benign, permanent condition that usually presents at birth.

It was first described by Lane in 1929.

It appears as a bright erythema usually restricted to the thenar and hypothenar eminences, palmar monticule and phalanges of both hands, unrelated to cold, heat or exercise.

It is aymptomatic without scaling, hyperkeratosis or hyperidrosis.

Autosomic recessive transmission has been reported, although familial cases suggest dominant transmission.

Differential diagnosis include:

• Liver cirrhosis

• Rheumatoid arthritis

• Thyrotoxicosis

• Diabetes mellitus

• Systemic lupus erythematosus

• Sarcoidosis

• Increased levels of estrogens
