Hyperkeratosis lenticularis perstans (Flegel's disease) - successful treatment with topical corticosteroids.

Flegel's disease, also known as hyperkeratosis lenticularis perstans, is a rare skin disease characterized by small, red-brown, hyperkeratotic, papules that are usually located on the lower extremities. The diagnosis is based on the clinical appearance in association with the typical histologic features of orthohyperkeratosis and a subepidermal band-like infiltrate. Treatment is difficult and rarely fully effective.

Ossification of the auricle.

The auricle is a flexible structure because it is formed by elastic cartilage. In the rare occurrence of ectopic auricular ossification, however, the cartilage is replaced by lamellar bone and becomes petrified. Such unphysiological replacement has been reported in association with local trauma, inflammation, systemic diseases, and hypothermia.
