Congenital or in early childhood. Occasionally also in old age.

Lower excrement (61%); here on the soles of the feet, more rarely on the field skin of the lower leg. Less frequently the palms of the hands are affected. Occasionally, other localizations have also been found (head and neck region, trunk).
Clinical featuresThis section has been translated automatically.
Slowly growing or constant, mostly painful, predominantly solitary (disseminated or systematized multiple hamartomas are rarer), gray-blue, blue-red or red-brown, firm to very rough plaque or corresponding nodules with a smooth or verrucous surface. Combinations with hypertrichosis and focal hyperhidrosis, as well as a depigmentosus and spilus n evus have been described (Yamamoto T et al. 2017). S.a.under Hamartoma, eccrines.
HistologyThis section has been translated automatically.
In the middle dermis lobularly grouped sweat glands and glandular ducts with eccrine and apocrine differentiation in close mixture with capillary and cavernous dilated vessels. Hyperplastic epidermis. If the hamartoma is found outside the inguinal skin, immature hair follicles may still be involved in this complex nevus.
